So i have this weird problem with my 7mge, it has 83k orig miles on it and when i want to check the oil, i need to make sure the car has been run all the way warmed up and everything first before i shut it off to check the level. If i decide i want to move the car before checking and jsut run the car a few mins and then check it, even letting it settle for a few minuets, it will show a low oil level. it will be about 1/2 to 3/4 quart low. If i drive the car and get it hot and everything and then check the oil itl be all the way full. Whats up with that?
