Customer Ratings & Reviews

Love the oil not so much the filter.I really wish you guys would get the amsoil ea17 filter back in stock, its been far to long they've been on back order.

I have used this product in my 2000 Camry since 2004 (odometer: 71,000) until the present time (odometer 328,000 +) and in my 2006 Camry since May, 2025. I don't think that there is a better oil made! (By the way, I usually change the oil filter--I use the WIX oil filters--every 6 months.)

I have done oil samples and after next test it should be a very informative result

From my 67 chevelle to my 2024 GMC Sierra my wife's car and the kids this oil has me covered

I have used it in my f150 with 2.7 got 285000 on my truck with no engine problems what so ever.

I always put Amsoil in all my vehicles and I highly recommend oil the 0/20 signature series is the best on the market never had a problem with any of my vehicles using Amsoil

Iam gone stay a amsiol fan forever

Great oil is the one thing I can rely on when the auto manufacturers keep reducing their oil viscosity to achieve fuel efficiency for some tree hugging politician.

Read all the reviews , watched all the videos, it's the only oil I'll trust in my car

Whether viewed in terms of quiet operation or evaporation loss, it stands alone—no other product can hold a candle to it.

Did a recent oil change in my 2020 Cadillac XT6 and used this oil. The vehicle has alittle over 90k. The oil appears to have quieted down lifter noise and engine runs very smooth.

Its the best syhthetic oil out there

My son's 1991 Miata 1.6L with 190k miles has had a worsening lifter tick since we bought it almost a year ago. I use Amsoil in ALL of my vehicles so in this Miata we use the Mazda rec'd 10w30 Amsoil High Mileage. I trust this oil to protect the engine, even when it's making noise, and even while my son drives "spiritedly" pretty much at all times! We're not ready to build a fresh engine for this car just yet so I decided to try out Signature Series 5w-50 and see if the added viscosity would help quite the lifter tick. I am happy to say that since the first startup after the 5W-50 oil change, we have not heard the lifter tick even once in the last 1000 miles of driving. Yes, it's just a bandaid, but it'll do just fine until we get around to the engine rebuild and a new set of lifters.

Excellent product. Have used it for years! I will admit its pricey.

I bought a brand new 2025 Toyota RAV4 hybrid and I wanted this car to have Amsoil in it from the very beginning so I dropped the factory oil at about 500 miles and put in Amsoil I want to have one of those stories of a million mile vehicle running on nothing but Amsoil. It's just a shame they are out of their oil filters for the time being.

Due to an online order error two orders were made at the same time. As soon as I received confirmation in an email I immediately responded to explain that this was a duplicate order and to please cancel. No one got back to me. In a few days later both the orders arrived. I reached out explaining that I had sent them and immediate email asking for it to be canceled and no one responded. And the only way they'll accept the order to be returned is if I pay for shipping. This is very poor customer service because had you responded within the moments of me sending the email you could have canceled that order instead of ignoring my email and sending the second one. And then putting it all on me. If you're going to send out a confirmation of order received you should be able to respond to return email and cancel it if it was made in error.

No oil beats this. The oil station I change it on my vehicles loves Mobil one. I try to get them in this brand Amsoil. I always bring my own oil. Thanks for a great product!

Excellent product- when I need my engine to go the distance this is the real deal! Never had an engine go bad using Amsoil!! That’s hundreds of thousands of miles in all conditions!!

I really like being able to get the prices from directly ordering Amsoil and the quick shipping service. Makes my life and my trucks life easier!

Great choice, my engine runs smoother than before. I'll switch all other fluids to Amsoil soon. F150 4x4 out.
