Putting a diesel tank at the shop was one of the best things I have done. Friday afternoon the trucks and chippers get washed, fuelled up and parked ready to rock for Monday morning. It's not that I am getting the diesel a lot cheaper that way, I am saving money by not having 5 men stand around on my payroll at the pump while we fill 2 trucks, a chipper, mini skid etc one at a time. Time is money.
