I started testing Acetone in one of two vehicles on Saturday March,
26th.
Bought a quart of 100% Acetone at Lowes home improvement. Stopped at
Walmarts and bought a long neck funnel and a small glass measuring
cup that was made to measure small amounts........this cup holds a
max. of 4 ounces. Total cost for Acetone,long neck funnel and
measuring glass under 10 dollars.

Test Vehicle 1: 2000 Ford Ranger. 4x4 drive factory extreme off road
package. 4.0 liter V-6 5 speed automatic transmition. 48,557 miles

Test Vehicle 2: 1995 Pontiac Bonneville. 3.8 liter V-6. 4 speed auto
transmition. 129,000 and change.

Both vehicles in very good mechanical condition. Both vehicles had
STP injector cleaner run through the week before testing to begin
with a known base. Tires have been checked and are at proper
inflation.

Test on Vehicle 1
Added acetone at a ratio of 2onces per 10 gallon. 19.5 gallon tank.
Actual measuremnt: added 4 ounces of Acetone to tank and then added
10.7 gallons to top off tank.

Initial obsevations. After driving in town for approximately 2 to 3
miles,noticed that the idle seemed to be smoothining out at stop
lights. This 4.0 engine is a little radical being an Extreme off road
edition. This was noticed both by myself and my wife. While wifey was
in doing the food shopping I checked the oil and tranny fluids just
to make sure everything was at proper levels. One thing that was
noticed was that while in park and idleing to check tranny fluids I
had walked to the back of the truck for some reason and I noticed
that there wasn't the usual pertol exhaust smell from the exhaust. I
mean nothing. I guess people thought I was taking the gas pipe or
something. I actually got down and stuck my nose in the exhaust and
still nothing. I thought maybe my sniffer was on the fritz so when
Linda came out I had her take a sniff.....still nothing even after
sitting shut off for twenty minutes and then restart. From this I am
of the opinion that there must be something to the theory that the
acetone does make the fuel spray in the engine much more efficent by
changing the surface tension of the fuel hence all or nearly all the
available fuel being delivered to the cylinders is being burnt.
Second Observation, while it is still way too early in the testing to
make any claims one way or the other concerning increased milage, I
most definately noted an increase in horse power. The drive from
Hanover. PA to my home in rural Maryland is just over 20 miles mostly
rural driving with one small town to go through. What I noticed is
that it was very apparent that I was driving as though I had a raw
egg between my foot and the gas pedal. I didn't have to depress the
pedal nearly as much as normally. And also by the time we got home
the tranny was shifting a lot sooner and more positively. I don't
know if by then the computers had made adjustments or what was up.
But the vehicle is definately running better and with what seems like
less fuel being needed to drive at a given speed. Now does this equal
to better milage, the jury is still out. Tomorrow we are taking it
for a 150 mile trip to see her folks. This vehicle has never been a
real gas saver, average real world driving rural and town about 18
miles a gallon. So tomorrow will tell the story I guess. I'll get
back when I know something more.

Test Vehicle 2: Tomorrow I will fuel it with acetone and gasoline and
she will drive it to work next week. The milage on this vehicle with
her driving pattern is as predictable as day and night. On her work
commutes it's right at 25 mpg this week.. next week and every week.
So it will be interesting to see what next Friday brings with this
vehicle. More to follow on this next Friday or Saturday.
