    Better running engine and less oil burning than Mobil 1.
    By  JERAMEY,  a  Verified Buyer  from  Illinois  on  July 02, 2024
    Very pleased with Amsoil. It's expensive but it has less evaporative loss and it's still new looking at 1500 miles. I still wouldn't recommend going over 5 to 7000 miles on any oil
    Bottom Line
    Yes, I would recommend this to a friend.

    Excellent Pick
    By  CHARLIE,  a  Verified Buyer  from  Macon, Georgia  on  July 01, 2024
    I bought a new Hyundai that requires 0w-30 synthetic oil. Hyundai recommended Quaker State oil but I couldn't find it any where. AMSOIL came through and it works wonderfully. I am now sold on AMSOIL! Thanks guys!

    Best Oil no debate!
    By  RICARDO,  a  Verified Buyer  from  Philadelphia   on  June 30, 2024
    I switched all of my factory Ac Delco fluids to Amosil and my 16” Silverado has been a machine since! Best Fuel mileage was 26.8 when the truck had 11k miles, 7 years ago now 102k on it I just got 24 mpg and it has everything to do with the signature series. Don’t cheap yourselves out and protect your investments. My dad drag raced for many years and always swore by Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Lubricant on the Market
    By  RAY,  a  Verified Buyer  from  Virginia   on  June 30, 2024
    I believe II can tell the difference using this oil vice other synthetics. Engine runs very efficiently and does not consume any oil using this product despite operating under heavy loads.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  RANDY,  a  Verified Buyer  from  Catonsville, MD  on  June 29, 2024
    I am an old timer who has been a serious gearhead since the 1950's. I have been using Amsoil products for a very long time and have always found them to an asset in my garage. I have always tried to use the very best lube oil in my vehicles.

    Amsoil For Life! Period!
    By  JOSEPH,  a  Verified Buyer  from  New York  on  June 27, 2024
    I recently had the little 5.3 L83 in my 15 Silverado freshened up with goodies from BTR, Frankenstein, GM Performance and the list goes on. Engine Dyno’d at 450 whp. At 8,000 RPM. I was using mobile 1 oil but at high rpm it didn’t feel smooth so I rarely got on it. Until I changed to the Amsoil Signiture Series OW-20. Now I do multiple pulls to 8,000 a day and the engine runs smooth as glass, also haven’t been burning as much E85 either. I’ll never use an other oil again and can’t wait to change my transmission fluid to Amsoil as well. Performance oil! Insane!
    Bottom Line
    Yes, I would recommend this to a friend.

    By  JEREMY,  a  Verified Buyer  from  Florida   on  June 27, 2024
    Got a used car with 100k miles and after reviewing and comparing having used amsoil with my old car this is been the oil that keeps the engines running like clockwork. Old car with 300k and starts like new thanks to amsoil.

    Don't forget to buy in bulk
    By  JT,  a  Verified Buyer  from  anytime, anywhere, anything  on  June 26, 2024
    The oil tests extremely well in lab tests, I highly recommend using this oil above others. I've used it in fleet applications and personal vehicles and I can vouch it'll hold up any type of usage rather you're a ride hailing driver, someone who does ride share or you're just a casual over the road driver... Absolutely, Amsoil has you covered. Check out their other products and see the results for yourself. You cannot go wrong. I've used their OE/XL & SS lineup. 0w20, 5w30 & 10w30.
    Bottom Line
    Yes, I would recommend this to a friend.

    Reduced wear
    By  DAN,  a  Verified Buyer  from  Williamsburg Va.  on  June 20, 2024
    Just received the oil report for my 05 Corvette, which has 125,000+ miles. I have owned this car for 18 years and have the oil tested at least once a year. I just switched to Amsoil from Mobil 1 the last oil change and the comments from the lab read as follows: Spotless results from this oil sample. Wear metals are some of the best we have seen in recent history after the longest oil change interval on the page. Five other oil change test results were shown, dating back to 2018. Metals like Aluminum, Chromium, Iron, Copper, Lead, and tin were down significantly. I am happy I switched all of my cars to Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    A Great Oil.
    By  DAVID,  a  Verified Buyer  from  Indiana  on  June 18, 2024
    I'm running this oil in my 1999 Chevy Silverado 1500, with 220,000 miles on it. The motor runs quieter, and my oil pressure actually increased by about 10 lbs at idle. Why I don't know but I'll take it. I've always been happy with AMSOIL. I run it in everything I own.
    Bottom Line
    Yes, I would recommend this to a friend.
