Which Fuel is better?

[Ceffo]

I know this question can open a can of worms. But i have heard from a few

guys that optimax is bad then bp is another and also vortex is pretty good. Just wanna hear your view.

BTW also any other fuels that u have noticed.

I've tried both but found that my car pings a little when running Optimax. But it is a bit better on BP Ultimate. Vortex isn't 98 so you can't really compare it to the others.

I use BP most of the time as it is the closest to my house.

I think this subject has been discussed before and the result was 1-BP, 2-Mobile and 3-Optimax. Someone did some test on the three different fuel and found that BP had the least additive and cleaner etc.

I mainly pump BP Ultimate, as I found Optimax made my exhaust gas really smelly.

But either way with the petrol price been so high at the moment, I might have to start pumping water

[Ceffo]

Im pretty sure vortex is 98%. Most guys swear by it that it gives better grunt and no pinging.

[ghostflame]

Yeah i use vortex in my car. get it for about $1.04 per litre here. its 98 ron. for me i feel that i burn more wen using optimax. but had no troubles with vortex.

mobile synergy 8000 baby! 98 ron and none of that clean ur engine crap

[GTS_DUY]

caltex website says vortex is 95min

filled up first tank of bl ultimate today, everything seems good so far

[kris n loz]

i used to work for mobil and the synergy 8000 HAS GOT CLEANERS N SH** in it. never used it but good thread, might switch back to ultimate from optimax, now i think of it my zorst gas does stink heaps more than it used to on ultimate.

Poll fixed

I use both, optimax and BP ultimate. I have read about the optimax not being as good as its cracked up to be but for some reason I get noticably better fuel consumption on optimax.

And yes, now that you mention it I do notice a weird smell from the exhaust with the Shell brew.

[cul202]

I get slightly (but noticably) better economy on Ultimate.

i tried ultimate and optimax in both the N/A 2l pulsar and now the GTS-T and i get an extra 30 - 40 kms off it ??? i dont get it but its true

As a matter or interest, Octane Numbers are not a percentage. They are a rating that can increase past 100. It is determined by using both the RON and MON of the fuel and calculating a final octane number.

Vortex is definitely NOT 98 octane and it makes my PFC knock sensor go off its tits.

Of all the fuels i've used, Evolution 98 is the best but the servo that sold it locally just stopped carrying it.

We have tried all of the above. Every time we have had it tuned at Croydons Jim has complained "what fuel have u got in this car!?". The last time we had it tuned we used Syn 8000, it was the first time Jim felt good/smiled about our car, because he could actually see/get some good results. We also added oct.booster.

Even though we live 45 min from the nearest servo that sells it, it seems to be worth the drive.

I only use Ultimate in the rotor. Optimax is a little too dense for mycar, Ultimate seems to yeild the most reasonable results, and its tuned for it.

Different story for Piston engines though I guess, as to what fuel suits best...

i've been sampling it on and off,

will chuck it in for the dyno day and see what happens between that and ultimate

[T0nyGTSt]

Bp98 and Synergy thanks.

I only use Optimax if I have some 4c off shopper dockets.

Vortex at a pinch.

WA fuel

with our boutique fuel regulations its refined better here. Over here we have

BP Ultimate98 98 RON the best i've used in WA

Caltex Vortex 96 RON with an injector cleaner. Crap ping ping ping ping all the way

Shell Premium unleaded 96 RON quite good for a 96, very good with the stock ecu pings with the powerfc. (Due to the boutique regulations we can't get Optimax as its refined in the Eastern states. Last time I checked)

Mobil we don't get.

Gull Premium unleaded. 98 RON bought from bp then different addatives added. Haven't tried it.

[2BNVS]

i mainly use either bp ultimate and optimax, both are really great, when tuning though my mechanic said optimax is a bit harder to tune so make sure its all fresh, when bp is accesible ill get it no doubt but mobil syn, is no where in our area...

vortex is shithouse, used that and car ran crap, even in my parents magna vrx fuel consumption was shocking compared to optimax...

ben...

[Busky2k]

Ultimate for sure. Optimax literally stinks thanks to its high sulpur content. No good for my nose or the engine for that matter..
