The Quick Guide to top Three Best Gear Oils

While the primary application of gear oil is in transmiss ions for automobiles, these oils are made to be used pretty much anywhere a gearbox can be found. Among the various types of gear oils, the royal purple gear oil stands out for its exclusivity.

The best gear lubricants found:

1. Mobil 1 Synthetic Gear Lube LS

Thanks in part to synthetic base oils, Mobil 1 Synthetic Gear Lube LS is stable across a wide range of temperatures. It remains fluid to -50 degrees Celsius, yet it retains its viscosity even in hot-running, high-performance differentials and rear axles, including limited-slip differentials. Mobil 1’s additive package includes sulfur and phosphorus, but does not corrode yellow metals like brass bearing cages. It is suitable for all gear oil applications requiring an API GL-5 rating. 

Pros:

• Extended drain intervals
• Excellent cold fluidity
• Mild EP additives
• Superior shear stability

2. Royal Purple Max Gear

Royal Purple enjoys a reputation for high performance and long drain intervals, and its Max Gear lubricant lives up to the hype. Max Gear is fully synthetic, so it flows in cold temps and retains its viscosity in hot-running, heavy-duty hypoid differentials and other GL-5 applications. Unlike many other gear lubricants, Max Gear is also suitable for GL-4 applications like manual transmissions and front-wheel-drive transaxles. Royal Purple manages to satisfy both ratings with its proprietary Synerlec additive package, which does not harm soft metals in synchronizers.

Pros:

• Keeps gears cooler
• Maximizes use of available horsepower
• Excels in heavy-duty applications
• Suitable for light-duty manual transmissions
• Meets both GL-4 and GL-5 ratings

3. Red Line MT-90

Manual transmissions require a gear-oil with reduced slipperiness to improve synchronizer function. Red Line MT-90 is an API GL-4 synthetic gear lube that protects synchronizers and gears from wear. Its additive package also enables easier shifting in cold temperatures. Like all GL-4 lubricants, MT-90 lacks the sulfur additives that can corrode and damage brass and copper manual transmission components. MT-90 is suitable for GM, Ford, VW, Audi and many other applications.

Pros:

• Fully synthetic
• Ester base oils
• Sulfur-free
• Not too slick for synchronizers
• Slick enough for smooth shifts
