“I looked up a couple of studies. One had blowers using 47 3/4 gallons an hour”
I don’t b believe you
I used my Stihl 2 stroke leaf blower for at least an hour yesterday.
I filled the tank three times from my one gallon gas can.
The gas can was still about half full when I was done.
So, I MIGHT have used 1.5 quarts in about an hour of constant use.
