    Signature 5W20 oil
    By  KEVIN,  a  Verified Buyer  from  Toronto  on  January 17, 2022
    I only use Amsoil's Signature series of oil for my 2005 Mustang GT. It stays cleaner than other oils and the mechanic comments on the cleanliness of it when I do my oil changes. The car runs smoother and I can extend my oil change intervals - the car is a daily driver with 273,000 kilometres ( or about 180,000 miles). I recommend Amsoil all the time - it is the best. Thanks Amsoil

    Signature Series
    By  Phil,  a  Verified Buyer  from  Nebraska  on  January 14, 2022
    I have used this 100% synthetic oil since the late 90s and attribute the long life and lack of major maintenance expenses of my vehicles to Amsoil and their product development dept. I used it in a couple of Nissan King cab pickups I drove daily for work as a salesman and my 2004 Dodge Dakota that I bought new had 239K miles on it when I sold it and never used oil, never changed water pump or timing chain. My 2007 Nissan Titan had 210K miles when we totalled it in a one vehicle accident with similar experience on original parts. I used it in my 2010 T&C van and am now using it in my 2019 Dodge Caravan and 2014 Nissan Titan.
    Bottom Line
    Yes, I would recommend this to a friend.

    True leader
    By  Poochgut ,  a  Verified Buyer  from  Wyoming   on  January 14, 2022
    Been really warming up to this brand. Seen endless testimony with 1 enduring theme. This is the best there is. Whether it’s pour point, thermal breakdown, viscosity index….doesn’t matter. Every other oil brand has to try to keep up with this one. Just talk to the engine builders, motor enthusiasts, and watch the videos from first hand perspective. The real kicker is, more often than not, Amsoil wins in pricing category too. Especially when you join in their membership plan. Wish I had figured this out years ago. Glad I know now though.
    Bottom Line
    Yes, I would recommend this to a friend.

    Signature Synthetic 5-20 oil
    By  GENE S.,  a  Verified Buyer  from  Lancaster, CA  on  January 12, 2022
    In years past, I've had engines go bad even though I did maintenance as required. since switching to AMSOIL, in this case 5-20 I've used just AMSOIL for my engines since 2003 and change oil once a year on each of the vehicles I've had. Every engine was getting the same gas or diesel mileage at the entire time I've had the vehicle and my maintenance repairs have been drastically reduced. I will not switch or change what I'm doing.
    Bottom Line
    Yes, I would recommend this to a friend.

    False
    By  WILLIAM,  a  Verified Buyer  on  January 11, 2022
    Love the oil but was a code for a free hat and instead of sending the hat with the oil it was sent separately and I was charged $28 shipping. Feel this is false advertising
    Bottom Line
    Yes, I would recommend this to a friend.
