My oil cooler is going to increase capacity, however, when your oil cooler is mounted with the fittings facing up, you will disregard this extra capacity as it will never show up a difference on the dipstick, and it will not drain out when you drain the oil. So theres maybe another .5 quart in my oil cooler, but I dont see it when doing the changes. I am sure the hoses going there possibly add another 1/4 quart to my change. I cannot recall how much oil it took before I had the cooler in there.

So everyone's setup, once modified, will be a little different. After a couple oil changes you will just notice how much your car takes during a change. Until then, just do whatever it needs to keep it between the lines and dont stress too much about slight variance on the reading.

Like others said, just drain out a little oil and refill to the proper level.
