EXCELS IN TEMPERATURE EXTREMES

  • Delivers excellent performance in hot and cold temperature extremes.
  • Resists breakdown from high heat, preventing acids and carbon/varnish formation.
  • Wax-free construction improves cold-flow properties, improving fuel economy and cold-weather shifting.

MAXIMUM WEAR PROTECTION

  • Specifically engineered for maximum performance in severe-duty applications.
  • Maintains viscosity for long-lasting protection against metal-to-metal contact.
  • Proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring.
  • Helps prevent "thermal runaway," a phenomenon caused by a lubricant’s inability to control friction and increased heat under high-stress conditions.
  • Inhibits rapid lubricant degradation and component damage, helping equipment run better and last longer.

    Oil supposed to be good, but I have mixed feelings
    By  VLAD,  a  Verified Buyer  from  NJ  on  February 13, 2024
    Reporting facts, you decide. Used AMSOIL 75W90 for gear oil change. Changed original factory fill toyota highlander oil in transfer case and differential at 60k miles. Did it on warm gear boxes just after the trip to make sure it would fully drain and particles (if any) are suspended. Magnets on oil plugs contained some shavings, but oil looked pretty clean and clear. After a months and about 200 miles I had a reason to drain this oil in the same manner. To my surprise oil contained metal silvery particles in it and looked a bit different than it was when new just a month ago. Magnets on both plugs again contained metal particles, but very little compared to first time. Wiped with napkin and it did show black traces of metals. At this point I am not sure what to think of the reasons for oil/magnets to contain wear out materials at such a low miles.
    Bottom Line
    Yes, I would recommend this to a friend.
