Oil consumption with 6.6 turbo Duramax??

Hey folks -- I have a 2012 Chevey 2500HD w/the 6.6 Duramax. I seem to be having trouble with the engine using oil bewteen changes. I've been using Shell Rotella-T 15-40W and just did my 3rd oil change at 18K miles. Seems that when I dumped the used oil back in the containers, I only had enough to equal about 8 Qts. The engine hold 10 Qts so you can see my concern. THere are NO other problems and I don't run the truck hard except to ocassionaly stand on it for a few seconds to "Blow it out" from about 25 up to 65 or so. BTW -- I'm and old Chevy small block racer from the 60's and 70's so I have some experince. Any reports of the Duramax NOT liking Rotella-T??
  • Thanks BeerCan --- I gave the filter some concideration , but that still leaves 1-1.5 Qts remaining in the engine or being consummed. I let the oil drain for almost 10 minutes when changing. I'll keep a close eye on it weekely from here on. Thanks again. --
  • Not a good way to measure IMO. The oil filter element is going to contain oil and also some engines do not drain every bit of oil they contain. Best to check the oil fill stick every week and see what it is reporting to you. Duramax and Rotella should = :)
