Fuel Consumption VY SS SERIES II

[mass69]

Hi guys just a quick question which im sure that have been covered so forgive me for asking.

I recently purchased VY SS and i cant believe how much it drinks im getting 18L/100km sometimes 17.8 or so the computer says when I press Mode

All up im Not getting over 400km out of a full tank!! is this normal
some people are telling me i need to get my car tuned!! its only done 38,000 Kms....I feel like selling the damm thing already!

Thanks

[mdafter]

city driving stop start that's about right, a tune can improve fuel economy especially on an auto

[LS1Grange]

yeah that sounds about right if you are doing alot of city driving. Get her out on the open road if you want some relatively good economy. Getting a tune/edit, intake and exhaust mods can improve things also. If I do alot of city driving I'll struggle to get 450km out of a tank. But on long country drives I'll get 650 - 700 easy

Pretty normal for sydney. I was 19L/100km when stock.


I feel like selling the damm thing already!

Yet you only recently purchased a V8? I hate to sound like a parent ... but what were you thinking? :p :stick:

[vyssbeast]

Yeh mate thats normal ... with an edit im getting round 450 averaging 16L/100Km but thats due to ALOT of WOT ... so im pretty happy with that

If i drive sedatly ill get more ... but meh its more fun this way

If you have a huge need for fuel economy, talk to oztrack and ask him to specifically focus on that as part of his tune ... You will be surprised at how different of a car it is afterwards not to mention the reduced fuel usage

[ace078]

I have all the usual mods and get around 17lt/100kls total city driving, and as said before, plenty of WOT at every chance. I'm happy.

[JBonDSS]

Mass69, is it manual or Auto,

I found i had the same problem with my VX SS S1 m6, basicly turned out i was getting to 6th to early, changerd my driving pattern to only get into 6th after 90kph & that gained my 50+km per tank

Stock tune too.

Sell it then, it's never going to be great on petrol in the city.

Jesus I struggle to get 400ks out of a full tank Suburban driving (meaning: not stopping and starting every minute) though I do have a heavy foot :love:

I know you have a mafless tune but fark me dead I wish I could get 450ks, maybe I need to get a mafless tune from Oztrack in my current car to get more ks out of a tank and better performance with an OTRCAI. I am getting tempted now but I want to sell my car don't I? My mail order maf tune is starting to shit me now :cussing:

Dane.

[mass69]

Thanks for the response guys appricate it. I just was not sure if this was normal as some say they get 13L/100KM!! dont know how..guess i will just live with it for the moment : )

JBon to answer you question it is a manual mate.

They drive like:limpy:

[zorro]

mass69, it might pay to disconnect the battery for a few hours and reconnect. drive like a grandma for a tank of fuel and you may get a bit better economy due to pcm learning your driving habits.

I get 500+klms from my VU M6 ute, with extractors/exhaust, 3.91s occasional WOT adventures and no tune. It seems a mixed bag of fuel consumption for standard or slightly modded LS1s so I wouldn't be worried.

City driving is the big killer, if you can restrain from getting on the berries 2500rpm gear changes will keep the fuel consumption down. If it is a big issue go get a tune with fuel consumption being the main objective, or even better buy a postie bike for the weekday trip to work.

if it makes you feel any better i only got 400 km to a tank open road @ 17litres/100km & in the suburbs i average 25 litres/100km but i treat 5.7 how it should be treated "hard"

[emg]

If it makes you feel even betterer... I recently drove my car WOT each and every corner, straight line possible.. still managed about 300kms.. so it's not all bad mate! There's only so much it can drink. (usual bolt on mods)

[chillicatqld]

Yep, welcome to the REAL world.
I get 350 klms from 55 litres on the Gold Coast. (M6 ute VYII). Approx 15.5l/100klms.
I reckon all those other crew that reckon they get 11's - 12's in built up areas are pissin in the wind or driving like Mrs Daisy... :limpy: :limpy: :limpy:
Open road a different ball game.

[planetdavo]

I get about 18L/100 in stop start driving, and 10L/100 on the highway as an average.
Don't forget that the engine is a quite powerful "5.7 LITRES".
You can't have your cake and eat it too. Maybe a bit of extra homework would have been in order buddy......

[L30N]

In my VY SS i get high 16's to low 17's per 100kms driving it normally. With a heavy foot it could go up to 22L/100km. So it seems about right.

Sometimes it also depends on the petrol you put in your car. There are some servos out there with crapy fuel and sometimes that makes all the difference. Recently happened to me.

[Jake235]

yep my SS drinks about 16l/100km for city driving, mines a manual, so that helps a little, but i dont do much city driving anyway

I filled my car up on Sunday with BP Ultimate 98.. best economy to date since the edit. I've tried Vortech98 and Shell's V-Power Racing with not so good results.

What is the point of having cake if you can't eat it? I must drive like a :limpy: beause I average between 12-13 L/100km around the burbs.

[ti0350]

Our SS always hovers between 20 and 22l/100km thats because we do a lot of small trips and both of us live within 10 minutes of our jobs so our ave speed is always around 25km/h.. As soon as we go on longer trips it comes down to around 17.. I dont know about my missus but I give it a booting every chance I can...

[planetdavo]

Your 'burbs musn't require much stopping and starting then......:teach:
Like I said, it's a BIG engine, and you can't escape reality. Drive it like a Nanna in a Camry in the right hand lane, and I suppose you can get that figure, but is that "real world"? Hardly.
My average seems to match what others in similar driving conditions say they get.

[fordy68]

..chalk another one up the miss daisy drivers if you like, but i get 13s around town too... but really, I dont think i drive it too softly either. I guess it depends on what you think is soft or hard driving.

[planetdavo]

In my case, it includes a dozen 40km/h zones each morning in a 10km trip to work, three roundabouts, a dozen traffic lights, then back again without the 40km/h time zones, plus trips to the shops, and the regular (but not over the top) use of a "bit" of throttle.
It's using less than my old VR SS.

[ace185]

Open road driving I recently got 9.8l/100km with avg speed of 97km/h.
City driving can average 17l/100km with avg speed 30km/h. Both of those averages were done with moderate throttle and sometimes WOT. All this on a std VY SS A4 which would benefit from an edit and exhuast for a start !! At the end of the day they are what they are - and they are fun !!! They are also pretty good on gas considering - I used to have a Subaru Legacy GT twin turbo and that was about 20l/100km no matter how it was driven, but it was a rice burner !!:teach:

[BLKVYSS]

Just a Quick Add In.. I live in Albury... and my 6spd VY SS II gets about 14lt./100km.. On the freeway I've been down as low as 8.9lt/100km


And no, nothing is wrong with the car.. City driving I get 500km no sweat.. highway I get 800-900km..

Mind you I always use cruise control when doing to from work driving.. and I use the 'Holden Reccomended' Economy Gear Change Points..


But that is all JUST to from work driving :P

[AFAR]

Beats me how some people get 13l/100 in the city.
Ive tried and only managed 14.8 in the city (Just before peak hour).

I could probably do better by taking off in 3rd and hitting the gears every 1800RPM. But i didn't buy the car for economy.

[ssgirl2]

And no, nothing is wrong with the car.. City driving I get 500km no sweat.. highway I get 800-900km..

Wow!!!

I get excited if I get near 400km in the suburbs and 570km freeway holiday driving!

SS :)

[muzza]

Edited manual YII SV8, fuelled on BP Ultimate:

City average (around 42km/hr) best I've managed is 12.9L/100k (according to the tripmeter) thats with pretty moderate driving :limpy: and sticking with traffic. Normally around 13.5L/100k. On mainly eastern arterial roads and eastern freeway - NOT peak hour crawls from the CBD.

Change up just over 2000rpm, try to keep throttle in lean cruise, just chugging around - no fun but still a tame challenge of another sort.

Astounding country trip: Fill up in Doncaster, reset trip meter, head out via Heidelberg onto Western Ring Road, via Hume to Shepparton, wife+ 2 kids+ weekend bootfull: 8.6L/100k (according to trip meter). I've done 8.7 on the same trip before so it's no fluke.

Given the stonk available with just the twitch of the right foot I reckon the economy is brilliant. Wife's Magna 3.5 does round 16L/100k all the time with shopping trolley/kid run duties!

[BLACKWAGON]

Everyone talks about city driving........there are so many different routes thru every city which can have a huge difference on fuel.
The route from hell that we do everyday to work and back is 15km and takes around 45 mins. It all depends n your average speed.
After a tune, on our hell route we got 18-19.
After puttin 3.9s in we get around 16-17.
On the freeway it has been as low as 8.5 but generally 9-10 if the road is not dead flat with no headwind.
Its a manual and is great on the long trips like the rest of them I guess, this same route in our old vyv6 was 16.5 on average too in an auto so I am not complainin.

Apart from how heavy your foot is, another factor that has hardly been mentioned and is critical is your average speed when you get 18L/100km. If average speed is around 30kmh or lower I'm guessing 18 is to be expected (haven't had mine down that low to know for sure).

Also, how long are the trips you are doing? I have found with the LS1s I've had that they tend to really chew through juice when cold. When I do predominantly short (2 to 10km) trips my fuel consumption would sky rocket even though my average speed didn't change much from what it normally was around town.

FYI in my VZ SS A4 (edit/extractors/exhaust/3.46diff) I would get somewhere in the 14s around here at 40 - 45 kmh average speed and mid 9s on highway at around 100kmh average speed.

Ahh so the right hand lane is more fuel efficient is it? I'll have to try that. Would 10 k's under the limit help too? And would it help if I wore a cardigan?

I think I must drive :limpy:

Never ever given it WOT, and I do baby it.

The recommended gear changes - wow that would be no fun at all... feels like its labouring the car too much. My gear changes I thought were moderate and always are between 2500 & 3000. Guess thats why I use too much fuel... :cussing: :driving: :driving: But if you are limping around town in 6th gear at 80klm/hr (dont ask me how) I wouldnt be happy about saving a couple of litres - I would be more worried about the possible damage you are doing to the rest of your drivetrain. 6th gear for me is only for 100klm/hr +

But really who cares - its made for driving and I found that chugging around town really only saves sweet FA difference in Miss Daisy mode. What's $3 on a tank when they are so much fun to drive.

[zorro]

after thinking about this issue all night, I've come to the conclusion that if you have to whinge about poor fuel consumption you obviously have the wrong car. yes you can make it a bit better (edit, intake etc etc) but the saving of 2l/100klm is like driving 15mins to get fuel for 2c cheaper, the difference is minimal.

at the end of the day I know I drive a V8 and I know it drinks fuel. maybe some people don't realise this?

my missus lancer chews fuel too!!!!! she commutes through the city twice a day and the fuel consumption for a pissy 1.5l is s*&thouse

If fuel consuption is an issue maybe Holden should release another run of 4cyl Commos???

[chillicatqld]

right with ya there Zorak....

[ace078]

I think the only real city figures are sydney and melbourn where traffic is rooted.
Briz is much easier to drive around with less stop start, Hobart even easier, Albury?????? Can you even call it city driving?

Hwy on cruise i can get down to 8.5/9.0.
My misses has an 02 corola that wont go under 9.5 Hwy on premium!!!

[Crusty]

I filled my car up the other day and it told me 320km till empty, I think that was due to spirited driving after the last time I'd filled it, but I usually get around 400 out of a tank, however no matter what it always says I'm nearly empty but can only fit around 58-60l into the tank, one day I'm gonna get a jerry can and drive till it's empty to find out how much it really takes.

Don't do that Crusty. That extra fuel is in there to protect your fuel pump form overheating - and also you will get all the crap from the bottom of your tank...:idea:

My mechanic said it's all good just make sure I dont crank it over with no fuel in it, thats what frags the fuel pump. As for crap, thats what fuel filters are for :)

[nudenut]

Don't knock it, it's the best of both worlds, works for me every time. Not only do I save 2c/litre, but I also get a nice 30min drive in my SS. :idea:

I usually average about 14l/100km around town, but take "free-flowing" roads and avoid peak times when possible. Which is a damn sight easier in Perth than Sydney ...

Didnt MOTOR or WHEELS do this a while ago with a VZ Calais and from memory they got 700+km out of it - it was mostly HWY traveling tho. Il try and find the article tonight.

Can't say exact but it was around the 900klms, did it when the 6L calais came out to prove the point of not guzzling fuel. from memory didn't they drive through sydney cbd to make the story half interesting?

well said mate, couldnt agree more. For the record, i get about 13.5L per 100 kays on the hwy and about 25 L per 100 kays around the city.

There are VERY FEW mechanics that will honestly tell people it's safe to run the tank to almost empty constantly. The "muck" quite often nearly blocks the pickup strainer BEFORE the pump, causing the pump to overheat and fail. The main filter is AFTER the pump, and is there to protect the injection system at the engine.
Sounds like he wants you back real soon for a new pump.....:deal:

[QUOTE=BLKVYSS;842234]

Out of interest on this point I looked up again what the "Holden Recommended Gear Changes" where in my manual for best economy:

1st-2nd: 15klm/hr
2nd-3rd: 25
3rd-4th: 35
4th-5th: 50
5th-6th: 70..........!!

Can you actually tell me you (or anyone) drives their V8 like this?
Those gear changes would all be below 1500rpm!
That's just ludicrous - I put out more power than that on my freakin pushbike. :idea:
I actually (no idea why) tried these changes today in my car - the thing if it could, nearly pulled me over and slapped me in the face. It just hated it.

And Holden may have wondered why years ago they had so many cars back for engine rebuilds.... I say it cause they wrote absolute crap like this in the manual.

I say if you are have to drive a V8 like this to "save fuel" then you are missing the point!
Thats like giving ya missus half a stroke as you dont wanna wear her out!! :thumbsup:

[ssgirl2]

I say if you are have to drive a V8 like this to "save fuel" then you are missing the point!

That's ridiculous...along with getting nowhere fast and the embarrasment factor (that noise is shocking). If you used 6th gear at 70, she'd almost stall!!! :lol:

The things people say...:lmao:

[planetdavo]

Not everyone feels the need to hammer along in their V8's. Plenty own V8's for their easy power delivery and towing performance. They are the ones more likely to get the better figures. One should not take a forum full of petrol heads (and a few reckless idiots) as gospel.....
But, there's too many variables to really give an accurate average consumption figure.... Which probably means this thread will STILL be going on in 10 pages time!

[DKGandBH]

Hi all...

My VTII SS got an average of 12L/100km over 125,000
My VZ SS gets roughly 15L/100km

and the driving style is unchanged...

They both did/do better than 10L/100km cruising at 110 for long distances.

[FLI355]

My VY SS is dead stock and I get around 14L/100 around the city with a bit of driving on the freeway. On a trip to Canberra from Sydney I got an average of 8.6L/100k sitting on 120 with the cruise on. I don't drive mine easy at all but it's always got good economy. I 've never had a tank last under 420k's.

[FatBoy]

So far 400 to 450 kms from a tank seems normal in Sydney's sh!tty traffic...

Went for a run down to Sussex Inlet and back over a weekend and got down to the mid 12's per 100kms but that included some "spirited" driving through Kangaroo Valley on both trips... :)

8.6 at 120km/h!!!!!!
If you seriously do get that, you've done well, but I'd love to see that confirmed not using the cars trip computer.....
I know several people with either stock or just bolt on VY's (inc my Monaro), and none of them get that doing even "just" 100km/h with cruise on, the windows shut, and the paint polished for less wind resistance!

Bit of co*k and bull... do the bowser calculation - think you will find that's wrong....


I drove to the moon and halfway back last night - averaged 4.5l/100klms. Had a couple of fill ups via manned station in orbit. Mongrels didnt have premium 98 - lucky I packed some octane booster:yahoo:

[zorro]

^^^ so that was you at the end of the stratosphere scyting you could do the moon on 2 tanks!!!

[FLI355]

It sustains economy (on the trip computer) in the high 8s and low 9s for long distances. I went to the snow with 3 guys in the car and boot full of ski gear etc and even with the run up the hill and the fact i had numerous WOT instances whilst overtaking I still got economy (trip computer averaged for the whole trip) of 9.7L/100k on the way there and 9.5L/100 on the way back but I live 1 min drive from the freeway and my average speed for the whole trip there was 101 kp/h. I've got 700kays to the tank on long trips heaps of times and I filled up again with anywhere from 40 - 70 kays to empty. Taking 700 kays for 65 litres is 9.3L/100kays so I don't know what to say if someone can shed some light on how that is bullshit (not being a smartarse) i'm willing to listen.

I went to the snow with 3 guys in the car and boot full of ski gear etc and even with the run up the hill and the fact i had numerous WOT instances whilst overtaking I still got economy (trip computer averaged for the whole trip) of 9.7L/100k on the way there and 9.5L/100 on the way back but I live 1 min drive from the freeway and my average speed for the whole trip there was 101 kp/h. I've got 700kays to the tank on long trips heaps of times and I filled up again with anywhere from 40 - 70 kays to empty. Taking 700 kays for 65 litres is 9.3L/100kays so I don't know what to say if someone can shed some light on how that is bullshit (not being a smartarse) i'm willing to listen.

i think you will find the VY has a 75 litre tank... could be wrong.

75 ltrs is correct. New VE has 73 litre tank

[DKGandBH]

I used to get 800 + km's to go being displayed after a fill up after a long freeway trip in my VTII...

The VZ has never shown above 700

9.5-9.7L/100 is more believeable, but the point of it all was that the trip computer's can be anything up to 10% out. The only accurate way to calculate a trip economy is to start it at a full tank, record the km's, then when you refill it, fill it to full again and record the km's again, then divide the distance travelled by the litres used.
Quite simply though, it would be a massive struggle to find ANYONE else out there with a Gen3 manual that could legitimately get down to 8.6L/100 on a trip of any distance. Sure you could set the cruise at 100km/h, reset the trip comp, drive 20km's on a flat freeway without altering your speed, and claim you got 8L/100 (as the screen would show), but it's hardly "real world average".

The other side of this is that people are relying on the notoriously inaccurate fuel sender signal to tell the trip computer how much it's using. If it can't tell the gauge what level it's actually at half the time, how can it accurately tell it how much it's using either???!

[DKGandBH]

Just looked at my records...

The longest tank full was 757 km (which was 63.60 L @ 8.4 L/100km)
This was also the best economy I got.

Biggest fuel fill was 69.88 L

Average for 134331 Km was 12.99 L/100km

[SLugg]

mine averages 13.5 over 5 tanks of 98 round town and burbs

I got 8.6l/100km going from Narre Warren to Fisherman's Bend on the freeway in my tuned VZ SS A4 (extractors/exhaust) with 3.46 instead of 3.07 diff. Have always found trip computer to be quite accurate. Didn't use cruise control (it's not good for ultimate economy) and averaged just under 100kmh. Sat on 100kmh all the way except for a section of 80kmh roadworks.

Was blown away by that as had never got that low before so on way back reset it. Got 9.7/9.8 as was into a headwind. Going there had obviously had a tailwind. Had filled just before getting on the freeway and refilled at the end. Actual consumption was 9.3l/100km (just over 30mpg). Not bad for an A4 with lower diff than standard.

[greenLS1vy]

im doing 20.L/100km in my vy ss but thats city driving everyday, but as soon as i go on a highway drive it goes down to about 17L/100km remember thats an average, so if i was to keep driving highway all the time the average will just keep falling.

[Y55-7UT]

shite theres some thursty motors in here, my ss M6 uses 9.2l around town or i can drive soft with 8.6l, my ute went to newcastle and back with a full tank thats 75l covering 950kms averaged 8l with aircon on, or 7.8l with it off

[57VYU]

im happy that i get over 300km around town out of my SS ute but running a 232/234 cam and heads. have i bit of a heavy foot as well

on the highway still get around 500km out of a tank

[goose202]

There's some just plain terrible fuel figures here. You guys getting nearly 20L/100 must have a very heavy foot and/or a very low average speed.

On the highway at 110km/h my VX Calais will do < 10. Driving to work, ending in an average speed of about 40kmh it sits about 12-14L/100.
If it's used for nothing more than shops and back (ie engine never even warms up properly) its 15-18L/100.

Even when I take it through the Adelaide hills for a spirited drive it sits on about 15-16.

I don't know how you can keep a driver's license if you consistently drive in a way that gets you 20L/100.

Count me as an exception... my unedited CV8 averaged 8.5L/100 from Ballarat to Adelaide, I filled up on my way home at Tailem Bend. On the trip over I quite often sat "above the limit" because of all the trucks etc, and had a lot of overtaking too. It could have been that it was a brisk September night as the car felt incredible, and the air was chilly.

For the entire trip, including a stopover in Ararat and some blatting around there, Adelaide ity driving and a couple of stops the average came up to 9.3/100

My ex's VZ Alloytec used to get 7.3/100 on Ultimate on a trip.


As a point though, remember in city driving, your engine is burning fuel WHILE YOU ARE SITTING and your odometer ISN'T MOVING. the average fuel is only calculated on litres burnt and DISTANCE MOVED, so the calculation is pretty much useless in heavy traffic as you are only moving lets say 10KM, but are stopped, idling for 35 minutes of that, burning fuel. Also remember that in stop start, you are moving stationary mass all the time, this requires more fuel.

I recently changed my battery and what do you know im getting better fuel econemy i used to get 380-400ks a tank now im getting 450-480 a tank.
I THINK THATS REALLY WEIRD:confused:

Changing your battery would have effectively reset your PCM so it will be relearning, it is possible it will affect fuel economy slightly, depending if you have a tune or not and what bolt on mods you have done.

[Souljah]

Mine sits around the high 14's to mid 15's with an average speed around the 35-40kph mark. Most of my driving is only short, around town type of stuff. Not great for a bent 8.

[iloveholden]

Even my 6 hates the city stop start driving. Along the open road it goes way under 10L/100 and if i dont stomp my right foot it says around 11L/100 overall.

But had a couple work down claremont which is about a 2hr round trip for me in traffic and during these last two weeks i cant get any less than 12.1-12.3L/100.

I go from getting 650 a tank to like 500 and something which makes a difference is you are not used to it.

[myvyssute]

vy ute manual
used to get 16lts/100 but now ive got and otrcai mafless tune and 3.91 diff gears its gone to 19lts/100. i thought it got better?? i average abotu 45km/hr . my drive to and from work are on local streets so probly not any good and dont mind to give it a spirt every now and then but i have not changed my habits since the tune and diff gear thats y i thought it would have gotton better.

[1AFXWA1]

my VY II Berlina Wagon with aircond ON most of the time, which is a daily and work city car withall my tools etc in the cargo with a auto, std diff, gets 15.5-16.5/100 and 14.5-15/100 with air cond off.

[myvyssute]

yep have got a vy m6 ute. 3:91s exstractors exhaust otrcai and mafless tune. and getting about 18lts/100 city day to day. and thats changing at 2500-3000rpm. and just did a run up the coast and got 10.5lts/100 on the freeway. but i do think my fuel gauge is playing up. fuel light was on and saying 25km to empty but only took 53lts. it done that a couple of time now.

[VXCAL346]

My SV8 M6 with 3.9's with tune and OTR gets around 7.2-7.6L/100 on the freeway and around 12.5-13.5L/100 around the city and still runs 12.4@111mph

[Jman]

I'm averaging 12.6 in and around Canberra. Thats one of the good things about living here. 1 km from home to the Monaro Hwy, off the Hwy and 2km later into the carpark at work. Not much point in too much WOT in the mornings and afternoons, too much traffic. Weekends however......15-16 per 100km is my usual average.

Getting about 550 per tank which is around 2 weeks worth of driving the normal daily work commute.

The car is untouched so will be interesting what it will be like after I let Gentech play with it.

Happy with the economy and so is the minister for finance. But, like has been mentioned many times previously in this thread, fuel economy was NOT a consideration or a concern when purchasing the vehicle. Its just been a pleasant little bonus out of a 6ltr engine.:smilesandbanana:

[L-iam]

no offence but why buy a v8 of you are the least bit concerned about fuel economy. sure economy is a part of the car but imo no reason to sell it alone. if the car dosent make you enjoy driving it then piss it off for sure.

its fuel. it costs money. big deal.

[myvyssute]

My SV8 M6 with 3.9's with tune and OTR gets around 7.2-7.6L/100 on the freeway and around 12.5-13.5L/100 around the city and still runs 12.4@111mph
what sort of day to day driving you do? i do 20km each way to work average speed around 50kms. i was told to change gears at 2000-2500rpms to get down to 12lts/100kms. i was driving it a bit at 3000-4000 and was running at 22lts/100km. so i have todrive like a granny to get down to 12lts/100km. so it no fun to get better fuel. and i never got that low on the freeway it was about 10-12lts/100kms.

[VXCAL346]

mon-fri i do roughly 350kms a week to work and back which is half city streets half freeway. also do allot of cruising on weekends. Very rarely do i shift below 2500rpm, most of my shifting is between 3000-4000rpm. If i reset my fuel/trip meter on monday mornings by the end of friday my average speed is around 55-65kph and my average fuel usuage reads 11-12L/100k

[myvyssute]

thats better than wat i get. hope i can sort this problem out.
