Next mileage update from me:
Still holding at 22 M.P.G. with the ounce/gallon ratio.
Undummy, I'm currently using Maxima's Super M 2-cycle oil. I am going to switch to their Tundra product, as it has the same ratio of additives, but is mostly petroleum based, and has a lower pour point. A big cost factor is that it is almost half the cost of the Super M.
I tried that lean of a ratio to start with, and it really didn't do much. So far with my experiment, the ounce/gallon ratio seems to give me the most "bang for the buck" so to speak. I also realize that there are probably going to be differences switching to this 2-cycle lubricant, but as I said before, at half the cost, a M.P.G. loss would still be considered a big plus for the price, and the extra lubricity in the fuel quality to boot.
