Butane type for jet lighters ???

[Savoy]

Hi...

I'm wondering if there's a particular type.. or "better" type of fuel
for jet-torch type lighters.
Does anyone know anything about this?

I just got a new triple jet cigar lighter, and it "flames out" at anything
less than the highest flame setting... and its way to much.
It doesn't toast the foot.. it anihlates it.

Right now I'm using just some Ronson fuel that was on hand.

Is there a better/more pure fuel for the purpose?
Is it something else? Am I missing something??

Thanks in advance!
Greg
