How quickly should the oil pressure come up to normal once you have started the engine?
Correct answer: In a few seconds.
Answer options
- AIn about 2 minutes

A healthy engine builds normal oil pressure almost immediately, within seconds of starting. If the gauge stays low, shut the engine off at once, because running it without proper lubrication can quickly cause serious damage.
