"Normal" Oil Usage
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 c...

Yes, there are two different pans on the C7 shallow and deep. A call to Caterpillar with the engine serial number will remove any doubt about the oil capacity of YOUR engine.
While use of the exhaust brake may slightly increase oil consumption (remember, they work by generating back pressure-- in the range of 55 PSI), it is a no-brainer-- use it.
BTW, a quart/800-1000 miles is very reasonable on any diesel engine.

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.
