loosing coolant and misfire on start up

ford focus st 2006
very easy to use and really works. I was loosing coolant and misfiring on starting up. I looked at YouTube for answers and Scotty Kilmer recommend steel seal so I got 2 bottles for 2.5L engine. I poured it in and went for a drive for around 30 minutes and let it cool down over night. in the morning toped up coolant and started it up and no misfire. a week later it's not lost any coolant and no more misfiring I'm very happy and i would recommend.
