For all Spyder engines Valvoline 4 T ( stroke ) full synthetic for Motorcycles 10/40 very low Molybdenum ( moly is bad for wet clutches ).....Walmart sells six-packs for $ 6.35 or so per Qt........Get your filters from BAJARON........Mike :thumbup:
Having the 2009 and I asked and checked on the same thing but in the end I get the oil filter gaskets from bajaron you'll get it faster then you think and to answer a question if the oil matters YES! I do race mine often and the amsoil seems to help with clutch more then I can say.
+1^^I am happy with Amsoil..
But why not like Castrol or Mobil 1? I heard a lot stuff about slippery clutch...very worried about that. I really want the best for my bike...:dontknow:
I know for sure Amsoil is best but anything else that's a runner up?
The main thing is that it's an oil specifically designed for motorcycles. Car oils have additives in them that can adversely affect motorcycle clutches and make them slip. Motorcycle oils use different additives that don't affect the clutch.
Most modern motorcycles (Spyders included) have a 'wet clutch' - i.e. where the clutch is immersed in engine oil. Normally the same engine oil circulates around the engine, clutch and gearbox.
Most cars have a dry clutch. As the name suggests it has no oil or any other liquid in the clutch casing, the clutch is effectively in air. Cars also normally have engine oil just for the engine, a dry clutch and then different oil in the gearbox.
The advantage of a wet clutch is that its smoother and performs better but is also more complex needing multiple plates etc.
Normal car engine oils have additives designed to reduce friction between surfaces which are really good for your engine but terrible for your clutch - hence why you must use motorcycle specific oils.
