It reduces fuel pump wear by up to 45%, prevents sludge buildup, and lowers harmful emissions, making it an essential product for emergency preparedness and long-term diesel maintenance. ## Description Emergency diesel fuel can degrade over time. Storing diesel fuel with PRI-D diesel treatment will prolong the storage time of your emergency fuel and can actually restore diesel to refinery freshness if needed.Power Research Inc PRI-D diesel treatment is ideal for emergency diesel fuel treatment. It increases the lubricity of your fuel, keeps tanks and fuel lines sludge free, and improves engine performance.For an emergency preparedness minded person, the value of PRI-D cannot be calculated. This diesel treatment product keeps fuel at peak stability levels and prevents fuel degradation during long-term storage. This is important because one of the most common failures of emergency equipment is bad fuel that has been stored too long.Another key benefit of PRI-D is extended life of fuel pumps. Due to the high lubricity of this additive, wear reduction on ULSD fuels can be reduced by up to 45 percent. This can really reduce maintenance costs.PRI-D reacts with fuel upon contact, providing greatly enhanced fuel lubricity & deposit control benefits demanded by today’s engines. The laboratory & field proven benefits are multiple:● Peak firing pressure (pmax) is boosted as much as 4 bar● Specific fuel consumption is reduced as much as one percent● Carbon & fuel system deposits are inhibited● Fuel injection pump wear is reduced as much as 45 percent● Fuel stays fresh, ignition quality improved. Degraded fuels are restored.● Tanks & fuel lines remain free of slime & sludge● Carbon monoxide (CO), unburned hydrocarbons (HC) & particulate matter(PM) are significantly reducedImproved Performance, Maintenance, & Emissions Reductions– CARB/EPA & power plant testing verifies PRI-D capability to improve the combustion process for optimum, long-term engine performance & efficiency & emissions reduction.
