Customer Ratings & Reviews

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.

After reviewing all the oils they had the Amsoil had the best flow rate for cold oil plus the signature oil is great

Everything is good with the exception of the availability AMSOIL oil filters.

love this oil

Es el mejor aceite desde que lo cambie mi vehículo da mejor rendimiento mayor toque y más suave

Great oil, engine actually sounds better and feels like it runs smoother.

Love the products but only thing I have an issue with is the lack of stock on and oil filters! When I order a oil change kit I don’t want the wix filter if I wanted that I’d go to the local parts store

I started using this oil in 2009 in a Toyota Avalon with 230k miles. That same car now has 456k miles and runs as smooth as a top! I run the oil for 20-25k miles, changing the filter in the middle of the interval. I would not put anything else in my vehicles!

I have been told this oil is the best of the best. They say I can go 20k on an oil change. Do I trust that? Not really. But I try to use the best products that I can afford. Do I see or feel a difference? No. I just have to take their word on it.

If you want the best. This is it. Engine runs better

Best oil I’ve ever used. My vehicles love it too.

I use this in my Granddaughters Kia. She loves the fact of only one oil change a year. She is really busy with work and school . She does not want to be bothered a few months with an oil change!

I have been using Amsoil 5-20 in my 2014 150 and my wife’s 2013 Eacape since we bought them, 2015 & 2016 respectfully. The Escape will lose about a qt a year and my truck loses none! I swear by Amsoil, like a famous saying, I use that S!|t in everything!
