I took a 150 mile trip today. My VIC read that i got 16.8 MPG. I filled the gas tank and divided the 150 miles by the 7.4 gallons it took to fill it up. That comes out to be 20.3 MPG. Why is the VIC so wrong? Don’t get me wrong, I’m happy with the 20.3 MPG, considering i i was averaging about 70 MPH with the air conditioner on the whole time. Just don’t understand how the VIC could be so wrong!!!!
