1996 Mazda Millennia V-6 mileage: 75,000. I had the 60,000 mile service performed by independent shop specializing in Japanese cars. I have had oil changed every four to five thousand miles. Valve cover gasket replaced six months ago. The car seems to use about two quarts of oil between oil changes. I had the car check by the Mazda dealer and they found no leaks and no apparent reason for oil usage. I have not noticed any blue smoke or smell from car. The dealer offers no advice. Have you any idea what is happening to the oil and should I be worried about engine damage?
We have found similar problems with other cars approximately 60,000 or more miles. Replacing the valve stem seals reduces the oil use. They are made out of rubber and over time become hard and brittle and no longer seal.
