This is a very subjective question. On any vehicle, there isn't an exact point at which you must change gears. It all depends on your driving style. Some like to just cruise at low revs, while some like to scream. In general, most engines are tuned to operate comfortably between around 2000rpm~4000rpm. Therefore, I guess it doesn't really matter when you shift, as long as you keep the revs between that comfort range.

It's all done by feel and experience. But in general you should change up as soon as the engine can comfortably manage. The higher the engine revs the more fuel you are using and the more pollution you are creating, so you don't really want to be rattling along at 40 in 3rd :o). Obviously if you change up too soon the engine may stutter and cough, particularly when it's cold, and you may even stall. Leave changing up a bit later when going up hill.

The general rule is to change gear when the RPM's are high enough for the engine to keep accelerating in the next gear...

Most car manufacturers set the rev counter so that the maximum power is produced when the needle is upright. If the needle is past the verticle then you are in too low a gear. Apparently it's all to do with how well the engine sucks in air .
It's all relative really. If you want to drive fast - Change up early
If you want ecconomy - change up on max power
If you want to wreck the engine - change up too late.

If you don't know when to chage gear by now you shouldn't be on the road. Gears are changed according to the conditions, not at a pricise rpm. What would you do if there was no rev counter??

Hi - I have a Peugeot 206 and change gear to maintain revs at around 2 on the rev counter - up to 3 at high speeds. This tends to be 5th gear - over 40mph, 4th gear around 30mph, 3rd around 20mph. I hope this helps!

Don't worry as much about the rpm's. listen to your motor and feel how it is. some manuals don't even have a tac.
don't let your engine wine, but don't be so slow to let it putter and struggle,
aproxement driving speed is 2k rpms, shifting is 4k rpms. but these are aproxement figures.
drive by feel.
oddly enough, my manual does not, but my automatic of the same exact car does. i have no idea why

0-10mph 1st, 10-20 2nd, 20-30 3rd, 30+ 4th is a rough guide, but the revs of the engin is the best way to tell

Listen to the engine rev. When the gear needs to be changed you will feel and hear it!!!

As mentioned above, listen to the engine. Don't you remember learning to drive? If you spend your time looking at the RPM you'll crash!
