That's where we come in. My company, Power Research Inc., manufacturers industrial-grade fuel stability chemistries for long term fuel storage for diesel and gasoline. The original formulas were developed for refineries more than 40 years ago for bulk fuel storage, and today, our ongoing research program has developed optimum formulas that can extend the life of today's modern fuels for many years at a time.
How long can PRI keep fuel fresh? This depends on the original condition of the fuel. While tests indicate that PRI can keep fuels fresh in many instances for 10 years and more, fuel should be dosed with PRI every 6-12 months for maximum benefit. If your fuel is already in poor condition, not to worry. PRI-D for diesel, and PRI-G for gasoline have also demonstrated an uncanny capability to restore very old, stale fuels to a refinery fresh conditions.
In one extreme case, a doubting client took a 15-year old sample of some very gummy and malodorous gasoline from a junkyard car in New Hampshire. He sent the sample to Saybolt Laboratories in Boston for analysis. Predictably, the fuel was completely unusable when tested for oxidation stability. When treated and re-tested with PRI-G, this bad fuel was completely restored to refinery freshness.
We recently had another similar case with a Caribbean-based client. The engines for his back-up power generation unit simply would not run on the stored fuel. We had the fuel tested for accelerated stability at an independent laboratory at Port Everglades, Florida. This fuel was out of specification by more than fifteen-fold--the worst I have ever seen in my 25-years of fuel experience. Again, PRI-D did the job. After treatment, this very challenging diesel fuel was brought into specifications. Our client's engines ran as if nothing had happened.
The key to PRI chemistry is our proprietary enhanced thermal stability chemistry. This unique chemistry is not available in the "consumer" additives at auto parts stores and marine and RV supply outfits. We've had many of these products independently tested, and not surprisingly, the majority of these "stabilizers" do little or nothing to preserve fuels. Some even make the fuel worse. The fact that some manufacturers heavily dilute these formulas with common solvent carriers--reducing their strength--is evidenced by the poor treatment rates of these products. This also makes them very expensive on a per treated gallon basis.
