Mobil 1
I have an 03, V6 with 54,000 miles. Last oil change I went with synthetic oil to see if I get better gas mileage, I used Mobil 1 5w-30. I notice when I first start the vehicle after it has been sitting overnight, that I get a slight rattle from the valves for a couple of seconds. Just until the oil gets up to pressure. Has anyone else noticed this? Any thoughts, should I be concerned.
