Frequently asked questions

Find answers to common questions about our products and services

  • 85W/90 is a multi-grade gear oil designation where '85W' describes the oil's cold-temperature flow characteristics and '90' describes its viscosity at normal operating temperature. Always consult your equipment or vehicle manufacturer's service manual to confirm that 85W/90 is the specified viscosity grade for your axles, differentials, or gearboxes before filling.

  • The 'HD' designation indicates the lubricant is formulated for heavy-duty gear applications, meaning it is intended to handle the higher loads and stresses found in demanding equipment environments. Check your equipment's service documentation to verify that an HD-grade 85W/90 gear lubricant meets the required service category for your application.

  • A 55-gallon drum is a bulk format best suited for fleets, service shops, or industrial operations with significant and recurring gear oil consumption. You will need a compatible drum pump or dispensing equipment, as well as adequate storage space appropriate for bulk lubricants, before ordering in this quantity.

Key Features

  • Multi-grade 85W/90 viscosity designation balances cold-temperature flow characteristics (85W) with viscosity at normal operating temperature (90), making it applicable to gear lubrication needs.

  • Heavy-duty (HD) designation indicates the lubricant is formulated to handle higher loads and stresses found in demanding equipment environments.

  • Bulk 55-gallon drum format is best suited for fleets, service shops, and industrial operations with significant and recurring gear oil consumption.

  • Dispensing from this bulk drum format requires a compatible drum pump or dispensing equipment, as well as adequate storage space appropriate for bulk lubricants.

  • Intended for use in gear applications such as axles, differentials, and gearboxes - always consult your equipment manufacturer's service documentation to confirm the correct viscosity grade and service category before filling.
