Nope, old wive's tale. Not true with today's synthetic formulations.I am am little concerned with starting to run full synthetic because isn't it true once you put full synthetic in a car you can't go back and use regular oil or synthetic blend anymore or it damages the engine?
The 1.4T is a bit hard on oil - oil temperatures run very high, which can cause sludge to occur with synthetic blend oils. A full synthetic oil is a good habit if it's a car you plan to keep a long while.
