When should you especially check the engine oil level?

Explanation: An engine can use more oil during long journeys than on shorter trips. Insufficient engine oil is potentially dangerous: it can lead to excessive wear, mechanical breakdown and expensive repairs. Most cars have a dipstick to allow the oil level to be checked. If not, you should refer to the vehicle handbook.
