Why AMSOIL? | AMSOIL introduced the world's first synthetic motor oil for diesel engines in 1975. AMSOIL synthetic diesel oil was formulated to outperform conventional diesel oils on all counts. It was clear from the start that this innovative product would play a major role in engine performance and engine life.

Today, AMSOIL synthetic diesel oils are synonymous with power and performance. they're tough, reliable and they withstand the devastating effects of severe-service towing and heavy hauling that destroy lesser oils. By reducing friction and guarding against wear, AMSOIL synthetic diesel oils increase fuel economy and help keep vehicles on the job, saving you money.
