Synthetic Gear Oils
Pennzoil® Synthetic Gear Oils are available in SAE 75W-90 viscosity grades of either API GL-4 or API GL-5 service classifications. Specially formulated with synthetic base stocks to meet the requirements that today’s cars, minivans, SUVs and light-duty trucks encounter in normal and severe driving conditions.
The synthetic base stocks used in Pennzoil® Synthetic gear lubricants provide better protection than low- and high-temperature conventional mineral-oil base stocks. They offer protection over a wide temperature range. The API GL-5 product is specially suitable for use in limited-slip differentials.
Pennzoil® Synthetic 75W-140 GL-5 Gear Oils
Pennzoil® Synthetic 75W-140 GL-5 Gear Lubricant combines a premium performance gear oil additive package with a high quality synthetic base stock. The result is a gear oil that provides excellent fluidity for safe lubrication of gears and axles during very low temperatures and also maintains a thick protective oil film during extremely hot operating conditions.
Pennzoil® Synthetic 75W-140 GL-5 is formulated with all the performance additives necessary for outstanding protection of gears and bearings. It contains extreme pressure agents that protect against shock loading and wear. Foam inhibitors protect against oil aeration, which can rupture the lubricant film and cause wear due to lack of lubrication. Special rust inhibitors are incorporated into Pennzoil® Synthetic 75W-140 GL-5 to protect against corrosion that can result from condensation. 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 formation during high-temperature operation.
Pennzoil® Synthetic 75W-140 GL-5 meets all the requirements of API Service Classification GL-5.
PENNZOIL SYNTHETIC GEAR OILS:
- Contain special extreme pressure and anti-wear additives, minimizing wear that can occur with high or shock loads
- Provide protection over a wide temperature range
- Protect against corrosion
- Provide outstanding thermal stability
- Reduce or eliminate chatter in limited-slip differentials
Pennzoil® Synthetic 75W-140 GL-5 Gear Lubricant is designed primarily for the lubrication of differentials and manual transmissions requiring an API GL-5 gear lubricant. It can be used in limited-slip and conventional differentials found in passenger cars, light trucks, sport utility vehicles and vans. It continues to flow at very low temperatures, providing especially good protection for gears and bearings in extreme cold weather. It also provides excellent service in torrid climates by not thinning at high temperatures, thereby maintaining a full film of protective lubricant on gear teeth. In hot-running gear boxes, it allows longer service due to the excellent stability of the synthetic base stocks used in the product. Pennzoil® Synthetic 75W-140 GL-5 is specially formulated for today’s stringent demands of everyday stop-and-go driving and towing applications.
Pennzoil® Synthetic 75W-140 GL-5 is suitable for use in both limited slip and conventional differentials. It may be used for makeup or complete refill of limited-slip differentials, including rebuilt units.
Passenger car or truck manual transmissions experiencing difficult shifting during cold weather while using conventional mineral-based GL-5 oils, will typically find easier shifting characteristics when using Pennzoil® Synthetic 75W-140 GL-5.
