Very interesting read.
I've started some experiments myself.
Test subjects:
1982 Dodge W150 pickup that barely runs, is unregistered, used for plowing
my driveway and moving dirt, logs, whatever around my property
1998 Ford Explorer
Generac EXL 7000 gasolene powered generator
I added 3 oz to a tank of gas in the Ford and Dodge.
Because I also got an oil change, air filter and transmission fluid change
on the Ford, my results cannot be attributed with certainty, but I will
state that the vehicle seems to have more thottle response than before.
The Dodge has a clogged up carb, hasn't run on all 8 cylinders in about a
decade and barely runs well enough to plow snow from my private road each
winter. It also had a bad after-run problem, where the engine would keep
turning over in a 'klunk-klunk-klunk' fashion.
Adding acetone to the fuel and operating the vehicle for ten minutes, I
noted that for the first time in about 10 years, it will idle smoothly, as
if running on all cylinders. When I shut it off, the engine shut off
cleanly, without after run.
I added about 1-3/4 oz to the generator, which has a 7 gallon tank. It's
impossible to tell if there is any operational improvement without a heavy
load. I ran it for 30 minutes while I used to power for running my electric
chain saw to cut up some logs. Normally, when I shut down this generator, it
will backfire or post-ignite in the muffler, after the engine comes to a
stop. With the acetone, the generator shut down without the backfire in the
muffler this time.
I will be driving to Florida in a few days and this will be a great
opportunity to test the mileage results on a long trip with a lot of sample
data.
As an aside, I am interested in any ideas for improving the aerodynamics of
the '98 Explorer, so as to have less wind resistance at highway speeds.
Reducing wind drag can make the most difference, as a significant portion of
engine output is used counteracting drag. I have the stock Explorer, and am
wondering if there are any simple modifications that can be made to reduce
turbulence and drag. Has anyone got any wind tunnel test data for the
Explorer?
