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

In the daily inspection table in Chapter 4, Section 3, 1 of the Rules of the Road, the entry for the lubrication system says to "check that the oil level is within the range shown on the oil level gauge (dipstick)." The procedure in the question (stopping the engine on level ground, waiting several minutes, wiping the gauge once, and reinserting it to check) is not written in the Rules, but it is the usual way to read that range correctly, so the statement is correct.

Can't I just pull the gauge out once and check it?

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.

Why the double dip?

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