i heard for conventional motors,im not applying to race motors or power adder motors.. that during cold winter seasons u should use light weight oil like 5w30 cause its doesnt get as thiick as say 20w50 under very cold conditions.and to use higher viscosity oil during the summer time or hot condition areas
