Be sure and get one of these, so you can keep accurate track of your mileage.

[Cpaulv]

to what I read it won't work on my car, but I could have misread something. Thats why I haven't gotten it yet.

Maybe not as classy, but a calculator, a notepad and an odometer would do the same thing, no? ;-)

[Cpaulv]

thats what I use now.

Not accurate enough.

........ For those of you who like to see the data yourself, there is a great little device available to check your exact gas mileage and more. See ScanGauge for an instrument that fits any car 1996 or newer. And some 1995 models. It measures your real-time MPG, inlet and coolant temperatures and many more details as you drive. This inexpensive tool should end a lot of debate over what works for mileage and what does not. We use the TRIP function to average the MPG at a steady 50 MPH both ways ........
A reputable site such as http://www.pesn.com would not suggest you buy their own product, unless it was far better than your primitive method.

Acetone is only one, of the many "gas saving" secrets that the "big oil companies" have been able to keep from the public for the last hundred, or so, years.

I just joined an Acetone yahoo group, they have databases where people test before and after with acetone in their gas....a few state their driving conditions. Truth is, that stuff varies from day to day, who's to say they didn't get into a traffic jam with plain ol gasoline and got a measly 18mpg for the week (or perhaps left it idling in the driveway). Then they fill it with some acetone, ooooo....25mpg...incredible because the traffic was clear or some other factor...but the acetone had to have done it.

Ok, so you see my point, you need EVERYTHING to remain constant, except for the variables that you are testing of course for a proper experiment...here's what appeared to be the most accurate I could find in the database on Yahoo:

Car: 1999 Ford Contour
Engine: 2.5L V-6 w/5-Speed Manual
Notes: HW driving round trip with similar conditions from point A to B to A stoping at the same stations for Gasoline both ways (measurement device melted along the way and limited amount added)
Normal MPG: 31.58
Acetone/Gas ratio: 0.235% and 0.121%
Average Speed: 70MPH
MPG after Acetone: 31.01

It doesn't stop there....there is also a 1999 Cougar on there, 29.2MPG normal...after acetone, 26.2MPG.

Good stuff...would never see me pouring that into my tank. I do use this though.

Unfortunately not, there seems to be a huge gap of inactivity for some reason... :-k

you see you never stated things like engine condition, was it a bit more windy on that day or days, did the acetone clean some of the deposits and let some oil or other things leak, was it more humid, also the type of gas was used, there are many many more things to consider before one can pass judgment on something else.

Right...and this is why the Mythbusters episode, where they simply idled the engine, controlled conditions testing...is most accurate. As was stated by 87delta in the topic linked by norm, they lost a couple mpg running the engine off of acetone.

From what I recall seeing the episode, they used a test tube to hold the gasoline or gasoline/acetone mix so they had accurate measurements, didn't actually drive it, and just let the engine run. That's about as good as it gets as far as accuracy goes.

How about Kettering Universitys tests?

Seems that Louis LaPointe edited his original article after it was published and the Mythbusters episode was aired.

They apparently suffer from unlimited corporate GREED. They may want bad mileage. It seems that way because if they wanted good mileage, we would have excellent mileage. So we get worse fuel, not better. Just look at the SUV mileage situation. They have perhaps encouraged programs such as MythBusters, radio shows and other media that feed on controversy to squash the possible widespread use of acetone in diesel fuel and gasoline. I have consistently turned down being on talk shows or doing magazine articles. The opposition stories are based on single tests to deny the benefits of acetone, xylene and other additives to improve your mileage ........
Everyone is being paid off by "Big Oil", and he cannot get his message out. Or is it that, he cannot get on the (very lucrative) talk show circuit, because they all think he is a "scam artist".

Note the words probably, apparently, may, perhaps, and possible, in that order.

Why am I still not surprised?

There has been no mention of the effect of acetone on a diesel vehicle... I remember reading about truckers using it in their fuel and benefiting from it.

I would tend to think there has to be some truth to this "myth" in some shape or form, or at least some conditions that have lead so many people to believe it works...

I believe it could help a gas engine atomize fuel more efficiently, when running poor fuels, with some water content. Not sure whether or not to believe it improves mileage under normal circumstances.

From the same article:

lubedev.com wrote: ........ Acetone operates on the unburned portion of the fuel through better vaporization to improve combustion efficiency. It improves the probability of successful combustion. It bumps the Thermal Efficiency of all engines--over 25% for gasoline and over 35% for diesel. Acetone and xylene further operate like electron absorbers to protect against detonation or rough running and against water in the fuel. It is the ideal additive for gasoline, jet fuel and diesel fuel. There are no bad effects whatsoever and there is every good reason to use acetone in your fuel ........
25 and 35%?

Placebo effect?

Not quite sure how. Everything I'm reading right now (Here is one source I was reading from) says that Acetone is soluable in both water, gasoline, and diesel. So, it will emulsify water into the fuel, instead of the water and fuel separating, and picking water straight off the bottom of a fuel tank. As I understand it, this is similar to gasline antifreeze. (why not use gasline antifreeze, if water emulsion is the goal? ;-) ) Nonetheless, the effect is present.

There is also debate as to whether this is desired or not - in a diesel injection system, you want to DEmulsify water into a collection bowl, so the pump never sees any water at all.

The average person will not have a water extraction bowl to bleed water from the fuel system in a gasoline application. They must use an additive to pass the water from the fuel tank. Acetone sounds like it might do the job in a pinch.

Looks familiar. Wiki format does also.

And improve fuel mileage? What does it do if there is no water?

Quote: ........ why not use gasoline antifreeze, if water emulsion is the goal? ........
Acetone is cheaper?

Debate?

Quote: ........ you want to Demulsify water into a collection bowl, so the pump never sees any water at all ........
Sounds like what one would find in any diesel fuel system.

The average person does not have water in the tank.

Quote: ........ Acetone sounds like it might do the job in a pinch.
If there is enough water to cause a problem, how much acetone should be used?
