It's rare, but can happen. Have a sample tested for fuel contamination.

What brand/grade of oil?

Try another brand of oil. Synthetic would be a significant turn-around. If it doesn't improve, you may have a real problem. 2l in 5K is about double what may be acceptable.

When it comes to oil for your engine that is the very last place to cheap out-definatly get away from the CTC stuff and go with Shell,Valvoline or Kendall oil or synthetic.
Kendall is my favorite but many folks like the Shell Rotella oil for diesels.
