PS If you are really stuck or worried. Drop me a PM. I will leave a bottle of the stuff by my front door. Have it with my compliments.
In fact that's a good idea. Ride over, heating the engine up. Put on centre stand, nice and level, outside my humble gaffe in E1. Wait four or five minutes for oil to settle. View sight screen. Top-up (if necessary) with FREE oil. Ride away.
