    Great Product

    Great product
    By  BG,  a  Verified Buyer  from  Texas City, Texas  on  May 22, 2017
    Amsoil is a great oil. I personally change oil in 8 automobiles and light trucks. Also 1 motorcycle and two lawnmowers. My highest mileage is 200250 miles. I can tell you that Amsoil and their filters will do a superior job. The only down side is the shipping charges. Amsoil is priced about the same as Mobile 1, but the charges mean you pay top dollar.
    Bottom Line
    Yes, I would recommend this to a friend.

    I use it in conjunction with the Amsoil bypass filter. Usually Change oil after 20,000 miles or so. It's great oil, as is your trans and differential oil.

    Great Long Lasting Oil
    By  Jason,  a  Verified Buyer  from  Vista  on  April 18, 2017
    I have changed all fluids to AMSOIL. The oil viscosity is superior to any on the market. I do the recommended oil change to may 2500HD Duramax. Even after a 10,000 mile oil change the lubrication in the oil is still as if it were brand new. AMSOIL is the best to run in any motor. Give it a shot you have nothing to loose with using AMSOIL products.
    Bottom Line
    Yes, I would recommend this to a friend.
