I just recently loaded "GAS BUDDY" into my smart phone and the app has selection for Regular, Midgrade, Premium, Diesel & E-85. It really helps to find the lowest price for Diesel. For example, truck stop on I-95 near Jacksonville, Fl. is $2.09.9 per gallon but down the exit ramp about 3/4 mile is diesel at a Speedway for $1.74.9. Quite a difference for driving 3/4 mile. as a prior post stated, the truck stop is not always the cheapest fuel even with the discount card from GOOD SAM.
