BMW has a bulletin out which states to use 10W50 mineral oil during break-in, 10W40 or 50 from 600mi to 6K mi mineral, and continue after 6K with mineral or go to BMW recommended synthetic 10W40 (07 51 0 406 629) or BMW synthetic 15W50 (07 51 0 394 083). These BMW synthetics are a different part number from the synthetic BMW oil that the motorcycle side of the business. I wonder if these are the oils made by Castrol since BMW (cars) has a deal with them.
The bulletin also states that this info SUPERCEEDS any previous info in the owner' s manual or repair manuals, etc.
Recomended Oil for The K1200S is:
CASTROL GPS4T 10/40W
