Show the correct answer
Correct answer
B. Between the "MIN" and "MAX" levels.
Explanation
In the photo, the metal tip of a dipstick with notches that mark the measuring range. A correct oil level means an oil mark between the "MIN" and "MAX" marks - answer B.
You take the reading on level ground, a few minutes after switching off the engine: you pull out the dipstick, wipe it, push it in all the way and take it out again. An oil mark between the lower and the upper mark means that the amount of oil is within the limits set by the manufacturer. A level above MAX (answer A) means the engine is overfilled: the crankshaft starts to froth the oil, the pressure in the crankcase rises, and oil may leak through the seals or get into the combustion chamber. A level below MIN (answer C) means too little oil to lubricate the engine reliably, especially on slopes, when the oil moves around in the sump. You top it up in small amounts and check the level again after each one, so as not to go above the MAX mark.
