2006 Mazda Tribute Question: oil loss, replace 2 qts every 3 months. no leakage or signs of burning
Answer #1patrick mannion from Greg Solow's Engine Room, September 01, 2011, 19:09Master
A cylinder leakage test may show leakage past cylinder rings. If the engine isn't leaking it the oil must be being burned or consumed in the engine. How many miles are on the engine and how many miles do you typically drive in two months. Perhaps check the PCV valve to see the engine is "breathing" properly.
