VW 505.01 - Audi A4 1.9 tdi - PD

Hi guys!
I'm here as I'd like to ask for your help choosing the right oil for my car.
The car has around 110k kms on the clock and till now I have always used Castrol EDGE Turbo Diesel 5W-40 (or Magnatec Professional B4 5W-40, that is exactly the same oil but with a different label) http://datasheets.bp.com/bpglis/FusionPDS.nsf/0/6CA628996B77DD50802578DA0061Mobil Delvac 1F5/$file/BPXE-8K8KLX_0.pdf
I've read everywhere that I could use (with excellent results) either Shell Rotella T6 5w-40 or Mobil 1 Turbo Diesel Truck 5w-40 or Mobil Delvac 1 ESP 5w-40; the problem is that here in Europe I can't find any of these (if I could find Rotella T6 i'd use it for almost everything

...) and the only 5W-40 HDEO I can find is Mobil Delvac 1 5w-40 (non ESP).
As Castrol is a grp III, low-saps, API SM oil, it'll probably have really low P and Zn and for this reason it'll perform quite poorly in my PD engine. A good oil to use could be RedLine 5W40, but it has become really expensive here in Italy (19€/qt = 25$/qt), so I was thinking of switching to Mobil Delvac 1 5w-40 (non ESP). What do you think about it?
Thank you very much! Bye!

I would estimate that Delvac 1 non ESP would do very well in your 1.9 tdi.

OK, thank you!
I think I shouldn't have any problem with D1, also because my A4 doesn't have a DPF, so using a CI-4+ HDEO instead of a CJ-4 shouldn't make any difference, right?
Thanks again! Bye!

I belive that rotella is named rimula in europe.

you're right ac_tc, in Europe Shell HDEOs are named rimula, but unluckily there is no 5w-40 CJ-4 version of rimula, but only a 5w30 named rimula R6 LME (tds: http://www.epc.shell.com/Docs/GPCDOC_Local_TDS_Germany_TDB_Shell_Rimula_R6_LME.pdf msds: http://www.epc.shell.com/Docs/GSAP_msds_00391013.PDF ).

Rimula R6 LME is an ACEA E6 oil, withCJ4.
Being in Italy (if not living in the mountains in the winter), R6M 10W40 (1.9% ash) would do OK, but the TBN of 15.9 which is what the high detergent additives accomplish is really overkill for staying in western/central Europe.
Rimula oils are formulated differently than Rotella oils.

Thanks Charlie, I didn't know ACEA E6 oils had even lower limits.
In that case I think I'll switch to Mobil Delvac 1 5w40 CI-4+ so that I can have at least a 5w-40 grade oil.
Thanks! Bye!
