You don't say whether it's the 90bhp or 110 engine. If it has a DPF then you need to use low saps C2 5w30 oil. I'd do an oil and filter change every 6000 miles instead of 12000, to avoid the turbo oil feed issue. If it's had regular on time oil changes then no need to do a flush.

Check the VIN and the post it on here and we'll be able to look up all the details using that. The VIN may be found on the outside of the windscreen at the bottom left (passenger side) or on the left hand side as you look into the engine compartment inner wing on a silver riveted VIN plate adjacent the washer bottle filler.

It's a 90bhp.
It does not list a 'PARTICLE FILTER' so no DPF.

Peugeot recommend Total Quartz INEO ECS 5W - 30 or Quartz INEO MC3 5W - 40 but any decent fully synthetic 5W - 30 or 5W - 40 for diesels will do. You'll need 4.7 Litres for an oil change. Recommended change is 20000KM or 2 years under normal conditions or 15000KM under severe conditions, but I'd probably change it a bit more frequently than that.
