What type of engine oil is suitable for the Venucia D50?

The Venucia D50 is equipped with a 1.6L naturally aspirated engine, and it is recommended to use 5W-30 semi-synthetic engine oil. Depending on the ambient temperature, 0W-30 oil can be used in winter, and 0W-30 oil can also be used in summer. Key factors to consider when selecting engine oil: Engine oil should be selected based on the requirements of the engine. 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. Precautions for changing engine oil: The engine must be preheated before draining the oil. At this time, the oil is thinner and flows more easily, helping to carry away impurities and ensuring thorough drainage. Remember not to drain the oil when the engine is cold, and replace the oil filter simultaneously. The old oil filter may be clogged with impurities, which can slow down oil flow and reduce engine lubrication. The amount of oil added should be measured, and for some vehicles, the oil level can be checked using the dipstick to ensure it is appropriate. Functions of engine oil: The primary function of engine oil is lubrication. During the lubrication process, the oil is gradually consumed, and impurities and deposits can form, affecting lubrication effectiveness. Engine oil also has a cleaning effect, but some residues may remain in the engine during cleaning. The anti-rust property of engine oil is also very important. While oil cannot completely prevent oxidation, it can reduce it. Good sealing enhances mechanical efficiency, but prolonged use can lead to chemical reactions that weaken sealing. Cooling is another function of engine oil, but its cooling effect diminishes over time with prolonged use.
I've driven the Venucia D50 for three years. This car uses Nissan's HR16 engine, and the factory recommends 5W-30 viscosity as the safest option. Mineral oil can also be used, but semi-synthetic offers better value for money, with an oil change interval that can last up to 7,500 km. Remember to choose API SN or higher standards, Shell HX6 or Castrol Magnetec are both good options. In northern winters, it's best to use 0W-grade oil for smoother cold starts. The key is not to cheap out on off-brand oils, as engine noise may increase, and fuel consumption could spike by 0.5L. Last time I tried a trending internet-famous oil, the engine felt sluggish after just 3,000 km, so I quickly switched back to major brands.
Having repaired cars for ten years, I've seen too many cases of improper oil usage. The Venucia D50 shares the same engine as the Nissan Sylphy, so it requires low-ash oil. I recommend GF-5 certified 5W-30 semi-synthetic oil, with Idemitsu Gold or Great Wall Dry series being good choices. For older cars with over 80,000 kilometers, you can upgrade to 5W-40. Three key points to check: whether the oil cap specifies A5/B5, the ACEA standard recommended in the maintenance manual, and the local temperature. Using 10W oil in Guangdong summers is fine, but Heilongjiang must use 0W. Don't blindly trust imported oils—using the wrong viscosity can damage the VTC valve.
