Greetings-
I allowed the car to go past a reasonable breaking in period and out of warranty before switching to the slightly heavier Mobil 1 ESP 5w40. Maybe I am old fashioned, but I prefer the 40 weight in diesels. I have owned 3 VW Rabbit Diesels ('78, '80, '81) and a 1980 240D. I know this car is light years different, but old habits are hard to break! Anyhow, I drive about 75% highway and use Power Service additive. Oil and fuel filter changes every 10k so far, but I think I will be shortening the interval after this oil report. I am not happy at all with the TBN. It looks like this oil was spent. I am thinking 7500 miles is a reasonable next step. Thoughts? TIA~
