The butane my Dupont lighter user manual recommends
Expensive but sure works well in my Dupont Defi Extreme lighter. I originally used the black canister Dupont butane which worked fine in 'normal' temperature conditions but would never light reliably nor maintain a consistent flame height when it got cold.<br /><br />Dupont's red canister fuel solved those issues. P.S. It's -15° F today and the lighter lit my morning cigar on the first strike!
