I think the oil is the same grade (10w40) across all B&D series engines so yes you can use that, oil filters are the same for pretty much all petrol engine Hondas, plugs you'll need to make sure you get the right ones for your engine, not sure if they're different. Magnecore leads are expensive so if you don't fancy those prices there are cheaper alternatives, I've seen a couple of guys on here get them recently but I can't remember who it was. Larkspeed have good prices on plugs and leads and I got my oil and filter from Opie on here.
