I stumbled upon this article which I thought was very interesting.

Is this another "Snake Oil" fiction or a fact?

The Volvo 240 Guy above claims 2mpg Improvement on his 240!!!!


Another bellow......

* ford escape, 2003 report by WinNIX - When experimenting with different mixtures, use that mixture for TWO tanks of gas. I've learned single-tank acetone experimentation is almost COMPLETELY unreliable. That said, my 2003 ford escape gets 18.5 mpg on plain gasoline. I've had the following success with multi-tank mixtures of the following:

1oz per 16 gal, nothing.
2oz per 16 gal, 1 - 2 mpg increase. Engine idle down by 50-100rpm.
3oz per 16 gal, 2 - 4 mpg increase. Engine noise reduced, idle speed not recorded.
4oz per 16 gal, 4 - 6 mpg increase. Engine accelerates smoother.
5oz per 16 gal, 3 - 6 mpg increase, this appears to have about the same effect as 4oz.
6oz per 16 gal, 3 - 5 mpg increase. mpg is going down slightly. anything above this decreases mpg.

A total of roughly 30 tests and 8,500 miles. 75% of the time i used the same HESS gas station in town. Sometimes, of course, I must get gas elsewhere. Best tank, 23.9mpg at 4oz.

Any thoughts?

In general people who are trying to prove a mileage increase also tend
to drive more conservatively which may improve mileage more than additives.
I think if you figure in the cost of the acetone, the risk of it taking
paint off your car and deposits out of your tank and into more sensitive
areas of your fuel system, and its bad effect on hoses, seals and other
polymeric parts, if there is any improvement at all it will not take long
for some other expense to pop up that will more than negate it.
(Fuel leaks or stoppages probably the most likely, paint damage right up there.)
Then there is the fire/explosion hazard. Acetone boils at a bit over 100°F
and makes lots of vapors below that temp.
