What type of engine oil should be used for Buick LaCrosse maintenance?
2 Answers
Buick LaCrosse maintenance uses 5w30 engine oil, which offers a balanced performance in lubrication, cleaning, and cooling, making it a commonly used engine oil type in the automotive market. For older models, 0w40 engine oil can also be used, as its higher viscosity helps the engine perform better. The LaCrosse is equipped with advanced intelligent driving assistance technologies, providing 11 smart driving assistance features including PD pedestrian recognition, LKA lane keeping, ACC adaptive cruise control, and CMB collision mitigation. The newly added 360-degree panoramic camera comes with a built-in dashcam function, offering a comprehensive view of the surrounding environment to support safe driving.
I've been driving a Buick LaCrosse for many years and always use 5W-30 full synthetic oil for maintenance. It feels most suitable for this car's engine, with quick cold starts and no worries about freezing in winter. I recommend choosing brands with dexos certification, such as Mobil or Castrol, to avoid counterfeit products. Changing it every 5,000 kilometers or six months is a safe practice to prevent carbon buildup and wear. I usually check the oil level myself, keeping it in the middle range of the dipstick—never too full or too low, as it affects performance. For newer LaCrosse models, I've heard that 0W-20 oil is more fuel-efficient, but my older car still runs better with 5W-30 for safety. As an extension, during maintenance, it's not just about changing the oil; you should also check the air filter and coolant to prolong the car's lifespan, saving both money and hassle.
