Product Description

AMSOIL 10W-40 High Performance Synthetic Motor Oil provides superior protection and performance in the most severe automotive driving conditions. AMSOIL 10W-40 High Performance Synthetic Motor Oil provides a wide range of protection in all four-cycle gasoline and diesel engines, including pickups, RVs, cars and off-highway vehicles. AMSOIL 10W-40 High Performance Synthetic Motor Oil is recommended for use in vehicles subject to stop-and-go driving, short trips, high temperatures, frequent trailer pulling and off-road use.

Resists High Temperature Vaporization

Conventional motor oils tend to “boil off” in high temperatures, losing up to 25 percent of their original weight. These vaporized oils circulate poorly, reduce fuel efficiency and contribute to excessive emissions and engine wear. AMSOIL 10W-40 High Performance Synthetic Motor Oil resists vaporization. In fact, according to the NOACK Volatility Test, which measures the weight loss of an oil due to evaporation, AMSOIL 10W-40 High Performance Synthetic Motor Oil only loses 7.0 percent of its weight in high temperature service, surpassing rigorous European standards set at 13 percent weight loss in high temperature testing. The superior vaporization resistance of AMSOIL 10W-40 High Performance Synthetic Motor Oil keeps engine wear, oil consumption and emissions to a minimum, while keeping oil circulation efficient and fuel economy high.

Resists Oxidation and Thermal Breakdown

Conventional oils oxidize in high operating temperatures, producing sludge and deposit build-up that contribute to corrosion, increased engine wear and decreased fuel economy. AMSOIL 10W-40 High Performance Synthetic Motor Oil resists oil breakdown, maintaining its cooling and lubricating properties and providing extended drain intervals. It continues to provide maximum protection at temperatures that oxidize conventional oils. The advanced heat transfer capabilities and high lubricity of AMSOIL 10W-40 High Performance Synthetic Motor Oil keeps engines running in their optimum temperature range for top performance and long life.

Provides High Shear Stability

AMSOIL 10W-40 High Performance Synthetic Motor Oil surpasses the North American SAE and European ACEA oil specifications for high temperature/high shear (HTHS) viscosity. It retains its viscosity at temperatures and loads that cause conventional oils to shear back to a lower viscosity. AMSOIL 10W-40 High Performance Synthetic Motor Oil maintains an extremely protective viscosity of 3.93 cP at 302°F (150°C) in the ASTM D 4683 High Temperature/High Shear Test, significantly exceeding test limits.

Provides Low Temperature Protection

AMSOIL 10W-40 High Performance Synthetic Motor Oil remains fluid at temperatures as low as -54°F (-48°C), permitting easy engine cranking for quick starts. During sub-zero temperatures, AMSOIL 10W-40 High Performance Synthetic Motor Oil flows to all parts of the engine much quicker than conventional petroleum oils, greatly reducing the rate of wear and increasing engine life.

Resists Deposit Formation

AMSOIL 10W-40 High Performance Synthetic Motor Oil is highly resistant to oxidation, running significantly cleaner than conventional motor oils. AMSOIL 10W-40 High Performance Synthetic Motor Oil has a superior detergent/dispersant additive package that, when tested after tens of thousands of miles of use in the crankcase, still exhibits outstanding deposit control.

Inhibits Rust and Corrosion

AMSOIL 10W-40 High Performance Synthetic Motor Oil contains special rust and corrosion inhibitors to protect iron parts, as well as copper, lead and aluminum bearing materials.

Provides extended Drain Intervals

AMSOIL 10W-40 High Performance Synthetic Motor Oil features a superior synthetic composition and advanced performance additives, performing much longer than competing conventional and synthetic oils. No other major oil manufacturer matches AMSOIL’s 25,000-mile or one-year drain interval recommendations.

Applications

AMSOIL 10W-40 High Performance Synthetic Motor Oil may be used in gasoline or diesel engines and is recommended for applications requiring the following specifications:

Mixing AMSOIL

AMSOIL 10W-40 High Performance Synthetic Motor Oil is compatible with conventional petroleum oils; however, mixing AMSOIL 10W-40 High Performance Synthetic Motor Oil with a conventional oil will shorten the drain period of AMSOIL 10W-40 High Performance Synthetic Motor Oil. Engine oil additives or after-market products are not recommended for use with AMSOIL 10W-40 High Performance Synthetic Motor Oil.

Service Life

If the vehicle is equipped with an AMSOIL Oil Filter, the filter should be changed at 12,500-mile or six-month intervals (whichever comes first) in gasoline engines. Non-AMSOIL oil filters should be changed at the engine manufacturer’s recommended filter change interval.
