It is actually the Phosphorus that has to accompany the Zinc to make it work properly as an anti-wear agent. The Phosphorus is the heat seeking agent that over time can react with the precious metals (Platinum, Palladium and Rhodium) within the CAT and damage it to the point of improper operation. Current automobiles need a CAT Safe additive that will, most importantly, increase wear-protection without harming emission equipment that is very costly to replace. SR-1 Oil Treatment not only increases wear-protection but, will also increase fuel mileage with additional proprietary friction fighting components.

One bottle of SR-1 A2Z Oil Treatment is designed to add to 5-6 quarts of any API-SM rated oil that is being used in a catalytic converter equipped automobile. SR-1 A2Z Oil Treatment will bring the anti-wear capabilities of your oil up to a sufficient level.
