What gas octane???
Users of the big gassers: Dodge 6.4, GM 6.0, Ford 6.4....... Can the lower octane be used or do you need the higher octanes????? Colorado we have either 85, 87, or I think 91..

I always thought gas was gas no matter where you buy it until Sheetz came on the scene. Gas from there will make anything I put it in run significantly worse with less mpg. Jeep's, Harley's, Lawn mower's, and my wife's Fiat. Trucks are diesel. My old ragged out sporty will pretty much run on whale piss but Sheetz gas will make it ping! To get back to the original topic we always run mid grade in the jeeps and premium in everything else.
