    High mileage oil test
    By  Scott,  a  Verified Buyer  from  North Carolina  on  November 28, 2023
    Testing the high mileage oil out on my wife’s car. Used all different brands of high mileage in my wife’s 1997 civic with 363,000 miles. So far so good. But I use amsoil in my other cars so I have no doubt it will help her car last longer
    Bottom Line
    Yes, I would recommend this to a friend.

    Unbelievable
    By  WILLIAM,  a  Verified Buyer  from  Eatonton Ga  on  November 22, 2023
    First time using a high mileage oil in my 95 YJ Jeep. My 2.5 has +193,000 miles and the Amsoil has been amazing in respect to increasing gas mileage, more pep and just better sound. I have used Amsoil for over 2 years but this high mileage oil takes my Jeep to a new level. I look forward to having the oil tested at 12,000 miles. The signature 5w-30 was good as gold at 17,000.
    Bottom Line
    Yes, I would recommend this to a friend.

    High Mileage For, Well, High Mileage.....
    By  Thumper,  a  Verified Buyer  from  Sanford, Fl  on  October 26, 2023
    I have a 2003 Ford 4.2L V-6 work van that I ran out of coolant after blowing a lower hose on the highway and not knowing about it until it began knocking and seizing up. I called a ride and went and got some coolant and a hose, changed it out and drove almost a hundred miles to my home. That was at 160k miles. I had Amsoil Signature series 5W30 in it then, and I credit the fact that it is still running flawlessly today with 225k miles on it to that fact. Now, in its advanced age, I use High Mileage 5W30, and still drive that van all over the state for work. You need to use Amsoil. Seriously, use it......
    Bottom Line
    Yes, I would recommend this to a friend.

    For an oil burning engine, this is a life saver
    By  Bob,  a  Verified Buyer  from  California   on  October 25, 2023
    I was skeptical of this despite using Signature Series and still having oil burning issues that improved initially and then got worse. After using this product and checking the oil weekly, it’s dramatically slowed down the oil burning. I will continue to to monitor and keep an eye out on the oil levels to make sure there’s oil inside the engine. So far, impressive. Time will tell.
    Bottom Line
    Yes, I would recommend this to a friend.
