I am in Australia and recently bought a new 08 FZ6. After 1000kms the headache of the oil change reared it's ugly head. The manual said use 15w 40 oil. No mention of synthetic, semi synthetic, sewing machine or whatever. You can't buy 15w40 in Australia. what the f***?. I asked so called reliable sources and God forbid I then hit the internet forums.

I put in Shell Fully Synthetic 10w 40. From about engine rev 4 or 5 the engine felt and rode like sh**. I took that out and put in Motul 5100 10w 40. A big improvement. I then took that out and put in Motul 5100 10(15)w 50 oil. Now the engine feels good, smooth and rides well again.:thumbup: I offer my thoughts from a logical and hands on approach to things. I have some natural mechanical ability but no qualifications in motor mechanics at all. I hope this may help someone like me that likes to follow the rules and gets pissed off when a simple thing like changing engine oil becomes a production bigger than \"Ben Hur\".
