15-35% mileage increase

[evoq007]

well those results are kinda depressing.

[bmxking5]

Yeah^^^^

Gerald, that's pretty decent mileage though considering what's been done to your rig.

 

[huskyfan23]

Hm. Maybe it takes the full tank? That sucks.

 

[Albino 94LTD]

I'm assuming by your edit that you refilled the tank between trips??

 

[Interstate]

Have you testers done a fluid weight test? Like does the acetone actually mix with the gasoline or does it sit somewhere at the top/bottom?

Test Results: 1999 SOHC - (stock except for Gibson catback exhaust). 4.88 gears, 35" tires, 60 mph cruise control.

4/07/05 wind NNE @ 15 - 20mph
roundtrip: Greenvlle SC > Newbury SC and back.
100.4 miles, 5.5 gals, 18.3mpg

Acetone added same day@ 2.5 oz / 21 gal tank:
identical results; same day, same highway, same roundtrip, same readings.
102.2 mles, 5.6 gals, 18.3 mpg

I'm unemployed but I just spent $30 for gasoline and acetone today in order be able to give this info to our members... hope it helps you all

Man those numbers are depressing numbers. I get 17 city and 21 highway without acetone, and 21/25 with acetone. You want to add the acetone when you have about 1/4 tank of a tank left then fill it up so the acetone has a chance to mix with the gas. Also with it being OBDII you may need to go through a few tanks of gas before you start getting any benefits, this is what I had to do. I found Chevron to work the best alo.

I'm going to call BS on this.

But I'll wait and see.

In case it wasn't clear.

Thanks

Thanks for the test results, GJarrett. Although I admit it is kind of depressing, I kind of expected that would be the case...

Personally, I think a good injector cleaner will do better than acetone in terms of MPG in the long run. As far as for acetone not mixing with the fuel, I think it would mix inside the tank by itself after a few turns and potholes pretty quickly.

 

[huskyfan23]

I think being OBDII might have something to do with it.

 

[Albino 94LTD]

I'm wrong, at least for the first tank

I think being OBDII might have something to do with it.

Nope, at least not yet.

My first tank.

214.5 miles 15.009 gal 14.3mpg, all city driving.

Same as without Acetone, maybe even a little less than before.

Moving average per GPS 27.6 mph
Arco 91 octane, Apten (Brian Herron) tune for my mod's listed below
tire pressure 31.5 front 30.5 rear 3.73 gears w/31x10.5 tires.

I will continue to test and try different ratios.

 

[techieman33]

this sucks, I was hoping it would make a difference, though we have still yet to hear from aldive.

 

[GJarrett]

Yep I topped it back off again to mix the acetone up into the gasoline.

The comments may be true about the ODBII and/or computer needing a couple of tanks to reset for the mixture before seeing results, but I'm not going to continue the test. Someone else can take the baton and keep going

As for my mileage, I'm actually fairly happy with that. New, my vehicle was rated for 19 hwy EPA. Adding lift and large tires will drop mileage about 10% because of increased rolling and wind resistance. I've got nearly 160k miles on this and beat the heck out of it and it still almost gets the stock EPA rated highway mileage even in the hilly terrain where I live. I went to synthetics and regeared which is probably why I'm still so close to the original mileage rating. Going faster than 60mph my mileage starts to drop very fast because of the added wind resistance of my lift, tires, safari rack, etc - at 70 mph I probably don't get any better than 15m[g.

 

[NICE59FORDF100]

hmm, something i figured: for those of you that are skeptical (trust me, i am too when my sister added fuel injector cleaner, it caused for new piston seals) think of this: you can always just try one or two tanks of gas with this. Its not like your obligated for the rest of your life to add acetone to your fuel, if your worried about the lines and such. try it once, and if no results, then dont add any more, lol. when i get to about 1/4 of a tank, ill add three oz, and fill up, and report back. on average, i get 15 (300 miles to one tank) peace yall!

 

[james t]

update tank 1

Well, i just ran out the first tank. Here are the results-

avg. MPG before acetone (averaged over the past 6 months, basically all city/no highway)
12.1mpg

avg. MPG this tank w/4 oz. of acetone
11.4mpg

I would like to add that on this tank i had to pull an 18ft. flatbed trailer about 50 miles. The trailer alone is home-made and weighs around 3000lbs. This was 50 miles of interstate with my foot basically on the floor. This trip ruined my test.

Overall, i still dont think acetone does anything, but will continue the tests for at least a few more tanks.

This is an interresting topic, and something that's difficult to just write off. Every time gas prices go up we see new ideas about saving gas, but the thing that's different about this one is that nobody seems to be selling anything. The general idea is to get some Acetone from the hardware store and add it to your gas -- what would be the motivation for someone to make that up? I really doubt Home Depot is behind this hoping to move some Acetone off their shelves....

The fact that our vehicles have a catalytic converter proves that gasoline does not combust completely under normal driving circumstances. If adding Acetone can help produce a more complete burn then there is definately something to gain.

The whole debate may be over as soon as Aldive checks in -- he's certainly qualified to put the theory to test.

 

[Albino 94LTD]

I'm not giving up yet.

I have 3 tunes, at least 2 driving types (city and highway) and variable ratios of Acetone/Gasoline to try.

One tank doesn't provide enough proof, or lack of, that this will or won't actually reap benefits.

Besides, I have a brand new gallon of Actenone on the shelf and I don't need all of it for cleaning paintbrushes

I am going to test the acetone/gasoline blend this coming Wednesday on a 510 mile run to Atlanta.

I am going to use the 2 fl oz/10 gal gas blend. The fuel will be Amoco 89 octane. The computer tune will be one of Doug’s ( http://www.bamachips.com/ ) made for my truck on 89 gas. The acetone used is Klean Strip Acetone (http://www.nazdar.com/MSDS/distributed/wmbarr/Klean%20Strip%20Acetone%20(GAC18).pdf [ 100% pure ] ); it cost $4.50/qt at Home Depot. I have previous data on the mileage with this tune; best long run mileage was 28.4 MPG ( http://www.explorerforum.com/forums/showthread.php?t=128827&highlight=computer+tune ). The speed and miles traveled will be GPS determined ( Garmin Street Pilot 2620 ).

The data will be reported when I return to Florida the following week after a dyno session with Doug in Birmingham on Saturday.

The trip to Atlanta - 512 miles MPG-30.1 Avg speed 67.8 MPH
The return trip = 534 miles MPG 29,96 Avg speeed 72.1 MPH

Average MPG using this tune and 89 gas before this evaluation 28.5 MPG.

 

[NICE59FORDF100]

so aldive, your gas milage went up 1.5 mpg's? id say thats pretty good for only putting in a couple of onces of fluid. i think the trend with the acetone is on longer, straight trips, its increses milage, but on shorter, normal city driving, i think it doenst help. another thing i didnt think of: what id you need to go ahead and reset the ECU when doin this, so that way, the computer will learn the new feul mixture.....i mean, that might be why some have seen no/same results? just an idea. by the way, im doin this tonight, so ya, i will be accepting donations for a new crate 351 when my motor implodes

 

[Jefe]

another thing i didnt think of: what id you need to go ahead and reset the ECU when doin this, so that way, the computer will learn the new feul mixture.

Don't know why I'm even bothering to read this thread , but if you're going to reset the ECU before the test with acetone, then you also need to reset the ECU before the base test.

 

[alexefron]

plus you would have to give the computer some time to learn the new fuel, and timing curves, and then refill the tank with each type of gas, and test it...
