Filled my house propane tanks yesterday....$2.75 delivered.....was pleasantly surprised. September is the cheapest month to fill up around here. Farm diesel (30 cent road tax eliminated) was $5.19. I was reading new sources yesterday and apparently crude oil from the Middle East is easier to refine into diesel, whereas light crude from around here makes the best gasoline.....maybe that's the reason for disparity between the two fuels...around $2 more for a gallon of diesel.
