What is the best engine oil for the LaCrosse?
2 Answers
The LaCrosse performs best with the original 5W30 engine oil. Using oil with viscosity that is too high or too low can adversely affect the vehicle's normal operation. Taking the 2021 LaCrosse as an example, it is classified as a mid-size sedan with the following dimensions: length 5026mm, width 1866mm, height 1459mm, wheelbase 2905mm, fuel tank capacity 55L, and curb weight 1535kg. The 2021 LaCrosse is equipped with a 1.5L turbocharged engine, delivering a maximum horsepower of 169PS, maximum power of 124kW, and maximum torque of 250Nm, paired with a 9-speed automatic transmission.
I often get asked about the best oil choice for the LaCrosse. Based on my decade-long driving experience, the first step is always to check your owner's manual, which usually specifies synthetic oils like 5W-30 or 0W-20. Synthetic oils last longer and perform better, especially for mid-sized sedans like the LaCrosse, offering superior engine protection and preventing oxidation and carbon buildup under high temperatures. Why this recommendation? Because the LaCrosse uses a GM engine, and for moderate driving, 5W-30 works well in most climates, handling cold winter starts or long summer drives without issues. Personally, I've used Mobil 1 synthetic oil, changing it every 8,000-10,000 kilometers, and the engine runs incredibly smooth. Don’t overlook the importance of regular oil changes—using the wrong oil can lead to insufficient lubrication and higher fuel consumption. In short, don’t skimp on this small expense. A little effort to check the manual can save you trouble and ensure peace of mind on the road.
