PRODUCT LINE

Spirax HD oils are extreme-pressure (EP) automotive hypoid gear oils designed to exceed the latest performance standards for heavy duty, severe service.

APPLICATIONS

Spirax HD oils are designed for service in the drive-train gears of heavily loaded equipment and passenger vehicles. They are recommended for the lubrication of hypoid, spur, bevel, helical, spiral-bevel and worm gears in differentials, transmissions, final drives, transfer cases, and steering mechanisms.

Spirax HD 75W-90 and 80W-90 are our premium all-season, multigrade gear oils designed to exceed Original Equipment Manufacturers lubrication requirements under today’s increased temperature and loads. Spirax HD 85W-140 is recommended for high temperature heavy duty equipment and is typically used in off-highway applications.

PERFORMANCE BENEFITS

  • Superior Load Carrying Ability - The EP additives contained in all Spirax HD oils provide excellent, long lasting protection against scuffing and minimize wear, even in the toughest operating conditions.
  • Superior Thermal and Oxidation Stability - Spirax HD provides superior resistance to high temperature decomposition (breakdown). Even when operating conditions approach 150 °C, Spirax HD outperforms conventional API GL-5 lubricants. This improved thermal and oxidation stability helps ensure that deposits do not form around seals and helps maintain clean bearing surfaces to minimize wear.
  • All-Season Service – Depending on the ambient temperatures involved, Spirax HD 75W-90 and 80W-90 provide potential one grade, all-season operation. They can eliminate the need for seasonal changes and reduce the number of gear oils required.
  • Potential for Fuel Economy - Spirax HD multigrade and low temperature range features lessen frictional energy loss which improves fuel economy.
