What kind of engine oil should be used for the 2021 Buick Excelle?
3 Answers
The original engine oil for the 1.4T Buick Excelle is Mobil 1 5W-30 full synthetic oil. Below is a related introduction to the Buick Excelle: 1. Positioning: The new Excelle adheres to Buick's "dynamic and smooth" design language, drawing inspiration from the classic elements of the Riviera concept car. Its body styling is sporty yet dignified, showcasing a style that is both grand and simple, elegant and dynamic. 2. Exterior: The new wing-shaped chrome-plated front grille, combined with black piano vertical grilles and high-gloss chrome-plated wing grilles, naturally draws the visual focus of the front to the car emblem. At the same time, the wing grille extends horizontally to the headlights on both sides, enhancing the horizontal visual effect and overall sense of the front.
My 2021 Buick Excelle 1.3T has been running for two years, and the maintenance manual requires 5W-30 oil with dexos1 certification. I've tried several oils, and the original fully synthetic oil from the 4S店 is the most reliable, with noticeably less noise during cold starts. Mobil 1 Extended Performance is also good, but after running for 7,000 kilometers, the acceleration sound starts to become muffled. Once, I tried a cheap non-certified mineral oil, and the fuel consumption increased by half a liter, with the engine always making a ticking sound. Since then, I've been using Shell Helix Ultra with GM certification, changing it every 11,000 kilometers, which is very worry-free, especially because it doesn't produce annoying sludge. Even in winter at -15°C, it starts right up, and in summer, the power doesn't drop when running the AC at high speeds.
The most accurate way is to check the engine compartment nameplate and the owner's manual. Both the 2021 Excelle 1.5L naturally aspirated and 1.3T mild hybrid models clearly specify 5W-30 viscosity oil, especially look for the dexos1 Gen2 certification on the oil container. Don't try to save money by using uncertified oil - last time at the repair shop, I saw an Excelle that used off-brand oil which clogged the VVT valve, costing 3,000 yuan for a major overhaul. Turbo engines must use full synthetic oil, and I recommend changing it precisely at 7,500 km intervals. Don't arbitrarily use 0W-20 oil that's marked on the oil cap of newer models - older engines with larger clearances will actually burn thinner oil. Actual tests show that with 5W-30 full synthetic oil, power output remains stable even when oil temperature reaches 100°C.
