Car has 11k miles. JMS Boostmax Tune, CAI, and cold side bov. Car misfires at start up until given a little bit of throttle, then the idle goes normal. and every so often on start ups, clouds of white smoke. only lasts for like 20 seconds. Oil changed every 4k miles. most recent being like 3k miles ago. Usually check oil quite often. But when car started acting up. i checked it, and was very very low on the dip stick, and was black. Anyone have any idea what might have caused this and at such low mileage? What could cause the engine to burn this much oil ? and would it correlate at all to a cylinder misfire? Thanks
