    Remarkably quiet
    By  BRADLEY,  a  Verified Buyer  from  Bakersfield  on  October 17, 2025
    Manufacturer calls for 0W-20. 5W-30 just feels better for my hot climate. My 6.2 purrs as quiet as a mouse (If you ignore the growl of the Flowmasters)
    Bottom Line
    Yes, I would recommend this to a friend.

    Wide mouth bottle
    By  JEFFREY,  a  Verified Buyer  from  Rochester, NY  on  October 16, 2025
    Well, oil is oil, so there is not much to say about the oil. Now the bottle is worth talking about. The wide mouth on it meant I didn't spill any oil while pouring it into the engine. My order arrived very quickly, which is a plus these days. I have been having issues with parts arriving promptly.
    Bottom Line
    Yes, I would recommend this to a friend.

    Impressive oil
    By  TROY,  a  Verified Buyer  from  Iowa  on  October 14, 2025
    I was never a believer in AMSOIL because of its price. Other oils met all of f the required specifications and were much cheaper. Reluctantly I decided to give AMSOIL a try. I’m liked the fact that it had the weight( 0w30) which I wanted. I love ve in a state with brutal winters, and I figured since AMSOIL had a lower pour point then many other oils, and had touted lubricity and superior protection, that I would at least give it a try. I noticed immediately after start up that a clatter that has always occurred for a second at start up in the top end of the engine( even when brand new) was gone. No other oil has ever caused this quiteness to be achieved. I’ve only ran the AMSOIL about 200 miles now, but that start up flatter is gone and the entire engine runs much smoother then ever before. I will continue to use AMSOIL from now on. My car only has 60,000 miles on it, but I wish that I would have used AMSOIL from the start. I do believe so far that it really does provide superior lubrication. Winter hasn’t arrived yet, with it brutal-30 temperatures, but I feel much better knowing that my car has a whole new level of protection then ever before.
    Bottom Line
    Yes, I would recommend this to a friend.

    Signature Series 0w20
    By  Julio,  a  Verified Buyer  from  Alberta  on  October 14, 2025
    As a retired mechanic myself, I've used Amsoil products in all my vehicles for decades now, including this 0w20 Signature Series product in my pickup and my wife's vehicle. Love the instant oil pressure visible on the gauges during extreme cold winter weather, as we're not always able to plug the vehicles in. Had over 300k on my wife's vehicle when we sold it to get a larger vehicle, and it still ran as good as the day we bought it, over a decade ago.
    Bottom Line
    Yes, I would recommend this to a friend.

    Still the Best!
    By  GAYLORD,  a  Verified Buyer  from  Fairfax VA  on  October 12, 2025
    My 08 4 Runner just reached 200k. I have been using Amsoil since 2010 and my vehicle is running like new! I just finished changing all my fluids with AmsOil and considering its service interval, it has saved me a lot of money.
