    The best oil!
    By  KENNETH,  a  Verified Buyer  from  Celina, Ohio  on  July 27, 2022
    No oil can compare to Amsoil. I don't cheap out when it comes to what I put in my Lexus. Everything runs so smooth, and feel great knowing my engine is protected using Amsoil. Price is worth, the quality and protection.
    Bottom Line
    Yes, I would recommend this to a friend.

    Smoother & Quieter
    By  JEFFREY,  a  Verified Buyer  from  Youngsville, NC  on  July 27, 2022
    Since I switched from Mobil 1 to Amsoil I have noticed that my vehicles run smoother and quieter. It has to be because of the superior oil adherence and lubricity.
    Bottom Line
    Yes, I would recommend this to a friend.

    Sig Series Syn
    By  BIG MIKE,  a  Verified Buyer  from  Ohio  on  July 24, 2022
    Awesome product. Switched my Vette to Amsoil after watching my buddy race his for 2 years without any issues. Superior protection, runs smoother and cooler. Looks cleaner than Mobil 1 after 5k miles. So impressed I switched both my Colorado 4x4 and the Traverse AWD HighCountry to Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great Oil But Extremely Costly!!!
    By  KENNYD,  a  Verified Buyer  from  San Jose California.   on  July 24, 2022
    Been using Amsoil now since 1997. In Everything We Own. It is getting to the Point now that Some other Brands are going to be getting poured into our Vehicles Due Simply to AMSOIL’S PRICING Strategy which is running me and my Customers Elsewhere. This is Quite discouraging because I really like the product. But at $12/13 PER QUART, It’s not cost effective for me to continue down this Path when there are some other Full Synthetic Oils out there that have proven themselves quite worthy at 1/2 the Price. That said. Amsoil is a Great Product and a fantastic lubricant!!! No other complaints from here. Just the Price. It’s outta control!!! Thanks SLEEPY JOE!
    Bottom Line
    Yes, I would recommend this to a friend.

    The best motor oil for my 2018 Tundra & 2021 Tacoma!
    By  ERIK,  a  Verified Buyer  from  Beaumont, Ca  on  July 22, 2022
    I wanted the absolute best motor oil for my 2018 Toyota Tundra & 2021 Toyota Tacoma so I looked no further than Amsoil! I like using Amsoil because I’m giving my car the best protection available. You can hear the engine purring and everything sounds so smooth running Amsoil. I run Amsoil on all my vehicles. It gives me peace of mind knowing I’m using the best oil out there! I highly recommend all Amsoil products for whatever you may drive!
    Bottom Line
    Yes, I would recommend this to a friend.

    Quality Products The Best
    By  MATTHEW,  a  Verified Buyer  from  Walland, TN 37886  on  July 21, 2022
    This oil is the best in my opinion. The last bottles I got had a older label on the back. I guess they ran out of newer labels. It didn't say it met my trucks latest requirements, but I'm sure it being Amsoil it did.
    Bottom Line
    Yes, I would recommend this to a friend.

    I use that sh*t in everything
    By  Ed,  a  Verified Buyer  from  Lecanto, Florida  on  July 20, 2022
    Some years ago when I worked at Ford in Engineering I had the opportunity to meet a Sales Engineer from Shell oil. I asked him about this new fangled synthetic motor oil. He told me "Ed, its the greatest thing since canned corn". He also told me that at the time Shell didn't even have a product on the market. He also said that because it doesn't break down all you needed to due at oil change time is only change the oil filter and add a quart. You don't need to drain the pan. (Not that I've ever done this). Living in the Florida heat with an 86 Corvette an 83 El Camino and 2012 Cadillac which are all high mileage I use the 5W-50 because I'm sure by now there is a lot of clearance in the rod and main bearings. Good stuff.
    Bottom Line
    Yes, I would recommend this to a friend.

    Heard this was the absolute best oil ever.
    By  SNJmom,  a  Verified Buyer  from  South Jersey  on  July 19, 2022
    Bought for my new used Honda CIvic with 60K miles. Oil life is at 70% now. Bought this in advance for my next oil change. Waiting for the Amsoil oil filters to come back in stock. In the meantime, the product was delivered immediately. Can't wait to try it. My son swears by Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Not sure about it
    By  21Tundra,  a  Verified Buyer  from  Idaho  on  July 17, 2022
    After people commenting how much quieter and better running their engines seem using this compared to other premium brands I thought I would give it a try. Put it in my 2021 Tundra and didn't notice engine or drivetrain or anything smoother or quieter than what was already in there(a major oil company synthetic). I am sure it is doing an excellent job lubricating but I notice no difference in how engine feels or behaves at startup, accelerating or anything. I generally change my oil at 5000 miles so SS certainly overkill but wanted to see if the hype was real. Also I don't understand why this doesn't carry an API License - I'm sure it meets the spec but why not Licensed? Won't buy this product again but may look at the API Licensed oil that you sell.
    Bottom Line
    No, I would not recommend this to a friend.

    Great Oil ! Good protection...
    By  JOHN,  a  Verified Buyer  from  Bradenton, Florida  on  July 17, 2022
    I had been using Pennzoil Ultra prior to using Amsoil so I'm starting from a great oil. I believe the Amsoil product is slightly better than Pennzoil Ultra and I have had great success with Amsoil in my 2017 Jeep Grand Cherokee. I also used it in my 2012 Chrysler SRT-8 (5-W40 grade) with great success also. I feel this is true synthetic oil offering better shear and wear protection than all others. It's worth the price difference to me.
    Bottom Line
    Yes, I would recommend this to a friend.

    So convenient and with big savings
    By  MIKEYR,  a  Verified Buyer  from  Scott County, Indiana  on  July 17, 2022
    Ive been using Amsoil in our vehicles for years. It is so convenient to only have to change oil and filter once a year. By skipping the extra oil and filter changes each year I am actually saving money. What is most important is saving wear and tear on the engines! Keep up the great work, AMSOIL!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Far superior product
    By  RAM4JC,  a  Verified Buyer  from  Central CA  on  July 16, 2022
    Been using Amsoil, exclusively, for decades, in many vehicles. Never one oil related issue. Currently have a 2020 Ram 2500 6.4 gas engine. Those engines are known for cam/lifter issues. Most "tick", some experience cam and/or lifter failure. My truck has 21k miles on it so far. I change oil & filter every 7k miles. Engine is not showing any sign of typical failure. No tick whatsoever. I have been an Amsoil dealer for 20+ years, and mostly only for my own needs. Amsoil is the best IMO. Also, check out PROJECT FARM on YouTube if you need further proof.
    Bottom Line
    Yes, I would recommend this to a friend.
