Which liquid is found in most cigarette lighters?

I remember when it was lighter fluid.

Gary, Lighter fluid is for Zippo lighters (some fools use them on barbecues!), butane for gas lighters and camping stoves.

K O T K, I like this.

Frugal Fred, Zippos still use a variant of diesel.

Why are they exclusively manufactured in South Korea?

Gary, Me too,,hated the smell of lighter fluid and I am glad it is not gasoline,,” 💥 BOOM

I have had lighters that used petrol.

Apparently, almost half the Teenage population of London," that's in England" spend at least one year of their lives inhaling Butane . Its a sad fact . I read that in a medical Journal " the Lancet "medical magazine.
