I usually have the Ford Dealer change the motor oil using my supplied Redline oil but due to the Holiday season there was no availability even for a kind person such as me!
I changed it early today on Christmas eve and @ almost 60K on the car did not hear a Peep of a rattle after filling her up with oil on startup and guess the pump is working as designed. Z
BTW with a Brand new Jeep in the driveway I still enjoy driving the SHO like it was day one!
Merry Christmas. Z
