Palio D, I suppose you could shift up at even slightly less than 1000rpm. The inherent low-end torque of a diesel engine would help there.

The easiest way to use the tacho is to notice what rpm you're shifting up at, when you shift according to the speedo. Normally, it would be a similar value from any one lower gear to the next higher gear.

In the Baleno, it is possible to shift up at 1500rpm, which is pretty low for a petrol car. It actually goes lower, to 1200 or so, but I use 1500 as a benchmark. This is possible because, for a petrol, the Baleno has useful torque low down.

Shifting up at speedo intervals will never paint as clear a picture as shifting up at tacho intervals. But please take care not to shift down at high tacho speeds, or you may have an over-rev and cause major damage.
