Just as I promised here are my TDI results using Schaeffer's 7000 15w-40. This vehicle is a daily driver (2500 miles a month) used for 90% highway at or over the posted speed limit of 70 mph. OEM filters. Only modification is to the EGR duty cycle. No make-up oil. No oil additives. Schaeffer's Soy Shield diesel treatment at a 1 oz per 3 gallons ratio.
