This concentration is so slight that any degradation of seals and plastic components would probably not be measurable. The risk of damage is minimal.
So is the probability of any measurable difference. Good luck with that.

Agreed. But the opportunity cost is low.

In all seriousness, if you do take it to the test, I'd like to hear how it works out.

and don't be afraid to tell us if the IP ends up going south as a result.

Correct me if I am wrong, but, I don't believe that there is any rubber or plastic inside the IP that would cause a "going south" result.

I'd be more concerned with the fuel hoses and lines, but, only after many years of use.

I doubt that acetone would do any harm. Gasoline is a very strong organic solvent as well. Gasoline exposure would have the same effects to most rubber and plastic that acetone would especially in small concentrations. However I think a little white lightening in the tank would do the same thing or better. BTW they mandated the lightening in our gas here in hotlanta and it increased our fuel prices. Darn EPA throwing a bone to the agriculture products lobby.

Yep in CT also we are stuck with alcohol in gas, it is really screwing the marine industry. Lots of filter and fuel pump problems since they started doing it.

The curves of the chart in cited link...

..appear too perfect and smooth to result from real data points. I suspect someone just draw them without having any data at all. I have not found any real data on the web, just some anectorial evidence. Has anyone found solid data?

So it looks like stronger solvents are a bad idea period. If you want to experiment have fun but adding more powerful solvents to gasoline is a bad idea especially when better solutions are out there. The state of Georgia and the environmental hotbed of California oppose this alcohol. I wish we could grow enough soybeans to go biodiesel/veggie everywhere.

They have mandated alky in gas (gasohol) in most metro areas in the US during winter months at least. Seems the thinking is it will reduce emissions while the gassers are all idling to stay warm.
Noticed a few years ago that with 15% added alky to gas, the mpg dropped by about 15%. My neighbor was active with state politics back then and he started a phone calling campaign asking why the crap was so good. Finally got the study papers, we could not determine any benefit in that set of reports. A little lower emmisions per gallon was how they measured, but they did not take account the increase in fuel used since the mpg went down, and thus more fuel was burned. That set of reports even admitted the fuel economy was likely to drop significantly, but did not attempt to measure the noted drop.
News at the time was that the farm lobby wanted the program to get sales of their product going.
Haven't followed that story since I moved away from the old neighborhood and my old neighbor died.

But that is on the assumption that everywhere wants to go diesel. Even in europe, they are only at 40% diesel. We are nowheres close to that even. Many people here don't even want to hear the word diesel when it comes to buying cars. For all the benifits of lower fuel bills, it has it's own issues that you have to put up with too. Simply put, diesel is not for everyone. I went diesel because of the kind of traveling my wife will be doing for the next couple of years. If her job was within a 10 mile radius, I wouldn't have. At least not for all the issues it brings with it. Having to wear gloves to fuel up, fuel mess on the floor which you track into the car, possible gelling in really cold weather, lack of advailability of fuel as opposed to gas, the foaming when filling, etc, etc.

Our gasoline in Denver has had 10% alcohol (ethanol) for years, since they did away with the MTBE. I've never had an issue with ethanol in gasoline since I $hit-canned my old carburated Honda 15 years ago. A good fuel filter and EFI loves ethanol mixes, and yes, the fuel mileage goes down because there is less energy per unit volume in ethanol.

This claim for acetone improving mileage at miniscule concentrations is a bunch of hooey; the "theory" of better fuel vaporization leading to such outlandish mileage improvments will not pass the common-sense test. Look at an emmisions test report from a gasser: HC emissions limited to 400 ppm, for example, on my '78 280Z (no cat). It puts out about 120 ppm on premium fuel. If acetone dropped the HC ppm to zero, where is the mileage gain going to come from? 120ppm HC won't gain me 5 mpg from the 28 mpg the car currently gets. Use your brains.

Old300D, you actually expect common sense and the internet to be intertwined? Keep dreaming...

I used to get slightly higher mileage running alcohol blends in my 91 Skylark. Not much to be certain, but it was just a tick higher. I was sad when I moved to Oklahoma and could no longer get ethanol blends. Now that I moved to Kansas I can get them again, but no longer own a gasser so it does me no good.

THose ethanol blends usually result in worse economy on most cars....

This is a good point. Also, there is other more promising technologies on the site, such as fuelless engines and cold fusion. I too, wish the solution to our energy woes were as simple as a few spoonfuls of acetone. Unfortunately, reality is not flexible.
