Here's something new to ponder.

http://pesn.com/2005/03/17/6900069_Acetone/ I have no comment.

So has anyone here tried this? It sounds very tempting.

Yup :!:

Its been tried. And in fairness it does work but the 30% claims on that site are very optimistic. ;) IMO 1/10th is more realistic (YMMV :!: ) And they do "down play" the corrsive issues that acetone has on plactic parts. Of which there are many in most car's fuel systems.

There was an Insighter that was posting here a year ( :?: ) or so ago and was in the "clinical" trial stage. But he just slowly faded away... Hmmm.

DO NOT ADD ACETONE TO YOUR CAR!!!!!!

This claim is not new and comes back around like a bad chain email every so often. It has not been proven to work either way. This subject has come up both here and on the Prius forums with no resolve other than - would you take the chance to permantly damage your prized Insight for a remote possibility of couple extra MPG's?

I've read through the sites where the dude claims to have used Acetone to all his vehicles throughout the years, gaining MP, gaining MPG, and minimal wear on parts. But those were old school vehicles, made of old-school iron and steel. He claims they've gone past 200,000 miles thanks to this dangerous chemical. But with proper care, they would have gone that distance anyway.

Our fuel systems are advanced and designed for maximum efficiency.

Do not risk your car. If it's too good to be true.......

Ok Richard :!: :shock:

You took the straight and narrow path on this one. :p

Acetone is a part of many fuel injector cleaner addatives. _AND_ if your in this somewhat "unusual" catagory then it will "work". _BUT_ once you've reached maximum "cleaning" potential the effect will reduce to the "background noise" level of 3-4 MPG (in an Insight anyways ;) )

So it _does_ "improve" MPG in limited, temporary and specific ways. ;)

Its the rest of the story that gets twisted :!: :p

HTH! :)

Acetone?

Mind you , I havn't read the whole article yet, but 2 oz. per 10 gal. is not much.
I don't buy the 20% MPG claim either, but what reference do you have rebuffing these crazy claims?
I put more ethanol and isopropl in my fuel in the winter than that.
Which parts would get harmed and how?

Easy question to ask. _Much_ harder to answer. But if you've spent any time using acetone for its other well "accepted" uses that you'd know the plastic and "melting" problems. And it can happen by degree (slower reaction or more limited depending on the specifics).

Simply the manufacturers did not design the fuel system to be exposed to just any off-the-shelf chemical. Particularly one as reactive as acetone.

Guess you'll have to prove this one to yourself :?:

Okay, I may have been a little hasty and to the point on my last post - my apologies for that.

Personally, I have nothing against trying something new. With all the fuel enhancements and cleaners on the market today, and since also acetone has been a myth since around the 60's, you'd have thought that this would have been a proven, marketable solution by now. Why is it still considered a "snake oil".

I've given thought to trying it...really. But when I weigh up how much i cherish my little exotic car, compared to what would happen with costly repairs, I had to shy away from it. I'll leave it to the experts with the dyno gear, treadmills, and chemical analysts.

Please, if anyone is actually doing this - please post your results!!!! Also, I must warn you, even if the initial results look promising, look ahead about 3 to 5 years to whether or not your internals are effected after many years of use.

John - please forgive my hastiness!!!

Snake Oil

Which internal parts might be affected in 3 to 5 years?

Actually I'm with you guys. There's no way I'm making that trip to the hardware store to buy a quart.

But please, anybody willing to experiment, post your results.

well heck, I'm not sure without actually checking the composition of all parts that fuel would come into contact with starting from the fuel cap to the point of combustion. I've not dug too deep into this car yet mechanically but I'm sure my time will come soon.

Nothing to apologize for Richard. :)

And my comment of 3-4 MPG was to indicate an indeterminate improvement (after the initial cleaning). And only an improvement if a cleaning was really needed. I do remember one poster a year ( :?: ) or so ago that had the "belief", but soon faded away.

Yup its "old" snake oil with a few drops of truth. Just enough to ensure it won't ever go away ;)

Sincerely,

cold fusion welding

well - if you poke around a bit on that site, you'll also find a page about cold fusion welding - yes, even you can weld say - a steel rod to a brick. Think of it - you can weld anything to anything!l The possibilities are mind boggling. Oh, I forgot where I was - sorry for the thread drift.

ahh...the joys of cold fusion welding...welding my ice cream cone to a stapler has always been my dream. :wink:

Anyway - there are a few folk on another site I was reading (Mythbusters I think) who said that even after a few tanks with the acetone addditive, they would refill with just plain petrol for the following 3 tanks and the mpg went back down. They claim this proves that the improvement was more than a parts cleaning.

Could you imagine long term exposure in my wife's Prius - with that fuel bladder??? I think she would hurt me pretty severely.

Isn't the Insight gas tank plastic of some sort? Would be sort of exciting to have a catastrophic failure of the gas tank...

Maybe as exciting as sticking a fork in your eye...maybe even more! :cry:

I'm sure there are quite a few components in the fuel system that are plastic - and rubber too. Think of all those seals being eaten away....but on the good side, they would be super-clean right?

With 2-4oz per 10 gallons, the acetone would be extremely diluted. As long as no residual doesn't sit in the filler neck or anything like that, it shouldn't cause any harm.

AFAIK the filler neck is steel, and the lowest cost part that could be damaged if not.

Agreed that with such a dilute mixture damage will be slight and or long term. And the true cost / benefit will only be revealed in the long term. ;)

For me the risk / benefit ratio calculation is all that was needed to make up my mind. ;) Want 3-4 MPG higher :?: Unless your already hypermileing simply slow down 5 MPH. Does wonders for that old "white knuckled" feel behind the wheel too :!: :p

HTH! :)

I did try the acetone, 2onze per 10 gallons of gas, what i found is that i did make an improvement in the mpg aera, somewhere in the 5 mpg.
I also noticed an improvement in the responssiveness of the engine. I could feel the little extra whoof not by much but still noticable.

From what i have read, the acetone improves the vaporasition of gas thus improuving the overall conbustion process.

As of acetone and plastic, well they sell pure acetone in plastic containers
,cutex nail polish remover. I douth that such a small amount, 2 onze per 10 gallons, is going to have any affect.

My brother also tried it in is ford focus and also noticed an improvement.

Drop a line to Honda and see what they have to say. Odds are it'll be what you already suspect; i.e., don't!

We used to (and they probably still do) use it to clean military hardware and associated parts - works great in that regard but I for one would NOT recommend it for civilian applications, let alone something like one of our little Hondas.
