Putting Acetone in gas tank to increase fuel economy

[The_Head]

on my 1997 Yamaha YZF1000R and 1987 Acura Integra, and have seen about a 8-10% increase in fuel mileage. I haven't tried it for long enough to know if it was just a natural variation due to driving habits or conditions, or if the Acetone actually made a difference.

Hey guys wouldn't it be funny that the initial improvement is caused by plastics in the fuel disolving and burning in the engine adding to the fuel content and once the "loose" plastic is gone the effect is reduced!

I just came back from a trip out to Cape Cod and back to pick up a friend - the guy that drove me to the dealer to get my xB. I didn't run any acetone in this tank just the 3cc GP-7 but got 40.6 mpg today 190 miles. Will get used to the ScanGauge recalibration readings and then on the next tank put in 3oz per 10 gallons and the 3cc GP-7 and see what happens - by then I should be on a trip to Stamford CT - more highway.

Not even close to funny... seriously, would plastic add value to the fuel?

Plastic doesn't burn very well from my experience, and it also burns with lots of poisonous qualities.

So, yeah.

[JanGeo]

maybe it only disolves small molecules of the plastic...the acetone I had in the stp bottle turned a little yellow as it disolved the plastic - burned with a yellow blue flame when lit.

Another thing is my brother works on two stroke bikes and says the Torco oil doesn't burn - it comes out the exhost as oil - pours out from the muffler and pipes on bikes he repairs - so maybe it really helps to lubricate the top end really well - which would be a good thing.

I've completed 6 tanks of acetone added now, and when I stopped the acetone additions my engine would knock like crazy on a cold startup. So bad it even threw a code for the knock sensor. I reset the ECU and its perfectly normal now but I am thinking that acetone really does add octane? Anyone have any thoughts?

My results were a .53MPG gain over last years base fuel economy.
Having a tough time concluding one way or another on this.

December 04
22.25mpg
Total Precipitation: 3.25"
Average Temperature: 29.2ºF
Average humidity: 72%
Average windspeed: 4.2mph
Highest Temp: 58.7ºF
Lowest Temp: -2.4ºF

December 05
22.78mpg
Total Precipitation: 1.7"
Average Temperature: 26.6ºF
Average humidity: 74.6%
Average Windspeed: 3.1mph
Highest Temp: 41.5ºF
Lowest Temp: 5.8ºF


What would be awesome is if there was an easy way to automatically datalog exactly when the 0BD1 vehicle was in use during the month, and then just average up the weather values from those timeslots.

Well I didn't add any this tank filling and it seems to start a little harder - just turned 2000 miles on the xB yesterday on a trip to Cape Cod - I still get Calibrated ScanGauge 42.6mpg on my test ride around Ocean Drive 12 miles cold start but I am still using the Torco 3cc per 10 gallons. Of course I am getting some outragious MPG on this beast - way more than I expected. Hope a little Slick 50 engine treatment will bring it up a little more but that has to wait for the oil change at 3750 miles. After this tank - maybe I will fill up at half a tank I will add 3 oz and see what happens now that I know what to expect on the ScanGauge for Highway miles and local driving. FYI going more than 60mph starts to drop the mileage a little. Best is around 20-25mph in 5th or 4th gear at about 50-55 mpg - this engine is a m a z i n g!

Only thing I could think could affect the knocking is the gas not keeping the big and small hydrocarbons together and thus effectively modifying the octane (lower) as the smaller molecules ignite first and fast but the Torco is supposed to be taking care of that. Or maybe the fuel is not vaporizing as well and hitting the intake surfaces and heating more or washing away the lubrication.

Make sure to document well this slick50 stuff, I'm a skeptic but it'd be nice to not be anymore,

Will you use slick50 or xcel plus?

[JanGeo]

No need to document it I know it works - but the gas log will show how well it works. I have used it before and I have a bottle of the engine treatment already to go. Wallymart $11 pour and drive concentrate. Supposed to be good for 12,000 miles - not like in the old days when it was good for 50k. Xcel Plus may be next, problem is the small sizes are all out of stock on line and the shipping is now a killer for a lot of stuff. Tufoil is a repeat application so you have to keep putting it in for the moly and TPFE. It may pay for itself but getting the service guy at the dealer to leave out a quart may be a little tricky.

Saw this posting in pes_acetone group . . . interesting!

Subject: Acetone in B-12 Chemtool
Posted by: shinycars14

Today I saw it mentioned that Acetone is an ingredient in B-12 Chemtool, so I looked up some MSDS's at Berryman's (B12) website. I'm noticed that Acetone is in many of their products. I'm a layman probably like most people here, and read that B-12 is a "strong" product. For safety purposes at the low percentages we are using (2-3 oz to 1280 oz of fuel) I don't think it should be a problem. Also I believe the original Acetone website mentioned using 3-4 tanks with Acetone followed by 1 tank without Acetone. Here's a list of Berryman's products with the percentage of Acetone in each.
