Gas in oil pan
 

I’m experiencing quite a lot of fuel in my oil not too sure where it’s coming from or what could be causing it. There’s a small square that appears to be filled with fuel and I’m not sure what it does or is. I’m new to this wonder if some had an answer.

Little black square in center is fuel.
