So, long story short, I couldn't find the manual to my 2013 R1200RT so I downloaded a new one from the BMW site. My old manual had a range of oil weights and recommended temperatures on it before. Now it just says 15W-50. I've been using Castrol Power 1 10W40 for 98,000 miles on this bike and nothing has gone wrong (after all, it used to be in the old manual chart as acceptable for anything > 14 degrees F).
Does this mean I should change to the heavier weight? My bike still runs like a top. I could just as easily order the 10W50 which would up the weight a little bit at temp, since the manual seems to imply it.
Let's leave brands out of this. Just speculating about the BMW recommended weight. I find it strange that they recommend 15W anything for all bikes now when in the old manual is said 15W40+ was only for 32 degrees F and up.
