Purpose and Specifications

Eurol 80W90 HPG GL5 1L is a tough mineral transmission oil built for hypoid gears, differentials, manual transmissions, and drive axles in cars, trucks, and buses. It meets API GL5 standards, shielding gears from wear, rust, and foam even under heavy shock loads and high heat.

This oil flows smoothly down to -25°C for reliable winter starts and holds strong up to 200°C+ operating temps, cutting shifting issues and boosting fuel efficiency. As a universal 'total drive line' formula, it simplifies stocking one oil for mixed fleets.

When to Use / Replace?

Use in any GL5 or GL4 gearbox calling for 80W90 viscosity, like rear differentials or manual transmissions. Perfect for heavy-duty hauling, towing, or off-road where gears take a beating.

• Replace every 40,000-60,000 km or 2-3 years under normal driving; halve that for towing or extreme loads.
• Drain and refill if shifting gets noisy or gritty after 100,000 km total service.
• Shelf life: 5 years sealed; store cool and dry.

FAQ

Q: Can I use this in my daily driver manual transmission?
A: Yes, if it specs GL5 or GL4 80W90. It protects synchronizers for smooth shifts in all seasons.

Q: Is it safe for limited-slip differentials?
A: Standard GL5 works for most open diffs; check manual for LSD-specific needs or grab Eurol's LSD version.

Q: How much for a typical gearbox change?
A: 1-2 liters for cars, up to 5L for trucks. Warm engine, drain old oil, refill to dipstick level.
