Adding acetone to gasoline

[ChazInMT]

Stovie....you messin or are you serious???? I only ask cause it seems like you've been hanging around a long time, and by now should know that driving habits, trip routes, wind, temperature, tire pressure, air conditioning, and golly knows what else mechanically with your rig can all combine to make 18% differences easily. Not to mention the acetone may have perhaps helped clear a wonky fuel injector or something. (OK, technically, I might have mentioned it sorta when I didn't mention it right there) My Honda Civic has gotten anywhere between 26 and 43 MPG over its life with me (40% Difference by your maths).

Aaannnny way, just wanted to put that out there lest someone think that a simple single tweek in the fuel could get us all 18% better mileage.

If you're looking for a cleaner burn (to pass emisisons, etc) you can run denatured alkyhol mixed in your tank, but as with most anything else you can buy at the local home improvement store it lacks the energy to be a good fuel source.

That said, it WILL clean your fuel system for you, including knocking stuff loose from your fuel filter and into your injectors, lol, so replace the filter first before trying.

Also you need to burn through as quickly as possible since any of the alkyhols can accumulate moisture in the fuel system, and water in gas (or diesel) is bad juju.

In conclusion, good cheap way to potentially make your engine run better and better economy as a result of cleaning things, can also help pass emissions as alkyhol burns clean, but as with all things no free lunch as there are ways it can make the situation worse.

E85 is way cheaper way to get Alcohol, denatured with gasoline.

Didn't give the Stratus good dosses of E85 till after 150,000 miles, now at 245,000 never a fuel related issue

Altima didn't buy till 150,000, I've put 2/3 of a tank of E85 in it several times with no issues.

I put half a tank+ into my cobalt every other fill or so. Lose a few mpg but essentially same cost per mile. All my non-ffv cars take it just fine, get a CEL after 50% but all start and run the same.

I don't know what it does to emissions as we don't have testing here.

Alcohol chemically likes water better than gasoline so will bind with it and separate from the gasoline, but it will pass threw the engine just fine. It will essentially remove the water from the system, that is why we used to add Heat with every fill before E10 came out.

In Brazil they leave 4% water in the alcohol they use for fuel. They've been doing it along time so it must not be a problem. E25 is their minimum alcohol level all the way up to E100 or really E96 with 4% water.

Hi Rooster, all good points. We don't really have E85 here (not a station within 25 miles of me anyway) so that's why I brought up denatured alkyhol. I was trying to specifically call out the denatured variety vs the folks who want to use rubbing alkyhol because the rubbing version, even 91%, has far too much water content and depending on climate, your specific engine, etc it can cause issues and potential damage, so for me erring on the side of caution it's probably better to be safe than sorry.

Depending on local laws and such you could always find a station that sells 100 octane unleaded or Torco fuel additive, mix that and then run a super aggressive tune to cut the fuel quantity back and rely on the higher octane to prevent detonation, plus 100 octane just smells amazing coming out the tailpipe at $7/gal lol

Most of the country does not have E85.

[roosterk0031]

Never looked for denatured before, over $6 a gallon if buying 5 gallon jug at Menards.

Never thought about E85 not being available down there. Up by the gateway airport a Valero had it for $1.65 a last month. (41 total station in the state)

NM only has 10 stations in the whole state, most recent prices are several months old at $1.61

I paid $1.70 yesterday, E10 is $2.10, they pretty much hold the 20% differential that matches my FFV cars FE difference. (247 stations in Iowa)

I'm serious!! I've done a lot of stuff to test it out, and I can gaurentee it was the acetone!! I'd use around 4.5 ounces in my tank. I looked into it before and found out that there's usually about a one ounce of leniency in how much you use! If you use too little it does nothing, if you use too much it drops fuel economy!!

Must... not... be... mean.... whew.

[stovie]

You guys keep talking about how acetone and hydrogen reaction chambers don't work or will never work, but I've had personal experience with both of them on vehicles that would not improve mileage no matter what I did would get 18-25% improvement with acetone or hydrogen. So you guys with no experience can keep badmouthing these things and I'll keep saying your wrong because my personal experience proves otherwise!!!

[Frank Lee]

That's two problems right there: you don't have proof, and there isn't ANY theoretical basis for that level of improvement. Oh- three problems: nobody else can credibly claim results like that either. Give it up Man, nobody here is buying it.
