B-99 versus Standard Diesel in mileage
I ran a distance test for mileage performance between B-99 and standard diesel. This is the result:
2005 2wd 2500 Dodge Cummins TD-no load-strictly truck weight and two passengers
Area Driven: Delaware to SW NY and Back
One way miles: 380
B-99 mpg-18 Fuel cost for B-99 $3. 00 per gallon
Standard Diesel mpg-21. 5 Fuel Cost for Standard diesel $2. 90 per gallon
B-99 gallons used on first leg- 21@ $3. 00=$63. 00
Standard diesel gallons used on return- 17. 67@ $2. 90=$51. 24
Fuel Volume difference- 3. 33 gallons
Trip cost difference between B-99 and Standard Diesel=$11. 76 more for B-99
Considering these are highway miles with an average speed of 65 mph, anyone driving 1000 miles or more a month, all highway, would cost the driver $31. 77 more for B-99 use.
I think you can understand that commercial drivers are likely to shy away from B-99 until the price gets lower than standard diesel. And this does not factor in the costs of filters and possible fuel line replacement for older vehicles.
It is a shame that so few states give the end used any tax benefit for purchasing B-99.
In Delaware, the producer/retailer gets the tax break, yet it does not seem to reach the customer at the pumps.
