Note About Acetone Results
Take this information with a grain of salt. I believe that some of the claims here are exaggerated because people not only added acetone to their tanks, but also altered their driving habits - likely without realizing they were doing so. Overall, in my personal experiments, I saw a gain of about 10% better mpg while not altering my driving habits.

Personal Experiences of People Adding Acetone To Their Cars
"Acura
1992 Acura Integra
Fuel Drops Mileage by 1.1% - Four runs of ~100 miles, two without acetone, two with, did not yield increased mileage as expected, but a slight decrease. Ratio may be too rich.
BMW
1994 BMW 325i
After 1 month of use OBC indicates an increase in inner city gas mileage from 19mpg to 23.5mpg. Car runs smoother, most noteably the throttle response.

1994 Ford Escort
Mileage and performance improvements
1997 Ford Escort
After running 7 tanks using varying amounts of acetone, and different grades of gas, I still am not seeing any improvement over 1 or 2 MPG. Still continuing to use it though and trying to come up with some solid results. In the process of increasing my acetone by 1 oz each new tank. I am testing around 5oz/tank
1998 Ford Escort
2,000 miles with acetone so far. Went from an average of 270 (was impossible to go over 300) miles out of 10.5 gallon tank to an average of 330, and a record of 363 by using 3 oz of acetone. Same if not worse driving habbits (gotta love the improved acceleration). I will never drive without acetone again. -- Alex K.
1999 Ford Expedition
27 percent increase at 50mph and a 33% increase at 70 mph. FarleyS.
1996 Ford Explorer
16.7 to 20 mpg with 3 oz / 10 gallon mix.
1995 Ford F150
I have a Ford F150 with a 5.8 liter. V8 Truck has approximately 157,000 miles on the odometer. I have run the acetone test with the following results while using 2 oz. per ten gallons normally I get about 220 miles per 17 gal. tank. With the addition of acetone the mileage has gone up to 248 per 17 ga. tank. The acceleration is improved and morning start up is almost instant.
2004 Ford F150
16-17 mpg hwy before; 22-24 mpg hwy after
2002 Ford F-250
Powerstroke Tests; still testing, but so far a loss in mileage for Diesel; black smoke has gone away
Ford Ranger
Initial findings from adding 2 oz / 10 gallon ratio: increased power, better idle, better shifting. 25.5% increase in mileage in Ford Ranger 4x4 Extreme with acetone added in ratio of 2 onces per 10 gallons.
Ford Ranger 4x4 Extreme
Increase by 32% at 2.5 oz/10gal.
1988 Ford T-bird
Mileage increases 18%
2000 Ford Taurus
No mileage increase noted yet. Only one tank and I poured 6oz for the 18 gallon tank. However, car idles MUCH smoother.
2002 Ford Windstar - Mileage decreased by 1-2 MPG using 2.0oz acetone per 10 gal fuel. I believed it is the additives in the Cali. gas that prevents benificial results. I have a buddy with the same vehicle in South Carolina who got a significant increase in MPG.
Note From The Professor: It is likely this individual was using gasoline that had higher concentrations of alcohol in it. Alcohol counteracts the effectiveness of Acetone.
2003 Ford Escape
When experimenting with different mixtures, use that mixture for TWO tanks of gas. I've learned single-tank acetone experimentation is almost COMPLETELY unreliable. That said, my 2003 ford escape gets 18.5 mpg on plain gasoline. I've had the following success with multi-tank mixtures of the following:
1oz per 16 gal, nothing.
2oz per 16 gal, 1 - 2 mpg increase. Engine idle down by 50-100rpm.
3oz per 16 gal, 2 - 4 mpg increase. Engine noise reduced, idle speed not recorded.
4oz per 16 gal, 4 - 6 mpg increase. Engine accelerates smoother.
5oz per 16 gal, 3 - 6 mpg increase, this appears to have about the same effect as 4oz.
6oz per 16 gal, 3 - 5 mpg increase. mpg is going down slightly. anything above this decreases mpg.

2000 Honda Odyssey
Improved mileage and performance.
2004 Honda Pilot
20 to 25 mpg with mixture of 3 oz per 10 gallons of fuel
1993 Honda Prelude
NO CHANGE!
1992 Honda Prelude
No significant increase in housepower. Original is 13 L/100 km (17.759 mpg). Pure city drive in Ottawa, with average speed < 65 km/h (40 mph). By keeping 60 mL of acetone, fuel consumption is keep on dropping for every refill. I suspect it is cleaning up the carbon deposit, or something, and making more efficient fuel consumption. By theory, 60 mL of acetone should show constant mpg, if driving habit does not change. However, I still don't archive it yet, so I will expect 60 mL will continue improve the mpg in next few months. I should perform another test without acetone, if it has clean up my engine.
2007 Honda Pilot
Vehicle was running at 20 L / 100 km. Since then started with 2 oz for the 72 liter tank. Mileage was improved and definitely more pep. Decreased the amount of acetone to 1/2 oz for every half tank and the fuel efficiency, mainly city driving improved at 17L/100km. Tested primary highway driving with the aceton and discovered 14L/100km. Really great mprovement.
