I do not know your bike - if it works for you- fantastic -
My not being able to find a straight answer to my oil questions for my bikes, I spoke to Pro's at Silkolene, Castrol etc as well BMW Tech. (as I have an 02' Dakar and a '04 1200 I wanted to really know my options) -
The outcome for my bikes was that the boxer engine is quite happy with either mineral, semi or full synthetic as it has a dry clutch-
However, since the Dakar has a wet one Silkolene, (who make bike-specific oils) BMW, Castrol Oils and two independant mechanics of amost 60 years combined experience on bikes have told me the same thing- that is not to use the fully synthetic one in that bike due to a very high probability of clutch slip. I am not an oil engineer so I am happy to accept that and have stayed with semi in the dakar and full synthetic in the 1200gs. We each must do our own research -

Some have said 'if it goes in' or 'if it fits then it's fine' - I do not agree with that! it may well have consequences anyone might prefer to do without. In the end- it's your bike so it's your call!

And depending on circumstances, it would be fair enough to say that some oil is better than no oil -says he- having put some semi synthetic engine oil into a Mauritanian army 4x4 front differential . It had struck a rock and cracked- and he was trying to get back from the border to NCK- I saw him the following year and he told me my 'repair' with instant metal etc had held- (good job too as he let me back in with a nice glass of mint tea and a smile!)
