Hello, I'm Danny.
Yes, if you've added an aftermarket additional filter and they are both larger in size absolutely it will require more oil. You stated they possibly hold 1.5 quarts additionally. I would add about a half quart at a time until you achieve the required level on the dipstick. Hope this helps and thanks for using 2CarPros.
