Gear failure can cost thousands in downtime! Select Synthetics in Thunder Bay, ON shares AMSOIL Severe Gear applications that prevent catastrophic breakdowns.

Transform your vehicle maintenance with synthetic gear lubricants that deliver on their promises. Call Select Synthetics in Thunder Bay, ON, at (807) 853-0807 to order, or explore AMSOIL's official website to learn about every severe gear formulation.

Your differential, transmission, and axle assemblies endure crushing loads, extreme temperatures, and constant stress that would destroy ordinary gear lubricants within months. Selecting the wrong viscosity or inferior protection can result in catastrophic failures that cost thousands in repairs and downtime. Understanding proper gear lube matching ensures maximum protection and significantly extends component life.

Professional operators and serious enthusiasts recognize that AMSOIL Severe Gear applications provide unmatched protection across the broadest range of operating conditions. This advanced synthetic formulation, from construction sites to racing circuits, delivers consistent performance when conventional gear oils fail completely.

Understanding Viscosity Requirements for Different Applications

Gear oil viscosity determines how effectively the lubricant flows at startup and maintains protective film strength under load. The SAE viscosity rating system helps match oil thickness to specific operating conditions, but understanding real-world applications proves more complex than following manufacturer recommendations.

75W-90

Provides excellent cold-weather flow characteristics while maintaining adequate protection for most passenger vehicle applications. This viscosity works exceptionally well in moderate-duty differentials, manual transmissions, and transfer cases operating in temperate climates.

75W-140

Deliver superior high-temperature protection for heavy-duty applications, including towing, racing, and commercial use. The higher viscosity index maintains film strength under extreme loads that would squeeze out thinner lubricants, preventing metal-to-metal contact.

AMSOIL Severe Gear Performance Advantages

AMSOIL Severe Gear outperforms conventional and competing synthetic gear lubricants through advanced additive technology and superior base oil selection. Independent testing demonstrates up to 3X better wear protection than conventional gear oils, with dramatically improved thermal stability.

The proprietary extreme-pressure additive package creates a sacrificial barrier that prevents gear tooth scuffing and scoring under shock loads. This protection becomes critical in AMSOIL Severe Gear applications involving sudden acceleration, heavy braking, or impact loading that destroys conventional lubricants.

Commercial and Industrial Applications

Construction equipment represents one of the most demanding environments for gear lubricants. Excavators, bulldozers, and heavy loaders operate in contaminated conditions with shock loading that rapidly destroys inferior lubricants. AMSOIL Severe Gear applications in these environments consistently outperform OEM-specified products.

Agricultural machinery faces similar challenges with seasonal heavy loading during planting and harvest operations. Tractors, combines, and implement drives benefit significantly from Severe Gear's superior load-carrying capacity and extended drain intervals that reduce maintenance during critical operating periods.

Fleet operations including delivery trucks, garbage haulers, and utility vehicles experience dramatic cost savings through reduced maintenance and extended component life. Many commercial operators report differential and transmission life improvements exceeding 200% after converting to AMSOIL Severe Gear.

Towing applications regularly stress gear assemblies beyond design limits. Heavy trailers, boat hauling, and RV towing create sustained high-load conditions where conventional gear oils fail. Severe Gear's superior film strength prevents the micro-welding and scoring that destroy gears under these conditions.

Racing and High-Performance Applications

Drag Racing

These applications demand instant protection from zero RPM launch to maximum acceleration. AMSOIL Severe Gear's film strength characteristics provide immediate protection that prevents gear tooth damage during violent launches that would destroy street gear oils instantly.

Circle Track Racing

This creates sustained high-load conditions with rapid temperature cycling that challenge even premium lubricants. AMSOIL Severe Gear applications in these environments demonstrate superior consistency throughout extended race events where conventional oils fade and fail.

Off-road Competition

It combines shock loading with contamination exposure and represents the ultimate gear lubricant test. Rock crawling, desert racing, and mud racing all benefit from Severe Gear's superior protection and extended drain capability.

Street Performance

Street performance enthusiasts building high-horsepower vehicles need confidence that their drivetrain can handle increased power levels. Severe Gear provides the safety margin for modified applications producing significantly more torque than original equipment specifications.
