    Great oil
    By  PAUL,  a  Verified Buyer  on  October 19, 2026
    When I bought my new to me 2008 Honda Element EX, it had 165,000 miles. The owner described vtec problems and 'the code'. I changed the screen behind the solenoid valve and at the same time switched to Amsoil Signature Series 5w-20 and filter. Since then the vtec issues haven't come back even though the oil change intervals have been 15k yearly. Now at 256,000 miles it still runs great!
    Bottom Line
    Yes, I would recommend this to a friend.

    Supercharged F150 5.0
    By  DAVE,  a  Verified Buyer  from  Illnois  on  October 19, 2026
    Been Running 5w50 Signature since my second oil change. Previously ran Motorcraft 5w50 synthetic but it dropped out of grade between changes. Both Whipple and Ford require 5w50 in supercharged 5.0 platforms. This is a daily driver with short trips on weekdays. Oil analyzed at every change with very low wear metals. Change oil and filter @ 5K, this oil stays in grade.
    Bottom Line
    Yes, I would recommend this to a friend.

    Bottom Line
    Yes, I would recommend this to a friend.

    Oil
    By  BRYAN,  a  Verified Buyer  from  Pennsylvania  on  October 18, 2026
    Oil was fine, but the multiple containers seems a bit redundant.

    Best Engine oil Ever

    I've been using Amsoil signature series for quite sometime. Nothing close to the quality and performance of Amsoil.

    SIGNATURE
    By  WILLIAM,  a  Verified Buyer  from  Oregon   on  October 17, 2026
    I prefer the Signature 0w20 oil in my 2020 Honda Accord Hybrid and my son’s 2022 Honda Odyssey since both vehicles often take very short trips in the Autumn and Winter. I’m confident the engines are getting the best possible protection.
    Bottom Line
    Yes, I would recommend this to a friend.

    2020 Dodge Challenger RT
    By  DARRYL,  a  Verified Buyer  on  October 13, 2026
    I have tried several other oils from all the top brands available. Hemi engines are well known for knocks and ticks. If you want to eliminate those issues. Use AMSOIL. 100% best engine oil on the market. Eliminates all of the engine noises and definitely outperforms all other oil competitors.
    Bottom Line
    Yes, I would recommend this to a friend.

    Oil that delivers protection
    By  HipHip,  a  Verified Buyer  from  Chicago   on  October 12, 2026
    I’ve used other brand oils on the vehicle and what happens is after 1,000 miles I have to add about a quart. I use this product and it delivers protection needed that after 2,000 miles I only need to top off 1/4. It’s good stuff, order your oil today.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil for mustangs
    By  BOBBY,  a  Verified Buyer  from  Forest city  on  October 12, 2026
    This is the best oil you can put in your mustang, V8, v6, ecoboost doesn't matter. The premium oil holds up for so long and you dont feel that horsepower loss when your oil tends to break down. This oil is the best. I've used it in motosports and now my daily mustang.
    Bottom Line
    Yes, I would recommend this to a friend.

    A very quiet GM 6.2!
    By  BRADLEY,  a  Verified Buyer  from  Bakersfield   on  October 11, 2026
    After the first freebie oil change, I switched to the Signature Series! I change the oil and filter when the algorithm hits 50%.
    Bottom Line
    Yes, I would recommend this to a friend.
