    Best small engine oil out there!!
    By  RYAN,  a  Verified Buyer  from  Lookout mountain Georgia   on  March 16, 2026
    Use this product universally in all small engines from the four wheeler zero turn tiller pressure washers welding machine or generators with excellent results. Unlike conventional products offered for above equipment the amsoil stays clean longer-term and the engines run smoother. Also noticed a big difference in shift quality on four wheeler and tiller. No doubt they make atv products that are even better but I can stock this and cover all small engine service.
    Bottom Line
    Yes, I would recommend this to a friend.

    Dependable small engine lubricant
    By  KENNETH L,  a  Verified Buyer  from  Northwestern area of PA  on  February 18, 2026
    I have been using this oil in my walk behind mower for 25 years and this craftsman mower is still doing the task that it was designed to do. Change the oil and air filter once a year, sharpen the blade, and clean debris away from around engine and you'll have no problems.
    Bottom Line
    Yes, I would recommend this to a friend.

    Product review
    By  Jim ,  a  Verified Buyer  from  568 SW Chapel Hill  on  January 14, 2026
    Product is good, shipping is great and timely. My gripe is the teaser give away deal. I'm probably buying the Product anyway so doesn't really matter. Don't tell me there's a freeby,but I probably won't remember to jump through the right hoop at the end. When the Product gets to without the click bait, give a me reason to believe I've been scammed.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great oil for my generators
    By  DAL,  a  Verified Buyer  from  North Carolina   on  November 23, 2025
    I have 3 generators of various sizes. Start up from 0 to 3600 rpm is always nerve racking thinking about the wear going on during start up. I am confident this oil is providing the best protection possible.

    Yes, I would recommend this to a friend.

    I needed 10w-30 synthetic oil for my old Kohler mower engine
    By  LARRY,  a  Verified Buyer  from  KC Mo  on  November 19, 2025
    The lawn mower dealers and repair shops did not have what my mower engine calls for 10w-30 synthetic oil. I do not know why. They wanted me to put some heavier oil that they had 10w-40 I said no and ordered Amsoil . Plus oil and filter kits for my 2 cars.
    Bottom Line
    Yes, I would recommend this to a friend.
