AMSOIL How It Is Made
AMSOIL For Any Engine
Cold Pour Test: AMSOIL Synthetic Oil versus Conventional Oil
Neglected Small-Engine Equipment

Diesel engines have been around since the dawn of the automotive era. Over the years, diesels have become the engine of choice for powering heavy-duty trucks, buses, agricultural vehicles, off-road equipment, hard-working pickup trucks, stationary generators, welders, and other equipment using compact diesel engines

To choose the right synthetic diesel oil for your small diesel powered equipment, use the viscosity grade(s) recommended by the original equipment manufacturer (OEM) for the life of the engine. Viscosity grades are primarily recommended according to the expected ambient temperatures, particularly the starting temperatures.

Engine oil operating temperature does not change significantly even in different ambient temperatures, so the recommended viscosity is quite consistent for various applications. The main difference is the viscosity grade "W" which relates to the starting temperature, as this will determine the lubricant viscosity, its pumpability and readiness to lubricate the engine.

Select from a list of our most popular synthetic diesel motor oils including Premium Protection, Original Equipment, Heavy-Duty Diesel and Marine Motor Oils.
