Acetone is too volatile for it's own good, by the looks. It's difficult to handle and doesn't go boom nearly as well as ethanol. Since there's no real benefit to putting it in the fuel, there's only a lot of negatives and it's not worth the bother.

I agree about the energy content since when I looked up it's heating value, it's lower than for gasoline. At the same time the acetone itself isn't being burned as fuel (at least that's not the intent). The concentrations are usually less than 1% in most cases that have been tested so it must be doing something to the gas....like a catalyst. When you say there's no real benefits from adding it, what are you basing that on? I would think the volitility alone is a plus. Ethanol is also fairly volitile.

Yeah, the problem is everybody's cars are different and so are their test conditions. I saw this really sad video of this guy trying to test acetone by doing multiple trials but his tank was at various levels of fullness during each test and he dumped a "coke can" worth of actone in and didn't figure out the concentration. Test was total crap IMO. Some ppl say nothing happens, some that they get 2x the mileage, some that their mileage dropped. I think the only way to know for sure is to take a couple of different vehicles (maybe a civic, an F-150 and an Altima 3.5 for example) and for each vehicle you'd measure mileage, 1/2 city, 1/2 highway for 100 km on the same route, same day and then dyno the car on the same tank. Do these trials with and without acetone. Would be nice to try different concentrations as well but this would make the number of experiments a little high. That's probably why nobody has done it yet. All the tests I've seen have incorporated some but not all of these elements. I'd love if someone else could point to a test that covered everything.
The high autoignition of acetone is kinda nice. I believe it's this characteristic that makes it a more effective octane booster than ethanol or an equivalent in lower concentrations. If nothing else a straight substitution of acetone for ethanol might mean 94 octane gas at only, say 5% acetone rather than 10% ethanol.

oy, that was so wrong. also it's missing the walrus 'stache, more e-trauma. :eek:
