My fuel consumption is somewhere between one and one and a half gallons per hour working hard at full throttle.
Oil consumption has dropped from maybe an ounce per hour during the first few days, to insignificant after about 95 hours of operation.
My usage style ranges from (rarely) puttering along just above idle as a powered wheelbarrow, through mowing with the 60" deck at full throttle on moderate slopes, to very hard digging in heavily rock-infested clay.
Hope this helps,
Dave
