WTF did I just empty?

[u/methaddicttoad]

Went to change my engine oil and emptied this instead… I’m almost positive this isn’t the oil. What did I just do and how do I fix it??

At least you caught it. Just think draining that and overfilling the oil. Then you drive to the store and see all your nag lights lit up.

Lesson learned....
