Heavy Equipment,  Off Road & Construction

The superior performance and protection provided by AMSOIL synthetic lubricants adds up to increased productive time and profits.


Why synthetic? Because syn­thetic lubricants are superior to conventional petroleum lubricants. Petroleum lubes are refined from crude oil, a natural substance pumped from the earth and contain­ing diverse chemicals. Some of the chemicals in petroleum oil are detri­mental to the lubrication process and to the lubricated components. For example, some petroleum oil chemicals invite oxidation in high-temperature operations. Oxidation quickly destroys lubricant integrity.  

Synthetic lubes, on the other hand, are not refined from crude oil, but constructed from pure chemi­cals selected for their ability to lubricate. The purity of synthetic lubricant basestocks significantly reduces lubricant oxidation, which promotes the ability of synthetics to be used in higher temperature appli­cations than conventional lubes may be and promotes their ability to be used for extended drain intervals. In fact, AMSOIL synthetic lubricants are specifically formulated for extended drain intervals.  

Synthetics are also free of the paraffin’s found in conventional petroleum oils. With no paraffin to congeal at low temperatures, syn­thetics maintain better low-temper­ature fluidity than petroleum oils do, which protects equipment operating in cold environments — even the relative cold of a just-started engine.  

The precise blend of synthetic base stocks and high-quality additives promotes superior lubrication and friction reduc­tion, which in turn promotes superior heat control, wear control and energy efficiency. Molecu­lar uniformity also helps synthetics maintain their protective viscosity in high-temperature operations, which also promotes superior wear control.  


Diesel Motor Oils

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 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.



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.

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.

Reduced Downtime

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

Series 3000 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 out protects other popular diesel oils even 5W-30 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 5W­30 oil changed at 20,000­mile intervals.

AMSOIL CJ-4 oils retain there viscosity in the face of shearing forces. With a 4% fuel dilution AMSOIL delivered, while the competition failed. See the report here.

Gasoline Motor Oils

Construction vehicles are often subjected to periods of heavy throttle application, towing and dirty, off-road driving. These harsh operating conditions mean Construction 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 second-to-none protection and perform­ance in the most demanding operating conditions.

Clean All-Temp Protection

AMSOIL synthetic motor oils not only run clean in high temperatures, they actually help hold down engine heat during high stress operations. In cold temperatures, AMSOIL synthetic motor oils flow readily, providing dependable starting and quick post-startup protection.

Load 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 don’t thin out and lose viscosity like conventional oils do.

Power and Fuel Economy

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 skyrockets 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 allow engines to run smoother and easier, producing more power and perform­ance and better fuel economy.

Resist Oxidation

Conventional oils oxidize in high temperatures, causing sludge and deposit build-up that decrease fuel efficiency, contribute to corrosion and increase 0.4 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 outstanding deposit control.

Signature Series Motor Oils

Signature Series Synthetic Motor Oil delivers extraordinary lubrication in all types of automotive gasoline engines. Combining the industry-premier synthetic technology with AMSOIL premium additives, AMSOIL Signature Series Synthetic Motor Oil exceeds the higher performance demands of modern engines, withstanding the stress of higher horsepower, higher heat and complicated emissions control systems.

Resist Volatilization

The unbalanced hydrocarbon structure of con­ventional petroleum-based motor oils contains molecules of many different shapes and sixes. In high temperatures the lighter molecules tend to vaporize, leading to oil consumption, oil thickening, and loss of performance. AMSOIL synthetic motor oils don’t 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.    

Save Money

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.

Reduce wear

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 oil 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 the ultimate in wear protection in high-stress and heavy-load driving conditions.

Donaldson® Endurance™ Air Filters

Donaldson Endurance™ Air Filters with exclusive nanofiber technology offer longer engine life, longer filter life, initial efficiency up to 99.99 percent and five times more capacity.

The nanofiber technology causes submicron contaminants to be held on the surface layer of smaller fibers. This filtration characteristic is only possible with this new type of air filtration technology. In on-highway applications, where the contaminant is primarily submicron in size, Donaldson Endurance filters cause less restriction than conventional filters with cellulose media. The smaller interfiber spaces of nanofiber technology have a higher efficiency and capture more contaminant.

The following illustration may help visualize these phenomena: Imagine two filters, a chain link fence and a mosquito net, with a tennis ball being a dirt particle. As you may have observed, a tennis ball will fit quite nicely into an opening of a chain link fence, but will obstruct the hole almost 100%. Now imaging the same tennis ball covering a mosquito net. The tennis ball, at the point of contact with the netting, will obstruct much less filter area than the chain link fence example. In fact, air will flow around the tennis ball all the way to the point of contact. It will take many more particles to obstruct the netting surface area than the chain link fence.

Donaldson Endurance™ air filters are guaranteed to deliver twice the miles between change intervals over cellulose air filters for on-highway applications or customers receive a new filter at no charge.
