Doubt it’s a problem if it is just the oil level. I’ve driven my XC70 a good few miles with that problem.
I’m told it can also happen when the DPF regenerates and dumps fuel in the sump. Sounds odd to me but I’m not a mechanic!
There are other threads on this issue, if you search for “Engine System Service” you should find something.
