I have had great success with these products in both Honda and Mercedes cars; even using the new stuff (I use exclusively 15W-50 year-round in my gas cars)I've noticed no deposit accumulation. Zero.

I have such confidence in Mobil synthetics that I just bought 2 cases of Delvac 1 (it was a B$%#h to track down) for my soon-to-be-delivered '92 300D.

Stay on Mobil-I've got to figure they'd be interested in your unique-seeming situation. Good luck!
