DJM/78 Posted March 5, 2010 Share Posted March 5, 2010 So for the first time since I bought my truck , I wanted to see how my truck would run on 85 octane fuel . Now she's mad at me , its like taking a supermodel to Taco Bell for a first date .. Anyway , loss of power is amazing , stutters through low RPM's and forget 5th , worthless .... I'm guessing its the fuel because she started running that way as soon as I put it in there . What octane are you guys running and yes I know , it looks like I'll be going through the fuel system and all the vac. lines as well . Even better I'll be doing it in the snow this weekend .... yea ... :dunce: Quote Link to comment Share on other sites More sharing options...
