Multiple Choice

Ensure the dipstick is ___________ when put into the tank.

Explanation:
When you measure fuel in a tank with a dipstick, the reading is based on the vertical depth of fuel from the bottom. Inserting the dipstick vertically allows gravity to position the fuel along the stick consistently and lets the graduations reflect the true height of liquid. If you put it in horizontal or diagonal, the fuel can cling to different parts of the stick, slosh, or sit against the tank walls, giving an unreliable reading. Placing it parallel to the tank wall would also fail to sample the tank’s depth correctly. So the proper orientation is vertical.
