Oh christ, he asked the oil question....
Welcome Chris
Oil is a much discussed topic - some (the misguided fools )will say you must buy bike specific oil such as Motul 7100 or similar, while others will say that if Mr Yamaha states CF or SL spec (which he does, for an FZS600) then any that meets that spec is champion. I'll leave you to work out which camp I fall into .
Filter wise, I've always used generic from my local bike shop, never had any bother.
OK, i know this is a touchy subject but i cant help giving my opinion
,
where does Mr Yamaha state
CF or SL for the FZS600?
the owners manaul and the service manual state that
do not use CD or Higher ....... but does
also say in the specs that SE,SF,SG or higher may be used.
using that info would suggest that an oil that was
only SL spec would be fine,
the problem with most of the cheap SL oils that people seem to think are fine for a bike also meet the spec
CF !!!! CF spec oils
do contain "slippery modifiers" such as molybdenum which are not good for wet clutches and not great for the high temps of gearboxes.
the asda oil material safety data sheet is here
its only my opinion but 10 years ago i would have agreed that oil was oil and been done with it, but new modern cheap oils that are designed to meet as many modern petrol
and diesel combustion only all have some form of additives.
you wouldnt catch a cager putting gearbox oil into the engine, nor putting engine oil into the gear box, so why would i put anything other than a motorcycle oil into my bike?
I do agree that if you can find an oil that only states SE, SF, SG regardless of whether it states for motorcycle use or not, that it would be fine.
but i do not accept that CD,CE,CF is of any use.
sorry guys its only silkolene or such for me.
