Should I use 4th or 5th gear at 60 mph?

Each car's gear shift position varies slightly, but generally, if the speed has reached 60 km/h, it's better to use 5th gear. The difference between 4th and 5th gear at 60 mph: At 60 mph, 4th gear is around 1900 RPM, while 5th gear is around 1600 RPM. Undoubtedly, 4th gear provides better power, but at a higher RPM. However, 5th gear is more fuel-efficient. The throttle pressure to maintain 60 mph differs between 4th and 5th gear: Maintaining 60 mph in 5th gear requires slightly more throttle pressure than in 4th gear. At 2000 RPM in 4th gear, the power is sufficient to maintain 60 mph without needing to adjust the throttle pressure much. However, maintaining 60 mph in 5th gear is challenging—either the throttle is too light, causing the speed to drop below 55 mph soon, or it's too heavy, causing the speed to exceed 65 mph quickly.
