So I have a 1997 Civic DX, and I don't have an RPM gauge.
My friends say:
First gear: 1-10 MPH, I should shift into second.
Second gear: 10-20 MPH
Third Gear: 20-30 MPH
Fourth Gear: 30-40 MPH
Fifth Gear: 40-up MPH

I thought it was kinda weird
Can anyone confirm this and if it's not correct, tell me how fast I should be going for each gears.

 

okay you can feel when the car needs to be shifted
