Protect your vehicle's drivetrain with Penrite Gear Oil 80W-90 Mineral, a premium mineral automotive gear oil designed to provide reliable lubrication, extreme pressure protection and dependable performance under demanding operating conditions. Formulated with modern extreme pressure additives and friction modifiers, it helps protect critical drivetrain components against wear, scoring and surface damage while supporting smooth and reliable operation under heavy loads.

Over time, drivetrain components can experience increased friction, wear and deterioration caused by heavy loads, shock loading, high operating temperatures and demanding driving conditions. These factors can contribute to gear noise, reduced efficiency and premature component wear. Penrite Gear Oil 80W-90 is formulated to provide strong load-carrying protection, excellent thermal stability and resistance to abrasive wear. Its anti-shudder additive technology and integrated limited slip additive help support smooth operation in compatible limited slip differentials without requiring an additional limited slip additive.

Designed for hypoid and limited slip differentials, manual gearboxes, transfer cases and transaxles, Penrite Gear Oil 80W-90 is suitable for compatible passenger cars, 4WDs, light commercial vehicles, trucks, construction equipment, earthmoving machinery and agricultural equipment where SAE 80W-90 gear oil is specified. It can also be used in compatible motorcycle final drives and four-wheeler front differentials where the recommended oil grade matches. Always confirm the required viscosity and performance specifications in the vehicle or equipment manufacturer's handbook before use.

Note: Always confirm the required gear oil viscosity and performance specification before use. Some manual gearboxes require a different lubricant, including products specifically formulated for synchronised transmissions. Check the manufacturer's recommendations to ensure compatibility.

Directions

• Check the vehicle or equipment manufacturer's handbook to confirm the correct gear oil viscosity and required performance specifications.
• Ensure the vehicle or equipment is parked safely on a level surface and follow the manufacturer's servicing precautions.
• Locate the appropriate gearbox, differential or transfer case filler and drain plugs according to the manufacturer's instructions.
• Drain the existing lubricant into a suitable collection container and inspect it for excessive contamination or metal particles that may indicate component wear.
• Refit the drain plug according to the manufacturer's recommended procedure and torque specifications.
• Fill the designated component with Penrite Gear Oil 80W-90 until the manufacturer's specified oil level is reached.
• Refit the filler plug securely and inspect for leaks around seals, housings and drain plugs.
• Follow the manufacturer's recommended oil change intervals, taking into account heavy loads, towing, off-road driving and other severe operating conditions.
• When changing lubricant types, check compatibility with the existing oil and ensure the new lubricant meets the required specification.
• Dispose of used gear oil responsibly through an appropriate recycling or waste collection facility.
