    Running in all my vehicles
    By  Jerrod the Main,  a  Verified Buyer  from  TX  on  February 25, 2018
    So far so good. No problems. AMSOIL has came highly recommended from my research. I plan on keeping my vehicles for the long haul and it made sense to step up to a better oil for my 2015 silverado 1500 z71 and lexus rx350, both of which use the same oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Premium oil on market
    By  Dan,  a  Verified Buyer  from  Minnesota  on  February 25, 2018
    I started using Amsoil several years ago in my 2-stroke YZ125 and was very impressed. Back then I was rather unfamiliar with Amsoil so I started doing some research on Amsoil and other competitor brands, because I only wanted to run the best lubricants in my equipment. What my research uncovered for me is what I now believe to be so great about Amsoil. Amsoil provides plenty of literature from third-party testing that truly separates their products from the rest of the field. Other brands will only tell you what they want you to hear, but what is great about these testings is that we as customers can see for ourselves side-by-side test results, and the results speak for themselves. In these tests Amsoil's products are put through the ultimate rigors and unbelievably harsh conditions and STILL protect against breakdown and wear. The one thing about Amsoil is you won't see expensive ads on TV about what the company's oil "can or will do" for your engine like the "Big brands",however, with Amsoil you can read for yourself from unbiased third-party test results that PROVE Amsoil's greatness over competitor brands. As you can tell I am absolutely sold on Amsoil now days and run it in all of my vehicles even my lawnmower and snowblower. With harsh MN winters I need the best oil to protect with cold start ups. I would encourage everyone individual who is new to Amsoil, or even a long time user, to take a look at some of the testing that has been done on their products. Read the results! If you're still not sold on Amsoil I'm not sure what else to tell you.
    Bottom Line
    Yes, I would recommend this to a friend.

    Nothing but Amsoil
    By  None,  a  Verified Buyer  from  Navasota, TX  on  February 22, 2018
    I've been using Amsoil in my vehicles for over 10 years now and in my opinion it is the best and less expensive in the long run. Less oil changes, less maintenance and better gas mileage. Over 280,000 miles on my 2004 truck and does not use a drop of oil between changes. Would like to see more in and out oil change businesses carry Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    100% sold on the value of this product
    By  Perk,  a  Verified Buyer  from  Pittsburg, Texas  on  February 21, 2018
    When you buy something you expect it to do the job it was made for. AMSOIL does that for me. I became an Amsoil fan around 2001 when my Chevy pickup was first sold to a farmer here in Pittsburg. I was living in Alabama at the time and I had put AMSOIL in both my vehicles and was very pleased with the performance improvements i.e. mileage, performance, etc. We moved to Texas and my wife said I needed a pickup. Every Texan man needs a pickup, so we bought a 2001Chevy Silverado with 99,000 miles on it. It ran like a new truck. I immediately put AMSOIL in it and now with 132,000 miles on it it still runs like a new truck. I haven't had to do any maintenance on it other than maintaining fluids, tires, wiper blades and the like. And i expect it to continue performing like that as long as I have the vehicle. I will never use any product other than AMSOIL lubricants in my vehicles. I also use them in my Toro Zero turn riding mower.
    Bottom Line
    Yes, I would recommend this to a friend.

    Very tough oil
    By  Full out,  a  Verified Buyer  from  Port Saint Lucie Florida  on  February 20, 2018
    I have been running amsoil For over a year now. Naturally aspirated v6 in a 2011 Ford Explorer and TwinTurbo V6 ford F150. We know how turbo charged engines can generate heat and breakdown oils much quicker I really like the extended drain intervals and even with almost 13,000 miles on my F150 the oil that came out was still very thick. probably could've gone several thousand miles more. Usually with that kind of mileage and that kind of abuse oil comes out the consistency of water. I'm not easy on my vehicles either And tow from time to time. I just purchased oil, transmission oil, and filter for my Honda TRX 450 Atv. You have a customer for life!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Ever since being introduced to Amsoil, it's all I use. I've put it toe-to-toe with friends using other brands of oil, and they've eventually seen the light and moved over to using Amsoil as well. Never disappoints.

    Performs as Advertized
    By  icesysman,  a  Verified Buyer  from  Albert Lea, MN.  on  February 15, 2018
    I'm currently using your 5W-20 synthetic motor oil in a 2008 Toyota FJ Cruiser. Startability in sub-zero weather has been excellent.I've also noticed an increase in gas mileage, which is a definite plus. The engine runs quieter and smoother than it did with conventional motor oils. I will continue using Amsoil products until I'm no longer able!
    Bottom Line
    Yes, I would recommend this to a friend.

    2017 Ford Explorer Base
    By  Dienliv,  a  Verified Buyer  from  Walnut Creek, CA  on  February 14, 2018
    Bought a brand new 2017 Ford Explorer (NA 3.5L). After a couple thousand miles, I changed the oil over to Amsoil Signature Series, using Amsoil's filter as well. I've been changing the oil based on the in-dash oil life counter which gets to right about 10,000 miles for servicing. All has been working just fine so far at 25k.
    Bottom Line
    Yes, I would recommend this to a friend.
