Even the cleanest, most refined fuels operating new engines contain hydrocarbons which form agglomerations of gums, resins, and carbon during combustion. This leads to engine problems, less power and fuel efficiency, and engine wear and breakdowns.

ESI provides a product which prevents this buildup from occurring. PRI-D, developed by Power Research Inc., works effectively with the ESI Clean Fuel System™ to inhibit carbon deposits, remove slime and sludge, stabilize fuel and extend its storage life, and prevent tank erosion. In addition, the engine exerts more power more efficiently, and with less smoke.
