Good question. It’s true that HEET has less BTU than SLX. But the proof is in the pudding. I find only a 30 second difference of boil times (2 cups of 60F water) when comparing HEET and SLX. So for a 300 second boil vs a 330 second boil is only a 10% change. That’s in the noise of too many outside variables. So for 3 season estimate I bring 0.75 mass oz per meal of HEET or SLX (my buddies use SLX). So for a week, I’ll bring 10 mass oz or 11 mass oz. It’s really hard to notice the 10% difference. Some other benefits of HEET over SLX is it burns cleaner (less sooting), no smell, no fidget starting at 0F (or any temperature), and I get it cheaper.

Here I am talking about HEET and for the past 4 years I haven’t used HEET! I’ve been using the cheaper walmart copycat version. It is 98¢ /12fl. oz. Then, later it goes on sale for 50¢ (for about 15 seconds!)

May your stove always bloom.
