Complete Gasoline TreatmentPrice subject to change.

PRI-G is the fuel treatment product line from Power Research Inc., a Houston-based specialty chemicals company. The brand's signature product — PRI-G for gasoline and PRI-D for diesel — uses proprietary refinery-grade additive chemistry developed for industrial and military fuel storage applications before reaching the consumer market.
The products are positioned as premium-tier stabilizers targeting serious preppers, boaters, classic-car collectors, and equipment owners who need multi-season storage reliability rather than the commodity one-season protection typical of mass-market stabilizers.
