Purchasing Diesel

The last time I paid money for fuel was October 9th. Currently the odometer reads 219248, so we've driven 1433 miles since our last fill up. The diesel tank holds 14.50 gallons which computes to 98.8 miles per gallon of diesel. Obviously, most of our driving consumes WVO but that is basically free except for the $10 or so we spend each month on filters.
