About this item

  • Extended-drain lubricant engineered to last longer and protect gears better than conventional gear oils. Reduces wear, conditions seals and helps prevent rust. Promotes longer equipment life and reduced maintenance costs.

    See the Product Data Bulletin for full details.

    PROVIDES LONG SERVICE LIFE

    • Engineered for extended drain intervals up to 500,000 miles (805,000 km) as set by equipment manufacturers for over-the-road trucks and heavy equipment.
    • 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.
    • Recommended for (not limited to) over-the-road trucks; light-, medium- and heavy-duty trucks; off-road equipment; commercial vehicles; motor homes; autos; SUVs; emergency vehicles; buses; delivery/utility vehicles and tractors.
