The engine's torque peak is at 1900 RPM and HP peak is at 3750 RPM. Following the shift at NO LESS THAN 3000 RPM rule keeps the engine operating in this range. This rule applies whether driving gently or doing spirited driving. When you need maximum acceleration at wide open throttle (WOT), wind it all the way up to 3500-4000 RPM before shifting.

When should I shift my diesel turbo?
If you want to shift fuel efficiently you shift in smaller turbo engines to drop in the next gear to about 1500rpm. As different cars have different gear ratios it is very difficult to be specific. Very large turbo Diesel tick over at 200rpm and peak at 1200 to 1500 rpm these would be shifted much earler.
How should you know when to shift?
Generally, you should shift gears up when the tachometer is around “3” or 3,000 RPMs; shift down when the tachometer is around “1” or 1,000 RPMs. After some experience with driving a stick shift, you'll be able to figure out when to shift by the way your engine sounds and “feels.” More on that below.
What rpm is best to shift at?
In general, it's best to shift up around 3,000 RPMs (3 on your tachometer) and down at 1,000 RPMs (1). Low RPMs are best for efficiency, but every vehicle is different. If you shift any lower than 1.5, you're likely to stall out.

At what speeds do you shift gears?
Remember each car will be geared slightly differently, but a good rule of thumb for changing gears is that first gear is for speeds up to 10 mph, second gear is for speeds up to 15 mph, third gear is for speeds up to 35 mph, fourth gear is for speeds up to 55 mph, fifth gear is for speeds up to 65 mph, and sixth gear ...
What gears for what speed km?
5th gear and beyond 5th gear is typically used for speeds above 80 km/h depending on the gearing of your vehicle. For manual transmission vehicles with more than five gears, the remaining gears will be the overdrive gears fulfilling the same purpose of lowering the engine's revolutions.
What RPM is a diesel engine most efficient?

What happens if you shift too early?
If you shift too early, you run the risk of lugging your engine, asking it to move your car forward at an unnaturally low RPM. For more details, and a side-by-side comparison of the fuel efficiency achieved in 2nd, 3rd, 4th and 5th gears at identical speeds on the same stretch of road, watch Fenske's video below.
Does high RPM hurt engine?
The absolute most stress on an engine occurs at high RPMs. The forces acting upon the rotating assembly are exponentially increased with RPM. That also increases the magnification of any oiling inconsistencies (as small as they may be nowadays), which can be deadly to engines.
