Taking into account that your engine is quite old and that it does not have DPF most likely it was
not designed for low/mid SAP oils (Motul oils you specified). However to be 100% we need to see the manual.
Here is the manual for the car:
I understand the specific Motul oils (designed for engines with DPF) are not really recommended for my engine...

It's always best to stick to the recommended grade in the owners manual, as long as you do that you can't go wrong.
I've checked on my data system for a 2000 206 2.0HDi (should be similar) and this is what it comes up with, looks like you have plenty of artistic licence.
Engine oil ACEA B4 SAE 5W-40 From -30 °C to 50 °C
Engine oil API CF SAE 5W-40 From -30 °C to 50 °C
Engine oil ACEA B3 SAE 10W-40 From -20 °C to 50 °C
Engine oil API CF SAE 10W-40 From -20 °C to 50 °C
Engine oil ACEA B4 SAE 0W-30 From -45 °C to 45 °C
Engine oil API CF SAE 0W-30 From -45 °C to 45 °C
Engine oil ACEA B5 SAE 5W-30 From -30 °C to 45 °C
Engine oil ACEA C2 SAE 5W-30 From -30 °C to 45 °C
I run a 5w-40 ACEA A3/B4 in our 1.6HDi non FAP cars, the fuel economy oils are just that so they wont protect the engine any better, just give you very slightly better mpg due to reduced oil drag (usually compared to a 15w40 mineral oil).
We use Total engine oils and Motul transmission oils in our workshop, both excellent so you will be doing the right thing with either companies so just get the application right.
Hi Riggaz,
Thank you for your comments.
I recently put the Motul Motylgear 75W80 to the gearbox after a bit of research and it runs fine ever since.
Thanks for the temperature table. As you can see, in this climate and according to that chart, I can use any of the listed viscosity oil all year round. The temperature rarely drops below 0 or goes above 25 degrees any time of year, so from the temperature range perspective this place must have the easiest working conditions for an internal combustion engine on the planet across the season
.
I understand the viscosity differences, etc., but just looking for a good product that I will stick with. The current oil (which is 5W-30 AFAIK) seems to work fine, the engine burns no oil and is very economical. It actually is the most economical car I have ever had and I had a good few in the last couple of decades...
