Everyone always says their idi drinks rotella .. I don't know why. I have had nothing but good results using rotella. I highly prefer it over delo. None of the 6.9 and 7.3's I've had drank rotella. My current truck has 245k on it and doesn't drink it at all. The only oil I lose is from a leak at the pressure sender. I briefly switched to delo on my last truck and it felt like it was dragging it down. It also leaked at the oil pan which it didn't with rotella. I immediately switched back to rotella and it stopped leaking and it no longer felt sluggish.
I know that sounds weird since delo is suppose to be thicker. Just my personal experience with the two. My absolute favorite oil is Royal Purpal. But who can afford that stuff in a diesel ... not me lol.
