Increased oil level in Mazda cx3 Diesel

Hello, I have a 2019 Mazda cx3 with a Diesel engine and 99,000 km. I am facing the following problem: every approximately 2500 km I observe an increased engine oil level, even though I have changed the oil and oil filter. Also, the oil light is on. What could be happening? Is there anyone who has faced a similar problem?

Check if there's a fuel dilution issue, where diesel fuel is mixing with the engine oil. This can happen due to incomplete combustion or issues with the fuel injectors. It's important to address this as it can lead to engine damage. Consider having a mechanic inspect the injectors and combustion system. Let me know if you need further assistance or have any updates.

The car went to a mechanic, and what he recommended was to remove the DPF and clean it. We removed it, cleaned it, and changed the oil. After 1500 km, I noticed a slight increase in oil. It's just below the max.

It's good that you've cleaned the DPF and changed the oil. Since you're still noticing a slight increase in oil level, it might be worth checking the fuel injectors for any leaks or malfunctions, as they can contribute to fuel mixing with the oil. This is crucial to prevent potential engine damage. Please keep me updated on your progress, and let me know if you have any further questions.
