I filled up today. Total Milege on Prius: 994, Miles this trip: 202.5, Gallons put in: 3.39. This was 95% city/ 5% highway. Temperature range: 62-82 degrees. Note: No heat or A/C used this week. End result: 59.7 MPG. On board computer said 50.7. This was the same way as last time. I filled the tank on the middle speed. After the 1st shutoff I continued filling up to the next dollar. I am quite pleased and will let you know how the next fillup reads using the same method. B)
