    By  DON,  a  Verified Buyer  from  Goderich   on  August 20, 2026
    Amsoil synthetic 0W20 is the best oil iI have ever used. My first break in oil change was fantastic with virtually no metal on the magnetic drain plug and filter. I have changed it again at 3000 kilometers with the same result. Highly fecomended as a kit with WIX filter.

    So far so good
    By  SAMUEL,  a  Verified Buyer  from  NW Connecticut  on  August 18, 2026
    Jeep engine seems to run smoother & quieter than before. Wll probably change @ 15K instead of pushing it to 25K. Definitely beats changing oil in December, January or February

    Best Oil I have used!
    By  BRAD,  a  Verified Buyer  from  Northern Michigan  on  August 18, 2026
    I have used Amsoil products for well over 2 decades and in many different vehicles. They always perform extremely well and are unmatched in their field for providing the best protection for their various uses. I generally buy previously-owned vehicles and use Amsoil from that point forward. It provides longer life for the vehicle and I have a much lower incidence of the need for engine repair.
    Bottom Line
    Yes, I would recommend this to a friend.

    Don't pass up
    By  MR10K,  a  Verified Buyer  from  INDY  on  August 18, 2026
    If your wondering or undecided purchase the product the fits/works with your vehicle it'll be awesome decision. I was told from Jeffy Lude years back that oil doesn't matter LIES. One oil change with AMSOIL will make you wanna slap yo pappy. I've used it on a GMC TERRAIN AND CHRYSLER PACIFICA both notice instance changes in performance my God. I'll never use another brand oil. We'll only in emergency situations. If you purchase the oil but don't install yourself Jeffy will use your own oil if you ask i do it all the time there when I'm feeling lazy.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best decision
    By  KRISTIN,  a  Verified Buyer  from  Kansas City  on  August 17, 2026
    I started using this oil just recently and was introduced to it by a coworker. This oil is hands down the best decision I’ve made for maintaining my truck. This product has tremendously improved my gas mileage, and my truck runs so much better. I will be a returning customer for as long as I own vehicles. If you’re on the fence, just do it. You won’t regret the decision. I even started using the oil in my lawn equipment!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Unsurpassed excellence
    By  Andy,  a  Verified Buyer  from  Northern VA  on  August 16, 2026
    I am a user of Amsoil products for over 20 years and they always surpass my expectations. Increased mileage and reduced wear. I have no problems running my cars over 150,000 miles without having any mechanical problems. They provide a tremendous return on my investment. Not interested in using any other brand of lubricants for any of my gas powered equipment.
    Bottom Line
    Yes, I would recommend this to a friend.
