Question

DentroTest · Accepted Answer

To check the engine oil level reliably and safely with the dipstick, it is essential that the truck is parked on completely flat and level ground. If the vehicle were tilted forward or backward, the lubricant would shift inside the sump, which would give a false reading (wrongly showing a level above or below the real one). Likewise, as a rule of good maintenance, the measurement must be carried out with the engine off and cold to ensure that all the oil has settled at the bottom of the sump.
