What kind of engine oil should be used for CS55?
2 Answers
Changan CS55 can use Shell HX7-5w-40 synthetic engine oil. Here is some relevant information: 1. Engine oil, also known as motor lubricant, with a density of approximately 0.91×103(kg/m3), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the 'blood' of a car. Gasoline engine oils are divided into two types: mineral oil and synthetic oil, with synthetic oil further categorized into semi-synthetic and fully synthetic oils. 2. Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting new properties and making it an essential part of lubricating oil. The engine is the heart of a car, containing many metal parts that move against each other under fast speeds, harsh conditions, and high temperatures.
I remember changing the oil for the CS55 is something that requires careful consideration. Generally speaking, consulting the vehicle manual is key. For SUVs like the CS55, 5W-30 full synthetic oil is usually recommended because its viscosity is moderate and adapts to climates across China—not too thin in summer and not too thick in winter. I set the oil change interval at around 8,000 kilometers because full synthetic oil is highly durable, reducing engine wear and carbon buildup. In terms of brands, I've used Mobil 1 and Shell Helix Ultra, both with good results. However, make sure to buy genuine products and avoid cheap counterfeits. Even if you don’t drive often, the oil should still be changed every six months to prevent engine corrosion due to oil degradation. Additionally, if you're doing the oil change yourself, pay attention to checking the dipstick and oil filter—or just take it to a professional shop for peace of mind. In short, regular maintenance extends the car’s lifespan and saves you from costly major repairs.
