# Amsoil Heay Duty Anti-Freeze and Coolant Long Life Formula (3.78l)

# Industrial Strength. Million Mile Protection.

Amsoil Heavy-Duty Antifreeze & Coolant is a professional-grade formulation designed specifically for diesel trucks, heavy machinery, and industrial generators that require protection against cylinder liner pitting.

Heavy diesel engines face a unique threat: **Cavitation.** The intense vibration of a diesel engine causes air bubbles to implode against the cylinder liners, pitting the metal and eventually drilling a hole right through the engine block. Standard green coolant cannot stop this. Amsoil Heavy-Duty is heavily fortified with organic acids and inhibitors to coat the liners, preventing cavitation and keeping your fleet or generator running for up to 1,000,000 miles or 20,000 hours.

Stops Liner Pitting Formulated specifically for "wet sleeve" diesel liners. It provides a robust protective layer that withstands the violent vibrations of heavy-duty engines without needing frequent SCA additives.

1 Million Mile Life Engineered for extended service intervals. Ideal for logistics fleets (Hino/Isuzu) where downtime for coolant changes costs money. Lasts 8 years, 20,000 hours, or 1,000,000 miles.

Generator Ready The ultimate choice for Caterpillar, Cummins, and Perkins generators used during load shedding. It handles the extreme heat soak these static engines experience better than standard water.

Anti-Scale Technology Pakistan's hard water destroys radiators. Amsoil's poly-organic acid technology prevents minerals from precipitating out, keeping radiator tubes flow-efficient.
