Sumpting
My son’s 2006 LandRover Freelander diesel seems to be getting diesel into the engine oil. We changed the oil 2 weeks ago, and the dipstick shows more oil now than after we changed it. I drained the oil and examined it for water content, but could not find any. The new oil is dirty, I would never have believed it was new if I hadn't helped Jon change it. He puts this down to the engine being diesel. My daughter in law, who does most of the driving, says the car is using a lot of fuel. It runs ok, no funny sounds, coughing, spitting, nothing like that.

If it has a diesel particulate filter and does a lot of short runs from
could this can happen. Extra diesel is injected into the engine to burn off the particulates but if the filter is too choked up this doesn't happen and the extra fuel bleeds into the crankcase. It’s vital ithat the sump oil is not allowed to rise too far otherwise there is a siphon effect and the engine will run uncontrollably on its sump oil.
