I have a bunch of leftover quarts of 80-90 GL-5 gear oil, from when it was on sale and I rode a BMW. I've been using it in my FJR for the last 40K miles. It just struck me that this might not be the exact spec of gear oil for the FJR. Is my FD now going to suffer Acquired Imploding Drive Syndrome? Like, is this contagious? I mean, the bottles are even BMW brand!
