I know this has been asked before but everyone seems to have a different opinion.
Usually I use 5-30 Fully Synthetic (504.00/507.00 grade)
I've got quite a large quantity of 5-40 F/S Miller PD oil that conforms to 505.00/505.01
Is this oil suitable for the 2.0 TDI on fixed (10k) interval servicing? the service book seems to say yes, but as said previously there are lots of opinions.
