f1ss Posted August 27, 2011 Report Share Posted August 27, 2011 Anything below 91 and your engine will take a big crap on ya, your gas milage will also decrese. It wont crap the bed immediately but will after repeated use (honestley dont know how long, but that is why the manual says 91 octane only). Have to pay to play with these trucks. I wont even run 91, only Sunoco 93, Shell V-Power 93, and Mobil 93. I wont even touch Cumberland Farms, Hess, BP or any other cheap gas station.

Cramer Posted August 28, 2011 Report Share Posted August 28, 2011 My buddies dad used to race alot, and had a 300gal tank of 110 at his house. We would take our street bikes and quads over there and fill them up. He only charged us $2 a gallon when it was about $4 something at the track. There is a station about 25min away that sells 103oct. To the OP: There are alot more benefits to running the proper grade fuel than the con of the price to fill up.

2001silverado364 Posted August 28, 2011 Report Share Posted August 28, 2011 You can't compare foreign octane to U.S. octane, it's measured differently. Their 98 is like our 93 basically. Little bit of info. Quote Link to comment Share on other sites More sharing options...
