    Great Product
    By  Horse-n-heeler,  a  Verified Buyer  from  Texas  on  May 26, 2017
    I have been using Amsoil for over 35 years. Our current commuter car (120 miles per day) has 265K miles and still runs like a top. Uses very little oil (less than a qt per change)
    Bottom Line
    Yes, I would recommend this to a friend.

    Having faith
    By  Stevie B,  a  Verified Buyer  from  Lockport ny  on  May 24, 2017
    I have this in my 2010 caravan. Have roughly 10k mi on the oil and it has discolored to a color I'd really want to change it at, but the dealer I got it from assured me that even though the oil will turn colors that it will NOT breakdown! So I'm trusting his word
    Merchant Response
    Hi Stevie: Like any motor oil, AMSOIL motor oil will darken as miles/time accumulate. In addition, AMSOIL motor oil is amber in color, and in many instances is slightly darker in color than other brands of motor oil. This, along with the oil containing outstanding detergents to keep the engine clean, the oil can darken within the mileage that is recommended for use. The dark color of the oil does not mean the oil is no longer good for continued use, and should not be the single determining factor on the oil's ability to perform as prescribed. Thanks for your comment!

    Best product in its field
    By  Chevy 2008,  a  Verified Buyer  from  Washington DC metro area  on  May 23, 2017
    I use this product on my chevy suburban 1500. Gotten better gas mileage, and of course longevity. Burn off is very very low. No other oil comes better!! This is the best. It makes Mobile One look likes water to synthetic oils. It takes a lot of miles to burn off this synthetic oil. Up to a year or 25,000 miles before changing the oil! Worth the money and investment!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Amsoil Signature Series is the absolute best
    By  Barney,  a  Verified Buyer  from  Oro-Medonte, Ontario, Canada  on  May 21, 2017
    While I was apprenticing to be a mechanic in the early 1980's a friend of mine challenged me to a comparison test between Amsoil 100% synthetic motor oils and conventional oil. As a result, I switched to Amsoil and have used it for over 30 years in all of my 4 stroke, 2 stroke, and diesel motors. It lasts longer, doesn't have the viscosity break down, and is a better lubricant than other oils.
    Bottom Line
    Yes, I would recommend this to a friend.
