What Type of Oil is Suitable for the Changan CS75?
2 Answers
For the Changan CS75, the original SL-grade 5W-30 oil is sufficient. The steps for adding oil to the Changan CS75 are as follows: 1. Run the engine until it reaches operating temperature. Then use a jack to lift the vehicle, engage the handbrake, and secure the front wheels with wooden wedges. 2. Place an old oil container under the oil pan, locate the oil drain plug, and slowly loosen it, being careful not to come into contact with the hot oil. Allow the oil to drain for a while, then check the drain plug and reinstall it, ensuring not to overtighten to prevent damage to the oil pan. 3. Move the oil container beneath the oil filter. Use an oil filter wrench to loosen the filter, then unscrew it by hand. If the filter is still hot, remember to wear gloves. 4. Apply new oil to the gasket of the new filter. If the filter is installed vertically, you can pour some new oil into the filter to reduce dry friction during the next engine start. Screw the filter in by hand and tighten it according to the instructions (usually an additional 3/4 turn after hand-tightening). 5. Pour the new oil into the oil pan, referring to the user manual. Use a funnel to avoid spilling oil on the engine exterior. Check for leaks underneath the engine. If there are no leaks, lower the vehicle, check the oil dipstick, and start the engine. The dashboard warning light should turn off immediately. Finally, turn off the engine and recheck the oil level. Dispose of the old oil and filter according to local regulations.
For the Chang'an CS75, I've checked the owner's maintenance manual, which recommends using fully synthetic 5W-30 engine oil. The advantage of synthetic oil is better lubrication, resulting in smoother engine operation, especially for the CS75's turbocharged engine. It reduces friction and wear, preventing overheating. Fully synthetic oil has strong fluidity at low temperatures, ensuring quick starts, and doesn't degrade at high temperatures, extending the oil change interval. The manual suggests changing it every 8,000 kilometers. I use genuine Shell or Mobil oil, and I feel the engine noise is reduced, with stable power response. Don't try to save money by buying counterfeit products, as this may accelerate component aging. Additionally, remember to regularly check the oil dipstick, keeping the oil level between the marked lines, especially if you frequently drive short distances—it's best to change it every 5,000 kilometers.
