The New Hotness

  • 3-In-One Motor Oil: Mystery Inclusions

    Our new-to-us house included a heavy-duty basement dehumidifier with a blower motor calling for a few drops of SAE 20 oil twice a year. Some searching turned up a specialized flavor of 3-In-One Oil for motors.

    It arrived with free inclusions:

    3-in-One Motor Oil - top inclusion
    3-in-One Motor Oil – top inclusion

    Backlighting makes them more obvious:

    3-in-One Motor Oil - top inclusion - backlit
    3-in-One Motor Oil – top inclusion – backlit

    There’s also a free-floating jellyfish slightly denser than the oil:

    3-in-One Motor Oil - bottom inclusion - backlit
    3-in-One Motor Oil – bottom inclusion – backlit

    As is now the typical case with Amazon purchases, the only choices are to return / exchange the item, as the seller cannot be contacted directly. I tried sending 3-In-One a question through their website, en passant discovering they’ve been Borged by The WD-40 Company, only to be rejected by the site’s Captcha without ever seeing the test images.

    AFAICT, it’s oil and the motor will just have to get used to it.
