I am from Italy, so sorry if my English is not very good. Analysis by Blackstone Laboratories. Vehicle: Renault Clio 1.2 74 kW (turbo) Euro 4 year 2009; engine: D4F 784. Kilometres on the oil: 34,000 (21,000 mi) (estimated hours: 1150). Kilometres on unit: 132,000 (82,000 mi). Make up oil added: 1.9 litres (2 qt). Number of months the oil was in service: 36. Driving conditions: 90% city, 10% highway. Estimated average length of trips: 8 km (5 mi). Many short trips. I used to change the oil every 20,000 km (12,500 mi). At the previous service (98,000 km on unit) I replaced the air filter and the valve cover gasket. Standard oil filter (brand: Tecnocar; 66,000 km (41,000 mi) on it) was replaced 2 services ago. Blackstone Laboratories comments: Thanks for the note about the valve cover gasket. That work may be related to the high iron and copper readings, although they were high in 2015 too, when presumably no work had been done, so maybe not. You're running about oil about five times longer than average, so that's part of the reason for the extra metal. Fuel is present at 2.0%. Silicon is a little high, maybe sealers from the new valve cover gasket. It wouldn't hurt to check the air filter anyway, just in case. Insolubles look good and the TBN still has active additive left. Try 36,000 km next.

17 kilos max. Filter media is disgusting and even the paper towel is spotted black as forest night. Aging vehicles with turbos need what senior citizens need...... better meds and TLC. If I had to be reborn and switch Hemispheres next time, I'd want to live in Italy (pasta & vino) or Sweden (married to a real, pure blonde).

Filter was still working, yet it was getting caked heavily. Probably worth cutting the runs a little or look for a better filter.

Yeah ... might be forced to filter (eat) it's own. I wear progressive glasses and on an iPhone ... but did Blackstone say to run longer ?

Standard oil filter (brand: Tecnocar; 66,000 km (41,000 mi) on it) was replaced 2 services ago. 41k miles on a "standard" oil filter crzy Blackstone said to go farther but I would be changing the filter every OCI 2cents

Wow, my friend, you need to atleast change the oil filter mid-way through that interval. Blackstone suggesting you go longer is wrong.

Got to look at the PPM per mile, because the mileage is so much longer than what folks normally run. They really aren't high, for the mileage. Only one that jumps out is copper IMHO, iron is fine. OP: I'd change the filter every OCI, that kind of mileage on such a tiny filter, it was probably in bypass much of the time at this point.

This is a 1.2 liter diesel? Is 0w40 the recommended grade?

Looks good to me, engine seems to like that oil and wear metals are below normal on a per mile basis

The D4F 784 engine requires a 0W-40 grade oil if the environmental temperature is below -25°C (-13°F) and a 5W-40 grade oil if the environmental temperature is above -25°C (-13°F). Furthermore, the engine requires the Renault RN0710 specificaton. As Mobil1 New Life 0W-40 oil does not meet RN0710 specification, at last service I switched to Motul 8100 X-clean 5W-40 oil.
