You can use 5W-30 on that engine (euro5 I guess), on newer (bluehdi) it is recommend to use 0W-30.

 

I would recommend Mobil 1 ESP I have used it for a good few years in my DS and family cars with no issues. I used its predecessor Mobil 1 Diesel in my 307 and racked up 260K+ miles with no issues.

It is expensive from some outlets but OPIE oils sell it at a realistic price

 

Thanks for the advice. I have looked on the log book now and have the exact engine number
508 Allure SW HDI diesel 1997cc engine number DYYF4077635.
The car variant is 8ERHH

 

My DS is RHH engine, at the end of the day any good quality low SAPS C3 5w30 or 0w30 oil (which meets PSA B 71 2297) will be fine

 

Great thanks for your help.
