Have you had results with acetone.
 

Anyone who has used acetone mixture and has had success please list mixture, make and age of car.

Can't remember my mixture, pretty sure it was the suggested ratio. 1992 V6 auto Camry. I also had my coolant boil over for the first and only time.

results
 

I couldn't tell. The only difference was that it made my idle speed lower. No harm.

Did you stop using it then? Also what kind of increase did you see before and after.

Yup, it was on a run up the Cajon pass, after that I refilled coolant and stoped using acetone, no more trouble for the rest of the summer. I saw a difference of 2-3mpg over my best trip mpg (~34mpg) up to that point. The trip was hwy with the same distance, same traffic, same weather, and 55mph cruise control. The only problem was I didn't get in enough runs to determine if it was a glitch or if the acetone actually doing something, I also had ~5 miles our of 50 that were street, which could've influenced the results. I've heard it leans out the engine, but that's just heresay until I brush up on my chem... You wouldn't happen to know if your oxygen sensor is titanium dioxide, or zirconium dioxide?

No I don't. I think it's probably zirconium.

3 oz per 10 G...'87 300ZX na...around a 20% gain...but some part of this was due to easier driving.

It was inconclusive for me. without a scangauge It makes results very difficult.

I used it for a little more than a month last year which translates into about a 1000 miles and didn't see any change in FE before, during or after using the stuff.

It matters that you got some good acetone and that you drive to save otherwise you dont' get an improvement - it allows you to get even better gas mileage with it that without it - it doesn't give you better gas mileage it allows you to get better mileage. I couldn't get past 46mpg until I used it now I get 50-55mpg.

Well I have lots left over. I will use it when I start driving 90-100% highway in a few days.

I'm calling bull on that one!

Hey I get 32mpg if I drive 80 on the highway with acetone - it doesn't help when you are burning it at 2.5 gallons an hour - it helps when you are burning 0.3 to 0.5 gallons per hour by making the injectors work better at low volume operation when they usually don't atomize the fuel properly.

So how much would you quantify to easier driving and have you stopped using it since driving easier to see what increase you had?

I use it for all three vehicles.

97 Ford F150 - 3 oz/10 gal
92 Saturn SL1 - Currently testing 3 oz/10 gal
03 Honda Odyssey - 2 oz/ 10 gal

All get about a 10% increase of fuel economy. I've started using it last year and have run through 2 1/2 gallons of it so far. Anyone who says it will hurt your engine I think either hasn't tried it or is listening to someone else. My truck has used most of the two gallons as I drove it the most until I got the Saturn. The wife drives the Honda so I put in acetone about every other tankful when I get around to it. All get a noticable increase in power as well. In my truck feels the most noticable, and the exhaust pipe no longer has any black soot in it. I wouldn't drive without it even if it didn't increase my mileage because the increase in power is that noticable to me.

This goes against the theory of acetone. If it does indeed aid vaporization so greatly it won't matter how you drive, because your fuel will get "burnt more completely" anyway.

I thought that the fuel pump provided the same amount of fuel pressure to the injectors no matter what the engine rpm is. The only difference would be the amount of pulsing that is requried to meet the fuel demand. Since the pressure is constant the amount of atomization would be the same, just less pulses.

Give a man a fish...and he will eat for a day. Teach a man to fish...and he will tell fish stories for the rest of his life!:D

Yeah and the duration of the injector spray is varied to vary the amount of fuel injected but the spray during valve opening and closing during short pulses is not as good as when they run wide open. There is also fuel flow variations when the flow changes which effectively varies the pressure slightly.

Saw an intesting bit of info on Synlube site today apparently 1 gallon of gas requires 10,000 gallons of air to burn 14.7 to 1 ratio - that translates to a lot of air!

I ran acetone for 4 months straight 3oz/10 gal ratio. My mpg did increase over 3 tanks 2-3mpg. I used up the small amount I had and never bothered getting any more after I ran out. The mpg never went down from not using it over the next 10 or so tanks of gas. I would say the acetone is a good injector and fuel system cleaner so it can help clean out the system and get it running properly. But once the fuel system is clean it doesn't help improve mileage over that. So I plan on picking up another quart of acetone and using it occasionally to help keep the fuel system clean but other than that I don't see it helping much.

I gotta disagree, and state the opposite. It allows those who P&G with hard throttling up to speed to see even greater results. But you have to have a newer o2 to go with its use(less than 30k). And anyone who has a heavy foot will also see better fuel mileage.

that it does. and sometimes i think people get the placebo effect:p

i run half a can of seafoam thru the engine and the rest in the gas every oil change:thumbup:

I use 3 parts acetone, 1 part xylene, and 1 part lucas oil upper cylinder lubricant. I saw a 12% gain in the summer but little or no gain in the winter. I add 3 ozs of mixture to 10 gallons of gas. Works best in warmer conditions. Also really cleans out injectors and fuel system. My 2004 toyota matrix has 280, 000 miles and runs like it did at 60k.

2 Test vehicles on round 1300 mile round trip. 1 2004 Toyota Camry V-6, 1 2001 Toyota Solara V-6. Both cars driven in tandem. Average highway speed 78 MPH using cruise control as often as practical. On the trip away from home the camry averaged 29.9 mpg, the Solara averaged 24 mpg. Both cars used 93 octane round trip. On the way home both vehicles used 3 oz acetone per 10 gal gasoline. The mileage home was 33.5 MPG camry, 27 MPG Solara. We only bought fuel at name brand gas stations which are less likely to already contain tons of oxygenates etc. in their fuel.

Our 98 explorer gets about 2 mpg increase as well.

my 88 cressida had no appreciable results trend. I tried with everywhere from .5-4 oz/g

My Jeep showed no change in FE, just a better idle. I tried 2oz/10g and 4oz/10g

My '93 Mazda MX-3 GS's both get about 3 more mpg with 2 3/4 oz. Acetone per 10 gal. gas. The one with a 1.8L V6 has had this added for over 2 years, and when I forget, or can't, it goes back down 3 mpg. the one with a 2.5L high compression (210 psi) engine got 30 mpg on 89 octane (1 mpg more than good 92 octane).

I've tried acetone in both Wile-E and Marvin... I was doing alternate tanks on and off, ABABA.... on Wile-E I was getting some variation, but it was hard to tell if it was significant, my high tanks seemed to be a little higher and my lows didn't seem as low. On Marvin, I was getting more of a definite gain, 1-2mpg better. Which is a bigger gain around the 20mpg level than the 30mpg level. I kinda got out of using it because it was too much of a PITA for marginal gain on Wile-E and I had Marvin laid up..... then haven't gone back to it on Marvin, since his rings aren't the tightest in the world any more and began to be worried about it affecting the oil. So it seemed to do a best of 10% or so on Marvin, but Wile-E's figures seemed to suggest it was getting 5% or less.

I understand the comment about "driving to save" with it though. Wile-E, one has to drive fairly hard anyway, due to limited power, and speed required to merge safely, Marvin has power to spare, but you have to spare it to save gas. In both vehicles, it subjectively ran smoother and more responsively, when that happens one does have to be careful not to "have fun" and just accelerate excessively for the hell of it. Meaning that as with some other gas saving tips, it's also a potential performance gainer, and it works as long as you use it wisely and don't succumb to the power of the dark side.... even if they have cookies.

I tried it in my 97 F250HD with no real increase in mpg. I tried various mixes and logged them all in excel to try to narrow down what mix worked best. I just gave it up cause I got tired of adding mixes to the tank. I think ford's EEC-IV cpu fights any mpg increase I try. The only guaranteed (fuel related) mpg boost that works for me is using 100% gasoline and not 10% ethanol. Thats worth 2 to 3 mpg in my truck.

Yeah, same core ECU in Wile-E the Escort there. If I don't pick up MPG when the modded head goes back on it, then I'll start messing around with biasing the MAF a little to see if it's foolable.

I should mention that I cruise at about 70 mph, and don't employ driving techniques as faithfully as most people here. Maybe Acetone makes more of a difference for us less hypermile minded. If I were more patient, I'm sure I could push my 30 mpg to 35 or more.

Vehicles used:
1995 D-2500 Slt Laramie
1988 Bmw 325ic

I don't think it does, the bmw's mpg got worse, the truck seemed to improve but it wasn't conclusive... Also don't forget to figure in the price of acetone, I paid nearly $10 a gallon for it so 3 ounces per 10 gallons adds 23.44 cents to every gallon!
Even if I see an improvement and at today's prices that adds 7% to the price of fuel, then I need to figure in my time so for myself to see an improvement that pays off I would have to see at least 15% improvement and I can honestly say I don't think I saw 10% if I saw that.

Adding a tonneau cover was more expensive initially but doing that gave me some figures to compare... My last tank's mpg on the truck was 11.88 compared to the usual 10.0 - 10.5 - 10.8 mpg, now I never saw over 11 with acetone.

And it was good acetone, 99% stuff from Sally's Beauty supply.

Yes but now it's the driving that's saving the fuel, not the acetone.

Try driving like that without acetone :)

Wow that's almost $30 a gallon, shoot no, mine's way cheaper when there's 3.785 liters in one gallon it costs me 10 bucks for almost 4 liters and still it's not cheaper in terms of economy.

This is the problem: dumping 3 ounces of that Canadian acetone is costing another 70 cents, say times 10 gallons of fuel that's 30 ounces so 7 dollars.

Then we have to add all the rest of the additives and it wouldn't surprise me if you're not dumping an extra $20 into your tank in this fashion.

So the question I keep throwing around is, does this $20 pay off in the savings, or wouldn't it be as cheap to just put another $20 worth of fuel in the tank and be done with it?

Lets assume 40mpg straight fuel, 10 gallons, $5 a gallon.
Hmmm that's $50 but here we add another $20 so we get 14 gallons x 40 =
560 miles for $70

So then we take the other formula, 10 gallons, 50 mpg, $50 for fuel + $20 for additives, I'll give you the mileage here for the extra ounces of additives which is roughly a quart so 10.25 x 50 =
512.5 miles for $70

What do we want, 40mpg, pay $70 and go 560 miles...
Or 50mpg, pay $70 and only go 512.5 miles...

That's the whole point of the exercise is fuel economy.

Miles per gallon is just that, but Fuel economy is miles for the dollar, and if it costs more to go the same distance then it is not feasible economically speaking.

I did want to add, one-time expenses are not calculated the exact same way and in that sense a one-time expense can be a lot higher but it also has to be figured (over the expected life of the car vs. Blue book value and maybe one or two other things).

So unfortunately we have to do the math, or it doesn't work.

There may have been a slight increase when I tried it, but it could have been to other variables. Even if, it wasn't enough to warrant the cost and hassle.

On the other hand, the v-6's in the Ranger are prone to pinginess, and I've noticed it on the steep hills. I'll try in again during hotter weather to see how it works as an octane booster. I also plan on trying a higher octane sometime during the summer.

I use to use acetone in a 96 eagle talon tsi. No real difference in mpg but one of the rubber fuel lines did start leaking after a year.

Check your math . . . it adds 2.344 cents per gallon . . . 23.44 cents per TEN gallons! Now it is not so bad HUH? Takes about a 1% mileage improvement to break even.

And driving 80 MPH without Acetone would produce a lower mileage but there is no place to drive that fast around here. THere are some xB owners that do drive that fast and get in the high TEENS for MPG.

Hey I had a friend with a Professional discount get me a gallon at Sally's - looking forward to the next filling to add some of the new Acetone to see if it works any better than the Ace brand I have been using.

Used home center acetone for most of a year in the last car. Nothing out of the ordinary. But the car really never reacted to anything. Got a new car, and the first tank with acetone dropped from 12.3 to 10.7. Not much of an increase to me. I will drive this current tank down, and maybe try it again. I was actually being nice to the car 98% of the time. Only hit boost twice.

my days of using acetone are likely numbered. E10 finally has made its way to florida. my last real jump in FE using it was just before the "contains up to 10% ethanol" sign was placed at my favorite filling station.

it must be true that ethanol negates the affects of acetone. that's what i'm experiencing anyway.

It is said...and is whispered in the back alleys...that isopropyl at about the same % as acetone works even with the ethanol. I tried 4-5 oz of 91% (9% water) and saw no gain...but had other stuff happening...did have more power though. Need to use a top oil though to protect the fuel pump.

I'd use 2-3 oz per 10 G if I tried it again. I'd probably more likely try 24 oz cheap canola oil and 3 oz iso per 10 G. Some claim good mpg gains and not a lot of smoke...maybe cause the canola acts as much as a fuel as it does a lube?

note: this is what I'd try...your intentions may be different...:cool:
