Chainsaw fuel consumption

This saw is a couple years old It's a Poulan Pro PP4620avx, anyways the video is mainly about fuel consumption and is in response to a question that I had from another guy. I consider this chainsaw fairly typical simply because all chainsaws are 2 stroke based pieces of equipment and the most efficient ones really only have a 20% edge in efficiency. So the log that I had cut through is also fairly typical wood where I live, Douglas Fir with this blow down being about 6 1/2 inches in diameter on average which translates into 33 square inches of wood per cut. The saw holds 500ml of fuel/oil mix and is capable of doing about 200 of these cuts which would equal 200 X 33 square inches = 6,600 square inches per tank of fuel. This information is usefull in that if a guy was to try and estimate how much fuel he would need to bring to cut lets say for example 100 cuts of a 20 inch diameter Douglas fir. Which would go like this, 20in diameter tree = 314 square inches/cut. So 100 cuts X 314 = 31,400 square inches which means that it would take 5 tanks of fuel (31,400/6,600) to do the job, or 2.5 liters (estimated). This information is also really handy for estimating fuel usage with chainsaw mills. The bar that I was using was a 20 inch bar.

What the hell is the point of this video. Who buys a chainsaw for "fuel efficiency?"

@wadjaexpect This video is actually more about laziness than fuel efficiency. In my spare time I build remote log cabins which require that I carry all my tools and fuel to some distant location, so every pound becomes a burden to carry. I did this video in order to help myself as well as others to judge how much fuel they might need in a similar situation. As well my friend, this video is about fuel consumption, not fuel efficiency and economy.

Thanks for the scientific review :) Seems to equate to 1516 inches cut per gallon of gas. Not bad.
