Katina Renee @jayeff has given you what you need for the lights and some sound advice as far as the oil consumption goes but there is one thing you can try to stop the problem . If the motor is a 2.5 litre make sure your using the proper oil . It calls for 10w30 oil and if you use 5w30 or other lighter grades you will use a lot as it will actually run through the valve guides . This motor is terrible for this but simply using the proper grade oil should fix the problem . One last thing you should change the oil and filter every 3500mile or 6000km if you want to enjoy your car for a long time , failure to change the oil on a regular schedule is a death sentence for the engine. Hope this helps
