Just bought a 2019 Ford F-150 3.5L Ecoboost with 96,000 miles. Getting ready to change oil for the first time. I don't drive very much especially in the winter up here in Montana. Very short trips in town daily. (I do however run it out on the highway about once a week to get it up to temp and hopefully burn off any condensation in the oil.)
Looking at the CCS testing I'm leaning towards PUP 5W-30. But I am wondering about maybe doing a 0W-30 as recommended in the manual for cold weather. Maybe the Mobil1 AFE. However, with the ecoboost engines I'm worried about fuel dilution and it getting too thin as the OCI goes on. I'm planning to do 4,000 mile OCI's. And after this change doing a UOA to check for fuel dilution.
What do you all recommend?
