описание:
Geartex EP-C are high performance automotive gear lubricants suitable for use in applications requiring API GL- 5 performance. Formulated with mineral base stocks and highly effective additives these lubricants are available in viscosity grades SAE 80W-90 and 85W-140.
Customer benefits
• Reliable shear stability contributes to consistent viscosity and system protection throughout fluid service life
• Low temperature fluidity performance helps ensure rapid lubrication and system wear protection during cold start-up
• High performance EP protection promotes resistance to component scuffing and wear
• Robust oxidation stability helps protect against in-service oil thickening, and aids system cleanliness
• Compatible with a wide range of elastomers, assisting in fluid loss prevention though leakage
• Helps prevent components rusting and any resulting system damage
• Foam suppression optimises lubrication performance
Applications
• Geartex EP-C is designed for use in automotive hypoid drive axles, steering systems, non-synchronized transmissions and transaxles which require a fluid with API GL-5 performance
• The friction characteristics of Geartex EP-C make it unsuitable for use in synchronized manual transmissions and transaxles, and it should not be used in these applications unless a GL-5 fluid is specifically recommended
• Operating temperatures of above +100°C will lead to a significant reduction in the fluid service life. Peak operating temperatures should not exceed +120°C
• Note that Daimler axle oil specifications include a minimum viscosity requirement that is not met by Geartex EP-C 80W-90. Although Geartex EP-C 80W-90 is suitable for use in MB 235.0 applications, use Geartex EP-B 85W-90 if an approved product is required
