Have a 98 Damon Daybreak 32 ft. motorhome that we just got. It has a big block Chevy chassis. Is it OK to run regular gas in this or Do I need to run premium?
most run regular, but should say on the fuel door or the manual. We ran both in ours and it ran better with premium gas but mpg did not go up much. I ran premium in the mountain and it did much better. We live in the mountains, so had a great test bed.
