PROVIDES LONG SERVICE LIFE

  • Provides long life in passenger cars and trucks.
  • Lasts several times longer than conventional lubricants for less maintenance and increased convenience.

FIGHTS GEAR & BEARING WEAR

  • Shear-stable formulation resists viscosity loss from mechanical activity for maximum gear and bearing protection.
  • Forms a durable protective film between metal components to guard against metal-to-metal contact.
  • Premium synthetic base oils and additives resist chemical breakdown for long-lasting protection.

INCREASES EFFICIENCY & CONVENIENCE

  • Provides improved cold-temperature fluidity compared to conventional lubricants, which reduces energy lost to friction and maximizes fuel economy.
  • Resists acids to maintain cleanliness and efficiency.
  • Superior cold-temperature fluidity and high-temperature stability make AMSOIL Long Life Synthetic Gear Lube excellent for all-season use.

    Poor Shifting in Cold Weather
    By  Wildman,  a  Verified Buyer  from  Reno, NV  on  May 12, 2018

    Describe the issue

    I replaced the OEM oil in the manual transmission on a 2014 Subaru Outback at about 60K miles. In the cold weather it was difficult shifting from neutral to first and first to second gears when cold. Shifting improved when the temperature increased after driving several miles. Therefore, I cannot recommend this lubricant for the stated application.
    Bottom Line
    No, I would not recommend this to a friend.
