What is the suitable engine oil for the LaCrosse?
2 Answers
The LaCrosse is suitable for SAE 5W30 engine oil. The functions of engine oil include: lubrication and wear reduction, cleaning and dispersion, cooling and temperature reduction, sealing and leak prevention, corrosion and rust prevention, and shock absorption. The LaCrosse is a mid-size 4-door 5-seater sedan with body dimensions of: length 5026mm, width 1866mm, height 1459mm, and a wheelbase of 2905mm. The LaCrosse is equipped with a 1.5T engine and a 9-speed automatic manual transmission, delivering a maximum power of 124 kilowatts and a maximum torque of 250 Newton meters. It features front-wheel drive, with a front suspension using MacPherson independent suspension and a rear suspension using multi-link independent suspension.
I've been driving a Buick LaCrosse for many years, and changing the oil is quite straightforward. It's generally recommended to use full synthetic 5W-30 oil, as clearly stated in the manual, which is suitable for the LaCrosse's engine and provides excellent protection. I usually use Mobil or Castrol, and I've noticed much quieter engine starts and smoother operation. The oil change interval depends on mileage, with a recommended change every 7,500 to 10,000 kilometers—too frequent is wasteful, while too infrequent can lead to engine dust buildup. There might be slight variations for different model years of the LaCrosse; for example, older models can use mineral oil, but newer models are better off with full synthetic for peace of mind and cost savings. Remember, engine oil is no small matter—good oil can extend engine life.
