In general, you should get an oil change every 5,000 miles or six months, whichever comes first. However, there are several factors that can affect how frequently your Buick Enclave or GMC Sierra 1500 needs an oil change, such as your driving habits and the age of your vehicle. Unsure of when you need your next oil change? Stop by our Indiana Buick dealer to speak with one of our service techs, and we'll take care of any maintenance your car, truck or SUV may need.
