Ch. 4 · Pre-Drive Conduct

When checking the amount of engine oil, stop the engine, wait several minutes on level ground, pull out the oil level gauge once and wipe it with a cloth, insert it again, pull it out once more, and confirm that the oil level is between the upper limit (F) and lower limit (L).

[True / False · Easy]

Answer: ✓ True

Explanation

The Rules of the Road, Chapter 4, Section 3, Vehicle Inspection, specifies the method for inspecting the lubrication system: after stopping the engine, wait several minutes on level ground, pull out the gauge and wipe it, insert it again, then pull it out and check that the oil level is between the upper limit (F) and lower limit (L). The procedure in the question accurately follows this regulation and is correct.

No — that's the trap. You pull it out, wipe it clean, insert it again, then pull it out a second time to get an accurate reading between F and L. The statement is true.

The first pull clears residue. The second pull gives you the real level after the oil settles on level ground.
