I have a Cat C7. How much oil should it use in a year? Should I never add oil between the yearly changes or is it normal to add oil? When should I worry?
I just had to add 2 quarts - the last oil change was June 2013. I have never had to add oil before.

I run my 300HP Cat 2001 Tradewinds 2 quarts low. If I fill it to the full line on the dipstick it quickly blows out or burns or whatever two quarts. I go 11000miles between changes and rarely add oil. 125000 miles.

Fill them out and they will blow out about 2 qts the first day, and level off at 2 qts low. So I also have always ran at 2 qts low, and it seems to stay right there. Have noticed that when it starts using oil, that it is a indicator of the need for a oil change. Can't comment on Cats, cause I have never driven on on a regular basis.

I have a 2005 Fleetwood Excursion with a C7. That engine used at least two if not three different oil pans. If there was lots of clearance under it, I believe they installed a 23 quart oil pan. Mine has the shallow oil pan and only uses 19 quarts. When I climbed under mine, either the oil pan had a sticker on it saying the capacity or it had a P/N and I called Cat. If you put in too much oil for the oil pan, you're going to "use" a lot more blowing it out the breather.
The engine will "use" some of it in the vapor it puts out through the breather tube. I've been told it will "use" more oil with extensive use of the engine brake. I've noticed more oil residue on the front of my Jeep when in the mountains in western Canada.
Brett Wolfe - what is your take on what I've been told?
Between my yearly oil changes, 6 - 8,000 miles, I been using 2 - 3 quarts.
Crawl underneath it and see if the oil pan has a sticker on it, then call Cat.
