The salesman who sold me the SS put regular 87 octane in. Damn jack wagon. The truck was driving the shit. Shifting hard from 1st to 2nd. As soon as I got 1/2 thru the tank I put premium in and o' lordy. Drives smooth and like a bat outta hell. So long story short....yea the SS hates 87 oct. and loves premium.
