Industrial grade PRI Fuel Treatments have been tested and proven at the world's most highly regarded independent laboratories. PRI Fuel Treatments are laboratory and real world proven to provide maximum protection against damaging, power-robbing deposits. PRI stabilizes fuel for years of storage and even restores degraded fuels to fresh, usable condition. PRI Fuel Treatment's more complete combustion provides more power, more engine efficiency, and more operating economy with extended engine life. Injectors stay clean and long lasting. Fuel filters remain cleaner, reducing the risk of filter failure.

PRI improves Today's New Fuels:

PRI Fuel Treatments are laboratory tested and proven to protect against water separation in today's ethanol enhanced gasoline. Lubricity is added to ULSD for a better performing diesel, keeping diesel engines in top performance. Lower octane and cetane fuels can be used by adding PRI Fuel Treatments, thereby lowering operation fuel costs. Greater engine power when using new fuels will be a noticeable benefit.

PRI's Promise:

PRI Fuel Treatments are sold with a promise that the user will receive more value in PRI use than it costs to use PRI. If you are not completely satisfied with the performance of PRI Fuel Treatments, the manufacturer will cheerfully refund your purchase (see bottle for details).
