I believe that this is not as big a worry as people suggest. Replacing a small proportion of the oil (up to about 3%) with diesel as Volvo suggest as an interim solution is not outrageous in my opinion. In any case, they will probably come up with a better solution in due course. In my case the software seems to have "fixed" the rising oil level problem.

Diesel has some lubricating properties similar to WD40. Diesel engines have always had some blow-by that contaminates the oil with diesel. Despite this diesel engines have traditionally had a life expectancy much better than petrol engines. Petrol engines have blow-by that contaminated the oil with petrol, that has no lubricating properties whatsoever.

Who intends to drive their diesel XC60 for more than 400,000 miles?
