2.492 | The other 2 1/2 gallons of B100 I had brought, plus public pump B11 in Effingham, IL. "cost per gallon" is an average of these two costs and two volumes.

14.088 |
2.502 | .985 gallons of B20 at a public pump in Mt. Gilead, OH. That gallon took almost 5 minutes to dispense. I gave up on that one.
I then added 2 1/2 gallons of B100 I had brought with me, and finished filling with ULSD. "Cost of fuel" is the average of the combined prices over the combined volumes.
Driven at 55 mph, not the posted 65. Big difference in consumption rate. | 49.60 |

15.207 |
2.539 | Too cold to blend in biodiesel. I don't want to risk gelling with this +35F to+40F gel temp bio. My local petrodiesel is winterized down to about -20F so a B33 mix would be too risky at zero F. It had been colder recently. | 34.99 |
