Summary

1992 Honda Prelude 2.3 L Auto transmission 4 piston front wheel drive. This car has 177,143 km (110,714 miles) on it. Tested from Apt 1, 2006 - Aug 15, 2006 for 2708 km (1,692.5 miles). 9.619 L/100 km (24.459 mpg) with 60 mL per 52 L of fuel. 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.

Manufacturer document said this city and highway mpg is 22 mpg and 29 mpg respectively. Since I drive this car only in Ottawa city, I consider myself a full time city driver. 3 months prior of test, I flush radiator, engine oil, break fluid, change to summer sport tyre 205/55R15.

I don't drive the car everyday, so 1 tank of 55 L fuel last for 1 month. I only recorded the original fuel consumption 3 months prior of adding acetone. Therefore, I only have 3 tanks of mpg statistics. I always gather the test for 1 full tank of about 52 L.

I only use regular 87 octane gas, although manufacturer manual recommend 89 octane.
