Years ago (prior to using acetone), I performed a test of 100% acetone on plastic fuel line, fuel rail gaskets and internal fuel injector gaskets. I found that acetone will swell gaskets, but *does not* degrade them.

4 oz per 10 gallons is the upper limit on acetone use in gasoline (1:320). Using more than that will degrade fuel economy. I did further testing using 1:160. This double-strength ratio did swell gaskets very slightly, I'd estimate less than 5%.

I've used 3-4 oz per 10 gallons now for three years with only positive effects.

In the final analysis, I would say it's not only safe to run acetone up to 4 oz per gallon, but if you have a slightly leaky fuel delivery system due to old gaskets, that it may very well swell them and seal the leaks.

AFA screens are concerned, I know there is one company that makes intake manifold screens that supposedly increase torque. However, if you are planning on putting a screen setup immediately downstream of your carburetor, you might want to consult this first

AND ONE LAST TIME: 7oz of xylene or toluene will act as an octane booster, giving you the benefits of mothballs w/o the danger.

AFA mothballs (naphthalene) in your tank are concerned...

" Naphthalene can greatly enhance the output and efficiency of internal combustion engines because it is an octane enhancer.

However, in a solid form i.e. flakes, powder, etc., the following can result with continued use: Due to the ratio of carbon to hydrogen in the molecules, an engine will eventually get loaded with carbon deposits, but only if the fuel filter doesn't clog, or if the injector pump doesn't fail, or if the injectors don't get plugged up first. Fuel system failure is common with continued use of Naphthalene."

So if you'd rather risk using them instead of xylene or toluene - If your engine starts knocking and pinging because you've carboned it up... Don't say nobody told you so.

Hello. Acetone will affect rubber gaskets and seals... if you use too much. I only use 1oz per 10 gallons. Just a drop in the bucket. Remember, the acetone is not used as a fuel but as a surface tension release to the gasoline. Everything I've read about mothballs in all the searches online that I've performed do state that they increase MPG. I'm happy with 4 balls to a gallon. That's 1 ball per quart, which doesn't seem excessive. I used some of my mothball gasoline with the 4 balls to 1 gallon mixture in my lawn mower and dang! I did the entire lawn and then some. Usually my mower will only do 3/4 of my yard before going dry. The important thing here is experimentation and results. Just like you, I've increased mileage and performance dramatically! My old Edsel 6 cylinder purrs like a kitten and has lots of pep with my additives. I've yet to use toulene but I believe the results would be the same. Reduced surface tension makes for easier vaporization in the carb/intake manifold. My next big experiment is placing a piece of wire (not plastic) window screen between the carb and intake manifold. From what I've read, the gasoline, in passing through the wire screen mesh, will break up into smaller droplets than what I'm getting now without the screen. My only concern is that the screen may reduce airflow a bit. Once installed, I'll do a 1 gallon real-time road test and check for any increased/decreased mileage. Finally, I had said that the tail gate in the up position on a pickup truck decreases air flow and increases drag. The tail gate should be down (or install a net, as you've done).

Hola Dave et al!

NEVER USE ACETONE in an will mess up the seals, gaskets, has been outlawed in the Phillipines...refer to the recent news
article on KeelyNet about it DESTROYING engines.

Toluene, yes...

Mothballs, YES if you don't use too many...I have been using 1:4 in my
1996 Ranger for nearly 4 months now....was getting from 18-22mpg, with
mothballs, I get around 30-35mpg!!!  And it runs better than ever, has
more power and I can climb the mountains on my weekly trips to nearby
towns.  Been to Goodyear twice and they said the motor is in very good
condition for a 1996.

The problem is some people use WAY TOO MANY mothballs....the original
recommendation was 1 ball for 4 gallons...thats what I've been using.

They will carbonize the engine if you use too many and require repairs.

I think you have that wrong about the tailgate DOWN degrading
mileage..its running your pickup with the tailgate UP that produces the
resistance to lower your mpg...

Thats why they have the NET gate that lets air pass through it, but
tonneau cover is even better.  Living in central Mexico, I just load it
up with Mexicans wanting a lift and let them be the airfoil....<lol>....

Nos vemos!

Hey Mark,

Dude... DUDE... Skip the mothballs. Naphtha will eventually screw up your engine.

Try adding 1-2 more oz of acetone per 10 gallons. The sweet spot seems to be 3 oz, some people do better w/a little more or less.

Also try 7-10 ounces of toluene or xylene and advancing the timing (toluene is used commercially as an octane booster, xylene is very similar, and both are 50-75% cheaper if you add them in yourself as opposed to paying for the 'pre-blended' mix at the pump).

Try the Mobil 15k synthetic oil. You change it less and it costs the same as running cheapo oil.
Add 4 oz of Torco MZP engine assembly lube to your gearbox.

Also, try a chin spoiler.  This will block air from your undercarriage.

Do all that and you'll probably have a 33MPG 59 Edsel.


PS running your truck with the tailgate down degrades MPGs. Running a tonneau cover (even a 1/2 cover from the cab back) increases MPGs.
