Correct answer
The manufacturer’s procedure, with the vehicle level and the specified measurement conditions observed.
Follow the manufacturer’s procedure with the vehicle level, observing the specified engine condition and waiting time. A dipstick check is generally performed with the engine stopped and after allowing oil to return to the sump. Some manuals prescribe a cold check; others prescribe warming the engine and then waiting. No single temperature should be imposed on every vehicle. The level must remain between the marks or within the specified range, without overfilling.
