Result of the first dose of Xylene, 1.35mpg increase.

Went from 32MPG even to 33.35 MPG, and the car idled more smoothly, no hesitation etc.

keep in mind, the dizzy isn't timed correctly either since I haven't had a lower timing cover since I put the engine in.

I'm running a second tank of the same fuel to make sure whether I will get the same mileage or not, w/o the xylene added.

Basically, if I get the same mileage, it wasn't due to the xylene... if I get less mileage, it WAS due to the xylene, and I'll add more next time I get some.

The second tank is from the same batch, same pump, at the same gas station. This is a control tank, testing the actual result for validity.

There would be several explanations if I get the same mileage on this tank as the last one, one of which would be that the excess Xylene helped clean stuff out and make the engine run more efficiently.
