    Superior lubricant
    By  GREG,  a  Verified Buyer  from  South Carolina   on  November 01, 2021
    I have Ben using Amsoil in all my vehicles and equipment since 2007. I have never had any engine problems or mechanical issues what so ever. I’ve studied the index test and believe they are correct. Amsoil is the premier lubricant available today.
    Bottom Line
    Yes, I would recommend this to a friend.

    Have had great results in longevity of my motor
    By  JOE,  a  Verified Buyer  from  Calgary Alberta  on  November 01, 2021
    I have only old vehicles that I drive my newest vehicle is my 2004 Durango with 5.7 l engine, I also have a 2003 Jeep Grande Cherokee that my son now drives and a 1999 Jeep Cherokee and a 2001 jeep Cherokee that my wife drives. I also have a one lap of America 1969 340 race car and an 1985 Omni GLH stage 2 race car, and a 1973 Austin Mini for vintage racing. All have a lot of miles. The Durango and 2003 Jeep have over 300,000 on them and the 2001 has about 150,000 miles, they are still running strong and no oil burning is going on at all. We have had great results and will always use Amsoil in our vehicles. Thanks

    Only the best will do!
    By  DARREL,  a  Verified Buyer  from  Melrose, Wi  on  October 30, 2021
    In my opinion when a person spends their hard earned money to have nice equipment why sacrifice it all by using cheap, unreliable lubricants to keep everything running smooth! Only choose the best Use Amsoil.

    Not enough to accommodate for my engine
    By  EDGARDO,  a  Verified Buyer  from  West Warren  on  October 30, 2021
    The product is very good, my only issue is the fact that I need to make two purchases to accommodate correct oil level. It would be good to have the correct amount to fill engine's to their proper level.
    Bottom Line
    Yes, I would recommend this to a friend.

    Shipping handling
    By  BRANDON,  a  Verified Buyer  on  October 29, 2021
    Ordered 5 qts, they arrived in a 1 gallon container and a 1 quart container. The quart broke open and filled the plastic bag they were tied in. No other packing material was used.

    First time customer
    By  Zack,  a  Verified Buyer  from  Kingsport, TN  on  October 29, 2021
    This is my first time using an Amsoil product and I bought 12qts of 0W-20 for my 2016 Camry XLE 2.5L. Why, because Walmart quit selling 0W-20 Pennzoil platinum full synthetic in the 5qt jugs at my stores. I decided to finally try Amsoil, I've put almost 2k miles on my Amsoil oil change and so far the smell, and color are looking good compared to any other oils I have used thus far with 2k miles on them. Mobil 1, Pennzoil, and Valvoline are the ones I have used, all full synthetic, not that semi-synthetic stuff either. I will change my OEM canister filter out when I hit 5k, and once I hit 10K with this oil I will be sending a sample in to get it tested and see how well it is working.
    Bottom Line
    Yes, I would recommend this to a friend.

    It’s the first time I’ve ever used this oil, but I feel confident in its abilities to protect my engine. This is solely based on the reviews and the company’s reputation. It’s been about a month since I changed my oil. No problems so far. Highly satisfied and recommended.

    Great oil
    By  CLINT,  a  Verified Buyer  from  IL  on  October 27, 2021
    I have used Amsoil for 20+ years. My vehicle blew an oil line (9/28/2021)while my wife was driving it and all the oil leaked out. I was worried the motor was ruined but after repairs made and filled back up with Amsoil, there was as no problems. I attribute this to the quality of Amsoil. Thanks for making a quality oil!!!
    Bottom Line
    Yes, I would recommend this to a friend.
