I just spoke to a friend who was hanging out with a ford service manager. He was talking all kinds of crap how the 3.5 use 1 qt every 1000 miles. Saying it’s not a good motor. I see there’s a TSB for the 2017-2019. Did they do something different in 2020? I’ll keep and eye out on mine, but was wondering. Thanks
Your first mistake was listening to hearsay; your second mistake was trusting a service manager to provide technical information. The TSB you are referring to was for valve cover replacement on certain trucks built before 4/1/19. 2020 models were not affected, as they already had the updated valve covers.
