Anyone seen this gas mileage idea???????

jekbrown, who is "the man" in your post?? what qualifications does "the man" have to make those claims?

... you just said, from "the man" and left it at that.... is "the man" a research physicist? How about a chemist?? How is his word easier to believe than the word of the guy who wrote the article?

the man = my dad. Hes was a research chemist for over 30 years and its safe to say he knows more about chemistry than pretty much everyone here. I don't know jack about that stuff, thats why I didn't say anything about the acetone idea, I just sent him the link and asked for his opinion on it. Anyway, the two factual errors he notes (acetone's 'special frequency' / gasoline surface tension) most prominently are the kinds of things that make me VERY suspect of this type of article. The author of it is just flat out wrong on those two technical aspects of his story and therefore one has to wonder what else is wrong.

you can add all the acetone to your tank you want, I really don't care. All I know is that my dad knows 9835784547 times more about this chit than I do and I'd rather not risk it when the benefits are small at best.

We must keep this thread alive :haha:



















Seriously , is there anyone that knows someone that could prove or disprove the things being argued about?

It sounds interesting , I would like to know what it would do to rubber gas lines
 
Why not just use metal gas lines? My lines are rubber up to the fuel pump, then metal from the pump to the block... but it would cost me maybe $20.00 to run metal all the way from the tank to the pump... I'm gonna try the acetone after I finish breaking in the engine... my mileage is still going up right now as far as I can tell... I went 242 miles on 22.6 gallons of gas for the first tank city and highway, for ~10.75 mpg... now I've already gone 242 miles, and I still have just over a quarter tank of gas left, so I think it should be getting around 11.25-12mpg on this second tank. I will start my tests after I go 2000 miles... so a couple weeks.
 
go for it, should make for interesting reading if nothing else. For the test to be worth anything, you'll have to do it over a period of time and the rig will always have to be atleast close to the same weight etc. Carrying extra passangers or what seems like not-to-much cargo could make a difference.

I tried it in my 1980 toy 4wd 20r with 300,000 plus miles. Still runs great. I was getting about 13 mpg so i started adding the acetone. After my second tank of "mixed" fuel I was getting 17 mpg. We ran this for 6 months and the decided to pull the head. I wanted to run it in my jimmy (8 mpg 355) so I thought I would check the valves in the toy. We took the head to a shop and had it checked. The shop said all the valves where fine. None of my pistons were burned. So I decided to try this in my Jimmy. I am now getting 12 mpg after running this through my 3rd tank in a row. So far I believe it and am happy with the results. And we just started this in my friends 97 dodge ram v6. I will let you guys know but in the two tanks we have done he went from 17 to 19 so that is a start. So we have tried a less than 2000 mile motor up to a 300,000+ motor. Carbed and injected. 4 , 6, and 8 cylinders. But these are just mt results. To each thier own. :D

Here are the results of someone who has done it. Do we have any reason to think that these results are not truthful? Not only that they are fairly comprehensive.
 
I am just thinking of all the rubber lines in a 4.3L V6 powered boat my uncle runs
We were just wondering what it does to the rubber lines that are required for vibration isolation in that fuel system :thinking:
 
Acetone does not affect natural rubber. We have a 5 gallon tank with a rubber line from it to a electric fuel pump and a plastic line from the fuel pump back to the tank. The 5 gallon tank is filled with about 3/4 87 octane and about 1/4 acetone. And we ran this for about a week straight before we tryed this in my toy. We changed out the fuel and acetone every day (we were bored and curious) and there was no damage to the plastic or rubber lines or the electric fuel pump (stock chevy tbi pump)
 
First i am not trying to be against this and may/will try in my 73. Question though.actone used in clean of paints etc.. says burns clean with blue flame. easy enough. You donot want breath exaust fumes anyway but how much worse are they with actone in them? I have read several times that some of the emisions go down. but on to the part that is really my question. MEK (methaetholketone) (not sure of spelling) used in cleaning of paint and other things burns nicely just like alcohol but you sure don't want to breath to much of the mek fumes when working with it. So what kind of harmful things are gave off from burning actone? I guess what i may be asking is what does the msds sheets say about this chemical?
 
Fuel lines would be the least of my worries... rtv, injector seals, etc.

What do you mean by natural rubber? Acetone has destructive characteristics when it comes to rubber... did you check anything else besides the fuel lines?

Was your toy carbed or FI? seems like acetone would eat the injector seals.

I will never do it because of the small benefits and potentially costly downsides but im interested to know more.
 
Im no expert on these type of rubbers but I wonder how 3 ounces per 10 gal. of gas could cause any damage to any part of an engine. straight acytone on the other hand ......
 
As far as breathing it goes...
You're not supposed to breath it in it's liquid form, so you're worried about what the burned fumes would be like. But if you think about it, you're not really supposed to huff gasoline in it's liquid form either, and none of us worry about gasoline fumes.
 
" Im no expert on these type of rubbers but I wonder how 3 ounces per 10 gal. of gas could cause any damage to any part of an engine. straight acytone on the other hand ......"


This is my thought exactly , there is such a small amount of acetone it should be diluted to the point of no ill effects
Now if it can be proven beneficial with no damage caused this would be a good thing for our pocket books :whistle:
I would still like to know if it has any corrosive effects on any part of the fuel system before I try it on my only DD
It looks like some people are going to try it so I hope it works out and they will keep us informed of any posative or negative effects
For those of you willing to try it I wish you the best of luck :thumb:
 
I am going to try it on my DD...right now I am finishing a tank of gas and will calculate my mileage, then I will fill up and add a few ounces of acetone.

I figure my DD is POS anyways with almost 200,000 miles, so not worried about ill effects. It is 89 Trooper, 4 Cyl, and I believe it has multi-port FI. So we'll see how it does, cause it needs some improvements in the mpg department :grin:

I got a 25% increase in fuel mileage not with anything other than going 65 instead of 75 on my last long highway trip I think I will try this acetone thing though

I agree YOu have to find the sweet spot. In my car I get 3 more mpg by going 65-70 rather then 80-85. It may take me a little longer but it will cost less! :)
 
I really doubt that putting a little acetone in the chemical soup they call Gasoline these days will cause any damage to anything.
Oil companies dump all kinds of aromatic HCs in gas. Since lead was banned Tolulene has been used to to raise the octaine rating. Gas can contain as much as 20% tolulene by law. Toluene will soften plastic and eat rubber. There also all those oxygenators like MTBE in gas, Benznes, ECT ECT.
I simply cant see how a small ammount of Acetone can cause any more damage that all the crap already in gas. Modern fuel systems are designed to be resistant to harsh chemicals they are exposed to. The only problem I can see with acetone may be if you have a fiberglass tank because acetone dissolves/softens epoxy resin.

So monday I dumped 6oz in my 30 gal tank. Prolly take 2 weeks for me to burn it out. Then I'll fill up again dump in 6 more oz and do a milage check after 2 tanks.
I usually get 15-16 MPG average in my K5 commuting to work and back and using it around town. I drive between 200-250 miles a week. So I'll post after I burn up some more soup.
Just wanted to add. That I really will be surprised to see any improvement in gas milage. But it sounds like an interesting experiment. I will drive my truck the same way I always do and see if there is any change for the better or worse.
 
Well, got some acetone from the hardware before going Trout fishing today. Whew! $5.00 a quart................have'ta find a cheaper source.

Added about five to eight (I guess) ounces to maybe 18 gallons. Drove 154 miles and I have more gas left than when I put 15 gallons in it. So...........I normally average 10 MPG going up in the mountains and back so, it looks like it did improve. Not sure how much but when I go to Tellico next week I'll have some in the tank and fill it up and check it upon refill. That will give a bit more accurate data.
