ONLY shell V power (93) for me
Hess runs horrible in the G....I think it's because of the 15% Ethanol they have vs. 10% elsewhere.

 

93 octane here in Charlotte, N.C.

 

Shell V-power!!

 

Most of your discount gas stations add less detergents than larger companies such as Shell or BP/Amoco. The detergents are an added expense, thus that's why these el cheapo stores are able to sell you gas at a lower price most of the time. You can always add your own additives and detergents at a nominal cost.
