[allanworks]

a way to under stand it is lets say i have a tapping noise in my engine the first thing that comes to mind is marvel mystery oil there might be better stuff out there but ive learned to trust the stuff .just like lucas,slick 50,engine restore,wd 40,liquid wrench and so on these are things ive come to trust if they dont fix problem then ill try something else.good i love liquid wrench that stuff has saved me a ton of broken nuckels
