Question

DentroTest · Accepted Answer

The oil level is checked with the dipstick with the engine off and cold, and with the bus on a level surface, so that the oil has drained down into the sump and the reading between the minimum and maximum marks is accurate. With the engine warm and running at idle, or hot right after a trip, part of the oil is still distributed around the engine and the reading may come out below the real level. It is advisable to always follow the instructions in the vehicle manual.
