Identifying engine type (and RPO) to determine correct oil

[SkazzY]

Hi folks,

I am having troubles determining engine, or to be more precise the RPO of the said engine on my Citroen C4 (2022). The dealership/authorized service pulled out information where I can see that my car has a DV5RC/EU63 engine with a serial number of 10 Q3DP 1343227, but from what I can find online, the recommended oil for that engine has changed depending on the RPO. Is there a way to find this information. I would also like to get a full list of car specs from the factory, as every list I have managed to get was somehow different :/
The VIN number is: VR7**************[VIN obfuscated, can be read by forum staff]

Your RPO number is 16472

You can find it on the tyre pressure label.

Just checked the sticker, and it indeed states 1647282, I am guessing the 82 at the end references something else? Thank you for the help!

Yes, the final two characters indicate the factory where the vehicle was built. There's a (very) abbreviated list of factories here https://web.archive.org/web/20211110194 ... /RP_Number

Attention Admin - for some reason the Wiki URL is coming up with a 404 error https://frenchcarforum.co.uk/wiki/ORGA/RP_Number . Which is why I had to use the Wayback machine.

Thank you for the info.
One more question:
I did my research, and judging by everything I saw, for my engine I should be using 5W30 Oil FPW9.55535/03 (judging by viewtopic.php?t=75918 and other topics I have found and read). Is my assumption correct?
My local dealers tend to share "balkan approach" (style of thinking that basically says "we have done it like this for many years, it has to be correct"), so you usually get outdated information, hence why I am searching for more wisdom on the forum.

We discontinued the wiki several years ago because it was taking quite a bit of technical maintenance while no-one was adding any new content. The most useful content was moved to topics in the resources section, but this particular data seems to have been missed.
