Hopefully I posted this in the right section. My uncle has a Baja Mini Bike (I think a 2008) and has always has QSGB 5w30 once per year, since it is not ridden much. Is this the best oil for the bike or would something be better? The model is either a Baja Mini Baja, or Baja MB200, both have the same 196c motor and hold appx. 3/4 qt. of oil to fill it up. TIA
