I only run Chevron 93.

So far I've run five tanks of Chevron premium and 13 tanks of E85 (being Irish I enjoy the idea of burning alcohol, plus it doesn't hurt my feelings to be breathing a little bit cleaner air). That's not really enough of a sample size to say anything definitive, but so far the cost per mile is fairly close - premium generally a penny or two per mile cheaper. I'm a numbers geek so I'll be keeping track.

Enjoy your new rig!

Chevron premium here, except for my cross-country run where I put premium in from whatever station I could find that made me feel the least squeamish. One tank of E85; I think I need to have my E85 tune a bit more refined.

i'm not too picky on brand but only stick to 91+ (usually 93). i try to find the cheaper stations that sell a lot of fuel.

i've noticed almost no difference at all. if you are nice to it and stay 65 or lower you can get great mileage. if you enjoy that 6.2 and or stay 70 or higher your mileage will suck. simple as that. i put mine back on for a long road trip and i've been too lazy to take it off since i've been back.
