What kind of oil should be used for the LaCrosse?
2 Answers
LaCrosse uses 5W30 engine oil. The number 5 indicates that it can be used at temperatures above -30 degrees Celsius, W stands for winter, and 30 represents the viscosity of the oil at 100 degrees. The higher the number, the higher the viscosity of the oil, the better its ability to withstand high temperatures, and the better its high-temperature protection performance. The LaCrosse is a model under the Buick brand, with a body length, width, and height of 5026mm, 1866mm, and 1459mm respectively, a wheelbase of 2905mm, and a fuel tank capacity of 60 liters. The LaCrosse is equipped with a General Motors 1.5T direct-injection turbocharged engine paired with a 9-speed intelligent transmission for efficient driving performance.
I've been driving my LaCrosse for six or seven years, and I know all about changing the oil. Every time I get it serviced, I use full synthetic 5W-30, and the engine runs super smooth with no lag when accelerating. The manual says 0W-20 is also fine, but I prefer a slightly thicker oil for my older car for peace of mind. Synthetic oil may be more expensive, but it lasts longer. Changing it every 5,000 miles saves money and protects the engine—don’t cut corners and wait until it’s dirty. With city traffic, oil consumption is faster, so check the dipstick regularly and keep the level in the middle. Recommended brands like Mobil or Shell, bought from official channels—don’t underestimate low-quality oil; it can easily cause leaks or carbon buildup. 5W-30 adapts well to temperature changes, with no delayed starts in winter and no thinning in summer heat. In short, maintaining the oil system properly can extend your car’s lifespan.
