Hey guys,
New to motorcycle servicing, I checked out the cost of Motorcycle oil & was surprised how much more it costs than normal car oil

.
Jumping online I did a search to find what others use & what might be better value for money, I came across various threads from riders who use Diesel oil & swear by it.. 1x in particular being Shell Rotella T 15w40.
Unfortunately this oil is only available in the USA

, and so far, all my hits have come up with USA riders using generally USA available products.
So.. just wondering, what do you Aussie riders use in your steed ?
My ride is a 08' GS500 & apparently it's recommended I use 10w40 (but 15w40 seems good too). Has anyone used 5w40? is there pros/cons to using a low viscosity in your bike than recommended.. especially in summer ?
Also, where do you guys buy your filters from ?
regards,
