Shell Spirax S6 ATF ZM
Shell Spirax S6 ATF ZM is a fully synthetic heavy-duty automatic transmission fluid developed specifically for modern commercial vehicle transmissions. Designed in collaboration with ZF, the fluid is engineered to meet the demanding lubrication requirements of the latest generation ZF-Ecomat and ZF-Ecolife automatic transmissions. The advanced formulation uses high-quality synthetic base oils combined with exclusive additive technology to deliver exceptional durability, smooth transmission performance and extended service intervals even under severe operating conditions.
One of the key advantages of Shell Spirax S6 ATF ZM is its capability to support extended oil drain intervals. The lubricant has been specifically developed for ZF heavy-duty transmission systems and enables significantly longer service intervals compared with conventional transmission fluids. The advanced formulation allows transmissions to operate reliably for extended periods while maintaining consistent lubrication performance. This helps reduce maintenance downtime and overall operating costs for commercial vehicle fleets.
Shell Spirax S6 ATF ZM also provides excellent protection for transmission components operating under demanding conditions. The advanced additive system forms a durable lubricating film between gears, bearings and hydraulic components, helping to prevent wear and surface damage. This protection helps extend the service life of transmission components while ensuring reliable drivetrain performance in heavy-duty applications such as buses, trucks and other commercial vehicles.
Another important benefit of Shell Spirax S6 ATF ZM is its outstanding low-temperature fluidity. The combination of synthetic base oils and advanced additive technology ensures excellent oil flow at low temperatures, allowing rapid lubrication during cold starts. This helps protect transmission components from premature wear and ensures consistent hydraulic control and shifting performance even in cold operating environments.
Shell Spirax S6 ATF ZM also delivers smooth shifting performance and improved operational comfort. The stable friction characteristics of the fluid ensure precise clutch engagement and efficient power transfer within the transmission. This contributes to improved shift quality and overall drivetrain efficiency while helping maintain consistent transmission operation throughout the service interval.
The fluid is recommended for use in heavy-duty automatic transmissions including ZF-Ecomat and ZF-Ecolife transmissions used in buses, trucks and other commercial vehicles. It is also suitable for transmissions equipped with retarders. The product meets key industry approvals including ZF TE-ML 04D, 14E, 16N, 20F and 25F as well as MAN 339 Type Z13 for ZF-Ecolife transmissions and MAN 339 Type Z4 for ZF-Ecomat transmissions. Physical characteristics include a kinematic viscosity of approximately 61.8 mm²/s at 40°C and 10.2 mm²/s at 100°C with a viscosity index of approximately 153. The fluid has a density of approximately 843 kg/m³ at 15°C, a flash point of approximately 240°C and a pour point of approximately –51°C, supporting reliable lubrication performance across a wide range of operating conditions.
