Has the Crown Vic also been switched to 75W140?? My manual for 2002 says 80w90, but I've heard Ford has abandoned this in favor of the 75w140. True or false?
I don't know of any special change ,
However, 75W140 is synthetic base where 80W is mineral base.
Have drained out 80W ,cleaned some and installed 75W140 , no problems.
Synthetic costs more too.
