Thought I'd put this one up, because I havent been here long and I'm curious to see what E30 drivers feed their Bimmers. These are all Canadian numbers, don't know if the grade numbers are different in the US of A.

For the record, I only discovered the existance of Super Premium this morning at our local Chevron. 94 octane? Sounded like the ticket. So I bought a tank, and yahoo, the car runs amazing. Especially when you step on it. Smooth as a turbine. It was a 1.08 a litre, which is painful, but ah well. Regular will get there eventually.

So you know how I voted.

Gas prices do suck. $1.08 for a litre of gasoline is highway robbery, even if it IS 94 octane. Kowalski, why go from Chevron to Shell and then back to Chevron? Chevron is the only gas I put in the 325e, and if you run it awhile with that gas, the ICV flutter and dead-cold power surges go away. Switch back to other gas, and the problems return.

Chevron with Techron 94. Rocket fuel in disguise.

after 5,000 the deposits build up and because the different companies have diff gases they eat away the other deposits after 5000 theres decent build up switch to shell for a grand to remove it all and then back to chevron. and yes i love chevron however i have problems with either gas i think its my plat. plugs im going to change them when i get off my ass, tomorrow im doing my tensioner and exhaust gaskets so maybe ill pick up some copper plugs

Admittedly, the only reason I'm on here is because I more or less inherited an 84 318i this week... so I haven't had to put gas in it yet... but will most likely put 87 in it when I do. Anybody know what our cars are actually designed to run? If they're timed for 87 then running it on 94 would just leave you with unburned fuel and possibly additional buildup in your engine. The higher the octane the slower the fuel burns.

1984 318i 5-spd that's not currently registered... project car.

1998 Subaru Legacy Sedan

1996 Nissan Maxima is the girlfriend's car that was glad to meet somebody who knew what &quot;routine maintenance&quot; was.

I use super premium in my 1990 325i. If I try to use anything else the car runs like crap.

if an e30 runs better with high octane fuel on a stock engine, you have excessive carbon deposits in your engine(perhaps among other things). 87 is the only thing you should have to use, and if its well maintained, with a 8.8 c/r (just an example, as thats what the 325i has) you wouldn't notice an increase in hp.

keep buying that premium if you want, but its pissed money away. and whoever mentioned it that 91/94 burns slower is right, it can negatively effect a low c/r engine.
