help me pick an oil for the PSA/Ford DV6D engine

[madjid]

I have the DV6DTED M which is the 92ps 8 valve version with EGR and catalyst no DPF/SCR
I sourced a lot of cheap HDEO Yacco brand oils locally and I want to know which would work best to provide the best wear protection

PS: running high sulfur fuel maybe around 2000 ppm
the temperature here rarely drops below -5 C and goes up to 45 C in the summer

the engine did 180k km now and it's 9 years old
i do ~ 80% city 20% highway + rarely short trips + couple of engine stop-start daily

Throughout the years I've filled Total 5w30 INEO ECS and for the last 6 oil changes I've filled it with Total 0W30 INEO First as per the official UK Total website recommendations
OCI is 10K km
For the last OCI, i noticed it lost around ~300ml of oil which it didn't use to do before and i think it did just in the last 3k of the OCI not sure though

the Yacco products are : ( from the cheapest to the most expensive relatively per litre )
TRANSPRO 40S
TRANSPRO 65S NewTech SAE 10W40 ( i can tell from the approvals that noack <= 11 | zinc/phosphorus <= 800 ppm | calcium <= 1500 ppm )
VX 500 10W40
LUBE GDI 10W30
VX 1000 FAP 5W40 ( almost 2x the price of TRANSPRO 40S 10W40 )

i also found Castrol Vecton 15w40 ck-4/E9 and and Total 9000 5w40 for a similar price as the TRANSPRO 40S


I mailed Yacco for more detailed information about the products and advice it's been almost 15 days with no reply
+ Unfortunately, I don't have the option to do UOA

Please help i would be very thankful

I’ve never heard of Yacco, are they reputable?

Any major-brand oil that meets ACEA A3/B4, ACEA C3, ACEA E9, ACEA E11 would suffice. These aren’t fussy engines!

There's a link between Yacco and Total I believe. It's a French brand anyway.

before the 8 valve they had 16V versions those got killed by too much soot. Changing earlier rather than later is key.

Yacco is a French brand with a long history. They are a minor player now (well they have never been big) and usually do answer to requests, although you have to write to them in French
Not sure about their link with Total, but it would make sense that they'd buy their base oil from them.

(I have some Galaxie Competition in my stash that I picked just for the red jug one day that it was on sale at a store)

yup at least here
can you take a look at the oils I mentioned?
I can provide you with all the details i know about them if needed to make it easier i don't want to bother you much
i know that all of them are sufficient but I want to know how they stack in terms of wear protection because engines here are quite expensive and fuel is very cheap

I'm doing 10k OCI I think it's fine enough although TRANSPRO 65S NewTech SAE 10W40 has a TBN of ~13.5 i guess even 15K OCI won't be a problem?

tbn doesn't protect against soot, it could 100 and you can't increase the oil life 1 mile.

 

[Popsy]

How's the EGR situation, and when you say 10K I'm assuming 10K Km, right?
I think like Jetronic says you should watch soot before TBN.

thanks for the info much appreciated
i did some digging I guess it's the job of dispersants
is there an easy way to watch for soot like putting some drops on a towel regularly or something? I may delete the EGR if it raises much concern
the gov regulations are low it can pass without EGR

I'm usually easy and progressive on the throttle i guess it helps with soot formation
but a worn engine = more blowby = more soot in the oil

i know I'm asking for horribly inaccurate statements here but when you don't have UOA there's a lot of guesswork involved :[
I'm very passionate about it i hope i can achieve something this time around

yes 10k km
the EGR has never been touched or cleaned

Yes, putting a drop on some paper would show you. The soot should get carried as far as the oil spreads, if the soot stays to center of the spot, you've exceeded what the dispersants can handle.

thank you i appreciate your help
