To follow up to my original post, I had the oil changed but the shop over filled it, putting in 7 gallons. I drained one gallon off, which left the oil dip stick showing about half way between low and full. We then drove 1300 miles during which the engine threw out almost no oil. It did use a little more than a quart. So, I've learned not to fill it up when changing or adding oil. My 6v92t takes about 6 1/2 gallons to reach the top mark on the dip stick but 6 gallons is what is really needed so as not to over fill. Thanks Gurus for the tip.
