AMSOIL Passenger Car/Light Truck Antifreeze & Coolant 50/50 Premix - 1 Gallon Jug

AMSOIL Passenger Car/Light Truck Antifreeze & Coolant 50/50 Premix is a premium ethylene glycol coolant engineered for domestic and import passenger cars and light trucks. AMSOIL says its unique poly-organic acid OAT formulation is designed for broad vehicle compatibility and to exceed OEM requirements.

Designed to provide long-lasting cooling-system protection, this coolant helps protect against corrosion, freezing, boil-over, and scale buildup while keeping cooling systems clean. AMSOIL also states it is pre-mixed 50/50 with high-purity water and protects cooling system metals, gaskets, and hoses.

Built for daily-driven street vehicles, this coolant is ideal for customers who want a premium replacement coolant with long service life and broad compatibility. AMSOIL says it is compatible with all other antifreeze and coolant colors, though mixing different chemistries can make freeze protection harder to predict.
