What kind of oil does the Nissan QR25 engine use?
1 Answers
Nissan QR25 engine uses 5W/40 synthetic oil. The role of engine oil: As a lubricant for the engine, engine oil continuously flows into various transmission components during engine operation, forming an oil film between friction surfaces, thereby reducing friction resistance, lowering power consumption, and minimizing component wear. Precautions for using engine oil: The selection of engine oil should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Therefore, it is advisable to choose multi-grade oil, which offers advantages such as economy, long service life, and high efficiency, providing better protection for the engine. Due to the characteristics of multi-grade oil, phenomena such as premature darkening and lower oil pressure compared to conventional oil may occur during use, which are normal.
