Mobil 1 C40 GT 0W-40
Mobil 1 C40 GT 0W-40 is an advanced full synthetic engine oil specifically engineered to deliver exceptional lubrication performance and protection for high-performance Porsche GT engines. Developed through over 25 years of collaboration between Mobil and Porsche, this specialised formulation has been designed to meet the demanding lubrication requirements of high-performance engines operating under extreme conditions. Mobil 1 C40 GT 0W-40 provides outstanding wear protection, high-temperature stability and engine cleanliness to support optimal performance in motorsport-inspired engines.
One of the key advantages of Mobil 1 C40 GT 0W-40 is its outstanding high-temperature thermal and oxidation stability. High-performance engines such as those used in Porsche GT models operate at extremely high temperatures and mechanical loads. The advanced synthetic formulation used in Mobil 1 C40 GT 0W-40 helps resist oil degradation and maintain lubricant stability throughout the oil drain interval. This resistance to thermal breakdown helps ensure consistent protection and reliable lubrication performance during demanding driving conditions.
Mobil 1 C40 GT 0W-40 also delivers excellent oil film strength and wear protection under extreme operating conditions. The carefully balanced additive system and high-performance synthetic base oils help form a strong lubricating film that protects critical engine components such as pistons, camshafts and bearings from wear. This strong oil film thickness ensures reliable protection even during high-speed driving, high load operation and elevated engine temperatures.
Another important benefit of Mobil 1 C40 GT 0W-40 is its ability to maintain engine cleanliness. The formulation contains active cleaning agents designed to help prevent sludge formation and control deposits within the engine. Maintaining engine cleanliness helps ensure optimal lubrication of moving components while supporting consistent engine performance and efficiency over time.
Mobil 1 C40 GT 0W-40 is specifically designed for Porsche GT engines requiring the Porsche C40 GT specification. The lubricant is required for a range of high-performance Porsche models including the 911 GT3, GT3 RS, GT3 Cup, GT3 R, 911 Speedster, 911 RSR and several GT variants of the 718 Cayman and Spyder platforms. This specialised oil has been engineered to support the performance and durability requirements of these advanced engines while maintaining optimal protection during extreme driving conditions.
Mobil 1 C40 GT 0W-40 also offers enhanced frictional characteristics that can help support improved engine efficiency while maintaining strong wear protection. The advanced formulation delivers a balanced combination of performance, protection and stability that supports both track-focused and high-performance road driving applications.
Physical characteristics include a kinematic viscosity of approximately 72 mm²/s at 40°C and 13.8 mm²/s at 100°C, with a viscosity index of around 199. Mobil 1 C40 GT 0W-40 has a density of approximately 0.846 g/ml at 15°C, a flash point of approximately 230°C and a pour point of approximately −48°C. The oil also provides a high-temperature high-shear viscosity of approximately 3.8 mPa·s at 150°C and a total base number of approximately 8.3 mgKOH/g, supporting reliable lubrication performance and engine protection across extreme operating conditions.
