How many liters of engine oil should be added to the new Buick GL8?

The new Buick GL8 requires approximately 4 liters of engine oil. Standards for adding engine oil: Generally, the engine oil should be filled between the upper and lower marks on the dipstick, and it should not be below the middle mark. This is because high-speed driving can cause the engine to heat up, making the oil thinner. If the oil level is too low, it will reduce lubrication and cooling effects. Practice has shown that filling the oil to about 1/4 below the upper limit is ideal. Additionally, factors such as the oil type, season, climate, engine displacement, and technical performance must be considered. Therefore, it is best to choose a professional automotive maintenance center where experts can carefully assess the vehicle, select the appropriate oil, and perform the maintenance with precision to prevent potential issues. Hazards of overfilling engine oil: Excessive engine oil increases the crankshaft's rotational resistance, reducing the engine's output power. Moreover, the excess oil can enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emission, and increased fuel consumption. The residue from burned oil (mainly composed of carbon, which is very hard) can accumulate on the combustion chamber walls, reducing the chamber's space and lowering the engine's compression ratio. This also accelerates wear on the cylinders and pistons, thereby shortening the vehicle's lifespan.
I remember for my new Buick GL8, every time I get it serviced at the 4S shop, the technician says it takes about 5.0 liters of engine oil. This is for the common 2.0T engine, but if you have a different model like a V6, it might be slightly more or less. It's best to check the maintenance section of the owner's manual to avoid overfilling or underfilling—too much can cause carbon buildup, and too little might damage the engine. Also, when changing the oil, it's recommended to choose the right viscosity grade, such as 0W-20 full synthetic oil, which benefits both fuel efficiency and engine longevity. Personally, I change the oil every 8,000 kilometers—it's not expensive for maintenance but saves a lot of trouble. In short, referring to the manual or confirming with a professional shop is the safest approach, especially since this car's engine is quite sophisticated.
