Use High-Quality Antifreeze to Guard Against Cooling-System Problems

Antifreeze/coolant is critical to proper engine operation, but it’s often overlooked when performing preventative maintenance. One reason is many motorists simply don’t understand the importance of a properly functioning cooling system to maximum engine performance. Another reason is the confusion surrounding the different “colors” of coolants on the market and the problems that result from mixing incompatible coolants. 

What is Antifreeze/Coolant?

Like motor oil, antifreeze/coolant consists of a base component mixed with additives. The base, either ethylene glycol (EG) or propylene glycol (PG), helps lower the freeze point of water to protect the engine during winter while raising the boiling point of water to help prevent engine overheating in the summer.

AMSOIL Antifreeze/Coolants

AMSOIL offers three coolants, all of which offer a unique blend of organic acids. AMSOIL uses di-acid technology, which means both ends of the organic acid are active. This makes them work faster and form stronger bonds for enhanced protection.
