A. ZF allows a maximum oil-change interval of up to 540,000 km on certain commercial transmissions when an approved long-drain fluid such as Castrol Transmax Manual Z Long Life 75W-80 is used. The actual drain interval should be verified against the transmission manufacturer's service schedule and operating conditions.
A. An OEM Specification is the lubricant requirement set by a vehicle or equipment manufacturer (e.g., MB 228.3, VW 504.00). When an oil lists the code, the oil manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a lubricant engineered for your machine.
A. An OEM Approval means the oil has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 228.3). An Approval confirms the oil is recognised by the equipment manufacturer for service use in their machines.
