108500. my oil pressure gauge is reading very high. my car is not running hot. I found some liquid underneath the car this morning and it is a honey color and not very thick. I checked the oil stuck and it shows oil although that color is more of a brown as compared to what i found on the ground. I put two quarts of oil into the car and the pressure gauge did go back down some but not to normal.

what could it be?
