TRUEGARD HD 80W/90 55 GALLON PAIL DRUM

80W-90 is a multi-grade gear lubricant where '80W' describes its low-temperature flow performance and '90' describes its viscosity at operating temperature. This grade is a standard specification for manual transmissions, differentials, and drive axles - always verify your equipment manufacturer's viscosity requirement before use.

HD' stands for Heavy Duty, indicating the oil is formulated to handle demanding gear and drivetrain applications that involve high loads and sustained mechanical stress, as opposed to lighter-duty gear lubricant formulations.

The 'W' stands for Winter and refers to the oil's cold-temperature pumpability rating. A multi-grade 80W-90 performs across a wider temperature range than a single-weight 90-grade oil, making it more versatile in environments that experience significant temperature variation.

A 55-gallon drum is a bulk purchase format best suited for fleet maintenance operations, heavy equipment service facilities, or industrial sites that consume gear oil in large quantities on a regular basis, offering a lower cost-per-gallon compared to smaller containers.
