The Science Behind the Check To grasp why temperature matters, it is necessary to look at how oil behaves inside the engine. Pull the dipstick out again and observe the oil level on the stick, noting the marks for "Low" and "Full.
Check Oil Cold Static State Guide
The Procedure for a Cold Check Executing a cold check requires discipline and patience to ensure accuracy. The state of the engine—whether it is at ambient temperature or at operating heat—changes the physical behavior of the oil, making the measurement inconsistent if the procedure is not followed correctly.
In these instances, the manufacturer’s specification overrides the general rule because they need you to check the oil while it is circulating to ensure the oil pump is maintaining the correct pressure and volume. Never add oil to a hot engine that is idling above the recommended level, as this can cause a sudden pressure spike.

Follow this sequence to ensure a reliable result: Drive the vehicle onto a level surface and turn the engine off. This thermal expansion means that a hot reading will always be higher than a cold reading, even with the exact same volume of fluid.
