What type of oil does the new Buick Regal use from the factory?
2 Answers
The new Buick Regal uses 5W-30 oil from the factory. Winter oil grades: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W represents winter. The smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. Summer oil grades: 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature. All-season oil grades: 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, 15W-20, 20W-40, 20W-50. The smaller the number representing the winter part, the lower the applicable minimum temperature.
I've been driving the new Buick Regal for almost a year now. The manufacturer recommends using 0W-20 full synthetic oil with the GM Dexos certification logo. This oil flows quickly in cold weather, making engine starts super smooth, while also reducing engine wear in hot weather. The manual suggests changing the oil every 8,000 kilometers or every six months, but I've found that if daily commuting involves a lot of traffic congestion, it's better to change it a bit earlier to avoid carbon buildup. I tried using conventional oil before, and the engine noise increased while fuel consumption also went up a bit. Remember to buy genuine bottled oil; don't cheap out on off-brand products, or the warranty might be at risk. Regularly checking the oil level during maintenance to keep it in the green range can extend the car's lifespan, saving money and giving peace of mind.
