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.
I tried that last year with my old Toyota truck with 240,000 miles on it back then. I didn't noticed a change at all. Maybe because of the miles it has already. Maybe it will do well with the newer trucks. if you try it..post your results if you don't mind.
Nothing wrong with thinking outside the box,making sure you understand outside the box is a different animal.
Without a UCL added your most likely to have an issue.
Smoking the primary cats wouldnt be out of the question,but the least of my worries if you asked me
Just find acouple gallons of 110* and add them to your ¼ full tank of fuel.
You'll know within 2 miles if the accetone would have been a good idea or not.

I will be more than happy to do the testing on my '07 DC...after I get my first oil change at 3K and have a reference.
I'll post my results in the TS forum. I don't expect great results because I believe the engines do a pretty good job of burning the fuel efficiently. Might see a little more power...and that would be good on the low side.
Gotta' test it to find out though.
Sometimes you gotta think outside the box...right TNK?
You're going to do a fuel system experiment on your new Tundra from something you read off Google? ok...
Try it on your lawn mower first. If you finish your mowing faster than your neighbor Jim, the Mythbusters would applaude you.
Here's some science for your reading. Flashpoints of various flammable liquids:
-45C, ether
-43C, gasoline (petrol)
-18C, acetone
22C, ethyl alcohol
38-72C, kerosene
62C, diesel
If you don't understand what a flashpoint is, wiki it or go to sigma-aldrich.com and read the MSDS on every CAS# you can find on the bottle. They'll give you a free MSDS copy for anything they offer. Safety first!

Thanks for the warning. I work in the chemical industry and am well aware of flashpoint. I design equipment to recycle Class I Div 1 chemicals everyday...it doesn't get any tougher than that as far as electrical/explosion safety goes.
I added 7 oz's to a tankful of Texaco 87 Octane today. I will be logging the data over the next month and will report my findings to the TS gang. I decided that since I still have over 1,000 miles before my first oil change I can still establish a baseline reference from my other fuel logs and should get some good information.
I would never suggest someone try something without doing research first. I have done plenty and I personally feel the risks are insignificant. The gains are yet to be seen since I will be the first documented tester on the 5.7 Tundra.
Got one TB ported and finally got the truck to accept the change(sounds like a moose horn)
Abit of help from DEEP South Texas pointed to the solution They rumored a Full ECM platform(simular to the GM LS-1 Edit) is in the works sadly the bird ran out of chirp shortly after that
Thought about welding the spider gears up ?
Got another warning from the local law dogs on the dumps
We'll eventually get one built and disclose the fruits of our trials and tribulations from the "BARN" or 1000 Posts which ever comes first

Keep in mind that Acetone is a SOLVENT and any & all rubber/plastic hoses/parts that it travels through and/or touches will be subject to damage or being dissloved. In a race application where the engine is being torn down on regular basis it may be worth it, but I would NEVER put it in a daily driven vehicle.

I fill the tank half way...dump the acetone in...and continue to fill it to the top.
I'm adding 7oz's to the tank so that's about 475:1 ratio. You have to get below 150:1 to see minimal negative effects such as minor swelling of certain rubbers(of which probably aren't in this fuel system anyway)...over the long term. 475:1 rate should have no effect...other than better combustion.
I will add one other note. I added the acetone, finished fueling and went inside to talk to a friend for a few minutes....truck was running. I came back out and the truck was dead..................so I thought. I open the door up and notice that the engine is running....VERY QUIETLY.
That can be bad or good depending on how you look at it. Since the purpose of my test is to increase MPG and Power...I won't worry about the quietness for now.
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.
Initial report. Truck is definitly quieter. The low end torque(under 3K) is through the roof! It might even be considered annoying by people that don't like getting the old neck snapped. If I barely touch the accelerator the "dog hunts" as TNK would put it.
MPG was lower for about 20 miles with cruise running 70. I think the computer was making adjustments. Today I averaged 21.8 running 70 with S6 and VSC off in cruise.
I am going to run 3 tank fulls at 3oz per 10 gallons, 3 @ 2oz, 3@1oz and record the MPG and overall feel of the truck. Between the acetone quantity changes I will run straight gas with no acetone.
All tests will use Texaco 87 from the same gas station.
Once I figure out the best % I will experiment with different gasoline brands...Chevron, BP, Amoco, etc....

So, acetone is a solvent.
So are toluene (up to 35%), MTBE (an ether, 7.5%, up to 18%), the benzenes (monocyclic aromatics, up to 13%), a host of alkanes (almost all isomers from C5 to C12), and ethanol (up to 10%), all components of gasoline.
Every component of gasoline but one (the polycyclic aromatics, up to maybe 2%) are fantastic solvents for almost all non-polymerized compounds lacking a dipole moment. Water is one of the few compounds they don't dissolve (but if MTBE or ethanol are present, gasoline will solvate a small amount of water).
So why doesn't every fuel line and seal dissolve and crumble under use? They are designed to withstand solvents! Solvents are, in fact, the only thing that goes into your gas tank.
Knowing the properties of the rubbers and plastics used, and the properties of the gasoline compounds involved, I'd frankly be astounded if the manufacturers managed to find a polymer that withstood all the compounds present in gasoline but was susceptible to acetone attack.
P.S. I'm using the term solvent, as I presume the poster I quoted used it, to be those liquids that will dissolve compounds similar to the vehicle components typically exposed to gasoline: rubbers, plastics, metals, and possibly ceramics. The proper definition of solvent and solute depend more on the bulk of material found in each particular solution; gasoline is properly a solution with all components dissolved into the others; given the number of components in the solution, it would be difficult pointing out a single compound functioning as the solvent.
P.P.S. I am not a polymer chemist, nor am I a petroleum chemist. Though I say I'd be astounded to find a polymer that would react with acetone and not gasoline, I don't know that such a polymer doesn't exists. I am a Ph.D. inorganic chemist; I study the broadest range of compounds, their properties, and the bonds that hold atom to atom, and molecule to molecule, thus imparting the bulk properties to the material.
P.P.P.S. I honestly doubt that adding acetone will do anything to the milage you get per tank. I don't think combustion reaction mechanisms support acetone in any catalytic role, and acetone has a lower energy per ounce than gasoline as a whole.

You are right in your assumption.
Acetone benefits the gasoline by lowering surface tension...hopefully creating more efficient vaporization and combustion. That's the theory anyway...we shall see.

That's why it's taking a little longer.
