What type of engine oil is best for the Changan CS55?
2 Answers
Changan CS55 uses 5W30 engine oil, with a refill quantity of 3.5 liters. Below are relevant details: 1. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. 2. Engine oil is used for lubricating internal combustion engines. Its main functions are to reduce friction and wear of moving parts, as well as to remove sludge and varnish from the engine. 3. The Changan CS55 is an SUV model equipped with a 1.5T VVT DOHC all-aluminum engine, delivering a maximum power of 115 kW and a maximum torque of 225 Nm.
I've just researched this issue, and for my CS55, 5W-30 full synthetic oil works best. I remember last winter when temperatures dropped below minus 10 degrees Celsius, the engine sounded exceptionally smooth during cold starts in the morning – the 5W's low-temperature fluidity is truly reliable. During summer highway driving, when the oil temperature rises, the 30 viscosity provides sufficient protection, even when revving above 4,000 RPM without any issues. However, be careful not to go for cheap off-brand oils. Last time I used Shell Helix Ultra, and even after 8,000 kilometers, the oil color remained quite clear. If you frequently drive on rough roads or often carry heavy loads, you might consider upgrading to 5W-40 for better high-temperature protection. Of course, the most reliable approach is to check the vehicle's manual, as requirements may vary slightly between different model years.
