We’re tackling many heavily debated subjects about motor oil in this video and learning how specially formulated motor oil can help new and old engines add more miles to the odometer! Can you use synthetic motor oil in old cars? Can synthetic oils cause leaks in old cars and engines? Where did the idea originate that synthetic oils are not compatible with old engines? If your car is consuming a lot of oil, should you use a thicker oil grade? Finally, when should you use a high mileage oil? I spent time discussing these questions and more with Mobil 1 engineers. Watch for all the details!
