Question 4924
In a vehicle with a diesel engine, once the engine has been started, it is advisable to...
- rev the engine in neutral so that it warms up.
- wait a few seconds before starting to drive.
- start driving immediately.
Show answer and explanation
Correct answer: wait a few seconds before starting to drive.
With a diesel engine, you should wait a few seconds after starting before driving off so the oil can reach all the parts properly. Do not rev the engine while stationary to warm it up, because that uses fuel and wears it out. Driving off right after starting is recommended for gasoline engines.
