Well guys i know I'm new here but i have a simply question. I was wanting to add some lucas treatment to my 2001 Power Stroke, but i can't seem to find where to add it at. I know this sounds stupid but it seems like adding it through the dip stick takes forever..............I am sure a few of you are laughing at me right now, but you never know until you ask and no one i know has any idea!! Thanks for the info and please excuse the ignorance!!
