    Ultimate protection and gas savings
    By  SCOTT,  a  Verified Buyer  on  September 13, 2021
    I noticed my engine runs smoother and when it's -20 below zero my engine starts right up with no tapping! I recommend amsoil to everyone I know. I will never use any other oil but amsoil. Fast shipping and great customer service.
    Bottom Line
    Yes, I would recommend this to a friend.

    The Best!
    By  WILLIAM H,  a  Verified Buyer  from  Houston, TX  on  September 13, 2021
    I have been an Amsoil user for over 25 years, and it has never disappointed! I use it in all my vehicles, my lawnmower, and anything else that uses oil. I'm a busy driver, and I can be rough on my vehicle, but I drive with confidence knowing I have Amsoil in the engine! I have recommended all of their products to many friends over the years, and they all agree....It's simply the best!
    Bottom Line
    Yes, I would recommend this to a friend.

    Outstanding protection
    By  SCOTT,  a  Verified Buyer  on  September 13, 2021
    I run the signature series oil in everything I own. I had this oil in a truck when a head gasket was blown while driving home 40 miles away. My engine was running hot but did not loose the engine and I made it home. I trust nothing else!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Amazing!
    By  Vince G.,  a  Verified Buyer  from  Long Island City, NY  on  September 13, 2021
    Signature Series holds up very well to the drain intervals recommended by the manufacturer (10,000 miles/1 year) even without an AMSOIL filter and with +5% fuel dilution in oil analysis reports. Honestly, I even think it has an effect on the oil life monitor, since it did not trigger a maintenance warning until about 700 miles left in the drain interval while a competitor brand triggered it at 1,000 miles left. I own a 2017 Volvo V60 Cross Country and use 0W-30 Signature Series instead of 5W-30 Castrol Edge Professional as recommended in the owner's manual (since the car requires ACEA A5/B5).
    Bottom Line
    Yes, I would recommend this to a friend.

    Signature Series synthetic motor oil
    By  PHILIP,  a  Verified Buyer  on  September 13, 2021
    I've been using Amsoil for at least 15 years. I started when my brother-in-law, an auto who owned and operated a shop of his own, turned me on to it. While I'm not personally sure about the benefits of the PI gas additive (I have no idea how to evaluate the benefits), I am 100% sold on the Signature Series synthetic motor oil and Ea filters. I have driven almost all my vehicles well over 200,000 miles, and had only one not go until I decided to sell it. The one that blew a head gasket on me was done in my one of my daughters, who at the time was a teenager learning to drive.
    Bottom Line
    Yes, I would recommend this to a friend.

    The absolute best oil for all of my vehicles
    By  ERIK,  a  Verified Buyer  from  Beaumont, CA  on  September 13, 2021
    I finally stepped up to the best motor oil and I’m glad I did. Amsoil came highly recommended to me by a good friend who swears by it so I made the switch. This oil is the best out there. I can actually hear the engine running smoother after switching to Amsoil. If you want the best oil I’d definitely go with Amsoil!
    Bottom Line
    Yes, I would recommend this to a friend.

    5w-20 Signature Series Synthetic oil
    By  KERRY,  a  Verified Buyer  from  Calvary, Ga.  on  September 07, 2021
    I have used Amsoil 5W-20 Signature Series synthetic oil for three years now. This oil was recommended by the manufacturer of Ram trucks as the synthetic oil to use in 2019 Ram trucks. This is by far the best synthetic oil that I have ever used. The oil is still very clean at oil and filter changes. I will continue to use Amsoil products!
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Full Synthetic on the Market
    By  SCOTT,  a  Verified Buyer  from  Port Hueneme, CA  on  September 07, 2021
    I use the Amsoil Signature Series in all of my vehicles, (including a 2016 Ram 1500 Hemi, 2019 Honda Civic Turbo, and 2021 Mazda 3), except my 2021BMW 330i that requires Amsoil European synthetic. I feel better knowing the best is in those engines. Nothing is better than Amsoil. Checkout the Project Farm videos on Youtube to see for yourself. Amsoil may cost a bit more than some competitors...but my $165,000 group of vehicles is worth it.
    Bottom Line
    Yes, I would recommend this to a friend.
