rancid?

I found Perma Fluid, in a petrol lighter refill tin, at a local convenience store. It's by Ronson. But the Restoration Hardware hardwarmer refuses to light. The fuel stinks! Bad. Really bad. Can lighter fluid go rancid?!

I was told once, by MEC staff no less, to throw out my "old" camping white fuel: it was rancid.

There's printing on the bottom of the 100mL container: 08.08.03. So then it's either 3 years old or 8 years old!

Poured some on the ground and lit it. It worked.

That was not a very conclusive test...
