It is essential to choose the correct grade, quality, and viscosity engine oil to ensure satisfactory engine life and performance. Mobil 1 (0W-40) (100% synthetic) is the factory fill oil. The VR38 engine with its plasma-sprayed bores was developed using this oil. NISSAN cannot ensure proper engine operation and durability if other 0W-40 synthetic oil is used. If Mobil 1 (0W-40) is not available, Mobil 1 (10W-40) (100% synthetic) may be used; however, some performance loss may be noticed.
Using an engine oil other than that specified could adversely affect the engine.
