    Best oil you can buy
    By  BRETT,  a  Verified Buyer  from  South carolina  on  November 05, 2023
    Put this in my wife’s jeep and no more lifter noise. This is worth it, it doesn’t matter what it cost, if it keeps the motor running longer it is worth it.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  HOWARD,  a  Verified Buyer  from  Montreal, Canada  on  November 04, 2023
    I've been using only Amsoil in my cars since 2000 because it's the best. Nothing more to say!

    Extended drain
    By  MIKE,  a  Verified Buyer  from  Southeast Wisconsin  on  November 04, 2023
    Based on testing and personal experience, this is the best oil on the market. I love that I only have to do two oil changes a year given the high miles one of our vehicles is driven each year. Our other cars go a year between oil changes.
    Bottom Line
    Yes, I would recommend this to a friend.

    Long life is the key to getting a bargain out of this oil. s
    By  keneke006,  a  Verified Buyer  from  WA  on  November 02, 2023
    I really like this oil and wouldn't put anything else into my engines. Add some militech or best oil(?) and get the most out of a refill. Just be sure not to let it run too long otherwise the oil thickens as it ages. Well, it did in my 454SS Chevy truck running a heavier viscosity oil so take that with a grain of salt. Other than that it is a good buy.
    Bottom Line
    Yes, I would recommend this to a friend.

    NO Better Synthetic to use!!!
    By  Christopher,  a  Verified Buyer  from  Florida  on  November 01, 2023
    My three automobiles all take 0W-20 Signature Series Synthetic Oil. I am shocked that all of my oil changes are unbelievable! Each time I have drained the oil, I could still see the life left in the oil. I change all of my oil at 10k, on the dot every time. There is not better oil to use!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Top tier
    By  DAVID,  a  Verified Buyer  from  Apsley, Ontario  on  October 30, 2023
    I believe that this is the best oil you can buy. You can tell how long it lasts in most engines by keeping an eye on the oil level, generally as the oil breaks down and becomes contaminated your engine will start to consume oil, that's when it's time to change it, so keep an eye on it especially when the mileage is over 10000 km's and change it when you start to see any sign of consumption, this varies with every vehicle. The oil is so good that you will notice your engine runs smoother and fuel economy and performance is maximized, I love this oil so much that it's not worth my time and effort to install anything else, Also use the Amsoil oil filter for extended oil drain intervals.
    Bottom Line
    Yes, I would recommend this to a friend.

    The best results
    By  LARRY,  a  Verified Buyer  from  Leesburg VA  on  October 29, 2023
    I use AMSOIL in all my vehicles and noticed better performance, gas millage, and my engines run cooler. Keep in mind when ordering the large jug is 4 qts. This product is the best for what you get.
    Bottom Line
    Yes, I would recommend this to a friend.
