Purpose and Specifications

ORLEN HIPOL GL-4 80W-90 5L is a tough mineral transmission oil designed for manual gearboxes, differentials, and axles in cars, trucks, and heavy machinery. It delivers excellent lubrication to cut wear, fights rust inside gears, resists breakdown from heat, and handles heavy loads without thinning out.

This oil flows smoothly at cold starts down to -30°C, keeping shifts easy in winter, and stays stable up to 235°C flash point for hot summer hauls or tough towing. The 80W-90 grade means it pumps easily when cold yet protects thick under high-speed or high-torque stress. Perfect for 5-liter refills on vehicles needing API GL-4 spec oil.

When to Use / Replace?

• Use in manual transmissions, rear differentials, and axles of cars, trucks, and construction equipment running high-speed/low-torque or low-speed/high-torque conditions.
• Replace every 40,000-60,000 km or 24-36 months under normal driving; sooner at 20,000-40,000 km for heavy towing, off-road, or extreme temps.
• Check fluid level and color every 10,000 km; dark or burnt smell means change it to avoid gear damage.

Shelf life is 3-5 years unopened in cool, dry storage.
