Swepco SAE 80W-90 Gear Lube 1 Gallon — GL-5, EP Anti-Wear Formula for Differentials & Gearboxes

Swepco SWEPCO201 SAE 80W-90 is a multi-purpose extreme-pressure gear lubricant designed to protect gears, differentials, PTOs and manual transmissions under heavy load and high shock conditions.

Engineered from high-viscosity-index paraffinic base oils and advanced additives, SWEPCO201 combines adhesive/cohesive chemistry with LUBIUM anti-wear technology to reduce friction, resist shock loading and extend component life. The formulation targets long drain intervals, improved thermal stability, and resistance to oxidation, rust and corrosion—making it suitable for industrial gearboxes, final drives, manual transmissions and power take-off units where GL-5 performance is required.

What equipment is SWEPCO201 best suited for?

SWEPCO201 is formulated to perform across a broad range of drivetrain and industrial gear applications that demand SAE 80W-90 viscosity and GL-5 protection. It meets API GL-5 and MT-1 performance levels and exceeds MIL-PRF-2105E in many respects, so it fits many heavy-duty and off-highway uses.

• Manual transmissions and drive axles needing 80W-90 viscosity
• Final drives and differentials subject to shock loading
• Power take-off units and industrial gearboxes
• Limited-slip systems where controlled slip additives are required

How does this gear lube protect against wear and shock?

The blend includes extreme-pressure (EP) and anti-wear additives plus Swepco’s LUBIUM chemistry to form a durable lubricating film that resists metal-to-metal contact. Adhesive and cohesive properties promote climbing action on gear teeth, maintaining lubrication even under boundary conditions.

• EP additives cushion impact during shock loading
• Anti-wear chemistry reduces pitting and scuffing
• Adhesive/cohesive action helps retain film on vertical or inclined surfaces
• Reduced operating temperatures lower stress on bearings and seals

What contamination and longevity benefits can users expect?

SWEPCO201 includes antioxidant, rust and corrosion inhibitors plus anti-foam and anti-catalyst agents to help keep systems clean and stable over time. The formulation supports longer drain intervals and less frequent oil changes, which reduces waste oil and maintenance labor.

• Oxidation resistance helps maintain viscosity and prevents varnish
• Rust and corrosion inhibitors protect internal metal surfaces
• Anti-foam additives preserve film integrity at high shear
• Longer service life lowers downtime and disposal costs

Are there special handling or compatibility considerations?

SWEPCO201 is compatible with many elastomers and metals found in gear and transmission systems, but users should confirm compatibility with seals and previous lubricants before mixing. Follow OEM recommendations for viscosity grade and service classification to ensure proper use and performance.

• Check manufacturer specifications for recommended SAE 80W-90 GL-5 lubes
• Avoid mixing with unknown additives that could alter limited-slip behavior
• Store in a cool, dry place and keep container sealed to prevent contamination
• Consult technical data sheet for full compatibility and safety guidelines

Who is this for: SWEPCO201 SAE 80W-90 is aimed at fleet managers, equipment owners, agricultural and construction operators, and maintenance technicians who need a robust, multi-purpose gear oil that reduces wear and extends service intervals. If you operate heavy-duty differentials, manual transmissions, PTO-driven implements or industrial gearboxes that experience heavy loads and shock events, this formulation delivers the lubricity, film strength and corrosion protection required to keep equipment running longer with less downtime.
