EXCELLENT WEAR PROTECTION

  • Shear-stable, high-film-strength formulation fortified with a heavy dose of zinc anti-wear additives.

    Lawn equipment small engine oil 10W-30
    By  VICTOR,  a  Verified Buyer  from  Evans GA,  on  April 04, 2025
    The 10W-30 ASEQT oil is money well spent, many of the lawn equipment I own have lasted far beyond their expected life span and far pasted the estimated life cycle posted on the durability label of operational hours. Is it the Amsoil being use? Maybe so, my 2009 Husqvarna GT52XLS lawn tractor preforms well after years of cutting my 2 acre yard, engine has great compression, and serviced; lubed points, change engine oil & filter yearly before end of winter.
    Bottom Line
    Yes, I would recommend this to a friend.

    So far so good!!!
    By  DONALD,  a  Verified Buyer  from  Alabama  on  April 03, 2025
    Installed this in a Kawasaki v-twin engine on a zero turn mower and so far the owner has reported a decrease in the amount of fuel used to cut the same acreage and the engine was consuming a slight amount but that seems to also have decreased. Definitely recommend
    Bottom Line
    Yes, I would recommend this to a friend.

    Wanted the Best For My Hard Working Yard Equipment.
    By  WAYNE,  a  Verified Buyer  from  Lloydminster, Alberta  on  March 29, 2025
    When I service my Vortex™ 3010 XP Snow Blower, 420cc, if it stops snowing, I'll be making the switch from purple to AmsOil Small Engine Oil 10W30. This after many hours spent watching test videos and reading test results and reviews. The blower works hard all season long so I want the best for it. I'll also be switching over when I service the 6.75 hp Craftsman lawnmower and the Briggs & Stratton Pressure Washer. I tend to keep my equipment for the long run so good maintenance with quality lubes is important. My only complaint, if you can call it that is that there were no AmsOil stickers in my package! Lol I'll mention this in my next order!
    Bottom Line
    Yes, I would recommend this to a friend.

    Product is fine, package is poor
    By  GRANT,  a  Verified Buyer  on  March 26, 2025
    This oil is fine but shipping/handling and packing is poor. I purchased a full case and before shipping, Amsoil shipping department labeled the box with a "this side up" note. This is a good idea but they labeled the box on the bottom so the bottles shipped upside down. When they arrived, almost all the bottles were leaking and the box was soaked in oil.
    Bottom Line
    Yes, I would recommend this to a friend.
