Pennzoil Platinum Axle 75W-140
Pennzoil Platinum® Axle 75W-140 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 lubrication during very low temperature axle and transmission startup, and also assists in maintaining a thick, protective oil film during extremely hot operating conditions1.
Pennzoil Platinum® Axle 75W-140 is formulated with performance additives necessary for outstanding protection of gears and bearings. It contains extreme pressure agents which protect against shock loading and wear, and also protects against corrosion with special rust inhibitors2. Oxidation inhibitors are included to further enhance this synthetic oil's inherent oxidation stability, resulting in a lubricant with exceptionally long service life and excellent resistance to deposit and sludge formation during high temperature operation.
SAE 75W-140, API GL-5 is typically used as service fill rear axle oil for many passenger cars and trucks with high loads or very high horsepower. The higher viscosity base stocks help protect gears by maintaining the oil film in addition to the extreme pressure agents used to reduce metal to metal wear. Many ¾- and 1-ton trucks used in trailer towing will benefit from this product.
SUVs and Trucks in particular may be equipped with limited slip differentials. Pennzoil Platinum® Axle 75W-140 contains sufficient limited slip friction modifier for many applications. Newer applications however may require addition of additional limited slip friction modifier. Pennzoil Platinum® Axle 75W-140 is fully compatible with additional friction modifiers.
1 SAE J306 viscosity limits for SAE 75W-1400 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-140 are identical to SAE 80W-140, SAE 85W-140 and SAE 140 providing for similar oil flow and film thickness at elevated temperature (100°C).
2 Read across from SAE 75W-90, SAE L-37 and L-42 test data demonstrate passing and excellent (10 rating) wear and shock loading performance of additive system.
