I'll be doing a quick oil change when I get back to the states and get my baby out of storage (95 Mark VIII base model). I'm currently running AMSOIL 100% synthetic 5W-30. I just checked the AMSOIL website and their recommendations actually include 5W-20 and their 0W-30 Signature Series. What are you high-mileage drivers using? I intend to hang on to this thing for a while and I'd love to crest 300,000 miles one day without an engine change.
