Fluids, Oils and Filters for Diesel Trucks

Synthetic Lubricants and Fluids for Diesel Engines

You ask a lot of your truck, and you expect it to answer. Whether you are a weekday warrior, on the work-site, towing your equipment, or a weekend warrior bringing your toys or family for a weekend of fun, you rely on your truck and need the best in power, protection and performance.

The term “diesel” still conjures a host of negative connotations to some: loud, smelly, smoky, dirty... Such unflattering descriptions may have been apt years ago, but those in the know realize today’s diesels no longer fit the stereotype. And judging by the numbers, increasingly more drivers are discovering the truth about diesels.

“Clean diesel” is a term automakers use to distinguish today’s cleaner, quieter diesels from their loud and smoky predecessors. Technically, a clean-diesel engine is no different from any other diesel engine. The differences lie in the fuel they use and their sophisticated exhaust-treatment devices.

AMSOIL Synthetic Diesel Oils are designed to withstand the punishment doled out by diesel engines. They provide excellent protection during heavy use and even abuse. They reduce friction and wear better than conventional oils, helping hard-working diesel engines perform better and last longer.

They withstand high-temperature breakdown to help prevent harmful deposits from forming while remaining fluid in sub-zero temperatures for easier cold starts and faster circulation compared to conventional oils. The advanced lubricity also increases fuel economy.

The Ultimate in Power, Performance and Protection for Hard-working Diesel Engines !

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*.

Signature Series Diesel Oil Provides 6X more Wear Protection

AMSOIL Provides Top-grade Performance for Turbocharged Diesel Engines !

Hard-working Turbocharged Diesels can literally tear engine oil apart. Elevated heat and shearing forces can thin the oil until it fails to provide adequate protection, leaving components susceptible to wear and failure.

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.

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 and Max-Duty Synthetic Diesel Motor Oils

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. The full line of AMSOIL Synthetic Diesel Oils withstands the punishment of both modern and older turbo diesels.

The best Full Synthetic Oil for Engine Builds

AMSOIL Protects Your Hard-working Transmission

AMSOIL Synthetic Transmission Fluids withstand the rigors of high-horsepower, high-torque diesels better than conventional fluids. When you're running hard, towing or climbing hills, your transmission generates heat. If your transmission fluid can't handle the heat, its ability to protect against wear is compromised.

Extreme heat generated when towing and hauling destroys inferior transmission fluids and shortens transmission life. Heat is especially harmful in today’s smaller transmissions that hold less fluid but are required to direct increased power and torque.

Inferior transmission fluids coupled with severe-service driving can lead to fluid leaks, poor shift quality and expensive transmission repairs. AMSOIL synthetic transmission fluids resist extreme heat to keep gears, bearings and seals protected in the toughest driving conditions.

AMSOIL Synthetic Transmission Fluids maintain viscosity for reduced wear; resist oxidation and sludge build-up for superior cooling and lubrication. So you can tow, haul, plow or just plain drive hard longer between fluid changes with complete confidence that your transmission is protected.

AMSOIL Protects Your Differentials from Thermal Runaway

Too often Differentials are out of sight, out of mind. However, towing and heavy hauling focus intense pressure on the ring-and-pinion gears, inviting wear.

Synthetic Gear Lubricants for Differentials

The intense heat build-up in differentials causes gear lube to thin, reducing viscosity and further increasing heat in a cycle known as thermal runaway. Left unchecked, thermal runaway can shorten component life and lead to catastrophic failure.

AMSOIL Severe Gear® 100% Synthetic Gear Lube delivers high film strength to protect against wear and outstanding heat resistance to guard against thermal runaway.

Extreme-pressure formulations guard against metal-to-metal contact for maximum wear control.

Their full synthetic chemistries reduce friction and drag for increased fuel efficiency while providing extended drain intervals for the convenience of longer-lasting fluids.

AMSOIL Diesel Fuel Additives

With AMSOIL Diesel Fuel Additives, you can be certain that the fuel in your tank is the best it can be. Diesel fuel quality varies. Bad fuel fouls injectors, accelerates injector pump wear, makes for tough running engines, impedes starting and causes engine stalling. You can't always be certain of the quality you're getting at the pump.

With variable diesel fuel quality at the pump and today’s sophisticated fuel-delivery systems, it doesn’t take long for performance issues to surface. The best defense is a good offense.

Fuel system performance is critical to getting the most out of your diesel, and modern high-pressure common-rail (HPCR) designs just add to the challenge. Fuel economy and performance are highly dependent on getting the right amount of fuel into the combustion chamber in the correct physical form at the correct time.

Plus, today’s ultra-low-sulfur diesel (ULSD) doesn’t have the lubricating properties diesel fuel once had, inviting fuel pump and injector wear. Highly concentrated AMSOIL diesel fuel additives are designed to maximize fuel-system performance and life, helping prevent expensive repairs and injector replacements in all types of diesel engines, including HPCR.

AMSOIL Diesel Fuel Additives are specifically designed to treat specific performance issues and ensure that you have maximum diesel performance. Why wait until your diesel is in trouble before doing something? Be proactive with the AMSOIL diesel additives family.
