In your experience what gas are best for mileage.
I prefer to use shell in my area, but there are many brands of gas that are not here in my not so metro neck of the woods.
So my question is this: in your experience what is the best gas for mileage??
never have seen the thread... there are some brands of gas that i will not buy because of poor mileage.
Conoco, speedway, marathon, clark. I don't know if some gases are cleaner, have additives, less alcohol or what, but some do outperform others when it comes to mileage.
