How thirsty is your saw?

Can't say I've really paid much attention to fuel consumption. I can get quite a bit of cutting with my muff modded 066 on a tank. Can get quite a bit of milling done with the 3120 before the tank runs out, but it has a pretty big tank.

The Homies run a long time on their teeny tanks, and I really haven't used the 372 for long enough stretches to really tell yet.

I am surprised nobody mentioned sprocket size.
I have noticed a big change in fuel consumption when changing to a smaller sprocket fuel consumption going up. If your saw can handle the higher chain speed and still have enough power go with a bigger sprocket for better fuel efficiency.
 
My 394 likes to drink up the fuel in a hurry as well. Never paid much attention though. My 345-e on the other hand, I can cut forever and a eternity on 1 tank of gas.

I get about 20 min of WOT throttle out of my 660 with the 36 buried in cottonwood, that would be a stretch though. Thankfully it has a clear tank so that I can keep an eyeball on it, miserable to restart after it is ran out.
 
Last time I ran the 088 in a 40"+ downed Oak I bucked it in to some 24" slabs. I had the 41" bar w/full comp chisel buried all the way and had to go around to finish up the back side on the first few. If I remember, it was 7 or 8 cuts. I was kind of surprised how little fuel it used. Over a quarter, but less than half a tank. However, it is a fairly big tank.

I guess I should say that I don't run it all the way dry. During the cut, I can hear it as it starts to go empty and run lean for a split second. I go ahead and shut it off then. No problems restarting it that way either.
 
Sounds a bit thirstier than my 395. It's largely a function of time, so my question is how sharp is the chain?

Really sharp chains cut alot more wood per tank.

My thirstiest saw is my 880, but like Andy says it takes gas to make power. Seems especially with the 880, the harder you lean on it the more gas it sucks.

according to acres site, the 394xp has only a 30oz tank, the 395 was quoted earlier to have a 34oz tank, about 12% less, similar to going from 8-9 cuts to about 7-8 cuts.

by comparision, the 051/076 have 41oz tanks, the 660 has 28oz and the 880 has a 44oz tank, using 29.6 ml/oz for the amercian ounce.

How about twin 3120s on an 84 inch bar? Cutting a 56 inch diameter stick?

That's got to be thirsty!

(That's him, not me. I've never even seen two powerheads on the same bar in person.)

I couldnt tell ya how much fuel my saws use, they cut, they use fuel and bar oil. Two gallons of gas lasts me quite a while, definitely not enough to really care about. Now, if you guys ride snowmobiles, you know bad gas mileage. I've got a Ski Doo REV 800, thats the toy that takes the cake, by far!
