My 6/1 & ST5, at 1,400 ft, running around 1740wh, gave me:
227 Hours YEAR 395,405 Wh 59.5 Gallons 6,645 Wh per gallon 0.262 gl / hr
pump diesel w/10% bio-diesel or some 2 stroke oil for the pump lube
Well, look at that, While I try to keep it loaded up to about 2500w, when "stuff" happens, and the batteries fill up, or I was
still dialing in the charger, I put a lot of lightly loaded hours on it. I don't notice it using oil,
