Question 5701
For economical driving, it is recommended to shift gears in gasoline engines...
- between 2,500 and 3,000 rpm.
- between 3,000 and 3,500 rpm.
- between 1,500 and 2,500 rpm.
Show answer and explanation
Correct answer: between 1,500 and 2,500 rpm.
For economical driving with a gasoline engine, you should shift up between 2,000 and 2,500 revolutions per minute, within the 1,500 to 2,500 range. This keeps engine speed low and uses less fuel. Waiting until 3,000 rpm or more means revving the engine higher than necessary.
