PURUS® Premium VI-S™ Heavy Duty SAE 75W-80 Transmission Fluid is a synthetic SAE 75W-80 manual or automated manual transmission lubricant formulated to provide outstanding protection for 500,000 mile drain intervals in demanding service in light to heavy-duty
commercial vehicles. PURUS® Premium VI-S™ Heavy Duty SAE 75W-80 Transmission Fluid provides excellent oxidation and thermal stability, wear and extreme pressure protection, as well as corrosion inhibition to fully protect metal parts and seals across a wide temperature range in severe-duty service. The lower viscosity on the 75W-80 will provide improved fuel economy relative to the more viscous 75W-90 and 75W-85 viscosity grades.
