Greetings, this is my first post but I have read quite a few topics. I am wondering what's a reasonably long OCI for my vehicle. I have a 2014 F-150 5.0 4x4 with 24K miles. I bought it used with 13K miles, had a free oil change at the dealer now this will be my first change on my own. I am planning on using Pennzoil Platinum 5W-20 with a Royal Purple Extended Life oil filter. I drive 90% on the highway. How long do you all think I can extended my oil change interval? I know Ford recommends 5K, but would like to extended it as much as possible. Since my last oil change with Motorcraft oil I have driven 5.5k miles and the oil life indicator shows 45% life left.
Thanks for the input, right now I'm thinking maybe 7.5k oci.
