Oil threads are always interesting because very few people actually give a reason why they prefer one oil over another. Logically you'd only refrain from using a particular oil in favour of another if you'd experienced engine damage because the oil failed (are there other reasons?). How many people have experienced engine damage they could put down to a particular oil?
I've used Castrol GTX (a mineral oil) in my Fazer without mishap and would use it again no trouble (it is up to spec for the engine) but I now use Halfords semi-synth -because it is almost as cheap mainly, but also partly because it's fashionable - I have to admit.
I have actually experienced engine failure due to bad oil in the distant past, on my XS250 a valve seized taking out the valve gear and blew a hole in the rocker cover. The oil? that was actually Castrol GTX in fact, but the XS was a hack and the oil hadn't been changed for at least 20,000 miles. I think that illustrates the greater importance of regular changes, I don't think the brand or type of oil (synth, semi or mineral) is really an issue as long as it has the right spec.
