Normal
My wife's SHO was getting water pump done which is the Achilles heal of the FWD 3.5 ecoboost. I have about 200 customers "converted" to the 5w40 oil and in 10+years I have had 0 engine repairs on any of them. I seriously had to wait for my wife's water pump to fail to get pictures inside of an engine that had been running that oil for any length of time.
