What type of oil does the Senova D50 use?
2 Answers
Models equipped with the 1.5L naturally aspirated engine use 30-viscosity full synthetic oil, while models with the 1.5L turbocharged engine use 40-viscosity full synthetic oil. Here is an introduction to engine oil: 1. Full synthetic oil: The base oil of this type of oil is artificially synthesized. The molecular size and shape of full synthetic oil are nearly identical, providing superior lubrication performance and a longer service life. 2. Engine oil is referred to as the "blood" of the engine. Inside the engine, it not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. 3. During normal engine operation, the oil forms a stable film on the surfaces of various engine components, preventing direct contact and friction between parts. 4. If the oil viscosity is too low, it cannot form a stable film, which will accelerate engine wear. If the oil viscosity is too high, the resistance during engine operation increases, negatively affecting power output and fuel economy.
Regarding the engine oil for the Senova D50, I always recommend using 5W-30 full synthetic oil. This viscosity is suitable for most regions, ensuring easy cold starts in winter and providing excellent engine protection during hot summers. Proper engine lubrication depends on the right viscosity—oil that's too thick makes cold starts difficult below freezing, while oil that's too thin leads to poor sealing in hot weather. You should change the oil every 7,500 kilometers or so; don't wait until 10,000 kilometers, as delayed changes accelerate internal wear and shorten engine life. I've tried mineral oil before and found that synthetic oil offers better cleaning performance and significantly reduces noise. Recommended brands include Mobil or Shell—they may be pricier but are more reliable. As a side note, always check the air filter during oil changes; otherwise, dirt mixing into the oil can cause worse problems. In extremely cold regions, consider 0W-30 oil for better adaptability—safety first, don't skimp on this small expense.
