Got this in 307 Break pre-facelift, absolutely clean with new Liqui Moly synthoil 5w40 and molygen motor protect.
Engine is now doing much better and currently no oil burning.
At 207 000 km. Before it either 5w40 or 10w40 was used but never more than a year old oil or going over 10 000km without change.
Timing chain needs regular changes, used Bosh repair kit last time. So far so good. Also did engine cover resealing.
still alive on my old citroen c4, 360k km and 20 years… burns 1litre of oil every 2k km but ok with that.
