Unstabilized diesel fuel has a very short storage life. The best part of the fuel rapidly evaporates, and what's left degrades into a substance that can quickly gum up fuel injectors, valves, sensors, filters and other components, reducing performance and eventually causing complete machine failure.

PRI fuel stabilizer dramatically extends diesel fuel storage life, and enhances overall performance. PRI is an industrial grade product and is far more concentrated than competing brands. The higher concentration level of PRI allows much better distribution efficiencies, which means your cost per treated gallon is much lower with PRI. The pint container treats 256 gallons of diesel, and the quart container treats 512 gallons.

Routine usage: It pays to treat all your fuel with PRI. Whether it's for your backup generator, your vehicle, or seasonally-used machines like mowers, snow blowers, garden tillers and recreational vehicles, PRI makes it easy and economical to preserve the full value of your fuel, and keep your equipment running at peak performance and efficiency! We use PRI fuel treatment, and we recommend it highly to our customers.

“I’m in the PNW after crossing from the other coast. When I found what I needed at Pleasant Hill, a sense of location and reference point was regained! Here I found a ‘smart’ catalog with both quality products and excellent people. Pleasant Hill is a refuge, a gem, in these times!”

Kerosene too: PRI-D works equally well to preserve the quality of stored kerosene (for long storage always start with K1 grade kerosene.)
