Why have you used 89 in your other vehicles? Usually doing so equates to wasted money. Some engines with high compression or highly advanced timing may require higher octane but most typical engines don't gain a thing.O'Reily said:Do you guys use the recommended 87 octane gas or higher? I have always used 89 in my other vehicles, and I was curious what effect it would have, good or bad.
runs smoother I guess and there seems to be alot of people that have problems with the engine knocking. A higher octane gas might cure the knocking problem.funny, I was just going to start a forum like this. Venom35, what do you mean by better? Faster? Smoother? Better MPG?
I've always gotten a bit of a chuckle out of many of the stations around here with pumps that have some crap about "clean", "cleaner", "cleanest", "You could eat out of your tank/engine if you could get in there" on them. Shell and PetroCanada come to mind. They've even got little graphs with 1, 2, or 3 "clean" icons. :_Huff said:Some people buy 'premium' gas thinking it's better, either meaning cleaner for the engine
