The answer options
- Oil seals will leakCorrect
- Timing belt may slip
- Air intake will be blocked
- Clutch pedal will lock
Why that is the answer
Overfilling your engine with oil creates excessive pressure inside the system. This increased pressure can force oil past gaskets and damage engine seals, causing oil to leak out. It can also lead to serious engine damage and excess smoke. Always check your dipstick regularly and ensure the oil level stays between the minimum and maximum marks as recommended in vehicle maintenance guidance.
How this comes up in the real test
Questions from safety and your vehicle appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.
The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
