I have to agree with cableguy, just run unleaded unless your using a tuner/programmer that requires 91+ octane. Now I'm not gonna say its a waste of money because its not THAT much of a diffrence between regular but if thats what you like by all means go for it. :great:
The less ethanol in your gas the better mileage you will get. If you don't need the higher octane so it doesn't ping. You basically are wasting money. I hauled gas for 3 years and learned more than I want to know about it . LOL
Where did you guys dig this old thread up!? Haha... Anyway, it's a good topic.
I use regular unleaded and everything is running fine at 20,000 miles. I've read that the others are truly a waste of money (for several different reasons). I'm no expert so I can't verify that... just what I've heard.
