Castrol Edge

[sambulance]

Hi all

I have always used castrol edge for my oil service. Usually I use the 5-40 turbo diesel with the engine being a tdi. Although the castrol website among others now recommend the 5-30. Does this oil do any better in the engine as it is actually cheaper than the turbo diesel type. Any thoughts? I don't know much about oil but they both meet the oil spec necessary.

Thanks again for the good replies to all my questions

if its got a pd engine in (x-reg onwards ) then its a special oil only-----------disregard castrols books , I even ignored myowners  handbook that recommends 5/30 oil !  

 

Volkswagens pd engines have pd-specification  oil and nothing else.

 

other engines use 5/30 or 5/40
