What kind of engine oil is suitable for Changan CS75?
3 Answers
Changan CS75 is suitable for Changan's original SL-grade 5W-30 engine oil, with each refill not exceeding 4.5L. The introduction to the engine oil used for Changan CS75 is as follows: Taking the 5W-30 grade as an example (the specific grade can be seen on the oil barrel), W stands for winter, which is the abbreviation of the word Winter; The number 5 before W represents the viscosity of the engine oil in a low-temperature state, and the smaller the number, the better the fluidity of the engine oil in a low-temperature state. 2. The number 30 after W represents the viscosity and high-temperature shear resistance of the engine oil at 100 degrees Celsius, and the larger the number, the more heat-resistant the engine oil is.
I've been driving the Changan CS75 for several years now, and I think the most important thing is to refer to the owner's manual. This car usually comes with a 1.5T engine, and the manufacturer recommends using 5W-30 full synthetic oil, such as Mobil or Shell, because it can withstand high temperatures and protect turbocharged components. I mostly drive in the city, and during heavy traffic for commuting, the engine load is high. Full synthetic oil helps reduce wear. If you frequently drive on highways or in rural areas, you can opt for a higher viscosity oil like 0W-40 to handle complex road conditions. Remember not to skimp on cheap, low-quality oil to avoid carbon buildup or increased fuel consumption. Regular oil changes are crucial—I usually change it every 5,000 kilometers to keep the engine running smoothly. Overall, the manual is the authoritative reference, so it's best to follow its recommendations and not overthink it.
As a new CS75 owner, cost-effectiveness is my top priority when choosing engine oil. This car's engine typically suits 5W-30 viscosity grade - just pick an API-certified brand, no need for premium full synthetic oils. I've tried domestic brands like Great Wall or KunLun which offer good performance at reasonable prices. If you drive gently without frequent high-speed runs, semi-synthetic or mineral oils work fine too - it really depends on driving habits. I prefer changing oil in spring to avoid extreme temperature fluctuations affecting viscosity. While saving on oil costs, don't forget to check the filter - replace if dirty, otherwise you're wasting good oil. Monthly short trips help warm up the engine and extend oil life. Simply put, affordable practicality matters most - don't blindly follow premium product trends.
