    One of the Best Oils Available
    By  MIKE,  a  Verified Buyer  from  Tennessee  on  April 26, 2026
    Although there is no perfect oil for all applications, I believe AMSOIL is one of the very best oils available for normal consumer use. It is especially beneficial for turbo engines.

    Only oil I use!
    By  CHUCK,  a  Verified Buyer  on  April 26, 2026
    AMSOIL is the only oil I have used in everything since 2008. Lawnmowers, Harleys, and all other vehicles. About 12 years ago I bought a 2003 Toyota Sequoia that had 145k miles. First thing I did was change the oil to AMSOIL and only changed the oil every 10k miles (also used AMSOIL filters). Over the 10k intervals I may have to add a quart between changes. It now has 450k miles and the motor has never been touched!
    Bottom Line
    Yes, I would recommend this to a friend.

    WONDERFUL OIL
    By  MICHAEL,  a  Verified Buyer  from  Westminster, South Carolina   on  April 21, 2026
    This is my first time using this oil. I am extremely pleased with the results. My gas mileage has already increased by .2 mpg and I would not be surprised if this will increase a little not over time. I do not plan on using anything but AMSOIL in my vehicle. This is a high-quality product that is definitely worth the cost!
    Bottom Line
    Yes, I would recommend this to a friend.

    2017 F150 5.0 rough idle
    By  Josh,  a  Verified Buyer  from  Florida  on  March 25, 2026
    Truck would idle rough and stall out. Would crank up just fine every time and never ran rough while driving. Have read that it can be from all kinds of causes that are expensive to repair. About 1,000 miles in to this first oil change and it has not stalled out yet. In conjunction with an amsoil oil filter, WIX air filter and PI injector cleaner.
    Bottom Line
    Yes, I would recommend this to a friend.

    Reduced Ticking
    By  SCOTT,  a  Verified Buyer  from  Birmingham, AL  on  March 25, 2026
    A noticeable and immediate reduction in the ticking noise in my engine. Car has 180,000 and the noise has steady grown over the last 60,000 miles. Have 1,000 miles on the oil change and the noise is still much improved, almost gone in fact.
    Bottom Line
    Yes, I would recommend this to a friend.
