The Buick LaCrosse requires 4.5L of engine oil. Below are the detailed specifications of the Buick LaCrosse: 1. Exterior: The Buick LaCrosse adopts Buick's latest family design language, featuring smooth and elegant body lines with a highly dynamic body proportion. The wing-shaped full LED automatic sensing headlights utilize advanced light curtain technology. 2. Powertrain: Equipped with a 1.5T SIDI direct-injection turbocharged engine paired with a 9-speed HYDRA-MATIC intelligent transmission, it delivers robust and smooth power, with characteristics of high torque at low RPM and high power at high RPM. It achieves a maximum power of 124kW at 5600rpm and a maximum torque of 250Nm across a broad RPM range of 1700-4400rpm, with a fuel consumption of just 6.5L per 100 kilometers.

I've been driving my Buick Regal for many years, and each oil change requires about 5.5 liters, depending on the engine. For example, the 2.0T engine might need between 5 to 5.5 liters. Before refilling, always check the dipstick - the ideal oil level when cold is in the middle of the marked range, as too high or too low can damage the engine. I recommend not skimping on quality; use premium full synthetic oil. If a 5-liter bottle isn't enough, top it up slightly but avoid overfilling to prevent oil pressure issues. The oil change interval is crucial too - I typically service it every 8,000 to 10,000 kilometers while checking the filter, as low oil level might indicate a clogged filter rather than oil shortage. Paying attention to these details can significantly extend engine life.

As someone who frequently works on cars, I must say the Buick LaCrosse typically requires an oil capacity of 4.5 to 6 liters. For instance, older models with a 3.0L engine take about 5.7 liters, while newer turbocharged versions require slightly less. The key is accurate measurement to avoid major issues—overfilling can clog the system, leading to engine smoke or oil burning, while underfilling causes insufficient lubrication and overheating damage. I always remind car owners not to cut corners; during oil changes, they should personally monitor the measuring cup's markings or check the precise figures in the user manual. During maintenance, it's also wise to replace the old oil filter, preferably with an OEM-matched part. Developing a habit of regular oil checks, especially after long trips, helps monitor fluid level changes. This approach saves money and ensures safety.

My LaCrosse has been in use for over five years, and I'm quite familiar with changing the engine oil. The engine requires approximately 5 liters as the standard amount. When topping up, I usually start with a 4-liter container first, then gradually add more until the fluid level is just right. Never neglect checking the dipstick, as it can easily affect performance. I stick to changing the oil every six months or 5,000 kilometers, ensuring the oil level remains stable for peace of mind. New car owners are advised to follow the user manual for precise measurements.
