Best engine oil?

[Pem Brooke]

I know this is a much discussed topic...tried searching first....
Preference on engine oil? I used Amsoil in my Firestorm in Canada but not sure if it's available here. Any suggestions for an alternative?
Cheers

I use Motul 5100 10w40, have had the bike from new with now over 80k miles on the clock, all is well.

yup I've used motul and mobil, both very good....

Silkoline super 4 here but really any good branded 10/40 semi synthetic will do.
