    No other product
    By  GREG,  a  Verified Buyer  from  Texas  on  February 04, 2026
    Have used email in Ram 1500 since purchased new in 2017. Have done the research on Amsoil and other synthetic products, have prices of mind that the Amsoil product is providing the best lubricators for my truck. Have also expanded to using in my jeep wranglers after I did rebuild on both of their engines. Will continue to use into the future.
    Bottom Line
    Yes, I would recommend this to a friend.

    0W-20 is an outstanding oil for both my Toyotas
    By  ANTHONY J,  a  Verified Buyer  from  Virginia Beach, VA  on  January 27, 2026
    I am being very honest here! I have been using Mobil 1 0W-20 for 12 years with zero complaints. I have used Amsoil 20W-50 in my HD motorcycle for 10 years and never used anything else. I tried the Amsoil 5W-20 signature series in my 2010 Toyota Tundra 5.7 last Spring. Below 60° I started to hear a tap tap tap noise. I never had that happen before. So I drained the oil and changed the filter after 1,000 miles!!! I switched to the Amsoil 0W-20 signature series and the taping noise was gone and never returned no matter how cold the ambient temperature was. I pull a 6X10 enclosed trailer pretty much. I contacted Amsoil and mentioned it, and asked how many miles before an oil change? The reply was 15,000 miles max. I never planed on going over 10,000 miles before an oil change, or once a year whichever comes first. I am very pleased with the Amsoil 0W-20 signature series motor oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  SCHEL,  a  Verified Buyer  from  Santa Rosa  on  January 25, 2026
    Best oil you can buy. I used it many years ago. I’m back as a customer. I didn’t like not being able to buy it in a store when I needed it. I will say their delivery service is fast and good. Not a problem getting oil.

    My experience with Amsoil products
    By  PAUL,  a  Verified Buyer  from  NC USA  on  January 23, 2026
    I have been using Amsoil products for well over 25 years. During that time I have had many different vehicles of all brands that I have used Amsoil in the crankcase, transmission, rear end and transfer cases. all have been good vehicles with no problems at all with lubricated parts. The 2 I am most proud of though are the 2 Dodge Dakotas I owned that I put over 280,000 miles on and only changed the oil and filter every 20.000 miles. Also maintained the other lubricated areas at 50,000 mile intervals and both still ran as strong as when I bought them new! You just can not go wrong with the Amsoil brand of products for ALL your cars or trucks needs.
    Bottom Line
    Yes, I would recommend this to a friend.
