Sounds like a good call. I'm a little over a year into owning an older turbo diesel MB and love it. Most of the work I've done on it is quite straightforward--- a welcome relief from near total dependence on repair shops. Fun to own and drive too. Although KY winters are mild compared to yours, I'm certain that bio is still an option in winter. Last winter I never ran less than 70% bio and added an anti -gel to the tank and did fine. Seems that the anti -gel (Diesel Kleen) doesn't work on B100 but will do OK with a blend.
