As far as regular vs premium gas, is it true that you get better MPGs with premium, even though it costs more overall?
No. Unless your car is made to run on the higher octane. If you put 91 octane in an svt it will get better fuel mileage than with 87( Not that I would put 87 in my svt). This is because the svt is designed to run on the 91. Google octane if you really want to know more.
