1 Answers
The Buick LaCrosse uses 5W30 engine oil. This type of oil offers a balanced performance in lubrication, cleaning, and cooling, making it one of the most commonly used engine oils in the automotive market. For older models, 0W-40 oil can also be used. This oil has higher viscosity, which helps the engine operate more efficiently. Additional information: 1. Engine oil, or engine lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion protection, as well as shock absorption. 2. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives are used to compensate for and enhance the base oil's performance shortcomings, providing additional beneficial characteristics, making them a crucial part of the lubricant.
