Oil is crucial to your engine health. The job of the oil pan is to make sure that there is an adequate volume of oil available to lubricate your motor. If your factory Buick Rainier oil pan has been damaged or you are looking to upgrade for increased oil capacity, then aftermarket Buick Rainier oil pans are just the ticket. With an aftermarket Buick Rainier oil pan you can drive with confidence knowing that your motor has plenty of oil to stay properly lubricated. Here at Andy's Auto Sport we have a great selection of Buick Rainier oil pans for you to choose from. With everything from OEM replacements to high-performance models you are sure to find the perfect part for your needs in our extensive collection.

If you use your vehicle for competition or high performance driving then it is important to consider an upgraded Buick Rainier oil pan. With your stock oil pan, as you accelerate hard or turn a corner, oil moves away from the oil pump pickup. In high performance machines this can cause oil starvation which in turn can lead to significant internal engine damage. To solve this problem aftermarket companies have developed oil pans with internal baffles that trap oil in the area of the sump pickup to prevent oil starvation during sharp movements. High-performance oil pans are a must-have item for the competition minded enthusiast.

Q: Why buy an oil pan?
A: Custom oil pans not only make the bottom side of your engine block look great, but they also can have an impact on performance. Since the oil pan is the lowest point on the engine block, air that's passing by along the bottom of the car interfaces with the bottom of the oil pan. Aftermarket oil pans are often designed in ways that are less obstructive to that air flow.
