Since a lot of us use Sunoco in our cars I thought that I would pass on that you can get a Sunoco Master Card with as low as 12% APR and you get 4% rebate on gas purchases. I am in no way affiliated but I just signed up since saving 4% on 94 octane make me happy

I've been using the Shell Mastercard for quite some time. They give ya a 5% rebate on gas and 1% on everything else. The highest octane I've seen at Shell is 93 and that's what I use all of the time unless I can't find a Shell station (rare occurrence). Just my two cents...

Shells arent that prevalent where I go.

Plus they sell Sunoco race gas at Cecil AND they take MasterCard

I'll tell you what, this is ONE HELL OF A DEAL. I buy gas every 3 days. If I could get one for a MOBIL gas, I'd be skippy! Sunoco's are non-existent on my daily travel route.
