Q 1. What transmissions and axles is Castrol Transmax Universal LL 75W-90 designed for?

A. Castrol Transmax Universal LL 75W-90 is a fully synthetic multipurpose manual transmission and final drive lubricant for synchronised manual transmissions and final drives across passenger car and commercial vehicle applications.

Q 2. What is an API/ACEA classification?

A. API and ACEA are the universal lubricant performance standards every reputable oil meets. They are your baseline check — match the code your handbook specifies (e.g., API CI-4 or ACEA E7 for heavy-duty diesel) and the oil is technically suitable for your machine. Every oil on our site lists its API and ACEA classifications.

Q 3. What performance classifications does Castrol Transmax Universal LL 75W-90 meet?

A. Castrol Transmax Universal LL 75W-90 meets API GL-4 and GL-5; and SAE J2360.

Q 4. What is an OEM Specification?

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.

Q 5. What is an OEM Approval?

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.

Q 6. What OEM manufacturer approvals does Castrol Transmax Universal LL 75W-90 carry?

A. Castrol Transmax Universal LL 75W-90 carries MAN M341 Z; MAN M342 S; and ZF TE-ML 02B.

Q 7. Is Castrol Transmax Universal LL 75W-90 a synthetic fluid?

A. Yes, Castrol Transmax Universal LL 75W-90 is a fully synthetic multipurpose manual transmission and final drive lubricant.

Q 8. Can Castrol Transmax Universal LL 75W-90 be used in both manual transmissions and rear axles?

A. Yes, Castrol Transmax Universal LL 75W-90 is positioned as a universal fluid — meeting both API GL-4 (manual transmission) and API GL-5 (hypoid axle) requirements. It may be used in synchronised manual transmissions and final drives. Always check the equipment manufacturer's specification before substituting.

Q 9. What is SAE J2360?

A. SAE J2360 is a US military-derived heavy-duty automotive manual transmission and rear axle gear oil specification that consolidates the requirements of multiple US military specifications. SAE J2360 approval indicates the product has passed an extended series of laboratory and field tests beyond the basic API GL-5 requirements.
