Not sure about putting any fuel on the catalyst as it is supposed to kill it. Not advised in the instructions in the peacock along with using an overly hot (blue) flame which will also kill the catalyst.
I've had both my peacock warmers on the same catalyst for about four years now... Only changed them once so far in 6 - 7 years of using them. They get used 5 days out of 7 all day when I am out surveying in winter.
They light first time everytime even if they have spent the night unlit sat on the dashboard of the van at minus whatever it may have been.
I believe the Peacock ones are the originals which have led to various others being made including Zippo, Whitby and the cheaper chinese copies.
