Hi guys. Just bought my wife an 04 Passat 1.9 TDI last Saturday. I'm looking through the owners manual, and the are VERY adamant about using only a synthetic 5W40, or if unavailable, a 5W30 oil with VW-505-01 specification. I have never seen this on any high quality synthetic I have looked at I don't think. Does someone know what oil has this spec? Thanks.
