Correct answer

  • BEntre 1.500 y 2.000 rpm.Between 1,500 and 2,000 rpm.
Explanation

In diesel vehicles, it is recommended to change gear between 1,500 and 2,000 rpm. Diesel engines work most efficiently in this range, which gives lower fuel consumption and lower emissions. Changing at lower revs can lead to a lack of power, while changing at higher revs increases consumption and engine wear.
