I believe the zinc and phosphorous ppm is limited to the same number for both oils- but I can't be sure as I have not been able to find that info for D1.
All they told me was that D1 is approved by all the big diesel mfrs, and TDT is not- so she eluded to the D1 being a heavier duty oil. It was a pretty worthless conversation to be honest with you.
The D1 seemed to make a huge difference in the way my 2.0t GTI motor FEELS- but I could just be imagining things.

Here's their online distributor finder- most of their distributors don't require a commercial account with them. Check the box "Commercial Vehicle Lubes"

I paid around $150 for 4 gallons- which works out to be under $10 a quart.
Here's the address for Jankovich-
