You’re not tooling around town in a short-box whose heaviest load was that one time you went too far at the local wholesale club – you’re in a diesel. It’s raw power and whether you’re impressing your buddies or towing the work trailer, you need every ft.-lb. of torque. Pushing your pickup to perform might be a natural side-effect of sitting in the driver’s seat, but it also puts a lot of stress on your engine. And let’s face it – they aren’t giving these things away. Your investment deserves a diesel oil that’s up to the challenge. Your investment deserves AMSOIL.
More Built-In Diesel Engine Protection
Excessive wear to diesel cylinder liners and rings leads to increased oil consumption and loss of compression, reducing horsepower and fuel economy.
Independent testing shows AMSOIL Signature Series Max-Duty Synthetic Diesel Oil provides 6X more wear protection than required by the standard*. In the same test, AMSOIL Heavy-Duty Synthetic Diesel Oil delivers 4X more protection against wear than required by Detroit Diesel’s standard*.
More Built-In Protection
Operating at up to 150,000 rpm in temperatures that exceed 1,000°F, a turbocharger on a stock engine can dish out a lot of punishment to your oil. If it’s not formulated to take the beating, the oil can break down, creating deposits and wear. For some, stock engines don’t provide enough power, but dropping a tune on your engine puts even more stress on both your turbo and your oil.
Top-Grade Protection Against Deposits
Deposits caused by high turbo temperatures can lead to a host of problems, the most critical of which is bearing failure. Hot exhaust gases spin the turbine and expose that bearing to extreme heat. Your oil has to be up to the task of effectively removing heat from the bearing while providing proper lubrication to keep it spinning at high rpm. When your oil breaks down, excessive deposits form on the bearing and shaft that lead to a downward spiral for the longevity and effectiveness of your turbo.
AMSOIL Heavy-Duty Synthetic Diesel Oil is built to withstand the punishment turbos dish out, protecting against deposit formation in extreme temperatures. AMSOIL Signature Series Max-Duty Synthetic Diesel Oil provides protection boosted to the max, delivering up to 60 percent better turbo cleanliness* and withstanding the extra demands you place on that turbo when pulling heavy loads or updating the tune for maximum horsepower.
We deliver nothing but premium synthetic lubricants designed to help you get the most out of your turbocharged diesel engine.
