Running the VE SS on 91 ron fuel

[prodrive]

Hi guys - planning to get a VE SS very soon. The only problem is my work will be paying for fuel and operating costs. They will only approve 91 RON fuel to be used in the VE SS (because the manufacturer says it can run on 91 RON).

The Holden dealer where I tested the car said it is much better running the vehicle on premium.

My question is - those of you who have tried both premium and standard 91 ron unleaded in your VE SS, how is it? Is it noticeably down on power?

Thanks!

[swingtan]

The car will "run" but not to it's full potential. there is a noticeable drop in power once the management system pulls the advance back to compensate for the lower octane fuel. If you are doing a salary sacrifice deal, you usually can get an adjustment made to allow premium fuels. I've done this with my VZ and would push for it on any car. The car simply runs better / smoother on premium fuel and I'll pay the extra to use it.

[Ridin-High]

Ask your workplace if you can put in 10c per Litre to use 98ron as you know that it will run much better and delivery better fuel eco

[Devil CV8]

I know with the telstra operating lease vehicles that 91 ron is all that is approved and it impossible to get around it as anything other than 91 is rejected when the card is used. The only half decent car that allows even 95 ron is the xr6t.

Saw this interesting article on TV today

Not too sur eif its located anywhere around here but i will post up a thread to it....

[Marco]

I've run mine almost totally on 91 RON since I got it and noticed no ill effects. When I did experiment with 98 RON, I noticed no difference in the feel of the car and not enough difference in fuel economy to make it worth the extra expense.

Whether this is good for my engine in the long term is another matter, but I figure that if 91 RON was actually bad for the engine, Holden wouldn't tell you that it's okay to use it.

I believe you need to run about 3 tanks of better fuel through before the ECU makes full use of it. That's what people who have gone up to things like Shell V-Power racing have found. The engine management system seems quick to protect itself against bad or low octane fuel but much slower to commit to fully taking advantage of better fuel.

[Marco]

Ah, okay. I'll have to try the experiment longer term then and see how I go.

[BadMac]

I have run my R8 on a mixture, 91, 95 and 98.

I have tracked my fuel usage since brand new (now 16,000km) and can offer the following based on my Excel Spreadsheet and Seat of Pants.

Each fuel type has had at least 5 fills (fuel warning each time, stop at first click). My driving is pretty repeatable and involves 300km per day of driving 4 days per week (rest round town). The driving is mixed and my graph shows some heavy foot days and some cruise control days (I also track how I drove it), but in the main the average is pretty consistent.

91, drives well, no pinging, etc. Feels a little empty in terms of performance compared to the best (noticable when pushing hard during passing). Still good performance, compared to any other car iv'e owned.

95, better than 91, don't notice the power missing except during very hard acceleration events.

98, definately better in terms of performance, feels 0.5 sec faster to 100 than 91 (but who knows, could be wishful thinking).

It does seem to take the car a few hundred kays to get the previous fuel out of its system (just my observation).

I am presently doing an experiment, whereby I have just done 2000KM with only 91, next fill will swap to 95 for 2000KM, then 98.

octane----KM-----l/100km---cost/100km
98------3867.45---12.63------$20.15
95------7199.03---13.11------$20.03
91------1959.78---13.56------$20.64

98 IS more economical and in price terms its very close.

Summary. Theres nothing wrong with 91 for normal everyday use. 98 is better but you will only notice when pushing hard.

Did someone say Telstra? So it looks like I will be stuck with 91 ron then. :bawl:

[AussieTone]

I know of a bloke who had a fuel card that would not allow 98 but after checking some of the BP Service Stations around the area found that some had the facility to put the amounts into the computer by hand :eyes:. As a result he always used 98 but the receipt showed it was in fact standard unleaded. Total dollar amount was the same just different liters between what the pump showed and what the docked showed.

Trick was to make sure you didn’t fill up an empty tank as the receipt would show you used more fuel than the car would hold. Think he said it had to be a franchised station like the BP 7/11

Think if we ever caught his work and the police call this something else :bawl:

[milkojnr]

I really found the only fuel with any real noticable difference in my SS-V was the shell V-Racing. It was a completely different car. Alot more powerful and I LOVED it!!!!

i felt I was only really using the engine was when I was using the V-Power Racing.

By the way I in no way work for any Fuel company or Fuel station.

[Tyre biter]

I am with Marco - I can't pick the difference.

Very interesting Results

Here is an overlay of an high octane to low octane spark map, as you can see when the pcm reverts to this map it can take up to 12 degrees out , and this eqautes to 10 to 60 rwhp loss

So in simple terms you need more throttle ie: more fuel to make the same hp
The pcm is very quick to react to knock so you wont even hear it and it will stay with this map until no more knock is present

low octane : bad
high octane : good

[Oztrack Tuning]

91 will be bad for the engine. The VEs have persistent low level knock stock at around 1600rpm and thats even on 98. A car with that much compression should never run on 91. Its terrible stuff - when you see tuning logs with standard cars on 91 you will see good reason for never using the fuel. What people save on fuel they will spend even more on new engines, probably just thinking it was bad luck - their luck will run out most likely a little after the warranty runs out.

Even though the dual timing table acts to adjust to a better level of timing for the 91 fuel, the only thing that actually keeps it near the lower table is knock that is detected by the knock sensors. No knock under load the car learns to the maximum timing , persistent knock and it resides closer to the bottom depending on how persistent the knock is. If there is knock anywhere eg 1600rpm then the whole timing table scalar resides closer to the bottom table s- so you lose timing advance everywhere.

[Danv8]

91 octane ?
*shudder*

Showing love for your car is giving it the good stuff not 91 octane.

If you look at my figures, you will see you DO NOT save money on 91. The economy versus price is best at 95, then 98 (we don't get 100 in NZ), with 91 a distant third. Saying again. YOU DO NOT SAVE MONEY USING 91. Not only is it bad for your engine, but it costs you more per KM travelled!!!

Does anybody know if the Pre VE's (ie VT/VX) LS1's are the same story, ie better performance/economy from higher octane (out of the box), or is that only acheived with a tune?

[Oztrack Tuning]

The HSV's definitely would gain on 98 (too much advance in manyu areas of their top table). The 220-225 tunes probably would gain very little (they dont have much advance at all). But they all behave badly on 91 mostly at low rpm high load.

[old holden V8]

I hear what you guys are saying Steve.....BUT for some of us 98 is at least a 1/2 hour drive (or more) away.

ie. 91/95 available everywhere, 98 is very much a pain to get.

Do you recommend 95 in that case?

The other thing to take into account is long term maintenance regarding fuel filters and dirty injestors. Running good fuel will keep everything nice and clean generally. I see the additives and sometimes deliver tanker loads of it to fuel terminals it's like bloody treacle. My old VQ statie ran for 9 years without any injector serviceing and only 1 set of plugs, it ran as good the day we sold it as when we first got it. Nothing but 95 octane fuel in it.

95 is fine. 98 is better. 91 is terrible.

[Devil CV8]

same as me when I order the SS-V next month. Pity I'll overlap the lease cars by 4 months.... but if I wait the cost will blow out too much.

[Rad Kane]

Reading an article on the Shell site, it seems very little advantage in running it in the Shell V against the 95. Except with an addition of some 'lubricants'.

I am going to run few tankfuls on the 95 and see if it is detrimental in any way.

[prodrive]

same as me when I order the SS-V next month. Pity I'll overlap the lease cars by 4 months.... but if I wait the cost will blow out too much.

Why is that - is the salary sacrifice amount on that model going up?

[Devil CV8]

Why is that - is the salary sacrifice amount on that model going up?the amount can change each month. at present the ssv is 23k per year and has been stable for a couple of months after dropping from 25k. Once you sign up, the amount doesn't change for the duration of the lease, so please pity all those paying 25k and more for the ssv.

When I ordered my sv6 in november 2005 (delivered feb 2006) the lease cost had risen by 1k from october.
basically it's luck of the draw.

[igniton]

hi performance car you wont, but cant use the best octane for it ?hmmm
simple just get a datsun 180b and run it on anything :yahoo:

I don't think you quite follow the proposition here.

If I use 91 ron my work pays for ALL the fuel I use. If I use premium I pay for it. Now what would you do? You would put in 91 RON guaranteed.

don't worry. not many people can grasp the idea of an operating lease. a few minor issues such as no tint, a limited vehicle selection (still get ss, ssv, calais, xr8 and xr6t tho) no pulp (except for turbo) no 98 at all, but the only thing stopping you driving around australia 100 times is yourself. ALL fuel, tyres, services, insurance, repairs, fbt is taken care of.

True - hey DevilCV8 I wanted to PM you but I don't have privileges yet. I am going to order the VE SS before 1 June. I fear a price rise due to increases in petrol prices. Like you said though it is luck of the draw.

The base model SS manual is $20,500. Hopefully it will not go down in price on 1 June! Regards :wave: What do you think?

[Carrots]

Perhaps another option would be to fork out for some high octane booster for it every 2nd tank or something along these lines to compensate....is it just going to be a car you keep for the duration of the lease (if not shorter) then trade up for a newie etc? If thats the case - who cares what you run it on as long as it runs right? Cept the bugga who buys it 2nd hand might care a bit :D

[Devil CV8]

The base model SS manual is $20,500. Hopefully it will not go down in price on 1 June! Regards :wave: What do you think?
It must be the April pricelist I have at the moment as the SS is 21k and the ssv is 23k.
sept 06. SS 23k, ssv 25300
dec 06. ss 23k, ssv 25k
Apr07 ss 21k ssv 23k

From what you're saying the may pricelist has the ss at 20500 a saving of 500.

It is a lottery wether it goes down or up or stays the same in june. May I suggest you make the decision based on what you want and not check the pricelist or else you may cry.

[TigerVXSS]

It depends if you're a punter. A mate (yes I'm Telstra as well) ordered a car and the price fell by $1000. He canceled ($200 fee) and reordered, saving himself $800 pretax per year. It's not much, but still...

I was keeping historical price lists, but lost the 2000-2005 ones in a fcckup. From what I remember if doesn't seem to follow any trend, up $300, down $200 etc..

My Adventra comes up in November so I'm ordering in June/July. The increase to the SS-V that I really want is really steep. It's worse that the difference in price to the XR6 Turbo is so large - justifying the SS-V is that much harder (to the wife).

Not considering a (very expensive) list SAAB are you? Fleet are truly jokers...

At least all the running costs are covered. My previous Fairlane G220 used an average 22l/100km. The SS before that used (cough) 9 tires. My driving style is not conducive to actually paying the bills....

It's worse that the difference in price to the XR6 Turbo is so large - justifying the SS-V is that much harder (to the wife). If I'd stayed in my old job I would have definately taken the turbo as it would be a $4000 (approx) rise per year over what I pay on the sv6. With the new job I can afford the SSV and order in June for a late october delivery and still keep the sv6 untill feb next year and not be worse off financially than I am now. Just need to decide if I get the ignition or even the morpheus SSV.

Some great info so far in this thread, but it would be great to get back to the question of regular or premium unleaded fuel & what is the noticeable power difference, etc, rather than leases, etc.
I am pretty interested in the facts re the fuel question & there is some valuable info here for all to consider for :1peek:their choice what to run their own car on.

[SPUD71]

I have just started running Higher Octane fuels in my SS. I've just clocked over 18,500 kms, most of that on 91 RON. I tried BP Ultimate, and Shell V-Power. I didn't notice huge differences, but one thing I have noticed is the lack of "Jerking" when I sink the foot before the cars warmed up to normal operating temp. That was all until this morning when I thought I might try Shell V-Power Racing. Hooooooooooooly Crap!!!!!!!:eyes: Its as if someone has thrown a few more horses under the bonnet while i was in paying for the fuel. :bow:Huge difference, smoother driving, and a more noticeable throb while idling at the lights. I can't comment on economy yet, but basic common sense says if i have to use less throttle to get more horses, I'm gonna use less juice. The only downside is the cost at the pump. Todays price for 91 RON ULP in Melbourne was 1.30. V-Power Racing was 1.47/Litre, but I do have the unfair advantage of having a lease through SMB, using a Motorpass Fuel Card. They don't give a toss what you fill up on, and I don't pay GST. If the motor is running more like it was designed to, it only has to be a good thing.:vpo:

I totally agree 110%.

I have been using it for about 6 weeks the only problem is you cant go back to normal 91 as you have now seen the power of a fully aimed and operational battlestation. I tried 91 again and it drove me crazy for the whole tank until I could get the V-racing again.

Only problem is that not all Shell Station have V-Racing...

[mmjlw]

Sounds good I have just bought a SS-V and have just done around 2800kms I might try the V-Power Racing fuel and see how it goes I travel long distances on the freeway and should get better fuel ecomony with it.

[Nawdy]

Just coming up to 25,000km's in my VE SS, and have run it on nothing else but BP Ultimate, with the exception of filling up along the Newell Hwy where 98 wasn't readily available. Put 91 in it, it felt like a slug in comparison and fuel economy suffered.

Throttle response was down, shifts seemed slower - this is all SOTP stuff, but my other half noticed it as well. It's enough to convince us to stick with 98. My VX SS was the same - anything but Ultimate affected the performance and economy.

We've also driven other VE SS's that have run on 91 and 95, and they felt exactly the same - relatively slow and unresponsive.

It doesn't make sense to me - spend all that money on a performance orientated vehicle, and then put the cheapest/nastiest fuel in it that inhibits performance; it's the same thing as putting the cheapest/crappiest tyres on a performance car - it defeats the purpose....:weirdo:

[saaz]

I am on the second year of a lease WL 5.7 (so the car is standard). I have tried 91, 95 and 98, along with ethanol blend versions. The higher octane fuels don't make any noticeable difference in fuel economy or performance. I usually stick to Caltex as I get an extra 2.2 cpl discount. As I am getting 11.5lt/100km fuel average the cost of higher octane does not worry me much, but I prefer to spend the money on things I want rather than hand it over to petrol companies. E10 blends are now consistently available in Canberra so I am trying them to see if the 3cpl lower price isn't lost in the lower fuel economy.

I get the feeling quite a few of the lads on this forum are Telstra. Count me in as well. Just ordered a Calais V 6.0 litre (due October and can't wait), $500 cheaper than last month.(April). Still dear compared to the 18k i have been paying for the Monaro, which by the way runs on PULP allowed on the fuel card.

[Marco]

Allright, you guys have convinced me. Starting next tank I'm going to try 98 for a few tanks and we'll see how that goes. I've been tracking my fuel economy on a spreadsheet since the second tank of fuel I put in the car, so the difference should be evident. I'll report back and let you know :)

[katlad]

I used premium 95 in my SSV from day 1 until a couple of months ago then started to use BP Ultimate, I dunno about fuel economy as I havent been recording it or anything like that but the throttle response & extra grunt were noticeable, I will be the 1st to admit that judging stuff by seat of your pants is very difficult but I could definately notice the improvement, no going back to 95 or heaven forbid 91:spew:

Just remember after you have flushed out the 91 rubbish (as said will probably take a few tanks before computer adjusts to the new fuel), having said that odds are you'll be giving the beast some stick loving the new power so i wouldn't base it on the the first few tanks either. It was like when i put on my new exhausts i said to the missus "it's to be more economical on fuel" well i can't stop playin with the revs and it's bloody well costin me more and everytime i get a new tune or bolt on more good stuff i drive it harder and faster and well .... picture painted! :yahoo::driving:

As smokiebbear said, give it a few tanks and you'll notice the difference. If you want to really see the difference, go back to what you were using after a few tanks :confused:

You'll be converted to 98 in no time!!

It's quite simple really Marco, you car has an upper and lower timing table. If you run 98 fuel in it, it will run on or close to the upper table giving you more power.

There was an error on the June list that made it financially better to take an SSV over an SS, that has now been rectified but the change in value means anyone who signed up even in May will shed a tear or 2 when they see june's lease costs. If you signed up a few months back thoughts of self harm may enter the head.

[Pacific77]

BadMac, you seem to have done a comprehensive fuel study, I was planning to do something similar. Can you say if you kept track of which fuel supplier you used and if there was any difference. I understand some use E5 (5% ethanol, shell I think) and other E10.

There was an error on the June list that made it financially better to take an SSV over an SS, that has now been rectified but the change in value means anyone who signed up even in May will shed a tear or 2 when they see june's lease costs. If you signed up a few months back thoughts of self harm may enter the head.

Wish I was back at Telstra enjoying my fleet car .. :(
