The only bad thing about my VW diesel(beside dieselgate) , is that it requires a synthetic oil that's pretty expensive. And it called for oil change intervals of 10,000 miles. I've never been a fan of oil change intervals that are that extended and I am certainly not a fan of expensive synthetic oil. But because of that expense I decided to use Blackstone lab's oil analysis reports to ensure that these extended intervals actually were valid. 

After the free oil changes up to 36K miles, I changed the oil at 10,000 miles and sent a sample. Oil was absolutely great and still within spec. Next oil change I want to 11K and still within spec. And so on our way up to 13,000 miles. Oil was still completely 100% within spec and no metals that would indicate excessive wear. I stopped there but I could probably could change at 15K. 

So I do believe in those 10,000 mile intervals with synthetic oil for that engine. I'll be glad to post the reports if anyone's interested. 

However.... 

I did it for my Ford power stroke 6.0 L engine too. The shear properties of synthetic oil begin to degrade at 10k miles. So I use regular Dino oil and change every 3000 miles on that one. 

Hope this helps,
