Lower Gear ratio better mpg?

[djvx]

Without doing any ratio changes of my 10-11% increase in tires...I roll about 15.7 average per tank. I ride 265.75.16. My procomp rims are not too light. I have acheived 17-18 before but the work involved was not worth my time. It concerned acetone.

I don't understand exactly what you mean.

I don't understand exactly what you mean.

There is a recent urban myth about adding small amounts of acetone to gasoline to increase its efficacy.
