Mobil 1 FS 5W-40
Mobil 1 FS 5W-40 is an advanced full synthetic engine oil engineered to provide excellent engine protection, outstanding cleanliness and reliable performance for modern gasoline and diesel engines. Developed using high-performance synthetic base oils combined with advanced additive technology, Mobil 1 FS 5W-40 delivers strong lubrication performance and durability across a wide range of operating conditions. The formulation is designed to support modern engine technologies while helping maintain engine efficiency and long-term reliability.
One of the key advantages of Mobil 1 FS 5W-40 is its exceptional cleaning performance. The lubricant contains active cleaning agents that help prevent the formation of sludge and harmful deposits inside the engine. By maintaining clean internal engine components, Mobil 1 FS 5W-40 helps ensure consistent lubrication performance and efficient engine operation throughout the oil service interval. This high level of cleanliness helps support long engine life and improved reliability.
Mobil 1 FS 5W-40 also provides excellent protection against engine wear. The advanced additive system forms a durable lubricating film between moving metal surfaces, helping to reduce friction and minimise wear. This protection is particularly important for high-performance engines that operate under increased loads and temperatures, including turbocharged and multi-valve fuel injected engines.
Another important benefit of Mobil 1 FS 5W-40 is its strong resistance to thermal and oxidative degradation. Engine oils are exposed to high temperatures and mechanical stress during operation, which can lead to oil breakdown over time. The advanced synthetic formulation helps resist oil ageing and maintain viscosity stability throughout the oil service interval, ensuring reliable engine protection even in demanding operating environments.
Mobil 1 FS 5W-40 also offers excellent low-temperature performance. The oil flows quickly during cold starts, allowing rapid lubrication of critical engine components and helping reduce wear during engine start-up. Fast oil circulation during start-up supports reliable engine operation and helps extend engine life, particularly in colder climates. In addition, the lubricant’s friction-reducing properties can help contribute to improved fuel efficiency while maintaining strong engine protection.
Mobil 1 FS 5W-40 is recommended for a wide range of modern passenger vehicles including high-performance gasoline engines and certain diesel engines without diesel particulate filters. The lubricant meets or exceeds numerous industry and manufacturer specifications including BMW Longlife-01, Mercedes-Benz MB 229.3 and MB 229.5, Renault RN0700 and RN0710, Porsche A40 and Volkswagen VW 502 00 and VW 505 00 approvals, making it suitable for many European vehicle platforms.
Physical characteristics include a kinematic viscosity of approximately 81 mm²/s at 40°C and 13.2 mm²/s at 100°C. Mobil 1 FS 5W-40 has a density of approximately 0.8408 g/ml at 15.6°C, a flash point of approximately 241°C and a pour point of approximately −40°C, supporting reliable lubrication performance and strong engine protection across a wide range of operating conditions.
