Hi, there is no information on the oil change service interval or the grade of oil to be used in  Bosch professional pressure washer range, such as GHP 5-13C.Nor am I able to find the drain plug in the parts diagram

Hello aim120
If you can't find the drain plug in the appropriate place (under the crank/piston/pump housing) then it likely doesn't have one. If and when you drain the oil, remove the dip-stick and drain through there.
Generally the advice is to use a non-detergent motor oil or a proper pressure washer pump oil for pressure washers, whatever brand. If Bosch don't recomend a specific lubricant in their literature, then I'd go with that.
