When Diesels are a Way of Life

Turbo Diesels

Get the Best Performance from Turbo-Diesels

Quarter-mile pulls at the track. Stoplight-to-stoplight acceleration. Effortless hauling under maximum payload. For enthusiasts, a turbo-diesel truck is a way of life, not just a vehicle. Squeeze the ultimate performance from your heavy-duty pickup truck by treating it to the best in lubrication and additives, bumper to bumper. AMSOIL is the industry leader in lubricants and treatments to put power-robbing problems in the rear-view mirror.

Performance Motor Oil Selection

The most basic of maintenance items on a diesel engine is an oil change, but it’s incredibly important for high-performing diesel engines. Whether you drive a bone-stock Chevrolet Silverado with the Duramax turbo-diesel engine, a Ford Super Duty powered by a 6.7 Powerstroke, or a Dodge with a 6.7 Cummins turbo diesel, protect it with AMSOIL Signature Series Max-Duty Synthetic Diesel Oil.

Why is AMSOIL the best? It’s tested to deliver six times the wear protection compared to conventional oil and better prevents wear on cylinder liners. AMSOIL also keeps your turbo cleaner and has the staying power to withstand demands for extra power, consistent heavy loads, and extreme strain. And in testing, AMSOIL prevents rust better than anyone else.
