Acetone as a Fuel Additive
"The use of acetone greatly improves mileage AND engine life."

What do you think? If all of that was true, is acetone expensive enough to compensate the 35% gain in mileage?
Cheers,
Alex

acetone is already inyour fuel , adding 35% will prolly melt the rubber lines etc , its much better to just add toluene 
no pinging , det , and its cheaper than fuel

On the second link he doesn't recommend 35% - more like 0.35%!
1 ounce (presumably 1 fluid ounce) per 10 US gallons.

Is toluene dry cleaning fluid?
BTW did anyone notice that the propellant in "squirty cream" is nitrous oxide?
mmmmmm, i need a split system - nitrous into the engine, cream onto my stawberries.

Forget acetone, use celly thinners, they are a mixture of Toluene, Xylene and Methanol. (nearly all Toluene)
These are all very good anti-detonants and it's around £5 a gallon. (so similar price to petrol then!!)

or ahem , use neat toluene , if you can get it in big enough quantities

out of interest, has anybody braver than me run a car engine on neat thinners/toluene?
I have run my lawnmower on it but not the car!

no bothers at all?
I guess not but what fuel lines are resistant to the toluene?..............................ahhh, think I have just realised, overbraided ptfe lines
will be, using them anyway on the 7!

just had a message from a knowledgeable chap that used to post on here and he has confirmed the above.
Also pointed out that gunwash thinners are around 115 octane and are £12.50 for 25 litres from his supplier - 50p per litre for 115
octane...................hmmmm, tricky descision!

I had been looking at gunwash thinners for the same purpose its £11.95 plus vat for 25 litres from Autopaint. I understand it is mainly filtered or
distilled from used thinners from my web searches but am unable to find the general make up of it, is it mainly Toluene? or more methanol and Xylene
if so what is the maximum percentage that could be used ?.Is the calorific value similiar to petrol or is it like alcohol where more is required
therfore bigger jets and higher consumption? I have also used thinners in the lawnmower when i have run out of petrol partway through cutting the lawn
and find it actually seems to run smoother.
If the mixture is similiar the only drawback I can see is the fact that it may dissolve seals etc and may need some uppercylinder lube added or in my
case lead replacement additive.

thinners is more acetone and xylene , with a bit of toluene .
i dont think its as high as octane as toluene , cos ive worked it out myself , otherwise F1 teams would have used thinners during the turbo era .
toluene is 114 IIRC

While Googling on this subject, I found out that Acetone was a major component (10%) in Maserati's F1 fuel during the 1950s...
...so it's nothing new after all.

The thinners I have (tetrosyl normally) gives it's ingredients on the label as Toluene as main one and Xylene (small %) and methanol (less than
5%)
Will check the exact % at home, but certainly no acetone in it at all!

Alez, back to the original fellow -- the tiny bit of Acetone this guy says to add will do absolutely nothing chemically, the placebo effect on your
right foot could easily save you 25-30% with careful driving though.
One of the best, and cheapest, economy devices to invest in is a vacuum guage, more vacuum=better fuel economy.
Cheers, Ted

Even cheaper than a vacuum gauge imagine you have an egg betwwen your foot and the accelarator pedal

Against my usual caution, and the levels of acetone required being quite low and not too risky, I have tried some in my 15 month old laguna 1.9
dci.
I have done this the last two days. I do 50 miles journey each way to work. Pretty much average 50 mph, and there are no real hold ups. Its
essentially constant speed driving between 80 and 40 mph.
The stuff on the web reccommends 0.5 - 2.0 ounces per 10 us gallons.
So, day one - use the minimum 0.5 ounce mix.
Bum all difference.
Next day - use approx 1.2 ounces.
bum all difference.
I suspect that the only reason people see an effect is if their car is a big shagged. Perhaps the slight solvent effect cleans the injectors. As my
car is young and only has 26k on it, i suspect it doesnt need a clean out. Reading stuff from some people, they say their car had better acelleration
too - this would be the case if the injectors had been cleaned from a blocked state.
So, comparing the mileage I have, from a reference journey I have done for many months, I can confidently say that adding Acetone to diesel is
complete tosh - unless you are driving an old wreck, where the fuel improvement may just be what you should have got if your car wasnt fooked in the
first place.
Just my opinion.
