We do not restrict any automotive product from any retailers that carry Royal Purple consumer products. Any lack of availability of Royal Purple products at local retail stores is due to the choices made by the store owners/buyers. Retailers choose the products they stock and order for a myriad of reasons. Many times, a local retailer will special order Royal Purple products if you can provide the part number. Another option is to shop online. Several online retailers, including Amazon.com, JEGS.com, Lucky7Trucks.com, PacePerformance.com, and SummitRacing.com carry just about all Royal Purple automotive and consumer products, and they will ship directly to you.
