So I've run out of spare oil for my 2010 GSA, and after having bought Putoline from the dealers last time (on their recomendation), I thought I'd give castrol a try to see if it lasts longer as mine seems to use a lot of oil. The putoline the dealer recommended is 20w50 Semi Synthetic, but the 20w50 Castrol (act evo 4T) is mineral. Which do I go for I thought? So I checked to see what Opie Oils recommends for my bike; 15W50 Fully Synthetic

Ok, so what does Castrol recommend I thought? Power 1 Racing 4T 10W-50 Semi synthetic
(http://www.castrolmoto.com/en/oil_selector.php) What makes my head spin even more is that when you search through the Castrol oils on their site they don't do a 10w50 Semi synthetic, it's either a 15w50, or 10w40 





So the question is am I better to stick with the 20w50 and not be fussed it it's Semi Synthetic or mineral, or stick with semi synthetic and go for 15w50 or 10w40? The handbook says 20w50 though
