Original ZF lubricant from ATS
ZF EcoFluid XL — efficient axle protection for modern bus and truck fleets
ZF EcoFluid XL is built for ZF bus and truck axles where protection and efficiency have to work together. Its SAE 75W-85 formulation combines temperature resistance, gear and bearing protection, and low-friction performance to help the axle run efficiently without giving up durability under fleet operating conditions.

Axles A series, wheel heads RL series, Low-floor portal axles AV series, Low-floor portal axles AV 133 with efficiency package, A series, RL series
Extended efficiency axle fluid registered under ZF approval number ZF003441, optimized specifically to decrease energy loss and support extended maintenance intervals on low-floor portal axles.
Why Choose Original ZF EcoFluid XL SAE 75W-85
ZF EcoFluid XL SAE 75W-85 brings ZF axle protection into a lower-viscosity profile designed to reduce drag without treating protection as an afterthought.
- The value is controlled efficiency: less internal resistance while maintaining the gear and bearing protection expected in ZF axle applications.
- ZF approval means the oil is matched to the lubricant class and application, not chosen only by SAE viscosity or a generic gear-oil label.
- For operators, the business case is clear: better service confidence, lower wear risk and less chance of costly axle-related downtime.

FAQ
Why choose original ZF EcoFluid XL SAE 75W-85 for an axle?
Axles work under high contact pressure. The oil must protect gears and bearings while matching the exact ZF lubricant class.
Is SAE viscosity enough to choose the right oil?
No. SAE viscosity does not replace TE-ML approval. The exact axle, operating conditions and lubricant class must match.
What should be checked during axle service?
Oil level, drain interval, breather condition, seals and the correct TE-ML class should be checked. A blocked breather or wrong oil can shorten the benefit of a good service.
What to Send for Fast Compatibility Check
- Photo of the ZF axle / drive nameplate or exact unit model.
- Vehicle or machine model and the exact application family.
- Mileage or operating hours, ambient conditions and duty profile.
- Previous oil type and recent service history if known.
