Castrol TRANSMAX Axle Long Life 75W-90 Fully Synthetic Rear Axle Fluid

Castrol TRANSMAX Axle Long Life 75W-90, formulated with Smooth Drive Technology™, 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.

Castrol TRANSMAX with Smooth Drive Technology™ has active control molecules that automatically adjust their friction level under changing pressures and speed, delivering a smoother drive for longer and enhanced protection. That’s why, 2 out of every 3 major vehicle manufacturers choose Castrol transmission fluids as part of their factory fill.

This product replaces Castrol Syntrax Longlife 75W-90.

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.
