    Commercial use
    By  SCOTT,  a  Verified Buyer  from  Alabama  on  September 22, 2022
    I use this in my commercial mowers. Hundreds of ours so far. I personally would not go over 100 hours on any oil unless you have a separate oil resuvuir. All in all, this oil takes a beating and has I think made up the difference in price from cheaper oils.
    Bottom Line
    Yes, I would recommend this to a friend.

    Small Engine SAE 10-40
    By  REX,  a  Verified Buyer  on  June 24, 2022
    I've been using Amsoil products for years and have not been disappointed with their performance. My JD 318 and now Kubota Z422 use Small Engine Oil. I think this oil has permitted the JD 318 to operate without a mechanical issue, even under some hard use. Since the Kubota is new it should last for years to come.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best small engine oil
    By  ALEX,  a  Verified Buyer  from  GA  on  November 19, 2021
    I have run this oil for years in all of my commercial mowers. I have multiple with 1000’s of hours and have yet to have an engine failure. They get worked hard and the oil is still clean looking on the majority of them! Great product!

    Great oil, but that's about all Amsoil has to offer
    By  LEE,  a  Verified Buyer  from  Dawson Pa  on  October 30, 2021
    Their oil is really good, but they don't offer anything else for Zero Turn Mowers. No oil filters etc.. I don't know why, it's a big market they are missing out on.
    Bottom Line
    Yes, I would recommend this to a friend.

    Extra Engine protection
    By  PAUL,  a  Verified Buyer  on  October 10, 2021
    I am a long time Amsoil user. This is my first time using the commercial grade because my local retailer didn't offer it. I use it in all of my yard equipment because of the extra zinc and the added anti-wear protection it offers.
    Bottom Line
    Yes, I would recommend this to a friend.
