    Best you can buy
    By  BLAKE,  a  Verified Buyer  on  September 16, 2023
    I've been using AmsOil products for 30 years. It's by far the best synthetic you can buy. They always are improving the products and keeping up with market trends and new technology.

    Noticeable Difference Right Away
    By  TIM,  a  Verified Buyer  from  Jamestown, ND  on  September 11, 2023
    I have been a fan of this oil for years. After switching from OEM oil to this oil it seems as if my valve train was quieter and the motor is just smoother while running. With the price of new vehicles these days taking care of what you have is a high priority. This oil delivers on all fronts. Great product.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best I have ever used
    By  MICHAEL,  a  Verified Buyer  from  San Diego County  on  September 07, 2023
    I have been using synthetic motor oils for over 2 decades. I KNOW they are superior. I have seen engine teardowns after the use of synthetics and the difference between a quality synthetic user and not is striking. I switched, permanently, from the biggest named synthetic brand to Amsoil. I know some of the top builders swear by Amsoil, and when I heard someone speak of an increase in operating temp oil pressure I gave it a try. My vehicle with a brand new early 90's OHV push rod V8 gained FIVE FULL POUNDS of oil pressure at idle and operating temp. I was blown away. With the superior protection of synthetic, the lubricity of Amsoil, I am totally sold. I recommend Amsoil to anyone that wants to get the maximum out of their engines.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best of the best
    By  ROBERT,  a  Verified Buyer  from  Ontario, Canada  on  September 07, 2023
    I have been an Amsoil user for 15 years, so when I bought my new Mustang GT it was a simple choice to go with Signature series 5W20. There is quite simply no better oil at any price. There are others with gimmicks and dyes and wild claims but, if you look at the evidence, the choice is clear.
    Bottom Line
    Yes, I would recommend this to a friend.

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

    Best engine oil in the business
    By  DONALD,  a  Verified Buyer  from  Pickens, South Carolina   on  September 05, 2023
    I tell you that I did not just believe what a company ad or just like look a t a pretty Package I talked to people for years individual and dealers who use the products. If I was poor then you get what you can afford to get the job done. But if your smart and you research and do your calculations, you can see the value in a premium product. And you research what other oil MFG's get to use to classify a conventional oil as a synthetic!
    Bottom Line
    Yes, I would recommend this to a friend.

    5-30 Signature series oil
    By  Robert,  a  Verified Buyer  from  Southern California  on  September 02, 2023
    This is truly a great oil. I change my 2020 Ford Raptor oil every 5,000 miles and it is virtually negative on all wear particles per the oil analysis I send in. My only gripe about this oil is that it is far too expensive now days! Inflation is one thing but you have raised the price far more than seems necessary.
    Bottom Line
    Yes, I would recommend this to a friend.
