I've came across some readings about adding acetone to gasoline to increase MPG. Anyone else come across this or have any thoughts good or bad about trying this. Thinking about trying it out on one of our Government rigs first to see.
That's been around for years. From what I've read on other forums, it's not worth in and could possibly void your warranty if the acetone causes any problems. I wouldn't mess with it.

Virtually any modification to your engine or to the gasoline will increase the concentration of emissions the engine generates which in turn accelerates the deterioration of the emission system components which in turn ends up causing an eventual DECREASE in engine power and fuel economy.
Acetone has one really good use, however, - it very effectively removes old stickers from chrome bumpers and window glass. Wear rubber gloves when you use it or you'll find it will melt your skin as well as it melts away old bumper sticker glue.

Acetone has been used for many years by women and Boy George to remove their nail polish. It does not melt skin under normal use but I sure wouldn't pour any of it in my gas tank.

Acetone doesn't melt skin, but is absorbed through it. Not cool for your liver, but then there are other colorless liquids that are known to do a number on your liver and people drink them all the time.
Acetone is part of the keytone family of solvents. As a fuel additive, it is suppose to make the fuel atomize better by reducing surface tension of the gas vapors. It is also very hot meaning that it evaporates extremely fast. The problem is that just a few ounces per gallon will have next to no effect. It is also a plasticizer meaning that it can and will dissolve any plastic components in your fuel system including the gas tank. Again, a few ounces per gallon is not going to have a great effect. Some of the fuel system cleaners like Chemtool use it for the base cleaning agent in their product but, they also will add other solvents and anti-corrosion agents to the mix to eliminate any damage to your plastic parts. So, is it worth using? Not for fuel mileage as the amount used is far too small to have any benefit. Using more will damage the fuel delivery system. If you want to use it as a cleaner, it works just fine at 2oz per gallon of fuel. But I wouldn't give it a steady diet of it. Frankly, buying Chemtool makes a lot better sense for maintenance cleaning and BG44 for every 50,000 miles for a thorough fuel system cleaning.
Acetone is also a great paint remover. Use with caution around your truck.

I had a student (I teach chemistry) who was talked into selling repackaged mothballs (napthalene) as a gas additive "pill" to improve gas milage. He was told it would drastically improve his miles per gallon, I told him it couldn't, and told him to check it himself. He came back next week with the report that the pill made no difference and he had quit that sales job.
If you want to find out if it works, try it, and see if it makes a difference. I won't tell you acetone is a stupid idea, because you should never trust anything you read on the internet. Half of it's written by people who are below average.

I did all those searches a few years ago and found all of the links you've posted and several more. After some research of my own I decided to try it on a few of my vehicles including my wife's commuter (Audi A6 4.2L V8) and noticed little to no difference (+/- >0.1mpg) between using it and not using it. I did lots of testing in various seasons (since Colorado has all four) and various conditions and types of driving and the end result was I was out ~$5 for a can of Acetone and all the time it took to research and document this nonsense. If I had it to do over again I could have used that same time to make enough money to make up for several MPG worth of fuel economy.
Summary: It's an urban legend and nothing more.

3 ounces per 10 gallons is the best mix from college studies I have read.
On certain vehicles it works dramatically. At this concentration you would be looking at .2 percent of acetone. Above the 3 ounce per 10 gallon mark and you will start to lose fuel mileage.
At the recommended .2 percent you could run for years and not hurt a thing.
You should add 7.8 ounces to a partially filled tank and then fill it up to the top(at a gas station of course). This would help to blend it.
Try it for a tank and check the results. One tank full won't hurt a thing.
Adding Acetone?
