What type of engine oil is best for the Changan CS35?
4 Answers
For the Changan CS35, it is recommended to use SL-grade 5W-30 viscosity engine oil. The required oil volume is 3.4L. After filling, the oil level on the dipstick should be between the MIN and MAX marks, neither below MIN nor above MAX. Note that engine oil should only be added when the engine is cool. Relevant details are as follows: 1. The '5W' indicates low-temperature viscosity; the smaller this number, the better the oil's fluidity. The '30' represents high-temperature viscosity; the larger this number, the higher the oil's viscosity and the better its sealing properties. 2. Higher oil viscosity is not always better. If the oil's viscosity is too high, it can also affect the engine. Higher viscosity means relatively poorer fluidity, which may prevent the oil from promptly covering all engine components, thus failing to fully utilize the oil's functions.
I've repaired countless cars, and for the CS35 engine, I highly recommend using 5W-30 synthetic oil as it's the most suitable. The manual specifies this viscosity for optimal engine protection. When changing oil, don't just look at the price—choose reputable brands like Shell or Mobil's full synthetic options. They offer high purity and excellent anti-wear performance, especially in urban stop-and-go traffic where oxidation resistance is crucial. Change the oil regularly every 8,000 km, and avoid cheap off-brand oils to prevent costly engine repairs down the line. I've seen many owners neglect this, only to end up with overheating issues. This oil grade ensures quick cold starts in winter and maintains proper viscosity in summer heat, keeping your car running smoothly and fuel-efficient. Always check the dipstick to ensure oil level stays between min-max marks—this simple habit significantly extends vehicle lifespan.
I've been driving the CS35 for two or three years and have tried different engine oils. I found that 0W-20 full synthetic is particularly good, with quick ignition in winter and low fuel consumption, making daily commuting in the city very easy. If you often drive on highways, 5W-30 is also fine, as it reduces engine noise. I've used Shell's full synthetic oil, changing it every six months, which is quite hassle-free, cost-effective, and protects the engine. It's suitable for both new and old cars, and with good oil, the engine runs smoothly. Don't forget regular maintenance and changing the filter for better results. Personally, I think investing in good engine oil is worth it!
For our family using the CS35 to take the kids to school, safety is the top priority. The manual recommends using synthetic oil 5W-30, and I always follow the standard by choosing full synthetic, like the reliable brand Castrol, to protect the engine and reduce the risk of malfunctions. Economically speaking, it's more expensive but durable and requires fewer changes, saving money in the long run. Remember to change the oil every 10,000 kilometers or once a year, and check it early if the oil color darkens. This way, the engine runs smoothly, ensuring a safe and worry-free trip when taking the kids out.
