On-Road
Testing

Best Tech personnel tested the Synergyn® 2000 gasoline and diesel additives in six vehicles (cars, trucks and SUVs) in over-the-road tests. The engines ranged from 2.0 liters and 170 horsepower to over 15 liters and 600 horsepower. MPG improvements ranged from 10 and 24%. The results are presented graphically below:

The variation in mileage improvements range between 10% and 24% resulted from differences in the conditions of the test and the vehicle, including the age of the vehicle, temperature, humidity, and length of the test, road condition, congestion, and the programming of the engine computer.


Up to 25% XTrA MPG Increase in 11 Vehicles

Best Tech and its partners have performed on-road testing of the fuel and oil additives separately and together in twelve vehicles with both gasoline and diesel engines.

The variation in mileage improvements—between 14% and 25%—resulted from differences in the conditions of the test and the vehicle, including the age of the vehicle, temperature, humidity, and length of the test, road condition, congestion, and the programming of the engine computer.
