DF, actually people are normally in one gear higher than what the manufacturer recommends. If you notice, say at a speedbreaker, a person is typically in 2nd. But for the speed at which he is, the manufacturer would have recommended 1st gear.
Now I am more confused now than earlier.
Can you guys please e more clear

<10 km - 1st Gear
10-20 - 2nd gear
20-30 -3rd gear
30-40 - 4th gear
40-50 - 5th Gear

The above is typical manufacturer recommendation. This leads to Lugging and lower FE. Don't bother about Gear 1 it should be used only to start or when you come to halt. For most conditions you start with 1 and switch to 2. Switch to 3 only after 30 and 4 th gear only after 40km and to 5th gear closer to 60kmph. This is what I meant one needs to be in a gear lower than what is recommended by the manufacturer. Better recommendation is maintain an RPM >1600. If you have RPM meter to check this out.

Hope this clarifies.

The best way to enjoy a common rail engine is to upshift at a point where the next gear picks the revs from 2000rpm.

Default Re: Migrating from Petrol to Diesel CRDI cars:How to drive better ?

Is it better to let the RPM rise in a lower gear (to avoid clutch use) or is the proper way to saving clutch / engine to upshift to a higher gear and bring down the RPM?

I am confused on this aspect.
