Old girl a new life

I've heard nothing but good things about these guys products, so I said I'll try them out. I ordered a jug and put some in a 260k mile 7.3 that had never seen anything in its life but diesel and 15w40. I rescued the old girl from going to the scrap yard. With some love and hot shots additives she's sounding better than ever. I'm using the oil,trans, and fuel. But as of right now this stuff is doing what it promises.
