It is the same grade of gasoline Premium-Ultimate-Super Excellent, whatever... it is 93 octane that's all should matter?
I've always been getting Sunoco, but lately got hooked on "7 ELEVEN" lower priced Premium... I do not notice any difference in driving performance in my E92 M3. However, when I used to fill up my 335i, I would definitely notice the difference in Engine Throttle Response depending on brand of gasoline...
Any thoughts on this?
Oh, thank heaven!
7 ELEVEN
