I know the modern 5+ speed automatics with torque converters that lock up in most gears do just as well as a manual transmission on fuel economy. I’m asking about the older 4 speed automatics where the torque converter only locks up in the highest gear, where the lock up mostly doesn’t happen in city driving.
Look at this:
[1995 Ford F150 Pickup 4WD] 4.9 L, 6 cyl, Automatic 4-spd, Regular Gasoline 14 MPG city 18 MPG highway 15 MPG combined 13.3 MPG user reported

Was the test driver on these tests up shifting way too late or what? The manual city fuel economy is the same as the automatic on the EPA test. Even the user reported economy shows a huge increase with the manual, and that’s combined not just city. A manual should get at a minimum 10% better MPG in city driving compared to an automatic of the time. It should be 18 or 19 MPG city not 14. Do many people drive manual vehicles that badly and the EPA test is correctly testing the vehicles based on the average driver?
