In what conditions must the bus be when the engine oil level is checked?

Question

DentroTest · Accepted Answer

To measure the engine oil level accurately with the dipstick, the bus must be parked on horizontal, level ground. If it were on an inclined surface, the oil would move toward one side or one end of the sump and the reading would be false, too high or too low. Whether the level stretch is at the top or at the foot of a slope makes no difference: what matters is that the ground is horizontal.
