Can paper towels soaked in canola oil spontaneously combust?

I recently purchased an outdoor flat top gas grill (Blackstone 36 inch 4 burner) griddle station.
I seasoned it correctly so the flat top is a nice black color. Before and after every use I get the surface hot and wipe it with canola oil and several paper towels. When I am cooking, I wipe it several times with paper towels and throw them in a trash can I keep next to the unit. It occurred to me that there might be the potential for the “oily rags” spontaneous combustion we all learned about in school. (I believe that was right after the quicksand lesson.)
Is there any chance of spontaneous combustion with canola oil and paper towels?
There are plenty of examples of SC with linseed oil and cloth rags but I see nothing about cooking oil and paper towels.
Do I need to worry?
