Multi-Purpose Gear Oil
Properties
Astron MZ 80W-90 GL 4 is made from carefully chosen base oils and additives. The EP additives contained in the gear oil form a load-bearing lubricant film between the tooth flanks when the gears intermesh. This layer reduces abrasion on the tooth flanks during movement of the gears under high mechanical load. The gear oil is extremely ageing resistant, even under high thermal load. The good low-temperature viscosity is achieved through the high degree of refining of the base oil and the added flow improver. The gear oil contains highly effective active agents that suppress foaming and protect the lubricated machine parts against damage from corrosion.
Astron MZ 80W-90 GL 4 does not cause damage to conventional sealing materials.
Use instructions
Astron MZ 80W-90 GL 4 is recommended for use in manual transmissions, steering gears and axle drives in passenger and commercial vehicles (not suitable for hypoid gears).
