What is the cause of diesel fuel in crankcase oil?

In the specific case of diesel cars, diesel fuel also enters the crankcase as a result of post-injection during regeneration so that the fuel gases can reach the crankcase and help the regeneration process by providing heat. As not all diesel fuel turns to gas, part of the fuel enters the crankcase, which produces the dreaded oil dilution.
