Hat oil do you use in your Duramax, how many miles are on it and what year is it?

On my 2003 GMC D-Max I use Delo 400 15-40wt, change at 3000 miles.
It has 82k now and was used for towing my toyhauler with RZR and two Sportsmans across the bed. No toyhauler now but it still has the Sportsmans to play with.
Our new to us 2007 Jayco Seneca 34SS with the D-Max will get the same treatment, it only has 13,500 miles and is not even broken in yet.
