Mobil ATF 134
Mobil ATF 134 is an extra high-performance automatic transmission fluid specifically engineered for use in modern Mercedes-Benz automatic transmissions. Formulated using carefully selected high viscosity index (HVI) base oils combined with an advanced additive system, Mobil ATF 134 provides excellent thermal stability, strong wear protection and reliable lubrication performance under a wide range of operating conditions. The fluid is designed to meet the demanding requirements of modern transmission systems, ensuring smooth operation and long service life.
One of the key advantages of Mobil ATF 134 is its excellent low-temperature performance. The fluid offers outstanding pumpability and rapid circulation at low temperatures, ensuring immediate lubrication of transmission components during cold starts. This helps reduce wear and supports smooth gear engagement, particularly in colder operating environments.
Mobil ATF 134 also provides enhanced protection against wear and component damage. The advanced additive technology forms a durable lubricating film between moving transmission parts such as gears, bearings and clutch systems. This helps minimise wear under high load conditions and contributes to extended transmission life and reduced maintenance requirements.
Another important benefit of Mobil ATF 134 is its ability to maintain consistent frictional performance. The fluid is formulated to meet the latest frictional requirements of modern automatic transmissions, ensuring smooth and precise gear shifting throughout the service interval. Stable friction characteristics help prevent shudder, improve driving comfort and support efficient transmission operation.
Mobil ATF 134 also demonstrates excellent resistance to thermal degradation and oxidation. Automatic transmissions can operate at high temperatures, particularly under heavy load or stop-start driving conditions. Mobil ATF 134 resists breakdown at elevated temperatures, helping maintain fluid integrity and ensuring reliable transmission protection over extended service intervals.
Mobil ATF 134 is specifically recommended for use in the latest generation of Mercedes-Benz 7-speed automatic transmissions and is fully approved against MB 236.14. The fluid is designed to meet the performance requirements of these advanced transmission systems, ensuring compatibility and optimal operation in approved applications.
Physical characteristics include a kinematic viscosity of approximately 29.6 mm²/s at 40°C and 6.5 mm²/s at 100°C, with a viscosity index of around 185. Mobil ATF 134 has a flash point of approximately 200°C and a pour point of approximately −51°C. The fluid also provides a Brookfield viscosity of approximately 8500 cP at −40°C and is red in colour, supporting reliable lubrication performance and smooth transmission operation across a wide range of temperatures.
