    Best oil
    By  LARRY,  a  Verified Buyer  from  Alabama  on  November 01, 2026
    Best oil ever for my Toyota specifying 10,000 mile oil changes. I tested the Amsoil oil in it with an analyzer and it showed my oil life still had 20% life left with 12,000 miles on it. I decided to change the oil at 13,000 miles and tested the oil and it showed oil life at greater than 15% oil life left. Very pleased I can extend my change interval from 10,000 miles with confidence. Use Amsoil products in all my vehicles and equipment as it is the best out there.
    Bottom Line
    Yes, I would recommend this to a friend.

    AMSOIL MOTOR OIL
    By  JOSE,  a  Verified Buyer  from  PA  on  October 29, 2026
    This is amazing stuff, First time user and never coming back. The first time was 80k and I thought started out with Amsoil High-mileage 5w30. After around 3-5 miles I notice that my engine was quite, really quite, so I took it on the highway, afterword's I was in shocked. I revved it up to 5.7k RPMs, spirited drive and I had to slow down. I don't have any leaks or burning oil but I thought I should tell you all that shear my experience. I'm changing to Amsoil Signature after 85k. Also changed Amsoil fluids, front/rear diff and brake fluid, next time I well change transmission fluid and transfer case fluid. 2020 EXPLORER ST
    Bottom Line
    Yes, I would recommend this to a friend.

    Only the best for our vehicles.
    By  WAYNE,  a  Verified Buyer  from  Lloydminster, Alberta  on  October 28, 2026
    This order was for our 2017 KIA Soul EX 2.0 li. Because some of these engines are prone to internal issues, I sought out the best lubrication that I could find. After hours of videos, podcasts and independent test results, Amsoil came out on top by a hefty margin. We switched our 2018 Dodge Grand Caravan Crew Plus over to Amsoil first. A noticeable reduction in start up noise. We noticed the same when we switched the Kia over to Amsoil. I track my fuel mileage on both vehicles. The Kia is primarily used in town, the Dodge is our highway go to. After a very short time, I found our fuel consumption on a highway trip dropped by a steady 1 li/100 kms.. Found the same reduction on the Kia when we ran a long run. I run magnetic oil pan plugs in both vehicles. Both plugs are free of metal traces when pulled for servicing. Yes, Amsoil costs more. But by using both the oil and filters, I think it will payback in engine life. The Kia, because it runs short trips mainly, gets serviced at 7,000 kms. The Dodge at 15,000 kms of highway running. Both vehicles are in a heated garage which makes for warm easy starts when it's -40c outside. I have no plans for trading either vehicle in anytime soon, so I look after them. Amsoil helps me do just that.,
    Bottom Line
    Yes, I would recommend this to a friend.

    New customer just started using it.
    By  PHIL,  a  Verified Buyer  on  October 28, 2026
    I bought 5w-30 signature series because we recently purchased a 2026 Lincoln Aviator with the 3.0 twin turbos. I wanted according to everyone the best synthetic oil i could put in there for protection. My Lincoln only had 2,400 miles on her when I changed over to AmsOil and WIX oil filter. Time will tell.
