Best Protection Around
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.
We engineer our synthetic diesel oils with the same passion and pride you put into your turbodiesel, providing protection you can depend on in the most severe operating conditions. Jump in and find out more.
ENGINE PROTECTION
A diesel truck is a serious investment – don’t skimp on protection. AMSOIL synthetic diesel oils provide the ultimate protection for your hard-working diesel engine, preserving the horsepower you crave and keeping you on the road.
Excessive wear to diesel cylinder liners and rings leads to increased oil consumption and loss of compression, reducing horsepower and fuel economy.
TURBOCHARGED PROTECTION
The extreme heat produced by turbochargers can be brutal on your oil. If your oil fails and your turbos are damaged, you start losing horsepower – or worse. Our synthetic diesel oils are designed to protect your horsepower. We build extra turbo protection into every drop, preserving turbos and delivering reliable horsepower.
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.

AMSOILWarranty
As millions of satisfied AMSOIL customers know, using AMSOIL synthetic lubricants or practicing extended drain intervals does not void new vehicle or equipment warranties. In recent years, however, some original equipment manufacturers (OEMs) have attempted to revive old fears about warranty coverage in an attempt to increase sales of their own, typically-more-expensive, OEM-branded oils.
AMSOIL Two-Million Mile Truck Story
In October 2012, AMSOIL told the story of Jerry Pruett’s one-million-mile-plus Kenworth. The Woodhull, Ill., native installed AMSOIL synthetic lubricants when he bought the truck new in 1999. After reaching 1.6 million miles on the original transmission and differentials and 1.1 million miles on the factory-rebuilt engine in 2012, Pruett has since eclipsed 2 million miles and shows no signs of slowing down.
