How can a physical device taking an actual depth measurement of oil be misleading?
When the engine is cold and all oil has drained to the pan, is the ACTUAL measure. When hot, the measure on the dipstick is the operating level as the cylinder heads contain oil.
The oil filter is always 100% full so that is irrelevant after the first start after an oil change with a new filter.
The oil dipstick is a bet????
