What type of engine oil is suitable for the Changan CS15?
2 Answers
Changan CS15 can use semi-synthetic oil or mineral oil. Here is some relevant information about Changan Automobile: 1. Historical Background: The predecessor of Changan Automobile was the Shanghai Arsenal, established in December 1862 (the first year of the Tongzhi reign of the Qing Dynasty) by Li Hongzhang, a key figure in the Self-Strengthening Movement, who commissioned British officer Halliday Macartney and Chinese official Liu Zuoyu to set it up in a temple outside Songjiang, Shanghai. 2. Powertrain Development: The company possesses eight core R&D capabilities in powertrain: engine design, transmission development, CAE simulation, NVH evaluation, powertrain control, testing and prototyping, performance development, and vehicle integration.
Choosing engine oil for the Changan CS15, I've been driving this car for three years and feel that viscosity is the most critical factor. The manufacturer's manual recommends 5W-30, which is the safest choice—it won’t be too thin in summer heat and ensures smooth cold starts in winter. I've tried several brands, and Mobil 1 full synthetic is the most durable, staying clear even after 8,000 kilometers, with noticeably quieter engine noise. If you're on a budget, Shell semi-synthetic offers good value with strong cleaning performance, ideal for stop-and-go city driving. Don’t cheap out on no-name oils—a friend used low-quality oil last year and ended up with severe engine carbon buildup, costing repairs equivalent to five years of premium oil. Remember to check the oil filter during oil changes; it costs just a few bucks but protects the entire lubrication system.
