[pynner]

Since we live in Canada, so it's a bit different.. but we use:

Chevron (1st choice)
Husky (90 octane for the price of low grade... very nice!)
mohawk

while in the U.S:

Chevron
B.P


Ones we avoid like the plague:

Shell (everytime we have used it in the past, it ate through injectors.. terrible gas!)
Esso (mostly political reasons.)
Petro-canada (just not great gas)
