Reported by Arnulf Doerner.
The name of the BP filling station near Portimao has changed to RUBIS but note that it does not refill cylinders any more.
There is, however, an LPG gas filling station for cars to the west of Boliqueime that is used by caravans. There are adapters for foreign bottles available and an 11Kg bottle can be refilled in a minute. The station is to the west of Bouliqueime on the N270 that is a northern spur from the N125.
