Usually measuring what I get from about between 3/4 to 1/4 tank. At an 18 gallon tank those marks are roughly 4.5 gallons. So I’m calculating miles on the tachometer divided by how many gallons it takes me to get up where tank was at when I last filled it.
I agree it’s AWFUL fuel economy. So I’m trying to figure out if it’s the injectors or what.
