Castrol Transmax Axle EPX 85W-140 is a multipurpose axle oil for use in differentials, final drives and other applications requiring a heavier extreme-pressure (EP) gear oil to API GL-5 specification. The product is positioned for commercial vehicle and heavy-duty axles operating under high-load or hot-ambient conditions where a thicker oil film is required than the more common SAE 80W-90 grade.
The SAE 85W-140 heavy multigrade hypoid gear oil viscosity is the heavier general-service viscosity for heavy commercial vehicles, towing vehicles and warm-climate axle operation.
Approvals and performance levels include API GL-5; and ZF TE-ML 05A.
Castrol Transmax Axle EPX 85W-140 is also available in a 208-litre drum (15DB2B) for workshop bulk supply.
The 20-litre pack format is suited to single-machine top-up and small workshop service. Store sealed in the original packaging, in a clean, dry area away from extremes of temperature, to preserve product performance over its shelf life.
Castrol Transmax Limited Slip Z 85W-90 is a mineral oil-based gear oil which is suitable for use in limited slip differentials in cars and commercial vehicles where API GL-5 oils with specific limited slip friction performance is required. It can also be used in conventional differentials. It is approved by ZF for use in their multi-disc wet brakes and self-locking differentials used in a range of commercial vehicle applications including axles in off-road and agricultural equipment.

A. Castrol Transmax Axle EPX 85W-140 is designed for commercial vehicle and heavy-duty axles operating under high-load or hot-ambient conditions where a thicker oil film is required than the more common SAE 80W-90 grade — including heavy commercial vehicles, towing vehicles and warm-climate axle operation.
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.
A. Castrol Transmax Axle EPX 85W-140 meets API GL-5.
A. Yes, Castrol Transmax Axle EPX 85W-140 carries ZF TE-ML 05A approval.
A. Both are Castrol Transmax Axle EPX mineral API GL-5 hypoid axle oils with the same EP additive system. EPX 80W-90 is the standard general-service viscosity for passenger car and light commercial vehicle axles. EPX 85W-140 (this product) is the heavier viscosity for heavy commercial vehicles, towing vehicles or hot-ambient axle operation.
A. Use EPX 85W-140 where the axle manufacturer specifies SAE 85W-140 or where the axle operates under high-load (heavy commercial vehicles, towing vehicles) or hot-ambient conditions that require a heavier oil film. For most passenger car and light commercial vehicle axles, the 80W-90 grade is the correct selection.
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.
