Put some "FANGS" on the beast!

X2. With my stuff it really depends on the wood. I've cut 3 cords of silver maple which was probably 10-12 tanks of fuel in the 460 without touching the chain and the half cord of mulberry I cut the other night took out two chains on less than two tanks.

I think that's the answer. I'm cutting mostly Oak and Ash these days, and it's hard on chains. I'm guessing the guys claiming they go days without sharpening are mostly cutting softwoods. Someone even mentioned WD-40 on the bar to avoid "gumming". What the hell? Must be cutting pine trees!

yikes - I sharpen mine with every tank of fuel - quick touch up with my files in the field. After 6-8 tanks, I'll pull out the dremel if anything needs reshaped. I could not imagine going 6 tanks without changing or touching the chain.

It depends on the saw too. The way a MS460, MS660, or similar drinks fuel, it ain't hard to go 5-6 tanks in big wood, even Oak, without touching the chain.
