just wondering what you guys would run for oci's in a turbo application?

Nope.
Just buy on sale/rebate oils - last month synpower was $.99/qt after rebate.
The real trick is to run your oil of choice to the miles you think is correct then do a uoa to check how the oil is holding up.That is how the big boys do it .Quote:

On forced induction cars I like to use hours on engine run time versus miles. One set of miles can be very different from another. Less so with hours of engine run time. I use hours only for the GTO OCI's....Quote:

5K synthetic oil change a waste of money?

What does Mazda recommend for your car?
Best is to do somewhat short changes (maybe the severe service recommendation?) until the break in is complete (check the site for other UOAs to see if you can figure it out) then do a UOA after a 5k run. That'll tell you if it's a waste for your car or not.
Over the road diesels are not relevant to passenger cars. They've got huge sumps, multiple filters, bypass filters, etc. Different engines, different applications, different requirements. Just different.
I've got a turbo car and do 5k OCIs with synthetic. I've also done a few UOAs. Search my name and Saab and you'll find them.
So unlike some others here I'm semi-qualified (ok maybe barely qualified) to comment, and I have a vested interest in knowing the right answer - for my car.
The answer to your question is, not necessarily. For some cars 5k is probably all you should go. That's what I've found so far with my Saab. The TBN takes a beating and shearing is kicking in at 5k. Fuel dilution doesn't help and the car is a documented sludger. TBN is still in the ok range but I like to stay on the safe side
