Mine is thirsty. Not too bad compared to many. That OCI it used oil at a rate of about 1700 miles per quart. Interval was between 179k miles and 183k miles. Initial oil was Valvoline Next Gen Maxlife High Mileage 5w-30. Topped off by a can of MOS2, the rest of the jug of Valvoline, about 5 or 6 ounces of MotorKote, and some random drippings in a bottle and a pint of Valvoline Next Gen Maxlife High Mileage 10w-40.
