Save Fuel With PRI- Guaranteed!

It's true! With PRI-D for diesel or PRI-G for gasoline, you will achieve the same fuel savings experienced by our industrial clients! Documented, long-term fleet field studies of PRI application on hundreds of vehicles confirm an average fuel economy improvement of 8.8 percent, with individual savings ranging from 5-to-15 percent and more!  Even on the cleanest, laboratory engine, burning the USA's cleanest California Air Resources Board mandated fuel, results of the CARB-EPA 13 mode emissions test confirm a fuel economy improvement of 4.7%.

How? First, the unique thermal stability capabilities of PRI produce more energy value per unit of fuel. Secondly, PRI keeps engines and fuel systems cleaner - operating closer to the original design specification. Fuel injectors provide optimum spray patterns. Fuel delivery systems remain deposit-free. Your engine runs better than ever.

RUN MORE EFFICIENTLY ON ETHANOL BLENDED GASOLINE WITH PRI!

E-10 and other ethanol blended gasoline formulations tend to have less energy value. While PRI does not elevate the overall BTU value of these fuels, the thermal stability chemistry of PRI-G does help squeeze just a little more of the existing BTUs from each unit of fuel by permitting cleaner combustion.

Additionally, PRI-G will keep your fuel system deposit free, enabling it to operate at maximum efficiency.

KEEP THAT OLD VEHICLE RUNNING GREAT!

Using PRI with every tank of gas or diesel fuel ensures that your older car and truck will continue to run great year after year.

244,000 Miles And Still Running Strong!

At right is one of our PRI work trucks - a 1990 Chevy 1/2 ton Silverado. Inaugurated into PRI service in February 1991, this truck now has 244,000 miles and is still running strong thanks to continuous PRI-G treatment since day one! On 87 octane gas, this truck gets 17 mpg in the city, and 19-21mpg on the highway - better than the original rated EPA fuel economy ratings for this vehicle.

That's right. If you are not completely satisfied with the performance of PRI-G for gasoline or PRI-D for diesel, we will cheerfully refund your purchase - no questions asked (see bottle label for details).
