What type of engine oil is the best for Xuanyi car? What type of engine oil is the best for Xuanyi car? Nissan Sylphy uses original engine oil 5W30 as the best engine oil. For 5W30 and 0W20, the new Sylphy prefers 5W30, which has better fluidity at low temperature and can be applied to lower temperature environment. The following are the precautions for the use of engine oil: 1. Selection of engine oil: The selection of engine oil should be based on the requirements of the engine. Do not use high-grade engine oil on lower engines, and do not use low-grade engine oil on higher engines. Select the engine oil that matches the engine. 2. Multistage engine oil: Multistage engine oil should be selected. Multi-grade engine oil has the advantages of saving, long service life and high efficiency, which can protect the engine well. 3. Amount of oil added: The amount of oil should be slightly lower than the scale on the dipstick. Don't pack it too full. Too much oil will not only increase the rotational resistance of the crankshaft, but also reduce the output power of the engine. Even those excessive engine oil will escape into the combustion chamber to participate in combustion, which will lead to blue smoke when the vehicle burns engine oil and even increase fuel consumption. 4. Choose engine oil with different viscosities according to engine working conditions: if the engine is in good condition and the seasonal temperature is low, use engine oil with lower viscosity; If the engine is badly worn and the seasonal temperature is high, use oil with high viscosity. 5. Don't mix engine oil: If you replace medium and high-grade engine oil with ordinary engine oil, you should drain the original engine oil first and clean the lubrication system. Do not mix engine oil. @20 19
