Acetone Fuel Additive Update

LC · Sep 22, 2005

Here in the Northwoods you can buy (labled as 100%) acetone in 1 pint bottles at Walgreens.
$3.99
You should note: ethanol seems to significantly dampen the effects of acetone. The higher the portion of ethanol in the fuel, the more it inhibits the positive effects of acetone.
So if you are going to try it I suggest a non blended fuel.

How would someone go about finding fuel that is not blended? Most stations do not post on their pumps whether or not their fuel contains any ethanol. At least not around here.

People that I know are using 2 oz of acetone per 10 gallons of gasoline. If a lot of people started there it would be a safe dose and enough to look for results. I don't think a dose of over 4 oz per 10 galons of gas is needed.

3 oz per 10 gal seems to be the "sweet spot" per lubedev.com
P.B.

That is what I was using and I got 3.1MPG increase.

That is significant.

Inspired by this thread, I went to Ace Hardware and picked up some Acetone. I found an old plastic cup failing to find a good measuring device. The plastic cup was about the size of a shot glass. I dumped in about 2 cups full of the plastic cup figuring 1 shot is about 1oz. took our gas can and washed whatever Acetone remained in the gas fill line.

No results yet as far as already seeing mileage improvement, acceleration loss or gain, etc... Will see later on,,,AR

Reset you engine computer by pulling the negative cable off of the battery for 10 minutes.

This will quicken up the relearn process.

Thermal oxidation of acetone behind reflected shock wave
Takao Tsuboi, Kazuhiro Ishii and Shigeru Tamura

Introduction
Acetone will be one of the fuels for automobile engine in the future. Miyashiro et al.[1] reported that (1) The spark ignition engine could run smoothly using acetone fuel. (2) Acetone has practically high octane number. So they could make the compression ratio high. (3) The CO concentration was about 1/10 of gasoline engine. However, NOx, HC, aldehyde, acetic acid were more than those of gasoline engine. Therefore the knowledge of elementary oxidation mechanism is demanded from the engineering side. Beside this, acetone is one of ketone and the oxidation must be studied from various sides. In this work we tried to observe the time histories of IR-emission and UV-absorption intensities according to the previous shock tube methods.[2, 3]

Acetone and PAN in the upper troposphere: impact on ozone production from aircraft emissions
Authors: Bruhl C.1; Poschl1 U.; Crutzen P.J.; Steil B.

Source: Atmospheric Environment, Volume 34, Number 23, 2000, pp. 3931-3938(8)

Publisher: Elsevier Science

The role of acetone and PAN in the chemistry of the upper troposphere has been investigated with a time-dependent photochemical box model. The results show that acetone strongly enhances aircraft-related ozone production, as exemplified in this study over North Atlantic during summer. For typical flight corridor conditions, the inclusion of about 1nmolmol-1 acetone more than doubles net ozone production by aircraft NO emissions and resolves discrepancies between observations and several global model predictions. The actual magnitude of the acetone-attributed enhancement of ozone production can, however, be reduced by PAN formation which acts as a sink for NOx (NO+NO2) and also lowers the OH/HO2 ratio.

Perhaps this is why its frowned upon to have so much acetone in fuels??? Between this article and the last, iut seems that acetone in fuel increases HC output, and output of acetone itself... Ground level NO and thus ozone is the result...

I guess this is why its not used as an oxygenate?

how much do you dilute the acetone with gas to make safe when you pour it down your tank? I'm gonna try this acetone stuff on me 91 pathfinder. I've owned this truck for 5 years and not once the MPG has gone higher than 15. even with FP, MMO and various other OTC gas treatment.

When you are about to fill up your tank, you pour in the right amount and then fill your tank like normal.

oilpan49 · Sep 23, 2005

how do you calculate just how much Acetone you need? For example, BlazerLT said "If you have a 15 gallon tank, then you need 4.5oz of Acetone" Just to ask, how do you calculate this? Thanks,,,AR

BlazerLT · Sep 23, 2005

3oz per 10 gallons exactly.

I have a 20 gallon tank, so I added 6 fl oz.

oilpan49 · Sep 23, 2005

wait a sec, so no matter if you have a 10 gallon tank or somewhere in between say a 16 gallon tank, it is still 3oz? I'm confused???????

No, you add 3 fl.oz per 10 gallons of gas.

So if you have a 20 gallon tank, you add 6 fl.oz and so on.

You get it?

oilpan49 · Sep 23, 2005

NO! This is ******* me off

All I want to know is how did you (BlazerLT) come up with 4.5oz of Acetone for a 15 gallon tank! What formula or whatever did you use to come up with this?

I already know the 3oz per 10gallon crap,,,AR

mdocod · Sep 23, 2005

for your first fullup on acetone, multiply 0.3 by the number of gallons your tank holds. That's how many ounces of acetone to add.

then from there on out.. at each fillup.. estimate how many gallons will be required to fill up, and multiply that by 0.3, add that number of ounces...

my first fillup, would be on a 22 gallon tank, I would add about 6.6oz to get started..

but then.. i usually fill up when i have about 4 gallons left in the tank(18 gallons to top off).. all fillups after the inicial, would take ~5.4oz acetone.

LarryL · Sep 23, 2005

Is everyone going to try 3oz/10 gal of gas so we can compare notes?

Now I understand!! Can I buy you a beer?

Sorry I didn't help, I didn't really understand what you were asking exactly.
