Diesels don't usually need oil between changes. Where's it going?
Leaking pipes to the cooler or the cap of the filter leaking? Not normal to use so much oil.
Burning it I fear but no blue smoke either??It's empty. Fill it up, quick!
Mark's had the French F*ckup Fitters playing with his. Heaven knows what has happened.
The engine had no leaks at and I mean at all.
I changed the oil about 1000 miles ago. Nine litres and a new filter.
Don't forget it's on 211.000 'ish miles but passed the mot on émissions with no advisory.
A little ramp time is needed...
