To confirm . Check the oil on your other cars to compare , Or your neghbors cars . I think you'll find this is consistent . I worked heavy equipment for over 20 years ,which obviously uses much more oil, and all the components (engine , trans , hydraulic) have hot and cold markings (as much as 3" difference) for this reason . Example : a CAT dozer hydraulic tank filled to the hot mark when cold will blow hyd oil all over the deck when it warms up. This happens quite often when we hired a new lube man at the mine .
