Backward Compatability?

[listerone]

Just curious about something....I'm close to buying an '06 Jetta TDI and am wondering if the VW 507.00 specification includes all of 505.01's specs and adds qualities of its own.IOW,can 507.00 be used in a vehicle where 505.01 is required?

TIA!

507.00 seems to be incompatible with silver top followers, I think.

I'd be inclined to use Shell Rotella T6 5w40. It seems to be a forum favourite and provides excellent protection for the sensitive camshaft of the PD engine. I'm on my first OCI with it (new cam) and I think it's all I will use from now on.
