2.4 JTDm engine oil: Latest advice from Selenia

Out of interest I checked Selenia's Lube Recommender for their recommended engine oil for the 2.4 JTDm engine in my 159. Surprisingly it now recommends their new generation Selenia WR Pure Energy 5W-30 oil, which is a fully synthetic ACEA C2 low ash specification oil.

There's been a lot of confusion and debate online about the Alfa Romeo owner's manual recommending Selenia WR 5W-40, which is an ACEA A3/B4 specification oil as this particular specification isn't usually recommended for diesel engines with DPF's.

I decided to email technical support at Petronas (owner of Selenia) and this is their response:

The engine of his car was born with SELENIA WR 5W-40 that is the product indicated on the manual.

Then FCA engines 2.4 JTD EURO 5 has developed the lubricant SELENIA WR P.E. 5W-30 this product improves the fuel economy.

However you can use both products.

Hoping to have them clear the doubts remain at your disposal for any further information.
