Did I mess up?

After my heater hose blew off I last Saturday night I went to autozone to get coolant as they are open on Sunday and I did not want to drive without any coolant. Well I got six gallons of Preston long life 50/50 and filled her up. Right now it seems to run fine and is just below cold fill line. Should I drain/flush and put in the CAT elc like everyone says or can I wait a little while and not waste the $100 of coolant?

You will want to flush that out sooner then later

its gotta be the correct stuff bud.. and what you got is not it.. it has to hold up the temps that the 6.4 runs at.. the stuff you got wont hold up.. and when you mix coolants.. it gets all jacked up and will start to clog stuff up ... get that preston stuff out of there ASAP! at least get some Ford Gold coolant.. you need to do a full flush get CAT ELC coolant.. thats one of my next things on the to do list..
