AMSOIL Motor Oils
Unbeatable Lubrication

 Learn the facts that the 4x4 manufacturers and the oil industry don't want you to know!

The 4x4 manufacturers need to sell you 4x4's, that's their business. Each 4x4 maker has product planned obsolescence built into their business plan. They won't tell you about or recommend AMSOIL because your 4x4 engine would last twice as long, that's not in their business interest! Also they make a tremendous profit on the 10 cent OEM oil that they sell (that's what it costs to manufacture). This OEM oil provides two functions, it keeps your 4x4 on their planned schedule for repairs and wearout and it adds a tremendously profitable add-on sale. So recommending an oil that would make their 4x4 last longer and reduce their oil sales would be counter-productive to their business plan.

Extensive periods of heavy throttle application, towing, even stop and go driving make engines run hot.

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 flowreadily, providing dependable starting and quick post startup protection.

Technical Properties of AMSOIL Motor Oils

Load protection - Towing and travel over rough terrain put an 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. Know the facts! AMSOIL saves money.

Power and fuel economy - Super smooth AMSOIL synthetic motor oils help engines put through more power than they do with other oils. That saves fuel and boosts power and performance.

Unbeatable Filtration
                                                                            

AMSOIL Air Filters- Superior dirt contaminant and air flow make AMSOIL foam air filters the best choice for wear control and performance, especially off-road. Convenient and cost effective, AMSOIL air filters are reusable. Superior to all others, for more info click here.

AMSOIL Oil Filters- Featuring a unique, rugged, cellulose and synthetic glass fiber element, AMSOIL full Flow Oil Filters provide 35 percent more filtering capacity and 30 percent longer life than conventional oil filters. Amsoil oil filters filter 4 times smaller particles than conventional oil filters. For more info click here.

By-Pass Oil Filter- The AMSOIL By-Pass Oil Filter enhances oil and engine life by keeping oil analytically clean. Even the water and ultra fine particles that escape conventional oil filters are no match for the AMSOIL By-Pass Oil Filter. Click here for more details.

AMSOIL Dual Remote - An AMSOIL Full Flow and an AMSOIL By-Pass on a single mount which may be placed anywhere in the engine compartment for maximum filter changing convenience.

AMSOIL Gear Lubes

AMSOIL synthetic gear lubes deliver the rugged protection 4-wheel drive differentials and manual transmissions need.

Power and fuel economy - Low friction AMSOIL synthetic gear lubes maximize power output and minimize heat build-up. They lose less energy to friction than other lubes do. With AMSOIL, fuel energy is used for maximum 4-wheel drive power and top fuel economy.

Load protection - AMSOIL synthetic gear lubes bear the brunt of high-load stress so gears don't. AMSOIL synthetic gear lubes' naturally high film strength and tough extreme pressure agents shield components from premature wear.

All-season performance - High viscosity index AMSOIL synthetic gear lubes flow readily in low temperatures and provide outstanding protection in high temps. Four-bys enjoy both smooth shifting and tough, dependable protection in all conditions.

Clean running - Stable even in extreme heat, AMSOIL synthetic gear lubes resist oxidation and thermal breakdown, helping gears stay free of sludge and other deposits.

These state-of-the-art AMSOIL formulations feature an exclusive blend of high viscosity, shear stable synthetic base oils and an extra treatment of high-performance additives. AMSOIL Severe Gear Synthetic EP Lubricants maintain their viscosity for long-lasting protection against metal-to-metal contact. The proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring. AMSOIL Severe Gear lubricants prevent "thermal runaway" - a phenomenon caused by a lubricant's inability to control friction and increased heat under high-stress conditions. By preventing thermal runaway, AMSOIL Severe Gear Synthetic EP Lubricants inhibit rapid lubricant degradation and component damage. Equipment runs better and lasts longer with AMSOIL Severe Gear Synthetic EP Lubricants. Use in differentials, manual transmissions or other gear applications where one or more of the following standards are specified: API GL-5 & MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037) for 250,000 miles, Mack GO-J, Arvin/Meritor 0-76N, plus hypoid gear oil specifications from all foreign and domestic manufacturers such as GM, Ford and Daimler Chrysler. Can also be used in rear axles where API Service GL-4 lubricant is recommended. Performance AMSOIL SEVERE GEAR™ provides performance beyond that possible with conventional gear oil. These AMSOIL custom products offer superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life. Temperature Extremes AMSOIL SEVERE GEAR™ EP lubricants excel in hot and cold temperature extremes. By design, they resist breakdown from high heat, preventing acids and carbon/varnish formation. Their waxfree construction also improves cold flow properties, improving fuel economy and cold weather shifting. Applications AMSOIL SEVERE GEAR™ Synthetic EP Lubricants are excellent for severe applications, such as towing, hauling, steep hill driving, commercial use, plowing, racing, off-road use, rapid acceleration, frequent stop-and-go operation and high ambient temperatures. Higher horsepower, towing and hauling capabilities of modern vehicles make turbo diesel pick-ups, SUVs, vans and delivery/utility vehicles especially prone to severe service. Other severe duty vehicles include light, medium and heavy-duty trucks, busses, heavy equipment, 4X4s, tow trucks, race cars, tractors, and motorhomes.

Otherwise, drain at twice the OEM interval for conventional oil. Follow the OEM drain interval (miles or hours) for synthetic oil. Otherwise, drain at twice the OEM interval for conventional oil. For product service life in non-differential applications, consult owner's manual or the OEM for either normal or severe synthetic oil service intervals. Where service intervals are unavailable, drain at twice the interval for conventional oil. Gear oils should be changed more frequently when operating vehicles or equipment in dusty or dirty conditions unless the gear system is properly sealed and equipped with membrane type breathers. AMSOIL SEVERE GEAR™ (75W-90) replaces competitors' 75W-90 and 80W-90 viscosity grades. AMSOIL SEVERE GEAR™ is compatible with conventional gear oils, however mixing oils reduces the benefits and nullifies the extended service life recommendations. AMSOIL SEVERE GEAR™ is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive. Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check and service the gear oil frequently when water contamination is possible.

However, AMSOIL gear lubes are multi-functional and may be used in many different applications. This chart conveys the best AMSOIL recommendation based on product design and operating environment. First row product recommendations offer superior performance in the respective applications. Second row product recommendations offer excellent performance in the respective applications. The third row is exclusive to SAE 80W-90 viscosity. AMSOIL Severe Gear™ 75W-90 (SVG) and 75W-140 (SVO) synthetic gear lubes have a performance emphasis on the extreme pressure and high heat of today’s vehicle differentials. AMSOIL Long Life 75W-90 (FGR) and 80W-140 (FGO) synthetic gear lubes have a performance emphasis on 500,000 mile extended drain intervals associated with larger sumps and lower operating temperatures of over-the-road truck differentials. AMSOIL 75W-90 synthetic gear lubes will outperform conventional 80W-90 gear oils in all applications and may be used as a replacement.AMSOIL offers 80W-90 (AGL) synthetic gear lube for those customers requiring this specific viscosity grade. * Abbreviated Version
