TRUEGARD HD 80W/90 5 GALLON PAIL

80W/90 is an SAE multi-grade gear oil viscosity designation, where '80W' indicates the cold-flow performance (winter) and '90' indicates the high-temperature viscosity. This grade is commonly used in conventional differentials, manual transmissions, and transfer cases that specify an SAE 80W-90 lubricant - always verify your equipment manufacturer's recommendation before use.

The 'HD' designation indicates this is a heavy-duty formulated gear oil, designed to handle the higher loads and stress typical of commercial, agricultural, or fleet equipment rather than lighter-duty passenger-car applications.

While mixing gear oils of the same viscosity grade from different brands is generally not recommended, as additive packages can be incompatible, the product data does not specify mixing instructions. When switching products, it is best practice to fully drain and clean the system before filling with a new lubricant.

Gear oil in an opened pail should be stored in a cool, dry location away from direct sunlight, heat sources, and moisture. Keep the lid tightly sealed to prevent contamination and water ingress, which can degrade the lubricant's performance.

A 5-gallon pail is a cost-effective choice for fleet operators, shops, or equipment managers who perform regular differential or transmission services on multiple units, reducing per-unit cost and the number of containers to manage.
