Hey oil gurus! Disclaimer: my first TDI, my first EGR equipped vehicle, not my first diesel. As you see in the picture that is oil color after 100 miles, yes one hundred miles driven on it. New to me 05 Passat TDI with 190k miles. I have receipts and car fax confirmation that vehicle has been serviced 7k-8k miles at the shop that out Pentosyne oil and OEM filters. Vehicle does not smoke, no blow by, turbo solid. I changed oil with Rotella T6 15-40. And drove total of 100 miles, 50 of it freeway speeds. And that the color of my oil. I'm comparing it to my 01 Cummins with 110k miles. On Cummins I get that color after maybe 2k miles. Is TDI run different? Is that because of EGR stuff? Or is it because different oil is now "cleaning" things inside?
