Me personally, I don't believe anything anyone posts on youtube and don't bother posting there myself.
that is a little ignorant as well. not everything on youtube is a lie. there are some very good, professional documentaries on youtube that use factual information and not opinionated and biased garbage.
sorry, i'm not meaning to call you out or start anything, i am just trying to make a point
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
