Oil dilution problems on Focus 2017 Mk 3.5 1.5 litre durotorq 120 bhp engine

[Agile]

A friend of mine has this problem on his car.

He thinks it is a common problem on his model.

He thinks that it is related to the car's automatic procedure for cleaning the particulate filter!

But I am rather sceptical about this as there seems to be little information available on the internet.

Does anyone here have any strong views on this problem ?

If indeed this engine does use excess diesel to regenerate the DPF then it is a particularly bad thing, and has caused the demise of many a good motor....Mitsubishi and Mazda in my experience!
Diesel is an excellent solvent but a hopeless lubricant.
I'd be contacting Ford concerning this one, just to see if it uses this system.

Your friend is right. The emission system tries to heat up the DPF by injecting excess fuel into the engine, some of which makes its way past the piston rings into the oil. If the engine continually fails its regen cycle then it keeps trying and you end up with diluted engine oil.

If you don't then change the oil you can end up with the engine running on it own oil and it self destructs.
