Im about to do an oil change on my 2002 Tacoma V6 and i was courious how much oil comes out of the filter? Im taking the filter off through the wheel well. Also im planning to order this http://parksoffroad.com/tacomamods/fumoto/fumoto.htm to make oil changes easier but since i have to remove the skidplate so i dont get oil all over the place is it worth while to order this valve? If i do get this valve i do not plan on taking the skid plate off but if oil gets all over the place from the filter to me it does not make sence to purchase this valve. Thanks.
