Spirax gear oils join Shell lubricant line

Shell Lubricants has expanded its family of heavy-duty lubricants by adding the Spirax EW Extended Warranty SAE 75W-90 and 80W-140 gear oils. The new mineral-based gear oils meet the extended-warranty requirements of heavy-duty axles manufactured by Dana, ArvinMeritor, and Mack.

To gain the approvals, Shell subjected its lubricants to more than 50 million miles of field-testing under varied conditions and temperatures. Shell also conducted laboratory testing to qualify the Spirax EW lubricants under United States military specification MIL-PRF-2105E.

As a result, Spirax EW gear oils are now approved for 500,000-mile extended drain intervals for both Dana axles and ArvinMeritor axles equipped with pump and filter systems. The lubricants also are approved for use in Mack axles at 250,000-mile drains. The approvals allow fleets and independent truck operators to use Spirax EW gear oils for both service-fill and factory-fill at the same change interval specified for approved synthetic fluids, and still qualify for Dana and ArvinMeritor 750,000-mile extended warranty coverage.

Shell Spirax EW gear oils will be available in bulk, drums, kegs, pails, and quarts. Additional information is available at
