I found douses of website claiming that adding Acetone to your gas
will improve your millage.   The only way to know for sure is to try
it, but I want to make sure it is safe for my 2002 Saturn sl1.   I
wonder if it was premixed with my gas before poring in the gas tank,
would it not eat through any rubber seals in the system?   Any one
have any experience trying Acetone for the vehicle?   Please don't
respond just for the safe of shooting down someone's idea, or your own
speculation.  Thanks.

Acetone eats plastics.  If you take a long look at a parts list for
your fuel system, try an find all the different plastics in use
including some fuel lines.  Nylon does't seem to be easily affected
but if I were you I'd get a small container of the stuff and test it
on some differnt plastics.  Then smear it out on the outside of all
synthetics I could find (be prepared to destroy them).   Be amazed at
what melts.

Acetone is cheap.  If it actually improved mileage, the oil
companies would be putting it in there already.

Properly inflated tires and clean filters will improve your
mileage.  Acetone will remove your fingernail polish.  If, you
know, that is an issue.

I disagree, oil companies want to sell more.  Already 1 surfactant
can incr torque ( even 20%, after 1yr use ) & decr noise ( 40% on
diesel ), surely incr mpg, oil co.s are unlikely to want to add this
into their petrol / diesel.

Most cars have design flaws, corecting them is 1 way to incr mpg.

Oil companies might object to adding acetone but I think this claim is
not credible for the reasons stated above. I believe they know it is a
worthless addition. Car manufacturers under pressure to increase fuel
economy (marketing and regulatory) have tremendous incentive to
increase fuel economy. If acetone did anything, anything at all
(increase fuel economy by 0.1%), the car companies would demand it be
added to fuel. If  the oil companies refused, then the car companies
would add acetone metering units and sell the stuff themselves. I have
a couple of friends who have bought into this myth big time. In every
case where I asked for records to prove the claim, it was obvious that
they had nothing that approached credible evidence.  Poor data
gathering does no equal an actual improvement. People have been
believing in the miracle fuel economy "improver" for as long as people
have been building cars. The EPA has tested acetone and many other
miracle fuel economy improvers and found almost all to be totally
bogus.

Most car definitely include design flaws, but the cheap crap sold as
fixes is usually bogus. Acetone, magnets, swirl inducers, atomizers,
etc., etc., etc. are just a few of the more common scams.

Only if they own the oil companies.

They don't produce petrolem products.

This surfactant I buy & use can work.  I don't publicise this fact
( or the common design flaws I found & corrected ) because 5%
of the drivers & bikers here in Msia are bastards ( esp 1 neigh
bour with same 2 cars as mine ), I don't want them to benefit from
my discoveries / effort, however much I like to decr CO2.

I had 8 ( neodymium, very strong ) magnets fitted on my fuel line
, & test driven for 5 minutes. No difference was felt.

Swirler ( if well made ) in carburetor can cause finer petrol mist
& incr torque ( as on BBC 's Tomorrow's World in 1984 ): I felt a
small 1-2% extra torque in my test drive with *"Cyclone" ( from
Korea, its 8 fins were too few to create more swirl ). My govnmnt
studied * & found a tiny drop in CO / NO discharge.

You are so correct, but how far can one go with this?  Should we check
our tire pressure every mile and change the filters daily?  

This is about the same as the advice to save home heating fuel.

1. Turn down the thermostat.
(I do this every time someone recommends it.  Now every pipe in my
house is frozen and I am in the hospital).

2. Insulate.
(I do this everytime someone recommends it.  Now I cant get in the
door because the insulation has filled the entire house.).

Yes, there are good tips, but they are very basic information that all
of us should know by now, and yet the media keeps rubbing it in, while
ignoring the larger picture.  I'll inflate tires, change filters, turn
down the thermostat, shut off lights, and insulate my home, but when
is industry going to do their part?  When are they going to make cars
that get good mileage?  Cars that run on alternate fuels, home heating
that uses less energy, etc.....?

Check tire pressure monthly. Replace filters at the manufacturer's
recommended interval (no sooner). As long as you are close to the
vehicle manufacturer's recommended tire pressure, the rolling
resistance of radial tires varies very little. Air filter
contamination has a very minor effect on the fuel economy of modern
fuel injected engines (unless you just completely plug the filter up).

If you really want to get the best fuel economy, drive slower, drive
like you don't have brakes, empty out any extra weight, if the check
engine light is on get the car fixed, maintain the car per the
manufacturer's recommendations, don't use E10 fuel, buy low rolling
resistance tires, make sure the fluids are the proper viscosity, get a
car with a manual transmission and shift into higher gears as soon as
possible, get the smallest lightest car you can stand, etc., etc.,
etc.
