I have used synthetic for over 10 years and have not had one of these problems. engine runs smooth and trans shifts smooth.
Luck I'm guessing ,I switched out a car and so did a mechanic working for me , we both had our cars leaking like the Exon Valdez on crank seals. It also depends on year of engine newer engines will be built with viton seals, anything after 2000 most likely
