just how low can you run a 904 or 907 and still get sufficient pressure to cook ?

Mulling what cylinders to take to spain for a couple of weeks, have a 904 with 30% left and a 907 with 50% left.

Consumption wise - there is enough given we will probably do 6-7 nights on campsites with hookup to boil water, but it occurred to me - how low can i run a 904 or 907 and have sufficient pressure for it to be usable on the cadac or cali kitchen burners ?

PS. Dizzy had a full on wash and polish today!

The pressure of the gas cylinder (for a constant temperature) will remain the same as long as there is butane in the liquid phase, and then will drop rapidly.
