Pennzoil Axle 80-W90 (GL-5) — 1 Quart
Pennzoil 80-W90 (GL-5) is formulated to maintain fluidity at low temperatures while resisting thinning at high temperatures. The formulation helps prevent rust and provides stable lubrication across a wide temperature range, supporting longevity in axles, differentials, and manual transaxles.
Buying Guide
Key purchase considerations when selecting 80W-90 gear oil include viscosity stability, extreme-pressure performance, anti-wear protection, and heat management. Consider the following perspectives:
- Application and equipment type: Heavy-duty trucks, off-road gear, or manual transmissions may require different EP additives and basestocks.
- Temperature range: Choose formulations designed for your climate and operating conditions, especially if equipment runs hot or in freezing environments.
- Lubricant packaging: Gallon vs. quart containers affect spacing, logistics, and refills for preventive maintenance schedules.
- Compatibility: Check OEM specifications (GL-5, LS compatibility, or limited-slip formulations) to ensure proper fit with gears and differentials.
- Protection profile: Look for products with strong anti-wear, corrosion resistance, and shear stability to minimize wear and downtime.
