2017 Ford F150 3.5 NA. Bought new, has appr 8k miles. Was originally driving on short, medium and longer trips with no real rhyme or reason, just every day driving plus for work occasionally. Moved into town, and at about the same time got a work truck. Now the truck doesn't even get driven every day, and when it does it is for really short trips, with a longer or long drive every now and then. For example I could not drive it for a day or two, then start it up, drive maybe 2-3 miles to the grocery, shut it down, then 30 mins later start it up and drive back 2-3 miles home. Or on a weekend start up, drive 1-2 miles for coffee, hit the drive through and just go home. Or after basically sitting for a week I could take it on a 3hr highway drive to see family and then home. So very short, infrequent trips, and occasional longer ones. This has been going on for a couple of months. I make a point of driving around occasionally, take the highway for a bit, go the long way home etc. just so it has a chance to warm up and run for a while. This is the projected future of this truck. Suggestions on best protection plan for long term reliability? Oil? Filter? OCI? Other? Thanks, Matt.
