100% ethanol free gas will increase your mileage, but the additional cost will probably not be worth it. The addition of fuel additives may help to clean an injector but will not help with mileage.
Basically if you do everything that can be done to increase the mileage, the only thing you will accomplish is going from really terrible mileage to just terrible mileage. RV's are not designed to be fuel efficient, even if it is a diesel. I've had diesel RV's before and the mileage is still bad, altho not quite as bad as the gasser. Of course diesel costs more so it is a wash. The only thing the mileage log will do is just remind you that the enjoyment from RVing far outweighs the cost of fuel. You are better off using the credit cards, like PenFed that offer a 5% discount on every purchase of fuel. There are other CC that may be better but that 5% discount is more than you will get from any additives.
