Which engine oil is best for Nissan Sylphy?
2 Answers
Nissan Sylphy performs well with mineral engine oil. The functions of engine oil are: 1. As a lubricant, it reduces friction and wear between moving parts; 2. As a coolant, it absorbs heat generated in the engine combustion chamber and piston crown, cooling the engine and preventing overheating; 3. As a sealant, it fills the gap between piston rings and cylinder liners to prevent combustion pressure leakage. The Nissan Sylphy is a 4-door, 5-seater compact sedan with body dimensions of 4631mm in length, 1760mm in width, and 1503mm in height, a wheelbase of 2700mm, a fuel tank capacity of 50 liters, and a trunk capacity of 510 liters.
I've been driving a Sylphy for several years and have used seven or eight different types of engine oil. The 1.6L naturally aspirated engine is the most worry-free. The original manual recommends 5W-30 as the most suitable, but it depends on the year. For a decade-old car like mine, using Shell Helix Ultra fully synthetic oil reduces cold start noise significantly and can lower fuel consumption by about 0.3. For the newer HR16DE engine, the Nissan fully synthetic oil from the 4S shop is sufficient, but buying Mobil EP yourself is more cost-effective. Remember not to cheap out and use mineral oil, as the VTC valve in the Sylphy is prone to sticking. During the last maintenance, sludge was found in the oil pan, which was caused by the previous owner using 20 viscosity oil improperly. For cars with over 100,000 kilometers, high-viscosity 30 oil like Idemitsu Gold is recommended, as its cleaning properties are particularly suitable for Nissan engines.
