40576 Safeguard Ethanol Fuel Conditioner-473ml

Q: Is this okay for a carburettor engine

I'm using it in a 4 stroke petrol lawnmower. and to protect the fuel system of a seldom-used emergency generator. Seems OK - the reason I bought it was to stop the Carburettor from gumming up, and to extend the storage life of the new high ethanol fuels, E10. Quite happy so far no probs after 3 months of use.

Q: Been using lead replacement so far on my 50 year old car, Is this designed to be used together with a lead replacement, or as an alternative?

It's to aid the difference between the old E5 petrol to the new E10 that most garages sell as unleaded. ( If you open a carpetrol filler flap pre 2020 it will probably say use E5 95ron ) I would assume you would have to use both the lead and ethanol replacement but a mechanic that deals with vintage ( lead based petrol) vehicles, would be more an expert and you would be advised to ask them about that.

Q: Can I use this in a 2016 ford fiesta 1.2 which has a catalytic converter without harming the Cat

Answering another question in this list, the manufacturer states that the product will not damage a catalytic converter. Some other customers have also said the same. That's all I have to go on.
