How many miles since your last oil change. You mention a date, but not how many miles you have driven.
By far, the #1 cause of oil "consumption" is overfilling the crankcase.
Your chassis maker, not engine maker fit the dipstick. Do not assume it is necessarily accurate. It would not hurt to CALIBRATE IT-- free at your next oil change.
Also, have you confirmed the correct oil quantity with Caterpillar-- give them a call with your engine serial number: 877 777-3126.
Lastly, with any diesel engine, do not add oil until the oil level gets to the ADD mark (yes, on a calibrated dip stick).
I know this sounds complicated, but with engine maker doing some things and chassis maker doing others (like the oil dip stick) that is how it is.
