What Petrol do you use in yours ?

wow seems like you guys on the other side of the pond have many more choices. In New York the highest octane i can find is 93 if i could find 95 i bet it would run much smoother.

i have to run my car on 98 super unleaded i nomaly use BP

Isn't BP 97?



If youre buying 95 then it shouldn't matter where you buy it. All the petrol stations in the same area will probably get their petrol from the same refinery.

The usually saying is that where ever the fuel is purchised more from the fresher it is.
I used normal 95 octane from Tesco's and it was crap!
I used 95 from BP and it was better.
I used 95 from Shell and it was alot better.
I used Shell Optimax and i've never gone back since
I also tried 99 octane from Tesco's and it run like it had 95 from BP
These are all from the same area, within a couple of mile's from each other.

I also noticed, on Optimax, my injector's are alot quieter. That's not by coinsidence as i have tried and tested several time's!

TBH these test's are no good to man or beast as the car has to go through a tank of juice to tell the difference between each company.

I run my sport on a special kerosene/2 stroke mix with a splash of diesel.

optimax, on the IS / M3 and even my 316i there is hell of a difference in overall running and performance, fuel economy is better aswell!!!

I use whatevers cheapest, tried em all and couldn't tell any difference, I dont think our cars can take advantage of the higher octane.

The s14 evoII engine is the only one that needs 98 AFAIK
