    Rated 5 out of 5 by from As good as it gets I run a Bandit 1250 SA K8 and have just started using this FULLY synthetic Castrol oil. NO, I repeat NO clutch slippage, which some people have said they get using fully synth. This oil is designed for motorcycles. I think those getting clutch slippage are using car oil, NOT bike oil. Anyway, as for the oil itself I have noticed a smoother running engine, from first run out. Smoother gear changes, especially first gear. The whole engine seems to pick up and run smoother. I was using the part synthetic Castrol 10w/40 before, so I can give you a direct comparison. This is the oil to go for, without a doubt !!! I am so impressed with this oil I bought another tub for a future oil change. Good pricing from Halfords
