Semi synthetic and synthetic oil - Peter C
My VW Passet 1.8T has had synthetic oil for nearly 100,000 miles. The dealer replaced it with semi synthetic at the last service. I queried this change and was told that semi synthetic is the correct oil. I have heard that changing from semi synthetic to synthetic can take away carbon deposits and increase oil consumption. Can I go back to synthetic without flushing?
