smoke out of exhaust when at WOT
My friend was behind me the other day and i did a nice little WOT, and he later told me that there was smoke or whatever coming out of my exhaust. Is this normal?? What the hell is it? Could it be 89 octane?
My car is a 99, with 37k on it. It shouldnt be doing this.
Let me know, thanks

DO NOT USE 89 OCTANE...YOU ARE WRECKING YOUR ENGINE
but just wait till your engine starts tearing up...then you will wish you spent the extra 5 cents a gallon.

It doesn't wreck your engine. Knock sensor changes the timing so that you don't get as much power or mileage. Knock sensors are there so that you can use 89 octane if necessary. 91 octane allows your engine to advance the timing to get slightly more power.

Use of an octane below 91 is NOT going to wreck your engine, clog your cats, or cause you to fail emissions. The ONLY thing it will do is reduce your performance and possibly fuel mileage.
