    If you have not heard of Project Farm on YouTube, he does comparison tests of tools, car stuff, and random other stuff (trash bags, battery banks, insulated tumblers, etc)

    He just posted a video today of testing various OEM 0W-20 vs Mobil 1 0W-20.
    Motor Oils: Mopar, Motorcraft, ACDelco, Honda, Toyota, and Mobil 1. Motor oils compared for lubricity or film strength, evaporative loss, and cold oil flow before and after heat exposure.

    Some takeaways:
    • It looks like Toyota oil does flow better after being heated (used) and then frozen to -40F, this is good for cold starts in the frozen winters.
    • Toyota and Mobil 1 do have less "detergents" compared to Honda/GM/Ford/Mopar
    • Toyota has the lowest anti-wear additives at about 1300ppm. The rest were all between 1600 and 1700ppm
    • Toyota had the lowest TBN (Total Base Number)
    Just the first half of the video has the oil comparison. It's an interesting watch:
