I saw this on autoblog and thought it interesting enough to share. I take not responsbility for you pouring your wifes nail polish remover in your gas tank.

 

Don't try this at home.

Physically impossible to get 20% better gas mileage by adding less than 1% Acetone to your tank, it's been debunked years ago.

S

 

Wouldn't acetone be bad for your fuel lines? I know it's very diluted, but isn't it highly acidic or basic? I can't remember which, just don't think it could be a good thing internally.

 

Its highly caustic to most plastic/rubber substances. I would not recommend acetone additives.

 

I remember posting in a thread about acetone just a few weeks ago...

 

it shouldnt affect miliage at all, if anything its just gonna take the place of some gas and be the same as if you had an extra gal. of gas in the tank, of course your gonna get 20 more miles out of the tank, when its more full than normal.

all it could really do is boost the octane raiting of the fuel....but im not sure what happens when it burns combined with gasoline and its additives....might damage the CAT as well as O2 sensors and such....not to mention all the fuel lines, pump, filter, injectors and seals in the motor.

 

I knew I had read this somewhere, probably one of your posts because everything looks familiar :D
Anyway, I find it hard to believe and gas additive will do much of anything as for power or mileage. I'm no chemist, it just all seems like rubbish to me.

 

there is already a lot of chemicals and additives in gasoline, things to make it burn cleaner or raise its octane factor or reduce deposits....its really stupid to just MIX some other chemical in.....cause youve got 3 things to worry about, what will this do/cause when mixed with the other blen of chemicals in the gas, 2 what will it do when this new 'mix' burns and 3 what new compounds are left after this 'mix' burns.

Sometimes you can mix 2 harmless substances togehter and get a violent reaction....such as baking soda and vinegar.....in a sealed containter (like a bottle) it can make a pretty big boom.....

unless you test and research the exact ammounts and formulations....theres no telling what reactions might occure....and im not gonna use my gas tank as a test tube

 

Exactly. I read someone else's writeup on the acetone thing and they said "it improves gas mileage by 40 miles to the tank." I called BS and then read up a bit on it. Everyone who knew anything related said it would either do nothing because it was too diluted or annihilate the tank/lines after a fair amount of use. Not a good idea in my opinion.

 

something similar, ive made race gas by adding some of the ingredients of paint/laqure thiner to gas, xylene and toulene, to boost the octane, i think the octane raiting of these by themselfs is 112 or 114, by mixing them with race gas we were able to make what should have been around 98 octane, it was for a school chem project, the fuel ran fine in a beater test car, and we were able to get more power, but ultimatly got less mpg (due to the fact that we pushed the car harder with the new power and that power is made by burning fuel, you can lean a A/F out to get a little more power, but if you can get more air, then you can burn more fuel and make more power....ect ect) so anyway, things like acetone could help you make more power if the car is tuned to work with the new fuel mix, but just pouring it in...shouldnt have any noticable effect.

Also, I have found that running premix on a rotary can increase MPG and Power, just a tad, thats because some of the fuel being injected is actualy oil, so its using less fuel cause it doesnt know the differnce, even this only ammounts to about 1 mpg more. I know this cause for the last 7k miles on the rx8 since breakin, ive gotten 21.0-22.0 mpg and for the last 5k miles ive run 400:1 (gas:oil) premix, and gotten 22.0-23.0 mpg, same route and everything, I did run one tank of regular (non-premixed) and was right back at 21.0-22.0, so its about 1 mpg better, about 15 miles more per tank....its hardly worth it, and ultimately could be due to outside temp, ect. Although my driving habbits are unchanged.

best info I've found so far

 

Long ago, in a country on another continent, without fuel additives, I used on a 4-cyl carburated engine without catalyst or even an ECU, two chemicals: acetone twice a year to clean water from the fuel system (tank, lines, carburator) and gummy residues, and toluene to increase the octane when was getting pinging due to really poor fuel quality.
I would not recommend using either in the Renesis. Might be OK, but why risk? There are plenty of additives that were actually tested in engines... and even then, Mazda does recommend to not use any additives.

 

I've been reading all of the info on Acetone added to gasoline. The WEB information states that 100% Acetone will not harm the fuel system unless you are trying to use E85 gasohol (It is also 105 Octane, but not allowed for use in the Renesis.). The Acetone and Gasohol mixture will cross the seals and polute/dilute the oil.
When the hurricanes caused the price to skyrocket; I gave it a try.
My '04 likes 92 octane the best but at almost $4.00 a gallon - ouch.
I have run every grade available and tried many octane boosters too.
And Shell regular 87 octane with 4 oz. of 100% pure Acetone added to a full tank sure runs well. The Acetone allows the Gasoline to vaporize more completely.

I like it!

 

Ive run 2gallons of xylene in my 8 just to give it a try. I think it came out to be a 96 octane tank of gas total.

Upsides: Couldn't tell any difference subjectively.

Downsides: The pig rich ECU and the xylene make the exhaust really really smell toxic. I'm talking like: you stand behind the car, you get lightheaded and nauseous.

 

Id hate to know what that did to your cat, i hope nothing bad.

we melted a highflow cat with 93* + A mix of other chemiclas, then tuned it for the new mix and ran it WOT at a track for a few laps, the tips of the exhaust shot flames, there was a good ammount of black smoke when first getting on it, it smelled horrible, and the exhaust temps were REALLY hot, when we unbolted the cat, there was nothing there, the honeycomb was completly melted and GONE
