Passat 2005 Running On Used Soy Oil And B100

My fuel is getting low so today I’m going to drive around with a 5 gallon jug in the trunk. As soon as I see the fuel light go on I’m going to pull over and add the five gallons and record the mileage on the odometer. Then when the fuel light goes on again I’ll be able to calculate my mileage pretty accurately. The sensor is programmed to go off when there is 2.1 gallons left in the tank.
