AMSOIL synthetic diesel motor oils help decrease downtime and increase profits with better protection and less expense.

Wear Control

AMSOIL synthetic diesel motor oils have been proven to keep wear rates lower than conventional oils. Synthetic base stocks are tailored to reduce friction more effectively than conventional base stocks, which lowers wear rates and helps keep engine heat from climbing excessively. Outstanding quality antiwear additives protect surfaces from wear in conditions that prevent a full lubricating film from developing.

Acid Neutralization and Soot Control

AMSOIL synthetic diesel motor oils are 12 Total Base Number (TBN) oils and are proven to neutralize acids and control corrosion for longer periods than conventional oils. The top-quality detergents responsible for long-term acid neutralization also inhibit deposit formation on hot engine surfaces. The highly effective dispersants in AMSOIL synthetic diesel motor oils control soot and other contaminants, providing long-lasting protection against wear and sludge formation.

Low Temperature Fluidity

AMSOIL synthetic diesel motor oils remain fluid in low temperatures. Low temperature fluidity helps engines start in cold temperatures and ensures rapid cold-temperature post-startup protection.

Chemical and Physical Stability

AMSOIL synthetic diesel motor oils offer superior thermal, oxidative and shear stability. Thermal stability allows them to work in high temperatures without undergoing molecular breakdown and consequently increasing oil consumption and starting the formation of sludge. Oxidative stability allows them to work in high temperatures without undergoing chemical changes leading to oil thickening, loss of lubricating ability, and sludge and acid formation. Shear stability keeps them from falling out of viscosity grade and losing their ability to protect against metal-to-metal contact and wear in engine operating temperatures as a result of shear forces.

Fuel Economy

AMSOIL synthetic diesel motor oils have a low friction coefficient that improves fuel economy by reducing the loss of power to friction. Fuel economy increases of five percent are common with AMSOIL synthetic diesel motor oils.

Extended Drain

Intervals Fleet demonstrations show AMSOIL synthetic diesel motor oils protect engines more effectively for extended drain intervals than conventional oils do for conventional drain intervals. Essentially, AMSOIL synthetic diesel motor oils protect engines better longer. Many truckers use AMSOIL synthetic diesel motor oils indefinitely, using oil analysis as their guide to oil changes.

Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil

AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, formulated for diesel and gasoline engine use, offers a combination of engine protection and fuel economy unmatched by other oils. Independent lab tests show Series 3000 outprotects other popular diesel oils – even 15W-40 grade oils - by a wide margin.

Series 3000 Improves Fuel Economy

Testing performed by an independent facility showed that class 8 trucks with AMSOIL Series 3000 in the engines and AMSOIL synthetic lubricants in the drivetrains obtained up to 8.2 percent more mpg than matched trucks lubricated with conventional products.

It’s a Proven Long Drain Oil.

An ongoing Class 8 fleet demonstration shows Series 3000 used continuously for 80,000 miles offers better TBN and viscosity retention, soot control and wear prevention than does a popular conventional 15W-40 oil changed at 20,000-mile intervals.

Synthetic 15W-40 Heavy Duty Diesel and Marine Oil AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil has been proven superior to conventional oils in fleet demonstrations and countless miles of over-theroad use. AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil reduces wear rates, provides extended drain service and saves truckers significant money.

	15W-40 Synthetic Blend Gasoline & Diesel Motor Oil AMSOIL Synthetic Blend Gasoline and Diesel Motor Oil offers the advantages of a synthetic at a more affordable price. AMSOIL Synthetic Blend Gasoline and Diesel Motor Oil provides high and low temperature protection, thermal and oxidative stability and retention of TBN, dispersency and viscosity.

Synthetic 10W-30/SAE 30 Diesel Motor Oil AMSOIL Synthetic 10W-30/ SAE 30 Diesel Motor Oil offers high and low temperature service and protection. Its low temperature fluidity is superior to that of conventional 15W-40 motor oils. Its shear stability, low volatility and high temperature film strength make it ideal for highstress applications.

AMSOIL Synthetic 5W-40 Premium Diesel Oil AMSOIL Synthetic 5W-40 Premium Diesel Oil is the premium choice diesel oil for model year 2007 and newer heavy-duty and pickup truck diesel engines requiring API CJ-4 emission quality oil standards.
