I'm asking cause we found out the hard, and very expensive, way that with the 1.8 turbo we should have been using synthethic oil. Fixed the problems and sold it. In the past week we bought a 08 with the 2.5. Called VW and they said to ony run synthetic oil. The place that we bought the car from changed the oil and used regular. My question is this....do we need to run synthetic oil? The car as 56,000 miles and I have no idea what the previous owner was using for oil. I am trying to take some preventative measures and make sure we are running the correct oil.
