I have a 2002 F150 with 4.6L and 220k miles on it. I am religious with the OCI every 4k miles and use Pennzoil PUP 5w20 paired with an WIX XP oil filter. My question is, am I just throwing away filters that can last longer than my 4k mile OCI? I’ve read that WIX XP’s are great for extended OCI’s. I use the same oil filter in my wife’s Cruze 1.4T as well (OCI every 7,500 miles).
