How Many Liters of Engine Oil Should Be Added to the Buick Excelle?
3 Answers
4.5 liters of engine oil should be added. Typically, filling to the middle between the upper and lower marks on the dipstick is optimal. The main functions of engine oil include the following points: Lubrication and Friction Reduction: Forms an oil film between two sliding surfaces to prevent friction during operation, ensuring smooth movement of components. Auxiliary Cooling: The engine generates high temperatures during operation; when oil reaches these areas, it absorbs heat and carries it away, aiding in component cooling. Cleaning: Removes carbon deposits, sludge, and worn metal particles from engine parts through circulation, returning them to the oil pan, and flushes away contaminants from the working surfaces of components via oil flow. Principles for Selecting Engine Oil: The selection principle involves first choosing the appropriate quality grade, followed by the required viscosity grade. When selecting the performance grade, it is also necessary to consider the usage environment comprehensively and apply flexibly. Opting for a higher-grade oil, though slightly more expensive, offers better overall economic efficiency.
My Excelle is the 2018 model with a 1.3T engine. During the last maintenance, the mechanic added 4.5 liters of full synthetic oil, saying this amount exactly meets the manual's standard. When changing the oil myself, I paid special attention to checking the dipstick. First, I parked the car on level ground and turned it off for ten minutes, then pulled out the dipstick, wiped it clean, reinserted it, and checked. The oil level is ideal when it's at the middle mark. Adding too much oil can make the engine feel sluggish and increase fuel consumption. My experience is to prepare a 4-liter jug and a 1-liter bottle, pour in 4.5 liters, then seal the remaining half bottle for next time. Different engine models may require different amounts; for example, older 1.5L naturally aspirated engines might only need 4.2 liters. That's why I keep the manual in the glove box after buying the car. After every maintenance, I always ask the mechanic to check the dipstick to avoid any issues.
It's been over three years since I started driving the Excelle. I remember specifically asking about the amount of engine oil needed during the first maintenance, and the 4S shop said approximately 4.5 liters. When changing the oil, the mechanic first poured in a full 4-liter bottle, started the car for a few minutes, then turned it off. After waiting for the oil to settle, he checked the dipstick and found it insufficient, so he slowly added about 0.3 liters more until it reached the middle mark. Later, I checked the manual and found that my 2020 1.0T model indeed requires 4.3-4.5 liters, with the key factor being how thoroughly the old oil is drained. Now, I always prepare 5 liters of oil in advance and save the leftover for the next use. A reminder to new car owners: learn to check the oil dipstick yourself. The most accurate reading is when the engine is cold. If the oil level exceeds the upper limit mark, drain some immediately to avoid engine damage.
