Oil advice - Hayabusa
Just wondering what oil people are using in their hayabusa engines??
Its the first time i've had to change the oil so not sure what to use. I believe it should be 10w40 but do I use synthetic or not as I have read
some threads about it not being good for the clutch?? slipping etc??
Car will be used for trackdays....any advice appreciated.

For performance bikes, I was always recommended to use a good semi- or fully synthetic oil. Mineral oil was touted as causing clutch slip.

I've been using Silkolene Super 4 10w40 - this stuff:

my main use is trackdays also, no real problems (that were caused by the oil anyway!)

Another vote for Castrol Power 1 (used to be called GPS) in the correct viscosity. It's a semi synth but some of the fully synths I have seen
like silkolene are so thin even when cold they are like water which worries me when it comes to surge. Andy Bates also used to recommend this one but
I don't know if its still his current recommend.
In some ways I'd rather go for a mid range semi synth that is just over half the price of a fancy synth and change it more often.

MK quote 3,000 miles between oil changes, but if you're 'giving it beans' on a regular basis, then factor that in accordingly.
I've just changed my oil after the car (and engine's) first 1,000 miles, due to a leaking oil-cooler hose. (took the opportunity to do so
whilst the cooler hoses were off). Clear as a bell, with no residue or signs of contamination. Used 10/40 semi-synth as recommeded by most Busa BEC
owners and by the Suzuki dealer here.

hi all i have been a bike mechanic working on some top race bikes and we only use a 10w40 semi oil any top brand will do if you go fully we found it
would leak though any week point and there are some clutches that dont like it the only good point is you can go flat out from almost cold
as to how many miles just keep an eye on the oil when its had enough it goes black but as a guide i would advise 2-4k onthe road or 2-3 track days
but remember 5lt oil costs £28 an engine costs thousands

Very true. I completely understand the need to keep on top of oil servicing.
Ended up going for a castrol 10/40w semi.
Thanks for the advice everyone.

Good choice. If you become tempted to go fully synth my advice is research moly content first - I had to switch away from motul 300v due to bad clutch
slip with it - although I preventively changed bits in the clutch at the time, changing to a low moly content oil fixed it - the majority of the
silkolene oils have no moly and a higher Jaso compliance, so I think it's a much better make of oil.
