VW states synthetic.

VW spec is 5w-40 full synthetic - we use Castrol Syntec 5w-40 at our dealership.
If you are a VW dealer tech then e-mail me.
Best to use a diesel rated oil for both of your diesel engines. A TSB in 1999 says to use synthetic 5W-40 oil in TDI engines. Check the desired diesel ratings in the owner's manual. If VW or ACEA ratings are listed, look for those exact ratings. If API ratings CD, CF-4, and/or CG-4 are listed, look for the more current API CH-4 or CI-4 (API CF can fulfill CD, but not CF-4 or CG-4).
Yes - I'm a tech at a VW dealership - if you want to email me, my address is driverswanted77 at yah-whoo dot com.
