I read an article (Article can be found here (http://pesn.com/2005/03/17/6900069_Acetone/)) that said adding acetone to gasoline and diesel can increase fuel mileage up to 35% without any detrimental effects. Is anyone doing this? Pros or cons?

This place (http://peswiki.com/index.php/Directory:Acetone_Additive:FAQ#Q._What_about_diese l_engines.3F) says it should be fine in diesels, albeit at smaller ratios than in gasoline engines (i.e., less than 3 oz per 10 gallons). I don't want to gamle with a $40k+ truck.

On the contrary, this guy (http://peswiki.com/index.php/Directory:Acetone:Gerry) noted a reduction in mileage on his 02 7.3L PS. That seems contrary to what the gas burners are noting. On the flip side, it didn't damage his PS and he noted smoother power (but less smoke, which may be a bad thing ;)). Of course, he probably was getting into the accelerator too much (you know, like when you first get a chip).

Anyone have any experience with it? :cool:

Okay this is the fourth forum I read where this horse sh*t has popped up. We argued it back and forth on a mercedes forum a few weeks ago. The discussion can be found here (http://www.mercedesshop.com/shopforum/showthread.php3?t=118589&highlight=acetone). One guy actually tried it and got all excited after his first tank showed a slight increase in mileage, but then his next couple tanks were back to limits of error for normal mileage. If you want to send that crap through your injection system, be my guest, but I surely wouldn't put it through mine.

Nothing you can dump into your tank is going to increase fuel mileage 35%. As soon as someone posts a claim like that BEWARE. There is no magic formula.

As far as dumping solvent into my $11,000 engine? Perhaps if I'm going to trade it in at the end of the month.

It's a vast right wing conspiracy of the acetone manufacturers ):h

If something seems too good to be true, it probably is.

I can help you with a good experimental design - on YOUR truck :D

This is about the same kind of thing as the magnets and whatnot you clamp on the fuel line that supposedly yield the same results.

"Acetone drastically reduces the surface tension. Most fuel molecules are sluggish with respect to their natural frequency. Acetone has an inherent molecular vibration that "stirs up" the fuel molecules, to break the surface tension. This results in a more complete vaporization with other factors remaining the same. More complete vaporization means less wasted fuel, hence the increased gas mileage from the increased thermal efficiency."

While it actually may improve mileage (I'd have to have some real data to tell), the explanation given above is complete BS.....and actually makes us geeks laugh out loud ):h

It would be simple to test. Use a dyno. If in fact mileage improves, it means that there is more energy released from the fuel. More energy released means more HP. 35% mileage would equal 35% more HP. Just think! 2 oz of acetone could behave like a 85rwhp tuner! You'd certainly feel it. It would eliminate our bursting issues and fuel supply issues as we could ramp up the HP 35% using the same fuel flow that causes problems. Think 650+ rwhp on #2 with Acetone!

My guess is this is how the guys are running 11's in these trucks. But be aware that 85rwhp might limp your Allison, so be careful.

I particularly liked the molecular vibration line. I work with Near and Mid-Infrared instruments, which use the principle of molecular vibration. My boss and I got a good laugh out of it.

If you want to speed up your fuel molecules, maybe you need to put some methamphetamine in your fuel tank. That'll get them going.

All you guys are cracking me up:D :funnypost's

I highly doubt I'll give acetone a shot. It's that "unknown" factor that scares the bejesus out of me. I'm not too concerned about seals and what not deteriorating because of the incredibly low ratio of acetone (I think 2 oz per 10 gals in somewhere around 1:1000).

I can understand seeing some modest gains. But like the rest of you guys, there ain't no d@mn way people are going to see 35% increases without the major media and manufacturers picking up on the schtick and it becoming the latest greatest innovation in engine dynamics. :D

And they are talking it up here with results BIG time...

dont spill it on the paint

If you want to get 35% better mileage. Get a tank that is 35% bigger, fill it up, but don't count the extra amount of diesel when you do the math :eek:

My guess is this is how the guys are running 11's in these trucks. But be aware that 85rwhp might limp your Allison, so be careful.
I can't believe that u let out the secret power adder for the fast boys.

NOW everyone knows how your vette got to run so good.

WE also see how u won those pulls.

I guess I'll stick w/ my 10% nitromethane mix in my diesel :ro)

someone puta little acetone in their ridding lawn mower and see if you can mow the lawn 35% faster :D. That will be a good prooving ground for this little "experiment".

:grd:

Yeah that dillhole changed fuel octane, fuel brand,,engine tune,driving style and other items. how does he know if acetone casued an increase in milage?

Acetone can increase octane and clean your fuel system. So any gain would be from the increase in octane and the fuel system cleaning.

Acetone in a diesel would lower cetane.

35% more power won't get you 35% better fuel economy. if that is the case the tuners would get better mileage. both ways on that ISSUE were BS.

propane helps a lot on mileage if you can keep your foot out of the power I know guys that are getting 25mpg on trips with the dmax.

35% more power per gallon will. You will use 35% less fuel to acheive the same goal.

Well, FWIW, I read the same article, and since I hand-calc my mileage, and I get a shock every time I see the cost of a tank of fuel, I tried it.http://www.dieselplace.com/forum/images/smilies/eek.gif.. 4 tanks with acetone in the 3oz.-to 6oz.-per 20 gal range. No noticable difference in mpg or power. However, in defense of actone being a surfactant, I did notice that when filling up, I could only get about .1 or .2 gal more to go in after the the pump shut off. Usually, it takes at least another gal or so to fill up the neck. So it does seem to reduce the foaming of the fuel while you're filling. Other than that, engine had a little more timing rattle, but that's about it.
I haven't tried it in a gasser.
You guys with lift pump/return foaming problems might want to experiment with the pump in bucket to see if it really does knock down the foam...

Another additive I experimented with was GTA- it supposedly alters the molecular structure of the fuel, causing it to have "visco-elastic" properties thus making it combust more completely, blah blah etc.. It did seem to add maybe .5 mpg avg, and the engine ran a little smoother and quieter. But, for some reason, I didn't suddenly have power to light the tires off in fifth gear... Oh well...

Google "GTA Fuel Enhancer" if you want to read more about it...

I bought a weasel farm so that I could add precisely 3 ounces of weasel piss to each gallon of diesel pumped into my truck.

Mileage is up 67.2% and I gained a useable 89.6 RWHP.

My exhaust does smell odd.

Thanks for the "real-world" report!

I bet it does.:eek:

LOL...so I'm a smart-ass, what can I say?

I just get a big kick out of all the snake oil/weasel piss people dump in their tanks to get better mileage.

All the miracle products designed to clamp on to fuel lines, etc. provide me with the same entertainment. But hey, it's your truck, so do what you wish with it. As for me, fuel additives from Stanadyne or Power Service are exotic enough.

One day when I have enough money to blow. I'm going to get all the snake oils out and mix-em up, enough to fill the tank anyway, and I should, and I "repeat" should, get around 100 mpg and have at least 800 hp. Of course this will be MY results, ours may vary.:D

John

Let me know when you start the project. I'll be glad to donate a few ounces of weasel piss because it's pretty hard to come by.

...Another additive I experimented with was GTA- it supposedly alters the molecular structure of the fuel, causing it to have "visco-elastic" properties thus making it combust more completely, blah blah etc...
"Visco-elastic" properties?!? You have to be kidding. Those people that advertise sh*t like that should all be drug out in the street and shot. If they survive, they should be shot again.

Many lay people have a bad enough view of scientists and science they don't understand, and then you have idiots like that using big, technical, scientific terms to sell crap that doesn't work. It just makes people more distrustful of science. Ugh, it just ticks me off...:rant:

35% more power per gallon will. You will use 35% less fuel to acheive the same goal.
The problem with your theary is, you don't use the same amount of fuel to acheive the extra power. Sure more BTU per gallon would give better mileage, but that just don't happen, More power comes from more air, and more fuel.

35% more power per gallon will. You will use 35% less fuel to acheive the same goal.
You guys are funny! HP cannot be calculated per gallon.
HP = Torque(lbft)*Speed(rpm)/5252

To get 35 % more power from the same amount of fuel the fuel must be burned far mor efficient than adding propane - far more efficient than 100 %....:exactly:

You know I don't necessarily agree with McRat's analysis of 35% more mileage equalling 35% more hp, but I can't think of any good argument against it. So I would like to see this discussed further.

Mahalkita, in the equation you used, how is torque created?

If it takes 60rwhp to move a truck 70mph down the road, and you can do it with 35% less fuel, it stands reason that your fuel is making more power per amount injected, assuming no other changes.

Inject an additional 35% more fuel, and you will be at your previous usage, but you will have about 80rwhp instead.

I know on the surface your logic sounds reasonable, but I just don't think it is quite that simple. That is why I want to see further discussion, hence my question to Mahalkita.

I'm just a chemist and not an engineer (although I technically came to college as a chem e-that only lasted 2 weeks), so discussions of power, torque, etc. are just on the edge of my understanding.

I get 35 % better mileage by letting someone else drive my truck

I am too cheap for a weasel farm so what I do is drink half a fifth of 151 and than urinate in the tank, I cant say that I have seen an increase in fuel milage or horse power but man does the ride become interesting a little blurry and it is harder to drive with one eye shut, I also have to put 2 asprin in the tank the day after or she really has a hard time starting. ):h I am think n about upgrading to everclear in the near future, I figure with the added 20% alcohol the ride should be at least 40% more entertaining. Off to do some R & D:muahaha:

Hmmm...would that be called "piss injection"?

Wonder if SD makes a manifold for that...

If he starts making one, it should be called at SPIM. That's short for Super Piss Injection Manifold.):h

LMAO @ jnieberlein! Too funny man!

It's a little off topic, but do you guys remember that movie Down Periscope? I love it when the ol' boy down in the engine room of the submarine says something like, "Ah put this here whiskey in them tanks and she gains 10 % power!"

Hey Coyote,

Exactly how do you collect the weasel piss???

Call me gullible, but I actually tried it. But not in my Dmax. I tried it in a little Plymouth Neon. I gave it a chance for 2 or 3 tanks and it actually decreased my mileage. It went from 27- 28 mpg to about 23.

Hey Coyote,

VERY CAREFULLY, but it easier than collecting from a grizzly:eek: :eek:
