4.2tdi servicing

[dpetersen]

Gday all.
Have been searching flat out to find the correct info on this but so many different options I thought I’d just ask the questions.
I just picked up my 06 4.2tdi wagon last week and will be giving it a service pretty soon. I just want to make sure everything I’m doing is correct.
Filters - using ryco filters I can get it in a kit (rsk32), it’s about $80 with trade discount. Filter numbers are as follows;
Oil z503 x 2
Fuel z332
Air a1412
Oil capacity 10.5 liters
Make and grade of oil, this is were I am getting a bit unstuck.
I like using Castrol as it’s easy to get and I get trade discount as Supercheap.
Iv been running Castrol GTX Diesel in my zd-di and haven’t had any issues. Am I able to use this in the 4.2?
Otherwise there is Castrol rx diesel (15w40), or Castrol rx super (15w40), what’s the difference between the two?
I also have the option of running CAT deo 15w40 as this is what I use at work for the generators.
Anything else I am missing with the service or anything else to keep an eye on or check out?
Car has about 218000 on it at the moment.
