Miracle for fuel economy?

[crispixoo7]

i was at walmart this morning buying paint brushes for fiberglassing and walked right past the acetone....ALMOST stopped to buy some. i'll give you guys a couple more weeks first.

is it in the gold and blue metal containers? lol walked passed them and then remembered to get the 1QT can, a big "dropper" (one with the bulb and oz. readings to suck up the acetone) and a large funnel, so i can pour it directly into my tank (not getting it on the paint for sure)

will be updating within the week

I've been researching all over other forums to see if I could find anything negative about it. Mostly, people report what it has been reported here (better mileage, smoother engine...) but I did come across this thread where a "chemical engineer" bashed acetone. He doesn't provide any proof though, and his concerns have been thoroughly discussed elsewhere:

I'll keep searching to see what else is out there. One thing seems sure though: it has (or is still) been used in aircrafts which to mee is a good sign (as turbochargers, superchargers, NOS, water-injection...). I'll post what I find, if interesting.

 

[peepsalot]

There are a few threads on bobistheoilguy about this, but didn't find much good data or facts. Mostly people bitching that they already have threads about this and that it's been discussed over and over. I guess I never found that one original thread. (shrug)
Seemed like it would be a good place for info.

its all bulls***!!! isnt that right dana.........oh and ill be expecting that post in the f/s section tomorrow no later then 12am

 

[flipmode815]

work at a nail salon, eh?

no i work at a marble company

My first tank with Acetone gave me 365 miles compared to 330 normal. I am also running w/out this time to see if there is any difference.

Does anyone have an opinion on whether or not this would be safe with the new(ish) MSP flash? One post mentioned that it increased the risk of detonation but another suggested that this would work like increasing the octane level (which should decrease detonation risk, right?).

I dug through all the posts and couldn't find anyone who was obviously flashed and trying this out.

My car is flashed.

That's the single best thing I've read all day.

Usually get 440-475 miles per tank--call it 14.25-14.75 gallons per fillup or 30-33 mpg, depending on all the variables.

Put 4 ounces acetone in full tank this morning, (assume tank filler pipe holds about .6 gallon plus 14.5 gallon tank or 15.1 gallon approximate total fuel capacity). This is about .270 oz/gal or 2.7 oz/10 gal. Article references 1-3 oz/10 gal gas.

Depending on mileage at next fillup, I will put in 1 ounce less--3 oz/tank--and check next fillup mileage. If down, I'll go to 3.5 ounces; if up, I'll go to 2.5, etc., until I max out. This assumes I see an increase at 4 oz/tank.

 

[CHICO2003]

whoa! gino man... u must be an accountant or something! lol i just took a guess as to how much 3 ounces was.

 

[TurfBurn]

I have my 91 blazer running this.... does seem to idle and accelerate smoother... but likely a placebo affect... I swear it downshifted less on the drive in this morning (big hills) so it may be improving just in that department... but needless to say the drive I do every day I NEVER get above 15 mpg when going to and from... so I threw in 4.5 ounces of acetone (18 gallon tank) and will see how it treats me.... I'll do several tanks at the same level of acetone and see...

Some search results:

Here's a white paper from SAE (2005) mentioning acetone in fuel, although as a byproduct:
Combustion Processes Laboratories : Homogeneous Charge Compression Ignition (University of California, Berkeley). - The Effect of the Di-Tertiary Butyl Peroxide (DTBP) additive on HCCI Combustion of Fuel Blends of Ethanol and Diethyl Ether
http://repositories.cdlib.org/cgi/viewcontent.cgi?article=1009&context=cpl

Here's a quote:

"In the simulation, DTBP is seen to thermally decompose into two t-butoxy radicals, in the 600-650K temperature range.

(CH3)3COOC(CH3)3 → (CH3)3CO + (CH3)3CO

These radicals internally rearrange very quickly; primarily forming acetone (CH3COCH3) and a methyl radical (CH3).

(CH3)3CO → CH3COCH3 + CH3

The acetone is stable and lingers in the cycle until the main ignition promoting reactions commencing at temperatures of approximately 1100K."

==================

A very good thread on Acetone can be found here:

And this (posted in the thread above)

That's reassuring!

well i filled up my tank, bought acetone, a plastic dropper (labeled by oz.) and a plastic long ass funnel to get it in my tank....

sucked the acetone from the bottle, placed 3 oz. in the funnel, and poured it in...

went to clean the stuff up and found that the dropper had "melted" shut.... (hah)

how are you guys measuring the ounces?

 

[flat_black]

Bwaha! A glass graduated cylinder. Hehe.. A good dropper will hold up, made out of the proper plastics. The grades of plastic generally determine what they're made out of, and how they're made. The basic types are as follow, with the present saturation in acetone results. Keep in mind, if you saturated these items in gasoline, most, if not all, of them will react worse:

PETE    Polyethylene Terephthalate (PET)    LR
HDPE    High Density Polyethylene           HLR
V       Polyvinyl Chloride (PVC or Vinyl)   HR
LDPE    Low Density Polyethylene            NR
PP      Polypropylene                       HR
PS      Polystyrene                         NR

Results Legend:
NR - Non-Satisfactory Resistance - Dissolved or deformed to an unusable/unsatisfactory state.
LR - Limited Resistance - Softened noticably, but did not deform.
HLR - High Limited Resistance - Softened to a small amount, but did not deform.
HR - High Resistance - Did not noticably change state.

I tested out a container first. I used an old bottle of water based lube (I know what you're thinking, but it's to help wakeboarders get into the bindings). I measured out 2 oz. intervals on the side. It has a pop top and works well. I left it outside for a couple days and it hasn't melted yet.

i poured some acetone into a 1 gal gas container, then added .15 gal gas from the pump, swirled and poured it in with a full tank. ~1/10 16 oz bottle, so close to 2 oz in 14 gal

I bought a GLASS kitchen measuring cup, and a stainless steel funnel from Wal*Mart.

 

[CHICO2003]

just pour milk... soda... juice... whatever! into a measuring cup and fill it up to 3oz. notice how much it is and how long it takes... burn that into memory and viala! it doesn't have to be exact!

 

[FlyinMSP]

I used a smallish glass bottle (1/2 pint or so) and with a measuring beaker I had (from my photography days) I measured different amounts with water and put it in the bottle. With a felt pen I made different marks corresponding to my typical gas fills. Poured the water out, let it dry, and voil! Now I can carry my bottle with any preset amount of acetone.
