Hey guys
Was having a discussion with a mate about M cars and running different octanes on them and the effects..
Now, to me because they are high compression engines, they should run smoother, give more power and be more fuel efficient when running a higher octane, as the car would be able to run more advanced timing. (basically higher octane would be better in every way)
On the other hand, my friend gets better fuel consumption when running 93 in his e46 M3. Obviously the car is also less responsive too when running 93 as opposed to 95.
Has anyone else had this experience? Would love to hear your thoughts!
