engine will pull timing to compensate, which will drop power and fuel economy levels.Question.......... your out sportin' around in your fancy new car and you find yourself low on fuel, small town usa only has regular gas. What are the repercussions of running regular?
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
> 323i, 328i/xi: 87
> 335i: 89.
If you use gasoline with this minimum AKI Rating,
the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life
I know. I was replying to Orient's comment. If 87 is all you got, so be it.The OP said "small town usa only has regular gas."
My suggestion, drive someone else's car to hick town that takes 87. :thumbup:
Tell your boss that New Hampshire has 93 octane in any brand you want. Look around a little and you can find 94! Hafners has 107, but it's leaded. Made my 66'Stang go like hell with the timing set at a base of 24 degrees and a total advance of 36.I know. I was replying to Orient's comment. If 87 is all you got, so be it.
My boss fills up his brand new G37 with 89, saying that California has higher octane than the rest of the states.
I could not convince the guy that $100 he saves in a year, is hardly worth it...
Damn. Spent all that time getting an SM in Chemical Engineering from MIT, only to finally learn from a gearhead in the office that all that stuff they taught me was wrong.A guy in my office has an '04 530i and says he fills it up regularly with regular. Shocking to some but this guy is a gearhead and seems to more than know his stuff. The actual difference between the octanes he says, "is all in your head".
