Vehicle consumes oil at high rate. Approximately 5 qts per 3000 miles driven sometimes more often. After new oil is added, acceleration will delay at times, usually when starting from a complete stop. When the vehicle begins moving forward a cloud of bluish/white exhaust will be created. The clouds of exhaust occurs more often just after an oil change or oil is added. Will continue for the first 1000 miles then will become less frequent as more oil is consumed and the amount remaining in the oil pan is lessened. Has occurred since I purchased the car.
