AMSOIL Severe Gear Synthetic Extreme Pressure 75W-140 Lubricant

AMSOIL SEVERE GEAR™ Synthetic Extreme Pressure (EP) 75W-140 Lubricant
Formulated for the severe operating conditions of today's pick-up trucks, SUVs, heavy equipment and other hard working vehicles

AMSOIL Severe Gear Synthetic Extreme Pressure (EP) Lubricants are premium grade lubricants specifically engineered for maximum performance in severe duty applications. 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.

Product Code: SVO

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.

For product service life in differentials, consult your owner's manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.

	NORMAL	SEVERE
Cars, SUV, Light & Medium Duty Trucks	Drain at 100,000 miles of service or according to the owner's manual, whichever is longer	Drain at 50,000 miles of service or according to the owner's manual, whichever is longer
Heavy Duty Class 8 Truck, Commercial Equipment	Follow the OEM drain interval (miles or hours) for synthetic oil up to 250,000 miles. 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-140) replaces competitors' 75W-140, 80W-140 and 85W-140 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.

AMSOIL Synthetic Gear Oil Recommendations

AMSOIL has optimized gear lube performance for specific operating conditions. 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.
