    Terrific
    By  THOMAS,  a  Verified Buyer  from  Wisconsin Rapids  on  June 26, 2025
    I have been using this grade of oil for the last 17 years. It has been performing extremely well. I change the oil filter every 12,000 miles and the oil is changed every 24,000 miles. Between three vehicles, we have logged over 500,000 miles on this oil. It is a keeper.
    Bottom Line
    Yes, I would recommend this to a friend.

    great product
    By  RICH,  a  Verified Buyer  from  69130  on  June 26, 2025
    I have been using this product for over 10 years. I get 25,000 miles an oil change. Most of the time a year is up before I have made it to 25,000. Never had a single problem. Started using it in a 2003 Ford Excursion that was burning a quart every fill up, has not used any oil for 5 years now. Try it you won't go back to your former oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Oil There Is
    By  Broadcast Engineer,  a  Verified Buyer  from  Bristol, CT  on  June 24, 2025
    This is the oil my entire family uses. I have it in my 270k+ Corolla and my 1.8L engine is still rev happy and snappy. I drive 100+ miles a day, and I can tell you from experience, there is no other oil that could stand up to this kind of punishment.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  STEPHEN,  a  Verified Buyer  on  June 24, 2025
    I have to 2019 Silverado and the amsoil cleared up the hard shifts and the torque converter shudder. It is now better than new. After having the motor replaced I was very worried about my transmission, I gave it a try and its nothing less than awesome. Thx.

    Yes, I would recommend this to a friend.

    The best oil so far
    By  ALEJANDRO,  a  Verified Buyer  from  New Jersey   on  June 23, 2025
    I’ve been using this oil since my Mazda CX-5 was brand new in 2024, changing it every 5,000–5,500 miles. Occasionally, to keep the interval even — for example, if I’m at 16,500 miles and it’s time for an oil change — I fully replace the oil and filter with Castrol Edge Extended Performance until I reach 20,000 miles, and then I switch back to Amsoil SS. During those few miles with other oils like Castrol or Pennzoil, the car starts making all sorts of noises from the engine bay, behaves strangely, and drives noticeably rougher, almost like something isn’t quite right. Some might think I’m exaggerating, but I drive my car more than 10 hours a day nonstop, and I know every detail and sound it makes. Once I switch back to Amsoil, the car feels brand new again — all the weird behavior goes away. Since then, I’ve been using Amsoil in my motorcycle and in my generators as well. My family recently bought new cars (0 miles), and we’ve already purchased their SS oils to protect them from day one.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great product
    By  ADAM,  a  Verified Buyer  from  Arkansas  on  June 23, 2025
    You can see how well this oil cleans even when you pull the dipstick and how it cleans the oil right off of the dipstick. This is a great product.

    Just a good quality oil
    By  Cody,  a  Verified Buyer  on  June 22, 2025
    I purchased the 0W-20 Signature Series and an Amsoil filter for our Toyota Sequoia, with the 5.7 V8. As most of the Toyota owners know, Toyotas are typically loud. After changing the oil, there is a noticeable difference in the noise from the engine. I've used Royal Purple HMX in our 2007 Toyota Highlander which has held up great, making noticeable changes to engine noise and cleaning the engine. I'm hoping Amsoil will do the same, but time will tell.
    Bottom Line
    Yes, I would recommend this to a friend.

    Looks like good oil - if you can tell that
    By  JAMES,  a  Verified Buyer  from  Ohio  on  June 22, 2025
    Looks good so far. Amsoil had the oil in the 0-W16 I needed. Received it in very short time after the order. The long game of mileage will tell more how the oil does. How many miles on the motor since new before any major issues in the engine. Time will tell.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  JOHN,  a  Verified Buyer  from  IL  on  June 21, 2025
    AmSoil is a quality oil and the fact that they ship it to my front door with in 2 days of ordering online is a bonus. They also offer an oil analysis which I use to monitor my supercharged mustangs engine running E85.

    Top Quality and Excellent Service
    By  JERRY,  a  Verified Buyer  on  June 21, 2025
    I have been a mechanic for 40 years. I have done a lot of research on motor oil. I have always been skeptical of claims made by oil companies and additive manufacturers. I swear my vehicles run better while using Amsoil and I see an improvement in fuel economy. I couldn’t believe Amsoil would make a difference in how my vehicles ran and thought it was all in my mind. I did an oil change on my wife’s truck and didn’t realize that I didn’t have enough Amsoil to complete the oil change. I had another brand of oil and used it instead. I didn’t tell my wife what had happened but she told me her truck was not running the same. I did another oil change as soon as I replenished my stock of Amsoil and she immediately noticed the difference. Her truck is an F150 5 litre that now has 420000km on it and has never been apart. It has the original timing chains and cam phasers. I think that speaks volumes about my choice of oil. Amsoil’s service is second to none as well. My orders are almost always delivered next day. This review isn’t just for the 5w30 signature series oil. I run the 5w20 in the 5 litre F150 and 5w30 in my Ecoboost. I use the 0w16 in my daughter’s Toyota Camry also. I also run Amsoil in my 3 motorcycles and ATVs. I highly recommend Amsoil products.
    Bottom Line
    Yes, I would recommend this to a friend.

    True synthetic oil
    By  ALAN,  a  Verified Buyer  from  Jasper Mi   on  June 20, 2025
    Best oil I have used, highly recommend Amsoil. I been a customer, for 10 years plus. Prolongs engine life, I use Amsoil transmission fluid, grease, gas dyer. I even use it in my mower, and that has 2000 hours and runs so smooth.
    Bottom Line
    Yes, I would recommend this to a friend.
