Castrol Transmax Axle Long Life 75W-90, formulated with Smooth Drive Technology, is a fully synthetic rear axle fluid. It provides protection especially when driving under stop-start or extreme conditions such as towing, enabling smoother gear engagement and supporting axle component life across extended drain intervals.
The SAE 75W-90 multigrade hypoid gear oil viscosity is positioned for passenger car, light commercial vehicle and 4x4 rear axles requiring an API GL-5 hypoid-gear lubricant with extended drain capability. The full synthetic chemistry supports operation across wide ambient temperatures and reduces axle drag for fuel-efficiency benefits.
Approvals and performance levels are positioned within the API GL-5 hypoid axle gear oil class — verify the specific OEM-approval set against the current product label.
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 Axle Long Life 75W-90, formulated with Smooth Drive TechnologyTM, is a full synthetic rear axle fluid. It provides superior protection, especially when driving under stop-start or extreme conditions e.g. towing. This enables smoother axle operation and noise reduction, resulting in a more comfortable drive throughout the lifetime of the vehicle. Specially designed and approved by BMW for use in all BMW final drives fitted with conventional (non limited slip) differentials. It is Castrol's prime recommendation for final drives in heavy commercial vehicles, and is approved by MAN, Scania and ZF

A. API GL-4 is the performance category for manual transmission gear oils.

A. Yes, Castrol Transmax Axle Long Life 75W-90 is positioned for stop-start or extreme conditions including towing, with the Smooth Drive Technology supporting axle component life under high-load conditions.
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. 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.
