PRI-G 32 oz. Treats 512 gallons

PRIG is meant for Gasoline, Ethanol, E10 and E15 fuels. What is an E10 and E15 fuel? E10 and E15 are blends of ethanol and gasoline—the number after the “E” is the percentage of ethanol by volume.

PRI-G is also good for gasoline yard tools and small engines, but it cannot be used as a substitute for PRI-D diesel fuel. PRI-D is meant for Diesel and Kerosene, but can be used in an emergency to treat gasoline and ethanol fuel.

Emergency power is a critical life line when a disaster strikes. Experience shows when a disaster strikes fuel stored for an emergency has often been neglected and left to deteriorate allowing it to become unusable for an emergency. The use of such fuel when called upon during a disaster or an emergency has the potential to disable engine components plugging filters, carburetors, injectors and in some cases the fuel deteriorates so much the fuel will not ignite.

The neglect to treat fuel for long and perhaps shorter term storage is one of our weakest links in disaster preparedness. It is estimated that more than one half of the power generator failures that occur can be directly related to fuel degradation. This also applies to infrequently used vehicles and small engines.

Stored fuel can be preserved and insured against deterioration and failure to perform by simply applying a small amount of PRI-D or PRI-G at the time of storage. Implicating the proper use of PRI fuel treatment will help the fuel remain fresh and stable. This freshness will hold for months if not indefinitely when the fuel is periodically re-treated with industrial grade PRI fuel treatment.

Power Research Inc. is the industries leader for preserving fuel and its integrity for emergency power systems. PRI-D and PRI-G have widespread track records for operations of data facilities, hospitals, office buildings, fire departments, radio and television stations, cell phone sites, standby generators at nuclear power plants and even home storage for small engines such as lawn mowers, tillers, weed eaters, chain saws etc.

PRI-G Industrial Grade Gasoline/Ethanol Treatment

For E-10 and All Gasoline Grades (cannot be used for a substitute for diesel treatment)


PRI-G is a super concentrated, complete fuel treatment that improves any type of gasoline, including the latest E-10 blends, enabling them to perform to maximum potential. PRI-G’s industrial strength, enhanced thermal stability chemistry reacts with fuel upon contact, and provides multiple benefits:

  • Engines perform better and last longer
  • Engine power increased and fuel economy realized
  • Fuel system and engine deposits prevented
  • Phase separation inhibited for E-10
  • Fuel stays fresh and ready to use
  • Degraded fuel is restored to freshness
  • Hesitation, knocking, and pinging reduced

(PRI) Power Research Inc is the WORLD’S LEADER and is the most EFFECTIVE FUEL TREATMENT, STABILIZER and ADDITIVE if you are facing a challenge with your fuel, it is highly likely that PRI-G or PRI-D can help you overcome it! PRI is the industry leader for restoring old, aged and stale fuels. PRI can restore or bring back to life most gasoline and diesel fuels of the worst condition.

Will PRI remove water?

PRI will absorb and emulsify small amounts of water in fuel, but the larger amounts of water should be removed by a professional tank cleaning company, followed by treating the fuel with PRI. Water droplets in fuel during combustion can be harmful to your engine?

How long will PRI keep?

PRI will keep fuel fresh for at least one full year after initial treatment fuel and can stay fresh for years to come with annual retreatment. PRI treated fuel has been known to remain fresh for extended periods of time, but annual inspection of the fuel is recommended.

Does PRI work with other additives?

There is no harm in combining PRI and other additives. However, PRI cannot guarantee its effectiveness when it is combined with other additives. For effective, maximum result, use PRI alone in your fuel and at the proper ration.

How should I use PRI?

PRI should be dosed into your tank no more than 10 minutes prior to fueling. For the initial PRI treatment, administer enough PRI for the entire fuel tank capacity, followed immediately by completely filling the tank. The fueling process provides enough agitation to properly mix and activate PRI. For continued use, add the proper amount of PRI needed to treat the amount of fuel you are adding to your tank, and then fill your tank with fuel. You do not need to repeatedly treat the entire tank. Use PRI at every fueling for maximum product satisfaction.

Is PRI-G for small engines different from regular PRI-G?

PRI-G for small engines is exactly the same as regular PRI-G. It was formulated with a different treatment ratio to make treating smaller tanks easier for you.
