Four-wheel drive vehicles are often subjected to periods of heavy throttle application, towing and dirty, off-road driving. These harsh operating conditions mean four-wheel drive vehicles demand extra protection from a motor oil. AMSOIL synthetic motor oils are formulated with the most advanced chemistries available. High-quality base stocks combined with an exact blend of premium additives provide excellent protection and performance in the most demanding operating conditions.
AMSOIL synthetic motor oils not only run clean in high temperatures, they actually help hold down engine heat during high-stress operation. In cold temperatures, AMSOIL synthetic motor oils flow readily, providing dependable starting and quick post-startup protection.
Towing and travel over rough terrain put extra load on the engine. AMSOIL synthetic motor oils provide an extremely durable lubricating film, one that’s tough to break no matter how heavy the load. A robust package of anti-wear additives insures protection against accelerated wear during high-load operation. The shearing forces generated inside today’s high-RPM automobile engines can literally tear apart the molecules of conventional oils. AMSOIL synthetic motor oils, because of their unique synthetic construction, withstand shearing forces. AMSOIL motor oils resist thinning and viscosity loss better than conventional oils do.
The unbalanced hydrocarbon structure of conventional petroleum-based motor oils contains molecules of many different shapes and sizes. In high temperatures the lighter molecules tend to vaporize, leading to increased oil consumption, oil thickening and a loss of performance. AMSOIL synthetic motor oils resist burn-off during high- temperature, high-stress operation. Their pure, uniform molecules provide an unsurpassed level of stability, even under the most extreme operating conditions (See NOACK Chart).
Reduced maintenance costs through better protection, fewer new parts to buy and extended drain intervals save 4x4 owners hundreds, sometimes thousands of dollars every year.
Conventional motor oils tend to “boil off” in high temperatures. Vaporized oils grow thick and heavy. They circulate poorly, reduce fuel efficiency and contribute to excessive emissions and engine wear. Of course, oil consumption increases as oil boils off.
AMSOIL synthetic motor oils’ superior vaporization resistance keeps fuel economy high, oil circulation efficient, and oil consumption, emissions, and most importantly, engine wear, to a minimum. AMSOIL synthetic motor oils are formulated to allow engines to run smoother and easier, producing more power and performance and better fuel economy.
The primary function of oil is to prevent friction and wear. AMSOIL synthetic motor oils are made from the finest synthetic base stocks and most advanced additive packages.The uniform molecular structure of AMSOIL synthetic motor oils ensures their durability and effectiveness. The additives protect engines by bonding to metal surfaces and forming a protective film layer between moving parts that are vulnerable to friction and wear when an engine is first started and before the oil begins to circulate completely. AMSOIL synthetic motor oils provide outstanding wear protection in high-stress and heavy- load driving conditions.
Conventional oils oxidize in high temperatures, causing sludge and deposit build-up that decrease fuel efficiency, contribute to corrosion and increase engine wear. AMSOIL synthetic motor oils resist oxidation and thermal breakdown far better than conventional oils. Because AMSOIL motor oils’ synthetic formulation resists oxidation so well, they run naturally cleaner than conventional oils. AMSOIL motor oils have a superior detergent/dispersant additive package that, when tested after tens of thousands of miles of use in the crankcase, still exhibits of a lubricant. The smaller the average wear scar, the better the wear outstanding deposit control. protection provided by the lubricant.
AMSOIL Ea Air Filters (EaA) feature exclusive nanofiber technology that delivers more efficiency, higher capacity and optimum air flow. Nanofiber technology has been used exclusively in heavy- duty applications, including the US ARMY Abrams M1 tank.

North American diesel fuel is notoriously cetane-deficient. Often, the performance problems drivers blame on their diesel engines, like rough running and a lack of power, are actually caused by cetane-deficient diesel fuel. Instead of igniting smoothly, low-cetane fuel explodes, sending shock waves through the combustion chamber and throughout the engine.
AMSOIL Cetane Boost (ACB) (for use in all diesel engines) raises cetane three to seven numbers, helping engines start dependably and run smoothly and powerfully.
AMSOIL P.i. Performance Improver (API) ranks among the most potent gasoline additives available today.
