Gulf Gear MZ 80W-90
Premium Performance Automotive Gearbox Oil
Gulf Gear MZ series are premium performance gear lubricants designed to provide effective lubrication in a wide range of automotive transmissions. These are formulated from high quality base stocks and proven performance extreme pressure additives to provide protection to gear components against wear and scoring. They offer protection against oxidation degradation and rust & corrosion. Gulf Gear MZ exceeds requirements of Daimler MB 235.5, MAN 341 Typ Z-2 and ZF TE-ML- 02B and 17A (SAE 80W and 80W-90) and 16A, 17A and 19A (SAE 80W-90, 85W-90 and 90) for gear oils.
Features & Benefits
- Excellent extreme pressure and antiwear properties protect against wear and scoring leading to lower maintenance costs, enhanced equipment durability and potential for long service life
- High oxidation stability minimizes deposit formation facilitating longer gear and bearing life
- Effective rust and corrosion protection reduces wear and extends component life
- Better low temperature fluidity (SAE 80W, 80W-90 and 85W-90) reduces wear at start-up and helps in smoother shifting at low ambient temperatures
- Good anti-foam properties ensure film strength for effective lubrication
- Excellent seal compatibility helps minimize leakages and reduce chances of contamination
Applications
- Heavy duty manual transmissions and axle drives where API GL-4 quality oils are specified
- On-road light and heavy duty trucks, buses, vans and passenger cars
- Off-highway equipment in construction, mining and agriculture
- Other applications involving spiral bevel gears operating under moderate to severe speeds and loads and axles with hypoid gears operating under mild to moderate speeds and loads
- Gulf Gear MZ 80W and 80W-90 are recommended for extended drain (compared to ZF TE-ML 02A) in ZF transmission where ZF TE-ML 02 A/B type of oils are recommended
- Not suitable for automatic transmissions
