Your car is essentially made of parts and fluids. That being said, buying new replacement parts and fluids can be difficult. There are thousands of different automotive parts and fluids brands out there, so why choose certified Buick OEM parts or GMC OEM parts? Let us explain!

Certified parts and fluids are those that have been approved by the manufacturer. These parts have been made by the manufacturer or a company that partners with them. Often, these parts are the ones used to build your vehicle. The same goes for fluids, like oil and coolant. These parts and fluids are guaranteed to fit your specific model and last the test of time. Aftermarket parts can’t guarantee the same. These parts are often made to fit a variety of vehicle models by multiple manufacturers. Buying certified parts and fluids are going to help make sure that you have a part of a fluid that is going to work for your particular car. Making sure you have parts that are certified to work with your car is the best way to make sure you are going to get a part that will serve the intended purpose and that your money is well spent.

Using parts that are from a third-party parts manufacturer or from a company that's not certified can go one of two ways. The parts may work well and they may serve the purpose you're looking for — or they may not. Parts and fluids that are not certified may or may not work, and are not guaranteed to work with your car while those that are certified are guaranteed. It's an important distinction to make as parts that don't fit are going to have to be sent back, or are going to have to be ordered again from another company to help make sure they're going to work.
