Should the Emgrand GS use 5w30 or 5w40?
2 Answers
The Emgrand GS uses 5w30. The 'w' stands for winter, and the smaller the number before the 'w', the better the oil's low-temperature fluidity. The number after the 'w' represents the oil's viscosity at 100 degrees Celsius. The higher the number, the higher the viscosity, which provides better engine protection at high temperatures. Taking the Emgrand GS 2020 1.4T manual Ya Life as an example: it is a compact 5-door, 5-seat SUV with a length, width, and height of 4440mm, 1833mm, and 1573mm respectively, a wheelbase of 2700mm, equipped with a 6-speed manual transmission, and a top speed of 185 kilometers per hour.
I always pay special attention to engine oil usage guidelines, and I remember the owner's manual clearly states that the Emgrand GS recommends using 5W30. This viscosity grade is particularly friendly to turbocharged engines, especially in stop-and-go city traffic conditions. 5W40 has a slightly higher viscosity, and long-term use in new vehicles may increase fuel consumption, and the engine sound can also become muffled when climbing hills with the air conditioning on in summer. However, there are several situations where flexibility can be applied: for example, if you frequently floor the throttle for high-speed driving, or if the car has over 100,000 kilometers and shows slight oil burning, switching to 5W40 can provide better protection. The key to choosing engine oil lies in the API certification, and it is now recommended to use SP-grade oil, which is friendly to particulate filters.
