Well, I plan on changing the oil this week in my malibu due to some fuel dilution issues I had because if overdosing on a fuel additive. The car has almost a 117k on odometer, and burns about 1 qt every 2200 miles or so, I've had many members reccomend Maxlife, but I think I'm leaning towards Defy, but I'd love to try a full syn high milage oil, but is there such and animal?
