Oil in air drier filter

[tree98]

Yea the guys on here told me to change them before winter each year. I took mine apart because my air lines were freezing up. I put a piece of cardboard over the braided line that goes into the dryer from the compressor and ran it for a few minutes to see if there was oil on the cardboard. That would tell you if your compressor is losing oil into the air system. Mine wasn't so I'm guessing the goop was accumulated over years. In your case being only 2 years old you might want to dig a little deeper. I'm surprised your tanks are dry though.
