Depends on the car. My maths that that my dad's corolla could get 55-65 MPG while drafting a truck at 60 MPH and it was a 1.6L carbed engine with a 4 speed lockup TC only in 4th. ~2300 RPM at 60 MPH in 4th with locked TC. Math was needed due to stop and go traffic at the end of trip, I assumed pre-2007 city fuel economy since the traffic was bad enough to resemble it
