It really is and begs the question how manufacturers were allowed to build so many diesels over the last 15-20 years.

My next car will not be a diesel, it is just filthy. I changed the oil in mine last month and within about 10 miles, after checking the oil level via dipstick, the oil was black again. 2 years ago, I removed the swirl flaps, cleaned the intake manifold and the EGR valve and although it wasn't as bad as above, the amount of carbon that came out and this was a car that spent 90% of its life on a motorway.
