Mine is on Rotella, 10W30 no less, and hasn't used any since I fixed my boo-boo on the oil filter return line.
I've seen no evidence that one oil has significantly higher inherent consumption rates than any other. Would welcome any evidence that proves me wrong, as long as it isn't opinionated anecdotes. Noack runs about the same for all of them too. Delvac is very good oil. So is Delo, Valvoline Blue, Castrol Tection or GTX diesel, Rotella, etc. Use them all with confidence.
I just learned about a new Delo coming out soon, a Delo 5W30 HDEO. Got a little excited about that and would switch over if the price is somewhere close to right. It's an oil I can use in all my cars, trucks, tractors and small engines.
