Looking for an opinion on viscosity.
I have the FJ1100 air cooled.
Last week when we hit 32 deg. I was DT and when I leave the lights the oil light comes on. It's just a level indicator, so you know what's happening.
In the earlier years I had the same bike that did the same thing, so I went up to 20-50 and that solved the problem, but I had clutch drag when cold and could feel the engine labour until the oil got up to temp.
I wanted to put the Rotella synthetic 5-40 in but fear that I'll be seeing the oil light more often. There is the conventional Rotella that is 15-40, which is closer to the viscosity that the Manf. recommends, 20-40.
Question:
Should I just go with 20-50 Mobil 1 synthetic (or Amsoil) for V-twins which is 20-50 or Rotella 15-40 which is non-synthetic? Is 20-50 too thick and 5-40 too thin? I think Yamalube is available in 20-40, but I don't want that stuff, I don't know any ting about it.
Cost - Rotella - $20 /4L
Amsoil - $80 /4L
Mobil - $56 /4L
Didn't really find an answer on Bob's The Oil Guy.
Thanks Guys.
