This topic has probably been on here several times but I am new. Manual says yamalube 0-30, quite sure it is not synthetic. Wondered if castrol 0-30 synthetic would be a better oil for this application, says on the container it flows better than any oil at low temps, anyone using it? I see lots are using amsoil, that stuff is rich mans oil around here. Have heard mention of mobil 1 0-30 but haven't seen that around here anywhere. Anyone know who makes yamahas oil? Thanks for the replys.
