Shell, Exon, BP etc.Which places have the best gas in your opinion? Loves, QT, Racetrac?
pretty sure QT, Racetrac are good, but be careful about Raceway as they are independent and buy their gas from whomever is cheapest.
Diesel? Most of the big names are fine, just stay away from the places where they have only a slight customer base for diesel. Those tanks are not cycled fresh and will give you problems with water.
