Hi all,
We are coming over for the whole of September and are looking for advice on gas bottles:

When my father last came back from Spain he brought two silver gas bottles with him. In the area we are, we have only seen the red Repsol bottles. The regulator is interchangeable so we are wondering, if we bring the bottles with us, will we be able to get them exchanged for red ones or get them easily exchanged for full ones?

He assures me that where he stays (valencia), they can be exchanged at petrol stations and other places  but since we have only seen the red ones we are not sure of the situation where we are (Gandesa / mora d'Ebre areas). Can anyone advise?

Many thanks,
John.
