Any regrets getting a 3.0i instead of a 4.8i?

I'd like to know why we have 87 89 and 92/93/94 here ... I want 91!

Then again, they say even going from 93 to 94 makes a difference in acceleration.

And just for kicks, check these out: http://www.dynotab.com/octanebooster.htm

I'd put 87 gas in my X any day over any of that octane boost crap

Outside North America the AKI is measured by the RON method, not the pump method (average of research method octane rating and motor method octane rating, two different tests). That higher rated fuel is not usually higher. 98 RON is very close to 92 pump octane. 95 RON is very close to 89 pump octane, what we call mid grade.

Don't try jet fuel, it is kerosene, much closer to diesel than to gasoline.

You may have meant aviation fuel, as it has a higher AKI than road fuel, but that is measured by a different test and isn't directly comparable.

yup.. it will burn right through your fuel lines...
