My bad for posting in the inappropriate forum!
Anyway, I don't like to use sunoco with my hemi, it seems to suck back the fuel for some reason... and that was even with a tank of ultra 94. I generally just try and fill up with the Mac's gas station stores, which is generally ESSO. I would definitely prefer to use Shell, however there aren't any stations close to where I live or travel.
Still though, what product, or brand make something that is ok to use for our hemi... Do I just go to the store and grab the first cheapest brand name bottle I see... like Penzoil, or something?
