What kind of engine? I've always heard that most engines don't require premium gas. It's usually high end sports cars with specialty engines.I have a SUV that has run nothing but premium gas it’s whole lifetime. Says run premium gas so I do. 5.77 a gallon. If I keep my foot out of it and babysit the pedal I get 18.5 miles per gallon.
Madison county 4.99 to 4.89 for the other cars and truck. Needless to say I drive the other cars more than the premium SUV but I do put some miles on it.
Since the lockdowns did not hold the gas prices seem to. A better job of keeping people at home.
