Pennzoil Platinum Gear 75W-90
Primarily for passenger cars and light trucks, Pennzoil Platinum® Gear 75W-90 combines a premium performance gear oil additive package with a high quality synthetic base stock. The result is a gear oil that helps provide excellent low temperature fluidity for safe lubrication during very low temperature transmission or gearbox startup, and also aids in maintaining a thick protective oil film during extremely hot operating conditions1. Fluid flow at cold temperatures is important to shift characteristics and lubrication of gear oils helping prevent wear and easing driving effort.
Pennzoil Platinum® Gear 75W-90 is formulated with the performance additives necessary for outstanding protection of gears and bearings. It contains extreme pressure agents which help protect against shock loading and wear. Foam inhibitors assist in protecting against oil aeration, and special rust inhibitors aid in protection against corrosion.
1 SAE J306 viscosity limits for SAE 75W-90 for low temperature viscosity allows a maximum temperature of -40° C for 150,000 cP viscosity with a typical of 90,000 to 120,000 cP for this product. The same viscosity maximum goes to -26° C for SAE 80W and -12° C for SAE 85W. 150,000 cP viscosity is associated with sufficient flow to prevent channeling of gear through oil. High temperature limits for SAE 75W-90 are identical to SAE 80W-90 and SAE 90 providing for similar oil flow and film thickness at elevated temperature (100°C).
