Coolants & Coolant Additives

Gratta Oil's decision to offer Amsoil coolant and coolant additives is with good reason. If you want the ultimate in maximum performance in a coolant and are environmentally conscious, Amsoil Coolant is for you.

The Amsoil coolant formula provides a very long life fluid of 250,000 miles or 7 year service for automobiles and light trucks, and 750,000 miles or 7 year service for over-the-road vehicles. It is far less toxic than conventional anti-freeze, is biodegradable unlike other formulations, and considerably safer to humans, pets and wildlife than ethylene glycol based antifreezes. The toxicity of Amsoil's propylene glycol based coolant is so much less toxic than conventional antifreezes it is actually classified as "non-toxic". Click on "more information" to learn more.

Amsoil "Dominator" Coolant Boost enhances heat dissipation, transferring heat away from critical engine components and reducing operational temperatures even further than would be realized from running straight water or coolant. Use Amsoil Coolant Boost to obtain optimum cooling performance.
