First post here. I sent in my oil using Caterpillar services since it was a little more convenient.
I keep extremely detailed records on fuel fill ups and ONLY fill up with Marathon (used to be Texaco) gas stations since they have the STP additives, which may have helped get decent numbers. I also put through a period of 2100 miles and 4 fill ups a 16 oz bottle of Marvel Mystery Oil.
When I bought the car over 2 years ago, I went home and changed to Rotella 5W-40...the car has had nothing else in it since.
