Availability Out of stock


PRI-D gal treats 2000 gallons – PRI-D 32 oz treats 512 gallons – Diesel/Kerosene



PRI-D is a super concentrated, complete diesel fuel treatment for refiners, suppliers and commercial diesel consumers that improves all standard distillate grades, and is especially formulated to overcome the degraded lubricity and thermal stability characteristics of severely hydrotreated 0.1% MGO marine fuels and ultra low sulfur (ULSD) diesel fuels.

First, the refinery grade lubricity additive package of PRI-D provides a maximum level of effective lubricity protection at the 1:2000 dose rate for all fuel delivery systems.

SecondPRI-D Gallon is formulated with PRI’s exclusive thermal stability technology, essential to improving performance of modern, hydro treated distillate fuels.

PRI-D Gal – Do diesel fuel additives work?

PRI-D reacts with fuel upon contact, providing greatly enhanced fuel lubricity and deposit and emissions control benefits demanded by today’s engines. The laboratory and field proven benefits are multiple.

  • Fuel injection pump wear is reduced as much as 45 percent
  • Fuel pump plunger sticking is avoided
  • Engines and GTs perform better and last longer
  • Carbon and fuel system deposits are prevented
  • Fuel stays fresh, ignition quality is improved. Degraded fuels are restored
  • Visible smoke opacity and soot fouling is dramatically diminished

Improved Performance, Maintenance, and Emissions Reductions – CARB/EPA testing verifies PRI-D capability to improve the combustion process for optimum, long-term engine performance and efficiency. In test after test,

PRI D is verified to reduce unburned hydrocarbons, carbon monoxide (CO), particulate matter (PM) and oxides of nitrogen (NOx).

Maximum Lubricity Protection – The refinery-grade lubricity additive package of PRI-D is the most effective and safest available today based on extensive oil industry research, field performance experience and HFRR testing. Fuel pump wear is reduced as much as 45 percent. Costly and unsafe catastrophic pump failures are avoided.

Keeps Fuels At Peak Stability – PRI-D Gallon not only prevents fuel degradation in long-term storage, degraded fuels are restored to refinery freshness. PRI D is especially effective in providing the enhanced thermal stability that modern hydrotreated distillate fuels lack. PRI D capability is repeatedly confirmed in independently conducted ASTM D2274 testing.

Super Concentrated & Safe – PRI-D is super concentrated and cost effective, treating fuel at a 1:2,000 ratio (500 ppm). PRI-D contains no potentially damaging cetane improvement additives or harsh solvent chemistries, meeting all major engine manufacturer fuel specifications.

Dosage Rate:

PRI-D Gallon is dosed at the rate of 1:2000 (500ppm), regardless of fuel specifications under ASTM D975. The fixed dosage rate was developed in consideration of the fact that diesel fuel characteristics can be widely variable, and those quality standards, as proscribed under ASTM D975 do not completely account for all deficiencies associated with fuel performance.

Hence, optimal protection for fuels deficient in lubricity and thermal stability characteristics is ensured at the 1:2000 dosage rate.

Dosage Method:

Power Research Inc. recommends dosing of PRI D at the main bunker manifold by means of a safe and easily operated air driven gear pump arrangement. However, PRI-D is highly miscible with diesel fuel and may be also be added directly to tanks no greater than 20 minutes prior to fuel addition. Agitation from fuel flow into the tank typically provides a sufficient mixture.

Quality control:

PRI D is manufactured in accordance with strict, chemical manufacturing standards. Each blend is numbered, and a retain sample is FTIR tested against a laboratory standard to ensure optimal conformance.


PRI-D is a highly complex blend of organic chemistries when blended with diesel fuel will not stratify or separate, even with fuel purification. In fact purification systems remain cleaner and more efficient when processing PRI-D treated fuels.
