Consumer Description
Excessive oil consumption. I bought this vehicle new from a Mazda dealership, with factory warranty. The check engine oil light came on at approximately 6800 miles, 3750 miles after the first oil change. An additional quart of oil was added. I brought it back to Mazda to confirm no oil leaks, which they confirmed. They were made aware of the Mazda service bulletin for excessive oil consumption, which they acknowledged, but indicated they will monitor as there is no solution from the factory.
