Can the Changan CS75 use 5w40 engine oil?
2 Answers
Changan CS75 can use 5w40 engine oil, but the manufacturer recommends using 5W30 engine oil for better performance as per the manufacturer's instructions. The specific details are as follows: Using 5w-40 engine oil can make the engine quieter, but it will increase fuel consumption. 5W-30 has better fluidity than 5w-40, which helps in reducing fuel consumption and dissipating heat from the engine more quickly. Related information is introduced as follows: The difference between 5w30 and 5w40 engine oil is that the higher the viscosity of the engine oil, the more fuel the engine consumes, and the louder the noise, but the better the sealing performance. Therefore, when choosing engine oil viscosity, the age of the vehicle should also be considered. The engine components of a new car have very small gaps, so engine oil with lower viscosity should be chosen, while vehicles with severe engine wear should choose engine oil with higher viscosity.
I've been driving the Changan CS75 for several years and have tried several types of engine oil. Using 5W40 is fine, especially in hot summer areas, as it provides better engine protection and reduces noise. However, the manual recommends 5W30 or 0W30, which offer better fluidity during cold starts. Personally, I suggest sticking to the factory specifications, but before switching to 5W40, check the oil pressure and viscosity compatibility to avoid increased fuel consumption or accelerated engine wear. In the long run, maintaining oil changes every 5,000 kilometers and choosing the right viscosity can extend engine life. Remember to check the oil condition—when it turns black, it's time to change it, saving money and ensuring safety.
