Thread: Engine break in

    Engine break in

    Hi everyone!! I just bought a 2014 Supercrew with a 302 V-8 and since the owners manual gives very little information about a break in I was curious about how other people broke in their engines

    Don't use CC for the first 1k miles, don't do a lot of hard starts or stops, and change the oil after 1k

    I did 2 or 3 hard starts when I was taking people for rides in it a couple data after I brought it home, do you think doing so will a effect the break in at all?

    ----------

    Dealer said not to change the oil until there is 5000 miles on it because the factory puts synthetic oil in it and if you change it any earlier than 5000 you lose it's effectiveness

    We all know that most people have different opinions on proper engine break in procedure,some say to "drive it like you stole it" or the rings will not seat into their proper positions causing gauging,oil compsution and premature wear and some say to baby it and it everything will slowly fall into position... I chose the middle route...,baby it at for a few days then beat on it for a few days hopefully this will work...

    Do you think I compromised the break in by doing a few full throttle starts?

    Not at all. The most common advice I've heard from several Ford reps is to drive it consistently throughout the RPM range. From soft starts to red lines every once in a while.
