Acetone...is there a conspiracy?
 

Hope this doesn't SCARE anyone on this forum.....


Article:Truth About Acetone and Ethanol - PESWiki

Test car: 1985 Ford T-Bird 5.0L V8 EPA rating 15 MPG city and 22 MPG highway.

Emissions test using pure 87 octane gas resulted in Hydrocarbons of 190ppm at idle. Fail is 220. O2 was 1.5%. This was suggestive of a small exhaust leak, which the O2 sensor read and richened fuel:air mixture a little too much.

Emissions test using 1 oz. Acetone to 1 gal. gasoline resulted in Hydrocarbons dropping to 111ppm at idle. O2 at 1.5%.

Highway test with this mixture resulted in 23.5 MPG. According to data on the internet, at this very high amount of acetone, MPG should have dropped far below factory. That it actually got slightly better than factory gave away the secret. The slight exhaust leak had richened the mixture of fuel:air and caused a SLIGHT utilization of the acetone.

I saw that the O2 sensor played a part in my results. What I did next was create an INTENTIONAL slight exhaust leak, in front of the sensor to increase O2 in exhaust, to cause computer to richen even more. [leak causes sucking in of fresh air].

Emissions test resulted in increase of Hydrocarbons from the previous 111ppm to 144ppm at idle. O2 went from 1.5% up to 5.2%

Noticeable increase in HP of at least 25%.

Multiple hwy. tests revealed 45mpg.

This is slightly more than a 100% increase over factory.

Tested at .7 oz. per gal. went down to 41 MPG.

Tested at 2 oz. per gal. went down to 30 MPG.

By process of elimination, the best acetone mix for my current fuel:air richness is around 1 oz. per gal.


The secret, known to racing technology, banned and forgotten a half a century ago, is that such fuels as acetone REQUIRE richening of the fuel:air mixture to make use of them. It is said that in those early days of racing, some used as much as 10% acetone additive. I am using less than 1%. Specifically 1:128.

With my emissions at slightly cleaner than gasoline, but my MPG at double what it was, a REAL REDUCTION IN EMISSIONS has been achieved. Fully 50% reduction.

The recent G8 summit set the goal of reducing emissions by 50% by the year 2050. President Bush has signed in to law the requirement for vehicles to get 37mpg by 2020.

We have the technology RIGHT NOW to achieve this IMMEDIATELY.

Reprogramming auto computers is already possible and programs and devices are on the market to do so.

A simple solution for the do-it-yourself mechanic, until the use of the technology becomes affordable and the additives are at the pump, is to TRICK your O2 sensors into making the computer richen. This can be done by either creating an exhaust leak in front of the sensor or by removing the sensor from the exhaust and letting it read pure atmosphere, which is 20.9% O2. The latter will richen mixture to MAXIMUM allowing the most acetone possible and the most HP AND MPG. I have not tried the latter and do not know how well it would work or to what level of increase in HP and MPG might be possible. Try this at YOUR OWN RISK.

* read the Addendum at the bottom of the page....

Interesting indeed. How truthful is it i wonder?

:rolleyes::rolleyes::rolleyes::rolleyes::rolleyes:

...FWIW acetone dissolves fuel-system gaskets and eats at aluminum.

From the site.

Okay, I've read as many of these "Acetone" articles as I can find. It always seems to be half and half... Some people say the stuff worked in their car, and others say it lessened their FE.

My question is, has anyone here tried the stuff?? So it eats at aluminum, has this been proven? It eats at gasonline gaskets in the fuel system, has this been proven? Sorry, I just want to see some data from guys who seem to have a better handle on the differernt variables that come into play... And you ecomodder guys are the ones to test this....

You made basically the same thread already.

Comparing a DIY "highway test" to the EPA's highway test is invalid.
It's full of red herrings and as admitted in the addendum, errors.

Furthermore, you support every out there BS snake oil way of increasing your mileage.

Troll anyone?

It's the same stuff over and over.

...well, I'm not an anyone (maybe a nobody?) but, yes, *I* tried it and those were the results that *I* got during my experiment.

...you're more than welcome to repeat the experiment(s) for yourself, using your car engine as a "guinea pig," but remember: you were forewarned of the BAD things that can happen...as they say: YMMV and so will your results.

darn.

I was going to inquire about adding it to maines slop of crap called 87 octane made of fermented wood. :rolleyes:

I seem to be moving the "diesel" back out of the tank now anyhow.
