What kind of engine oil is suitable for the Buick Excelle?
1 Answers
The Buick Excelle 1.4T uses Mobil 1 5W-30 fully synthetic engine oil. The Buick Excelle 1.5L uses the original 5W-30 semi-synthetic engine oil. 5W represents the low-temperature viscosity of the engine oil, while 30 represents the high-temperature viscosity. Below is an introduction to engine oil: 1. Compared to 0W20, 5W30 has different high and low-temperature performance. 0W20 has better low-temperature fluidity and can be used in lower environmental temperatures, while 5W30 offers better high-temperature protection performance with higher viscosity. Although it increases fuel consumption, 5W30 is more suitable for the Excelle's engine requirements. 2. For engine oil labeled 5W-30, this grade generally meets the winter and summer usage needs in China. In hotter regions, 5W-40 can be used. Summer oil grades are 20, 30, 40, 50, and 60, with higher numbers indicating greater viscosity and suitability for higher maximum temperatures. 3. Naturally aspirated engines have lower requirements for engine oil and can use mineral or semi-synthetic oil. Compared to naturally aspirated engines, turbocharged engines are more precise and operate under harsher conditions, requiring higher-performance engine oil with better fluidity, preferably fully synthetic oil.
