[Vwdiesel] TDI oil

[TexasTDI]

"castrol claims it meets API CG-4, but has not gone through the steps to
actually get it approved."

CG-4 is outdated.  The minimum rating you should use is CH-4.  But you
really need to use a CI-4 oil in the TDI.  CI-4 oils are the only oils
specifically designed for use in diesel motors with EGR systems.
