Bit odd there pal. Im in Gladstone and run 10w-40 just fine though
Surely you would notice that much oil being burnt by the engine - evidenced by the cloud of smoke you would be leaving behind. Is it smoky on start up or after a long idle?
If not id definitely be doing a thorough inspection around the bike, though again with that much fluid you would likely find a puddle anywhere you park.
As stated it shouldnt be in that state after a mere 25k kms...
