With out the additive I average around 14-17 mpg. This is a Tow truck so with the added weight of the wrecker unit, thats great gas mileage. Suggestions?
I have found that my mod's have done little to improve fuel economy. They do though, greatly improved the performance. The more miles I get on my truck, the more my mpg improves. Your mpg sounds very good, what additive are you using?
