600,000 miles
check out this link, this is for the ford and dodge guys who think the duramax is not as durable as your beloved cummins and powstrokes. http://chevy200k.com/gallery/detail.php?id=8ec58282
We have two freight companies in my family. Currently there are six DMax's with over 300K and three with over 400K. Let me also add that we have several PSD's and CTD's that have high mileage too.
You just said the words right there MAINTAIN. Yes it does pay off, that is why even thought I know it is probably overkill from hell, I change my oil every 5k even though I am running Amsoil. I just believe in taking care of what I have. I even do the same in my tillers, tractor and mowers and not a problem yet.
Glad to see I am not the only one, fuel filter gets changed the same and washing is the same. Buddies say I keep it too clean.
