Mobil Delvac 1 ATF
Mobil Delvac 1 ATF is an advanced fully synthetic automatic transmission fluid engineered to meet the demanding requirements of modern heavy-duty transmissions. Developed with high-performance synthetic base oils and a carefully balanced additive system, it is specifically approved against Allison TES-295 and designed to deliver exceptional performance in commercial vehicles operating under severe conditions. The formulation ensures reliable operation in trucks, buses, vans and other heavy-duty equipment requiring high-performance transmission fluids.
One of the key advantages of Mobil Delvac 1 ATF is its outstanding thermal and oxidation stability. Heavy-duty transmissions often operate under extreme temperatures, which can accelerate fluid degradation. Mobil Delvac 1 ATF resists breakdown under high thermal stress, helping maintain fluid integrity and keep transmission components clean. This contributes to extended fluid life and improved transmission durability.
Mobil Delvac 1 ATF also provides exceptional frictional stability and smooth shifting performance. The advanced formulation maintains consistent frictional properties over time, ensuring reliable gear engagement and efficient power transfer. This helps improve transmission efficiency, enhance driving comfort and support fuel economy in commercial vehicle operations.
Another important benefit of Mobil Delvac 1 ATF is its excellent wear protection. The fluid forms a strong lubricating film between gears, bearings and clutch components, helping reduce wear and extend the life of transmission components. Its high film strength ensures reliable protection even under heavy loads and severe operating conditions.
Mobil Delvac 1 ATF also offers excellent low-temperature performance. The fluid remains highly fluid at sub-zero temperatures, providing rapid circulation and prompt lubrication during cold starts, even down to approximately −54°C. This helps minimise start-up wear and ensures consistent transmission performance in cold climates.
Mobil Delvac 1 ATF also demonstrates exceptional shear stability, maintaining its viscosity even under severe operating conditions. This ensures consistent lubrication performance throughout extended drain intervals. In addition, the fluid is compatible with conventional mineral ATF fluids, providing flexibility during top-up situations and helping maintain seal integrity.
Mobil Delvac 1 ATF is recommended for use in modern high-performance trucks, buses, utility vehicles and other heavy-duty equipment requiring Allison TES-295 or DTFR 13C180 specifications. It also meets a wide range of approvals including Voith, ZF and MAN specifications, making it suitable for a broad range of commercial vehicle transmission systems.
Physical characteristics include a kinematic viscosity of approximately 39 mm²/s at 40°C and 7.3 mm²/s at 100°C, with a viscosity index of around 168. Mobil Delvac 1 ATF has a density of approximately 0.85 g/ml at 15.6°C, a flash point of approximately 236°C and a pour point of approximately −54°C. The fluid also provides a Brookfield viscosity of approximately 8400 mPa·s at −40°C, supporting reliable lubrication performance and smooth transmission operation across a wide range of operating conditions.
