hi recently brought a 15hp efi 4 motor an was wondering what grade engine oil is being used in the engine from new.
here in Australia two grades of oil are listed for use in the engine being a 10/30 weight and a 25/40 weight.
what gives oh and yes i know its somewhat related to temp/climate that the engine operates in.
