Is this likely to have any negative effects upon my engine (the acetone)?

Or is it likely to make any difference at all?

I'd be concerned for the effect of acetone on rubber tubing, as it tends to dissolve the rubber, leaving it brittle and subject to cracking. It also softens plastic. You might end up having to replace all the rubber tubing in your gas line, and that might cost a bundle. More than what you saved in the first place.

Having read few a few forums where they are discussing this I am not sure that it is that effective anyway.

Good thinking Amaranth, regarding rubber deterioration.

I understand that during World War II, mothballs were sometimes added to the gas tank.
How many were added per gallon, or for the reason why, I do not know.
Prehaps someone in the UK could ask their Dad? I would be interested.

Definately , newer vehicles use rubber and synthetic tubing. A good test to see if the materials in question will react to each other is to, for example take a piece of tubing and place it in acetone in a covered jar for a peiod of a couple of weeks. If it swells then they arent compatable. I found a good resource site on gas mileage and prices @ http://www.sonomabuzz.com They test what works and list hundreds of techniques.
