Thoughts on these bubbles in bottom of oil drain pan?

Possibly too much oil? Dip stick has been hard to read historically

 

Looks like an incompatible fluid, such as water or ethylene glycol.

 

Do you think it requires further analysis if engine seems to be running fine?

 

depends on age, mileage, and drive cycles.

lots of short trips will build up moisture in the motor oil.

 

Sitting at 73k on a 2015 4.0. I do make a lot of small trips. Thank you for replies

 

Short trips are the worst thing for an engine. You need to get the engine up to full running temp to evaporate off moisture that collects. Getting up to full temp will also benefit your catalytic converters too.
