I have the 3126-E Cat engine which is the same block as the C7 with the shallow 19 quart pan. I change the oil once a year and it is about one quart low. I average about six thousand miles per year.

Last year I done a lot of mountain climbing and that is probably where it will use the oil because when I was cruising in the flat states of Iowa it did not strain the engine at all. It was all cruising. So it does make a difference on the terrain you are pulling.
