What type of engine oil is recommended for Changan Oushang?
2 Answers
Changan Oushang recommends using fully synthetic engine oil with a viscosity grade of 5W-30. Advantages of synthetic engine oil: Synthetic engine oil has a longer replacement interval. The minimum standard for fully synthetic oil replacement is 10,000 kilometers. There are also high-performance pure imported fully synthetic oils that can last between 10,000 to 15,000 kilometers before needing replacement. The true performance of these oils only starts to show after running 10,000 kilometers. Engine oil viscosity: The viscosity of engine oil is often indicated using the SAE grade classification. SAE stands for the "Society of Automotive Engineers" in English. For example: SAE 5W-40. The smaller the number before the "W," the better the low-temperature fluidity of the oil, indicating it can be used in lower temperatures. 5W means the oil is suitable for use in temperatures as low as -30 degrees Celsius.
I've been using Changan Oshan for several years and found that it generally recommends 5W-30 oil, especially synthetic oil, which provides better lubrication and protection. Why is that? When designing this engine, urban road conditions and daily driving were taken into consideration. The viscosity of 5W-30 performs stably at medium and low temperatures, ensuring quick starts and fuel efficiency. After switching, I noticed smoother acceleration and slightly lower fuel consumption. However, each model is different, so you should check your car's manual. For example, Oshan X7 and Z6 might have slight differences, and some newer models even support 0W-20. Never use other oil types randomly to avoid component wear. For routine maintenance, changing the oil every 5,000 kilometers or six months is crucial—don’t delay beyond 10,000 kilometers. Choose reputable brands like Shell or Mobil, which are affordable and easy to buy online. Remember, good oil extends engine life, saving you money and hassle.
