Air compressor acting funny, what gives?!

Yea I always made sure to keep it oiled, and would change it out every couple months. I would use the recommended kobalt brand as well.

Yea I would drain it out after use. Not gonna lie... There been a few times I have forgotten until the next day. Just a few times though....

What would cause the lack of lube? Always made sure it was at level.

So it's the pump that could possibly be bad? Vs the motor?

I could have recalled hearing some sort of knocking coming from the pump as well. The last 30min before I shut it down completely.
