Looking for opinions on using a 0w-40 diesel oil in a 2011 duramax. I have an endless supply of Petro Canada Duron E 0w-40 oil and wondering if there would be any issues in using it. You read so much about 15w-40 and 5w-40 use in diesels, but people tend to shy away from 0w-40. Is this a engine...

Drove home a brand new GP, wondering the opinion of this board the best all around oil. I was thinking I would do a couple a short duration changes, and next spring maybe go to a synthetic, although I haven't ruled out conventional!
