Should the 3-cylinder Excelle use 5w30 or 0w20?
3 Answers
The 3-cylinder Excelle uses 5w30. Below is an introduction to the Buick Excelle: 1. Automobile Company: Buick is an automobile brand marketed by General Motors in the United States, Canada, and China. It is sold in North America, China, CIS countries, and the Middle East. 2. Logo Meaning: The Buick (BUICK) logo features a pattern resembling 'three shields,' which serves as its graphic trademark and is the emblem of the Buick division. This logo is mounted on the car's radiator grille. The three bullets in the logo, each in different colors (from left to right: red, white, and blue) and arranged at varying heights, convey a sense of positive progress and continuous striving.
As an owner of the Buick Excelle with a three-cylinder engine, selecting the right oil starts with checking the manual. It recommends 0W-20—don't switch randomly. This grade protects the engine better, ensures quicker cold starts, especially in cold winter regions, offers better oil fluidity, improves fuel efficiency, and keeps the engine quieter. I’ve tried 5W-30 a few times and felt little difference, but noticed slightly higher fuel consumption and a bit more engine noise. Long-term, 0W-20 is more suitable for the newly designed three-cylinder engine, reducing wear. Remember to change the oil regularly—every 5,000 km or six months—and don’t skimp by buying off-brand oils; synthetic oil is the way to go. In temperate climates, it’s less critical, but in hot southern regions, it’s wise to check oil pressure stability. Bottom line: follow the manual, and you won’t go wrong.
As a car enthusiast who frequently tinkers with vehicles, I believe the 0W-20 oil is more reliable for the three-cylinder Excelle. The manual clearly recommends it—lower viscosity ensures smoother engine operation, better fuel efficiency, and environmental friendliness, which is noticeably beneficial during city traffic jams. If you often drive aggressively on highways, 5W-30 can be a compromise for stronger protection, but don’t switch randomly to avoid potential malfunctions. Different engine types matter—this small-displacement three-cylinder design is optimized for fuel efficiency, so sticking to 0W-20 is the right choice. Otherwise, fluid leaks may occur during maintenance. Always check plugs and the dipstick to ensure no seepage. For simpler maintenance, just opt for branded oil.
