It reduces operating temperatures, fights varnish and acid formation, and maintains film strength across hot and cold extremes—making it suitable for a wide range of passenger cars, light trucks and fleet equipment that experience severe duty cycles.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Amsoil SVGPK protect gears during heavy towing and hauling?\u003c\/h3\u003e\n\u003cp\u003eThe lubricant forms a durable protective film that minimizes metal-to-metal contact under heavy loads, reducing wear and scuffing when gears and bearings are stressed.
