Hi all. I did the first oil change on our 2104 Expedition with Pennzoil Platinum HM 5w30. Bought 2 5qt jugs (7qt fill), ran that for 5k miles and did the second change with the remaining 3qts of Platinum HM and the balance with regular Pennzoil Full Synthetic 5w30. Looking forward I'd like to find a more frugal option. I feel like Pennzoil Platinum is wasted on a 5k drain interval but wouldn't like to extend OCIs because of the 5.4 3v's reputation for being sensitive to long drains.
