We have a 2004 Kountry Star with the Cat 330 engine. We recently returned from a 2500 mile trip. The oil level is now at the add mark. Would the add to full be 2 Quarts or should I add a quart at a time to see how much it rises on the dipstick. Also for this mileage would this be considered an average/normal consumption. Most days I drove 60 to 65 MPH. The motorhome has 44,000 miles. I'm running Rotella 15W-40.
