I know this can be controversial. This thread is open to any discussion relating to advantages/disadvantages of different octane/grade/brand gasolines.

I want to know if everybody follows the little "91 oktan" sticker with their porsche... I don't; I use 87.

I follow the 91 RON recommendation which is 87 AKI or regular in the US.

I run 98 RON in my car and have trimmed the FQS as required. Runs great.

I run 91 since the 944S has such high compression, i did run 87 in the winter here in my 924S and premium in the summer.

Run what your engine requires. Simple as that. Anything more and you're wasting money. Octane rating isn't a magical power booster.

If your engine is designed to run on 87, and runs happily on 87 ... use 87. (USA octane rating system)

Inside my gas cap there's a sticker that says to use 91... Maybe it means non US 91? I didn't know of different rating systems.

I use premium for the most part, if I'm short on cash I'll do Midgrade and lower the boost to stock 12 or if I have to use Regular I'll turn boost as low as possible, which I think is still like 5-7psi. Just to ensure I don't get stupid and boost with lower octane, I also keep my MBC in the engine bay.
