Hi bigprop I was aware of the 15 /50 but in our climate is that OK? I have looked on opie oils that have a good selection of oils may go motul 7100 or castrol power 1 racing. FTL40 it may be a bit cold here for 20w/50 thanks for your input the only way I can get mobil fully sync 10w/40 here is shipped from the states so a no go
