Recently I've been experimenting with adding a small amount of acetone to my fuel (70ml to 45L) (2 ounces to 10 US Gallons).

I understand acetone is a major ingredient in fuel injector "treatments" so perhaps it simply cleans those out, but I have seen a small improvement.
I am under the impression that acetone is able to reduce the surface tension of the fuel it is mixed with to improve atomization in the fuel injection which is supposed to lead to more complete combustion.

Any thoughts around this?

There seem to be a couple positions people jump to;
1. anything that doesn't come from a gas pump might wreck my car
2. its fantastic I no longer buy gas, it even removed the scratches from my paint and rotated my tires.

Anyone else have experience with using additives like acetone to affect their fe?

Thanks for your input.

Hi G:

___Welcome to CleanMPG!

___Regarding acetone, you are wasting your time and effort as additives in today’s gasoline are heavy with mandated detergents so you do not have to worry about cleaning anything out.

___About the increased FE, any improvements you have seen in FE is because of the "placebo" effect. You are paying attention now and there in is half the battle.

___Hang around here for a few hours and you will begin to use so much less fuel without the snake oil that a smile is almost guaranteed to develop :)

___Good Luck

Acetone - it's been shown many times by many people, no real effect on mileage.

For what it's worth, fuel additive is very nearly required for diesels (at least where it gets cold).

Prior to having this epiphany, I plugged a fuel filter Christmas morning on the way to Grandma's house. It wasn't all that cold (maybe 20's) but cold enough to cause some wax crystals in the fuel. In my ignorant state, I took it to a dealer in the town I was visiting, and for $100, they changed the fuel filter and put in a bottle of Power Service fuel conditioner.
The additive (in addition to curing cancer and solving world hunger) does raise the gel point and fuel filter plugging point enough that you can drive in climates like mine without much worry.

That said, most ______ treatments you might see marketed as a miracle, are probably snake oil.

Thanks for the input guys. I appreciate the perspective.

Hydrogen energy density of fuels. It's hard to beat gasoline as a hydrogen carrier. I think acetone actually holds a little less hydrogen than gasoline so don't waste your time.

The only ones I've seen that aren't a rip-off are:
Chevron: Techron
Lube Control: Fuel Power 60

If you're running Top Tier fuel, these may be needless.
There's instrumented testing showing that certain Lube Control Fuel Power products DO improve MPG, but that only covers diesel vehicles and is only about a 3% fuel savings.

This is the Lube Control Distributors website:

I'm not advising it for everyone, but diesel users should probably at least look at their test results.

My recent 100K Prius maintenance writeup (http://techno-fandom.org/~hobbit/cars/maint100k/) goes into the use of
Techron a bit, and has a bunch of references on fuel-system
cleaning agents that have some good facts on what works and
what doesn't. And none of it is really about MPG, it's just
about keeping things clean.

Hi All:

___What really impressed me was the quality of the fluids after 100,000 miles. That seal and vaccum still intact while in the M5 was a great relief as well.

___I would however service your Flux capacitor as it appears to be slightly under the standard 19 Megazoobs when new. A farx rotation may help but as it goes, you will begin to see your transitory velocity climb from 88 to 88.5 to 89 mph. Anything above 90 and you risk dematerialization effects. Namely, hair growing on parts you would never expect. Check the bottoms of your feet just to make sure :D :D :D

___Good Luck

Checking feet....yep, there is the hair! And I didn't think my car could reach 90mph! :D - Dale

+1 on the Techron. I've heard from many sources that it's truly an excellent fuel system cleaner. Chevron's all that goes into my car (except for roadtrips when I don't find a Chevron), and at least here Chevron is priced the same as its competitors.
