    I have a 2009 Ranger with the 4 cylinder. What do you folks think about adding STP during an oil change?

    Thanks, Smitty

    I would not put it in. Its only going to result in thicker oil, which you could do the same by going up a weight in oil. And it'll have lower fuel economy as a result.
