Some tips on putting

Some tips on putting acetone:

1. Using something like a graduated cylinder or test tube to pour acetone is a good idea.

2. Always be careful of spilling on your car paint - it will definitely corrode with the finish.

3. As much as possible, try putting acetone when your engine is still cold to prevent any premature evaporation.

Beginning Acetone Trials

Now that I've finished the tire pressure trials I'll be starting with acetone. I will be adding some soon (tonight or tomorrow) and will probably do a test run within a few days to see if there's any inital improvement. It has been reported that it takes up to three tanks to reach full effect, so I'll be conducting trials and tracking results as the acetone is taking effect.

I bought some science supplies to accurately measure the acetone. The large pipette is for getting precise amounts of acetone from the container to the test tube or specimen sample jar and possibly to inject the acetone right into the tank. The test tube has 0.5mL degradations for small accurate measurements, mostly for when topping off and I only need to add a minute amount to keep the ratio. The larger specimen jar is for adding enough acetone to mix with a full tank of gas. I will be using 1.5oz acetone per 10 gallons of gas. That is roughly 44.4mL.

I hope there's more to write about this experiment than the tire pressure experiment.

I didn't see anywhere on the can that says it's 100% pure acetone, but I'm guessing it's good stuff. I got it for under $5 at Wal-Mart. This is enough to mix with 213 gallons of gas or about 7,500 miles for my car.

Just read a nice piece of information concerning acetone and how long it takes to take effect. Apparently the reason it takes a few tanks to work at its full potential is because the ECU is relearning the mixture. Disconnecting the battery (negative lead) for a few minutes will reset the ECU and it will immediately start learning the new mix next start-up. I plan on doing this before my acetone trials. I will drive around for about a day so the ECU can relearn with acetone, then I will conduct the first trial. Just thought I'd mention this to those participating. Hopefully it will speed up the results.

Good call on resetting the ECU.

I plan on testing acetone on the trip down to vegas. I will drive to vegas without acetone (nearly 400 miles) and then drive back with acetone. There is a problem with the fact that I'll be going downhill one way, and uphill another way. Perhaps I'll monitor RPMs as well to determine a ratio and figure it out that way.

youre using 6oz/10gal

youre using 6oz/10gal gasoline?

if you only use 2 oz/10 gal, then itll last you 640 gallons.

No. If you do the math you

No. If you do the math right you get:

(32 oz. / 1.5 oz.) * 10 gallons = 213 gallons

Resetting

This is how I reset my ECU:

Just pulled that fuse you don't see there.

On the way down to vegas

On the way down to vegas from SLC I had 42mpg. This was without acetone, and with the A/C on most of the time.

On the way back to Salt Lake City my mpg was 37. This is with acetone and without A/C.

At first glance it looks like acetone hurt gas mileage. It may have, but I'm not totally convinced. This is mainly b/c the trip down to vegas is a very slight decline. The trip back to Salt lake City is a very slight incline. On both trips my target speed was 65mph at 3000rpm.

For some comparison, my last trip from Vegas to Salt Lake City yielded 33 miles per gallon. Since then my oil has switched to synthetic and my transmission fluid was changed, so too many variables have been introduced to determine if my mileage boost was due to acetone or not.

Looks like I'll have to plan a second trip (this time, somewhere flat) to determine the effects.

Wendover, NV seems to be the most logical choice.

On my first tank with 1 oz

On my first tank with 1 oz per 10 gallons I went up from my baseline of 38.5 to 41.7, so that's good, I'll run another tank to be sure, and then begin increasing stuff bit by bit.
