Thanks for posting, I've always been interested in the Eni i-Sint oils.

So it's a full synthetic 5W30 that is ACEA C4 rated, so high HTHS (>= 3.5cP), but low SAPS (= 6 from ACEA) and the ZDDP zinc & Phos level.

After 8800km / 5500 miles your TBN had dropped to 2.2 and your iron was at 52 ppm. The TBN seems a bit low and the iron seems a bit high to me, but I don't know much about small Renault diesel engines or how harsh the St Petersburg climate is. Maybe this is within the expected range.

Does your car have a DPF ? If not I would be interested to see how it performs with a higher SAPS and ZDDP oil.

If using recomended oil by manual low SAPS ( ACEA C3 and CJ-4/CK-4 5w-40 and 10w-40 - best choice by my opinoin

How many times did you already change the main bearings (well known defect @1.5 dCi) till now?

 

[Gubkin]

Did never change

Sorry mate, I missed them at first, yes I can see all your other VOA's now.

It did better on the high-SAPS oils, less iron wear and higher TBN
