Recently had a motor installed in my daughter's Mazda by Johnson's Automotive. Unfortunately it was burning oil right away but ran perfectly. Contacted Johnson's and talked to Bill. He understood and had us do a oil consumption test for the next few weeks. It proved to be worthy of replacing. We took it back and they installed another motor with less miles (under warranty) and the new motor runs great and burns no oil. So far all is well. Great service and back up their work. Highly recommend Johnson's Automotive!
