Hi,
My E270cdi is consuming a lot more engine oil since last oil change. My oil change interval is at every 7500 km. I use Mobil1 Delvac 5w40 and it takes 6.5 litre oil on every oil change. The mileage on last oil change was 185k and i topped up 1 litre at 188k. On Sunday while driving a message popped up in instrument cluster to 'add 1 litre at next refueling' when I got home after 5 minutes, I let the engine cooled down and in evening when I checked oil it showed 4.5 litres oil.
On Monday instead of adding 2 litres of oil to top up, I went for a complete oil change @ 191,600km. I asked the mechanic to measure the oil that he was draining from engine and it was exactly 4.5 litres. So electronic guage is not faulty. We put the same oil measured 6.5 litres and I checked it in instrument cluster again, it was exactly 6.5 litres. I drove the ~ 100km since then, when I checked the engine oil this morning it showed 5.9 litres of oil! I am not sure where half litre has gone, it can't consume this much oil in two days with no apparent leaks (I think).
I took the engine covers off this morning and there's no oil in air filter box or on turbo side. I changed the air filter couple of months ago and it was still clean. I did observe some gunked up oil on engine head side facing the air filter box (see pics). I have taken a couple of pictures for experts for their opinion on how to fix this issue.
Ever since I have owned this car, it was consuming oil but not that much.
Thanks in advance.
