In order for your 2015 GMC Sierra 1500 to operate smoothly, it's crucial to use high-quality 5W-30 oil and ensure that it has a capacity of 6 quarts. Running into issues with the oil is inevitable at some point. A common problem to watch out for is a strong burning smell, which must be addressed promptly to prevent potential explosions. Poor quality oil can lead to engine failure, indicated by knocking noises and decreased gas mileage. It's important to schedule an oil change every 5,000 to 10,000 miles to avoid engine complications. Failure to do so can result in serious problems with the vehicle's performance.
