BUT Motorcycle oils have different needs to cover and therefore not recommendable for cars in general. For example there are additives to prevent clutch slipping as it runs in the same oil. Further middle piston speed (correct term in english?) is almost double. Pressure due the gears is very high, as transmission is in the same oil too (need for high shear stability). For this reason there is a present standard called JASO MA for bike oils...
