I used Castrol Magnatec once and remember the bike absolutely hating it, so i had to get it changed.
It may have even caused the clutch to slip as well.
The thing is, if they say certain oil is designed for bikes then just buy bike oil, it's your engine you're playing about with here, is it really worth risking anything over a couple of quid?
+1 for the semi synthetic too.
I remember now as well, the bike took much longer to warm up in winter when i had the Magnatec in, but once i changed it everything went back to normal.
