I nursed my way through the first tank on smaller limbs, nothing more than 8" diameter or so. Then, I put the 25" bar on and got into bucking the big stem pieces of some red oaks for the rest of the day. Used up 4 tanks of gas this afternoon, and made quite the pile of sawdust. Man, this has been a revelation!
I love my 036, 360's, there my go to saw, run 18" 3/8 on them in aussie hardwoods, but if the 362 was a revelation to you, just wait till you run a 661
