Answer 2

Depends on what kind of engine. Diesel or gasoline ?

Diesel engine usually run on low RPM (1000-1200 RPM on idle). Maksimum RPM generally around 5000 - 6000. If this is the case, you'll need to change the gear from 1st to 2nd at 3000 - 3500 RPM, 2nd to 3rd at 2700-3000 and more lower on the highest gear.

Gasoline engine run more higher RPM than diesel, usually 1500 - 1800 on idle. Maximum RPM is around 7000 until 8000 RPM. In this case you can get in more higher RPM on changing gears.

Answer 3

once the needle on the tachometer goes well into the red area, that means shift. usually if you hear the engine bouncing off some sort of 'limiter' that's a sure sign you can start thinking about shifting.

Answer 4

You want to watch your rpm not your mph or kpm. Usually shift when you hit 3,000 rpm. But it depends on the driver. I shift higher for some reason idk, I normally shift around 4,000 - 4,500 rpm. Just make sure you don't red line it or stall it out and you'll be just fine.
