I use my 2002 Expedition 4.6 mainly towing a bass boat about 100 miles one way to a lake. I put about 4-5k miles per year with about 80% towing. Highway RPMs are 2600-2700 with OD locked out. There are a few hills that require a downshift to 2nd and RPMs get to 4000. Other trips are usually short and around town.
This engine has about 130k miles. Original engine disassembled itself shortly after the oil pressure light came on while towing.
Owners manual recommends 5k OCI.
I'm looking for suggestions on OCI and oil/filter, and any other thoughts.
