Fred, are you saying that the current owners manual specify either either 10W40 or 20W50 is recommended? I'm almost afraid to ask (I haven't been on the forum very long, but long enough to know where this question can lead to), but is 20W50 generally considered the replacement for the unavailable 20W40?Yes, that was because at the time that manual was written Yamalube was available as 20W40.
They subsequently dropped that weight and now have either 10W40 or 20W50 only. Current FJR owners manuals specify those Yamalube oils, even though it is essentially the same identical engine as the one they previously specified 20W40.
IOW they specify that oil because that is what they sell, not because the engine particularly needs it.
Thanks.
