2005 GP GT


Soooo... the other day I decided take my car to a friends house who works on cars. I needed a oil change and didn't feel like driving all the way to my parents house to do it myself so I figured I have him doit. I usually put about 4.5 quarts in engine but when my friend was doing it it told me to poor the whole 5.1 quarts into my engine and said "trust me" its fine.. I read its to much or fine and also read the it should be at the 3 dot any lower is to less or high to more. So I figured I would ask you guys who own these GP's to what is right. If its to much what is the best way to remove the extra oil?

Thanks!
