My car ran out of petrol (faulty gauge) and the only spare fuel I had in the boot was a 1:50 premix for my boat’s two-stroke outboard engine.  Could I have used that to get me to the next station? Harry.

Yes. Your initial restart might take a moment longer and you might not get the sweetest smelling exhaust fumes, but the car’s four-stroke petrol engine would probably run well enough on a 1:50 mix to get you to a petrol pump, and in many engines would cause no immediate harm and not need purging.
