make sure you put the right oil in your truck!
Did an oil change last weekend and decided to use10w40 instead of 15w40. Just to thin it down some for the colder temps. I was going to go with 5w40 synthetic but at the time it seemed a little pricey. Anyway about 2 days later my oil pressure gauge drops down to nothing while it was warming...- Superduty78
