What type of oil does the Buick Excelle use?
3 Answers
Buick Excelle uses 5w30 engine oil. The following is an introduction to engine oil: Engine oil: Engine oil, also known as engine lubricant, is composed of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil, providing certain new properties, making it an important part of lubricating oil. Without engine oil, the engine cannot operate normally. Functions of engine oil: Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat.
My Buick Excelle has been running for four or five years, and I'm particularly meticulous about the engine oil. I usually recommend the 5W-30 grade, which must also meet General Motors' Dexos1 certification. I stick to this specification for every maintenance session because the 5W-30 viscosity is suitable for all-weather conditions—preventing overheating in summer and ensuring quick starts in winter, avoiding engine cylinder scoring. I've tried other brands myself, but the engine noise increased and fuel consumption rose, so I quickly switched back to the proper one. I check the engine oil every 5,000 kilometers or six months, ensuring the dipstick level is in the middle and the color isn't too dark. Using the right oil long-term is good for the car, reducing carbon buildup and wear, which can save on major repair costs. I'm very certain about this—it's even written in the maintenance manual, so don't overlook the details.
As a DIY car enthusiast, I've found that choosing 5W-30 oil with Dexos1 certification is crucial for the Buick Excelle. This ensures oil purity and high-temperature resistance. When changing oil, I prefer warming up the engine for a few minutes before starting. Then I loosen the drain plug at the bottom to remove old oil, replace the filter, and pour in new oil steadily. The 5W-30 synthetic oil flows well, preventing cold-start wear, and DIY operation saves service fees. But avoid off-brand oils or excessively high viscosity to prevent carbon buildup and engine damage. My experience shows that regular maintenance with clear oil checks ensures proper lubrication, making the engine reliable and durable.
