    Be sure to replace the bushing around the drain plug when doing an oil change. The dealer where I bought my car was in a panic over the big oil leak my car had. I tood them I would take the risk at $6K. The new bushing came with the filter and cured the problem. They said they had their serive department look it over and it was nothing more than a power steering hose. HA!
