anyone try acetone in their 240?

[lrb_2000]

Well, I started putting about 2.5oz per 10 gallons of premium gas in my tank... and noticed about 4mpg more in town.. pretty crazy that it works.. car acually runs better, and accelerates smoother... just thought we could have a little discussion on it.. here's a few links to pages that have done testing.

remember, 10 Gallons = 1280 Ounces... So 2.5oz of acetone isn't going to acually be enough to harm your fuel lines, and such..

I may have to try that. My mom uses acetone with all painting supplys. Also the lab at my work uses it in some of their assay tests.

im definitley gettin some acetone this weekend. just last night i ran the tank down to E and put in 10 gallons of 93. i'm trying to figure my mpg. once i get back to E i'm going to put another 10 gallons in with 1 or 2 oz. of acetone and see the difference.

I used acetone to clean the inside of my door skins when I mounted my crossovers, does that count? Seriously though, I've never heard of using it in the gas tank, I may give it a shot.

[lrb_2000]

yeah really... I heard it on the radio the other day, and was kinda like, what the hell, that's like paint thinner or something lol.. but I started doing some research and people are getting some pretty good results.

[naed240sx]

any effect upon horsepower that you know of?

[lrb_2000]

dunno, guess you would have to put it on a dyno or something? I just noticed it running a lot smoother... kinda like when you've been running 87 then you put in 92. Just something to try I guess. but I did notice better gas milage, so that's a plus.

here's another article.

Pretty interesting stuff. I'll plan on trying this out too. Everyone here on Nico should too to see if everyone gets similar results.

[sensibleS13driver]

My engine is so old I worry about some seals though... any knowledge about how it would affect them? I think I'll play it safe and use less rather than more.

[dmansofly]

hmm sounds iffy, cause acetone ate up the internals of my $200 paint gun over night (all the plastic and seals). I can't imagine putting that in my gas tank.

[lrb_2000]

did you read the articles? they have all the information you need.. you're using such a small amount, 2-3oz per 1280oz of gasoline, I doubt it can really harm anything... I just can't believe how much better gas milage i'm getting.

Hey guys one the subject of fuel additives, has anyone tried Toluene, back in the old days they used to use it alot for high compression engines as it has a high natural octane (i think it was in the 100-110 range) I remember see a site a while back that explained the process of mixing it but it was similar to the processed explained here with acetone, http://en.wikipedia.org/wiki/Toluene , theres it's chemical properties and some other info. I'll see if I can't find that site out there.

EDIT: I found some more info on this subject Toluene has a Octane of 127, Toluene appears naturally in gas as a byproduct of refining, and from what I gather it replaces missing hydrocarbons or something like that which safely leans out the A/F. Also Xylene (same family as Toluene) has an octane of 165. Ooo and both of these chemicals ARE EXTREMELY DANGEROUS, so make sure you read up on safe handling of this stuff, and last thing TNT (dynamite) stands for TriNitro"Toluene"....

This is awesome. I'm going to do it ASAP in the morning. I'll report my results if I see any!

[hek1620]

so, i got 217 miles on 10 gallons. 21.7mpg. is this good. i'm thinking this is a little low for a four banger but i don't know. what do yall think?

[hek1620]

now i'm gonna try 10 gallons with a little acetone.

[ricebike]

so, i got 217 miles on 10 gallons. 21.7mpg. is this good. i'm thinking this is a little low for a four banger but i don't know. what do yall think?

hmm, i'm averaging 25 mpg on my 1989 sohc engine <mainly higway driving on 130/ 295> w/out using any of this stuff... i just keep my oil changes/maintenance items in check & have 87 octane. 230,000 miles on it & will probably seafoam the car next spring to keep it that way :P

it's a good read, but i gotta go some mo' research to justify putting this or mothballs in the gas tank. <edit: mothballs don't do shizzle; i just recalled an episode of mythbusters>

This is a great article on toulene over at 240sxforums.I don't think toulene is as cheap as acetone but I would dare to say still very affordable.http://www.240sxforums.com/for...63400

[wilfonzo]

yeah, what about mixingtoulene+acetone+gas=fun?/not fun(brokenmotor)?

[manasol]

The fear is what chemical reaction would there be with acetone and toulene. I wouldn't try it as I really am not educated on the subject more then what I read on that article.

[wilfonzo]

same here, hopefully a chemist stumbles upon this post

I get 21-22 mpg city, and 28 mpg highway on a DOHC, so 25 mixed sounds about right, and the other gentleman's 21.7 is good if that's all city.

[ricebike]

side notes:

recalling mythbuster's list of crap they added to the gas tank to try & kill the engine....

bottle o bleach is a great oxidizer that formed rust all over the tank, clogging the pickup screen/sock

i think sugar in the tank had no affect...

[hek1620]

those miles are highway and city. with and w/out a/c. my brakes are grabbing a little bit and i have a system in the back. could this be the reason for poor gas mileage?

[mirra32]

i'm a little interested in this....i used sea foam in my old e motor and it made a big difference.....post your results using that ace...stuff

[Nismo_Freak]

It's similar to using an alcohol additive into the fuel supply, in that it it strips built-up carbon deposits off of components increasing flow and moderating heat build-up.

However unlike alcohol it doesn't dry out seals as bad, isn't hydrophilic, and is available everywhere (even gas stations!).

It doesn't introduce any funny chemicals to the system so your by-products are the same and vary in quantity by availability (atomization) and combustion efficiency.

By reducing surface tension in warmer climates I would be willing to bet you would lose alot of fuel into the carbon canister. So the colder climates might see better gains due to the reduction of this loss.

One thing I think is a bit odd is the relative small amount of additive per L. It seems to me that in order to increase the atomization of such a large quantity of hydrocarbon passed through the system and into the injector you would need to include quite a bit more additive. All speculative to me but alot of pleb-tests have been done on it and people are netting gains. How much of that is due to placebo or actual acetone who knows.

Also for those using ethanol mixed fuels, I don't think you will see much of a gain from using it in such low quanities.

1. Don't associate chemicals by name. Just because toluene is a base in TNT does not make it unstable. It's the nitrogen oxide groupings that give the substance it's thermodynamic nature. It's full name is 2,4,6-trinitromethylbenzene, and it isn't very volitile at all. You need to use a primer to detonate to support the organic decomposition of the subtance. You are thinking of nitroglycerin which is the red headed step child of the whole TNT discovery.

2. R/M ratings for Xylene are 119 octane, and 116 octane for Toluene. This is the actual octane of the fuel in comparison to our fuels.

[FattyMcBaggins]

The reason Acetone is better than alcohol is because alcohol mixes with gasoline and end up forming some water particles, so it actually hurts your performance and will damage seals and such.

[ricebike]

"whatcha talkin' about, Willis?" (gary coleman)

soo those gasline antifreeze alcohol based products don't work to absorb the water in the fuel tank? esp when people don't keep @ least 1/2 tank of fuel so that condensation won't form & have water in the gas?

i also recall up to 10% water content in the gas is acceptable; heck water is a decent carbon cleaner

[Spongebob]

Chemtools b-12 fuel additive is mostle toulene and acetone so i don't think its going to blow up the car. Gasoline can blow up too.

Sorry for the misunderstanding, I was refering more towards the dangers of fumes/ingestion then towards combustion, if I recall correctly because of the makeup of Toluene your body cannot naturally dispose of it via water (piss it out) and the fumes are supposedly quite toxic. But not only the fumes, the exhaust is quite potent with hydrocarbons and the such after combustion (way more then usual, so you Cali guys are outta luck) so please do use caution when using it *disclaimer fine print*

Ricebike, I work at a gas station, and one of the things you do at a gas station (obviously) is to monitor the gas readings, which come by in big long print outs of all the different stats (volume, temp, etc.) one of the things we have to monitor is the inches of water that reside in the gas tanks (the big underground ones, we have four 8,000 gallon tanks) I did the math one time during the winter (when we're incredibly slow on 3rd shift) and lets all hope that the water/gas ratio can sustain more water then that as I remember having something like a 17% water content (not including errors for sludge, etc. that build up at the bottom of the tanks.

Moral of the story... don't get Citgo gas.
