what fuel do you use?

[wfracing]

i was just wondering what fuel everybody is using in the ls1?

shell optimax
bp ultimate
caltex vortex

[HSVDKB]

LS2 BP Ultimate

[whitessute]

shell optimax with the 4c coles dockets

[wfracing]

i have heard bad things about all the different types of fuel but are using the bp ultimate and the ute seems to like it, i was just wondering what everyone uses.

[throttlehappy]

i use mobil premium (95)
nothing but

[MTC]

I use BP ultimate 98 in both our LS1's

[Peter B - CV8]

Used to use BP Ultimate - but got pissed off with BP a few months ago with their constant lack of supply. Have since been using Caltex Vortex 98 & very happy.

[Drewie]

Been using the BP Ultimate 98, but if prices keep climbing will probably drop back to the 95. Stock tune so it even runs fine on 91.
For what it is worth I had a rebuild about 2 years ago and the car had been run on Mobil 8000 from new, the Holden dealer commented that there was heaps of carbon build up in the heads and in the ring lands, it was not using oil the rebuild was for noise so we put the carbon down to lots of city low speed driving, I thought it would have been spotless using the 98 from new.
As the idea of the 8000 and other 98 RON fuels was to supposedly keep the motor clean, not the case in this instance.

You'll find that's more about the state of tune and the way the engine is driven rather than the fuel used. ;)

[lowhsv]

caltex vortech in the LS2 for me

[HacketR8]

Caltex Vortex 98 for me

[scottb231182]

Optimax or Optimax Extreme for me. (VZ SSZ Ute)

[JT]

BP Ultimate

[Goggles]

in my VYII SS, I used Caltex 95 - only had that fuel card

in my VZ SS, I can use either Optimax or Vortex 98.....depends on which servo I am closest to when I need to fill up.

[Azza]

For the NSW guy's here's a little info for you the next time you fill up.
Shell
BP
Mobil

It all comes from the same refinery- SHELL OIL Clyde.
Don't believe me? Take a drive down there one day to Durham Street where you'll see all the tankers lined up in the Shell refinery yard waiting to be filled with Shell products.

There are only two oil refineries in Sydney, Shell at Clyde and Caltex at Kurnell.
Take your pick :)

Lately I am shopping around a little.

BP Ultimate,
Mobil Syn 8000
Caltex Vortex 98.

All good but I got slight knock on Vortex about 2 weeks ago but has been fairly good most of the time since. BP and 8000 seem the best and perform good for me but lately the 4c discounts are coming in useful and I think twice before doing a WOT without reason to do so!
:p

[wally01]

Here at the bottom of the country i have only ever heard of the name ..

Any how i only have a 6 and i run premium stick that regular stuff runs better and goe's further ,did i spell that right Hic ..

[chev]

BP Ultimate.Would like to give Vortex 98 a go but I don't think it's in Melb yet?

The stock tune is quite rich - probably the main reason for your carbon build up.

[LJC 57L]

My car pinged on sloptimax had a re tune at Sams and now it runs on Bp Ultimate the car doesnt ping and it feels better 2 drive.

[Y2kGoofball]

hmm interesting azza, i know its at clyde because you can see the stuff burning out of the stick on a nice cold winters morning just as you get passed church street offramp on the M4

Ok dont have an LS1 (or 2) yet, so I'm trying to push my little old crapotech 3.8L V6 into a super duper stock standard performance machine lmao!

I ran Optimax 98 for a while, then switched to the 100 for a few tanks and noticed the difference, with 98/100 it definately gets more out of a tank full and I'm talking stop start peak hour driving here, but I found with the 100 the engine didnt seem to rumble around in the bay as much, if youve ever driven a pre alloytech VZ then you'll know what I'm on about!

The past few tanks have been BP Ultimate after someone suggested it, although I havent really noticed a difference.

After reading comments like Peters I think I might go back to standard 91, that is what its built for, and run the 98 or 100 every now and again. Its a difficult subject, everyones got different opinions. Ask a mechanic and he'll say its worthless because of this and that and this and that, yet his mate on the otherside of the workshop will tell you completely different.

[swingtan]

Hi Guys,
Have only just started with the VZ-SS but with my VX-SS I used Shell ULP for a year before going to Optimax for the remaining 4 years. I have full mileage figures for the 5 years, if any one is interested I can supply some graphs shown MPG, Lt/100Km and the all important cents / KM.

The I've posted this elsewhere but I tended to find that every time fuel prices went up, economy went down. Of course this is just one mans experience, but you don't often get a 5 year fuel trial of just one brand of fuel. Oh, and if you're interested in knowing why I only use Shell fuel, think Novate Lease with a fuel card.

Drewie - Your car should run cleaner on 98, when I removed the fuel filter after running all sorts of fuel, it was nearly caked up with crap on the inside, plus I had carbon buildup on the piston crown.

After that experience, I religiously use premium 98, mainly BP but Shell on occasion.

[MJS57L]

I use BP ultimate.:argue:

I think in my case it was too much low rev, low speed, short trip, traffic work
that may have contributed to the carbon build up, I try and give it a bit of a rev when I can now, and try get a regular highway run in a bit more frequent.

[Wonky]

Boost 98 (United). Much cheaper than Ultimate or Opticrap (typically only about 3c more than standard ULP) and according to some threads on here about 6 months back gives more power than Ultimate or Vortex 98 etc.

In my experience that seems to be the case too. My previous VZ SS made 210.6 rwkw with exhaust after tune (on a known conservative dyno) running Ultimate. This one with identical setup made almost 214 on Boost 98.

It could be due to differences between cars but based on results Street Tuna wrote about I think it's more likely due to Boost 98. I also find I get almost identical mileage on Boost 98, something some people have commented on negatively for Boost 98, probably because mine is specifically tuned for it.

[chevypower]

E10 from United (95 octane) - for my LS1 cheapest fuel around, car runs beautifully on it, i average 12.5L per 100km (mostly urban driving), and can still out-accelerate most cars out there, drives nicely - why would i want to pay more? I honestly doubt my car would improve with more expensive fuel.

[hogs]

Evening,

I specifically asked the question in relation to Boost 98 to the GMH spokesman on the Forum and was told, " That GMH has no issues with E10 petrol".

Since then I have run United Boost 98 mostly and find that the throttle response and general performance to be equal if not better than either "Opticrap" or the very much OVERPRICED BP Ultimate.

Cheers,

Hogs.

PS I have been lead to believe that Boost will tend to lean out your AFR's but given that on my most recent Dyno run mine have been rich I do not have problems with this.
Any tuners who would like to comment, I would appreciate the feedback.

[stickyfingaz]

i like to use shell optimax or that new one thats 100% octane but i have been told that i should only be useing regulr unleded as this is what the car is tuned for and i wont get that much better fuel economy?

[RED R8]

Mine seems to preferr catex vortex I recently put a bottle (red) of inject tech fuel system cleaner and have noticed a improvement in fuel economy and smoothness.

[VS L67]

No Ls1 but i've feed the L67 all the above and it seems to run smoother and pull harder at freeway overtaking speeds with BP Ultimate,

[Wonky]

I'm with you Hogs. Must be something to do with being 51! :D

[vyssls1]

i tryed several different premium unleaded fuels, when racing carts and also got them tested on many occasions by the fuel testing officials, and there results back then were caltex 98 premo unleaded.

so ive always religously ran caltex. and just a tip for the sa people, the fuel testing officials did a test years ago, and found caltex bolivar had the best premium unleaded around adelaide, due to the high octane reading, and petrol tankers constantly filing there tanks.

and were always filled every sunday morning early hours.

i also did some fuel testing with another workshop here in adelaide, and results were that saff premium unleaded gave up to 50km a tank more than any other fuel on the market.

A little off topic, but was talking to the guy that cleaned the injectors
on our Forester about bottles of injector cleaner. His response to
these was a flat quote Do not use them Unquote, they will cause
more problems down the track he reckoned. He basically said they
are too aggressive and that they wash all the scale and shit off the
fuel lines and push it further on down the fuel system towards the
injectors. Also said you will get an initial improvement from them,
but then things will start to go to shit and eventually end up
stuffing the injectors. I remember years ago, putting a bottle
of cleaner in my old 318 Charger and my father inlaw who is a mechanic
by trade rolling his eyes and informing me how bad the shit was for
my car. Anyway, sorry for going off topic but thought I would share
these pearls of wisdom.

And Holden drop the stuff in when they service cars. They did it on my last service anyhow.:eek:

No problem though fortunately.

[saaz]

I have only got the car (WL 5.7) and run 91 octane in it so far (3000kms). The fuel usage seems to be consistent, so am going to try 95 octane to see if it makes a difference in feel and running costs overall. Having to keep records for the lease has some benefits! The next 2000kms will take a month so be back shortly...

bp ultimate

[dcholden]

I always used to use Shell Optimax 98 Octane in my previous WH Supercharged Statesman. My missus also used this in her Merc from new, and then it started running rough all of a sudden and so we took it to Mercedes to be looked at, and the spark plugs were fouled. They asked what sort of petrol she was using and so she told them. They then said to her to only buy Optimax from big service stations, apparently if it's been sitting around for a bit it can actually foul your plugs instead of clean them as it's supposed to. I use the Caltex Premium (95 octaine) Vortex I think it is in mine, and I have no problems. A couple of years ago I owned a V8 fairlane and It didn't like mobil fuel, mad it run rough as hell. So I have never gone back to try again, even the servo is only 2 mins from my house.

[Davothegreat]

I was using BP ultimate in my SS for a while but decided to try Caltex 98 this last tank and fuel economy has improved by 2L/100km (19L down to 17L in heavy city traffic). Car idles the same, pulls just as hard, no vibration etc. So I'm going to try a few more tanks of Caltex 98 and if it continues to stay at 17L then I'll be sticking with it, especially since it allows me to use my Woolies dockets to make it cheaper. Incidently, when the tune was stock, it was the other way round, BP gave better economy than Caltex.

yeah same here. Put the vortex98 in with the Red Techron 5000 cleaner and it runs fairly nice. for a FRAUD. :yup:

[Oztrack Tuning]

My new best time 11.619 with baby cam was set on Mobil 8000 with no additives at all. Taking 28.5 deg of timing with 10.7:1 compression. It behaves just the same on Vortex 98 - havent tried BP for a while and its been years since i have used Optimax.

I did try Boost 98 - but it didnt help it take more timing.
