Royal Purple Max Gear 75w140 Fully Synthetic Performance Gearbox Oil
Royal Purple Max Gear 75w140 Fully Synthetic Gearbox Oil is an ultra-tough, high performance automotive transmission gear oil designed to provide maximum protection to heavily loaded gears while maximizing power throughout the drivetrain.
Royal Purple Max Gear makes transmission internals run smoother, quieter, cooler and longer without overhauls.
Provides smooth operation and high levels of protection at very high temperatures as well as excellent resistance against shear and ageing.
Max Gear outperforms other GL-5 specified gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.
For use in differentials, rear axles, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. Max gear is also suitable for use in limited slip/positrac applications.
What is Synslide Additive Technology?
Synslide additive technology is Royal Purple’s tough, extreme pressure (EP) lubricating film that provides maximum protection under boundary lubrication conditions typically caused by heavily loaded, slow speed and/or shock load conditions. This tenacious, slippery film significantly improves lubrication and reduces wear by increasing the oil film thickness and toughness, which helps to prevent metal-to-metal contact in gears and bearings.
It is Royal Purple’s advanced Synslide additive technology that gives Royal Purple’s extreme pressure lubricants their amazing performance advantages, therefor making it a superior lubricant. Synslide additive technology truly is beyond synthetic.
Synslide additive technology displaces water from metal surfaces and excels in protecting equipment in wet environments. It also fortifies the oil against the detrimental effects of heat, which causes oil to oxidize. It is noncorrosive to gears and bearings, including case-hardened gears that are easily pitted by conventional sulfur-phosphorus extreme pressure oils.
Royal Purple Max Gear 75w140 certifications/licensing:
- API: GL-4 & GL-5
Royal Purple Max Gear 75w140 Performance Advantages:
- SUPERIOR WEAR PROTECTION - Exceeds Eaton’s stringent GL-5/MIL-L-2105D Gear Oil Specifications and also is safe for GL-4 applications as well as bronze synchro gears
- MAXIMISES HORSEPOWER - Reduces operating temperatures, improves & smooths gear shifting and extends gear & bearing life
- LOWER COEFFICIENT OF FRICTION - Saves energy, reduces temperatures and maximizes power throughout (OEM or aftermarket limited slip additives are not required)
- MEETS WARRANTY REQUIREMENTS - Meets or exceeds OEM warranty requirements for GL-5 automotive rear axle hypoid gear lubrication
- HIGH TEMPERATURE PERFORMANCE - Eliminates harmful deposits and extends oil drain intervals
- LOW TEMPERATURE FLUIDITY - Meets operating temperatures for transmissions operating in cold climates
- RAPIDLY SEPERATES FROM WATER - Completely separates from water, preventing an oil water emulsion
- ENVIROMENTALLY RESPONIBLE - Components are TSCA listed and meet EPA, RCRA and OSHA requirements. Max gear extends oil drain intervals, eliminates premature oil changes, decreases the amount of oil purchased and disposed of and conserves energy
Royal Purple Max Gear 75w140 is highly recommended for vehicles requiring any of these transmission fluids:
- Manual transmissions/transaxles specifying 75w140, Transaxle GL-4 or GL-5
- BMW/MINI - Castrol SAF-XJ (limited-slip)
- CHRYSLER/JEEP - 04874469
- NISSAN - Castrol SAF-XJ
