Keeps Fuel Fresh and Ready To Use – It’s a fact: fuel ages quickly! No matter how soon you use the gasoline you buy, it will have aged in your fuel tank by the time you use it; for that reason, you can’t afford to be without PRI-G. PRI-G keeps gasoline fresh. In fact, by treating the fuel annually with PRI-G, you can keep it fresh in storage for years! You’ll be assured a fast start for your engine next season, or whenever you use it next. Those operating a generator on a periodic basis are especially benefited by PRI-G use – when it comes time to run that generator, it’s fuel will be fresh and ready to go! If your fuel has already aged, PRI-G can still help. Tests have shown where PRI-G can restore aged fuel to refinery-fresh conditions.

Super Concentrated – PRI-G is super concentrated, treating fuel at a 1:2,000 ratio. This means PRI-G is extremely cost effective to use. Get the most out of your gasoline for only pennies a gallon!

Safe To Use – PRI-G’s enhanced thermal stability chemistry works within the fuel instead of altering it, which means the product is completely safe to use. Fuel specifications aren’t changed, so engine warranties are not voided! PRI-G is safe and effective in both four stroke and two stroke engines. Use PRI-G today to get the most out of your gasoline and your engine.
