Customer Ratings & Reviews

I use amsoil signature series in my bmw suv it provides excellent performance on a 10000 mile service interval, this is the best money can buy no doubt about it, I would recommend it to anyone

Can not go back to any other make of Oil. This is the best.

I have been using Amsoil for past 10 years in all my and my friend's vehicles. And can vouch by it.

This is keeping my old 2012 hemi ram running like new. 300,000 and counting -

I am very happy with amsoil. I think it's the best oil I've ever used. And really excited that my local auto parts store carries it now.

I choose Amsoil after reading reviews from other people. My first purchase was for my HD motorcycle. Reason for Amsoil over HD oil, HD has one oil for engine/transmission and primary drive, I do not agree that one oil can cover three components. Amsoil offers separate oil for each component which mirrors my belief of separate oils. I am totally pleased with my decision to use Amsoil, engine, transmission and primary are all operating much better. I made a second purchase for my Subaru Forester; oil not changed to date but will be in the near future. I found it very easy to place my order and delivery time is amazing.

This oil protects and extends engine life like no other I have used. My 2023 Genesis is exactly three years old with 190,000 miles on it. Runs like new. My prior rides including a 2011 Hyundai Elantra (I purchased new) spanned over 425,000 miles without a single engine repair. The best protection for long life... Amsoil Signature grade oils

Using this gives me confidence that my engine is protected over traditional motor oils.

Solid oil, the new bottle looks spiffy, performs extremely well, and lasts a long time in my Accord 2T with a proper filter.

Best oil for my acura

We've been using AMSOil for about 20 years. Love that we can go extra miles between oil changes knowing that the engine is protected. See better gas mileage as well!

I've been using it for years. The only synthetic oil I will use.

I switched to Amsoil years ago and it's the only oil I use now. The best part now of where Amsoil has a distribution center, I usually get my orders next day. Very high quality product and improved the drive on two of my vehicles.

I have been using Amsoil in all of my vehicles since I bought them. 2005 Mustang is still going strong with 250k miles

Have used Amsoil for years in my motorcycles, will trust nothing else for my Alfa but Amsoil. Always dependable, no slugging and after thousands of miles drains virtually clear. Won't trust any of my vehicles to anything else. The Bees 🐝 Knees!

Even after 4000 miles of heavy driving through the mountains, we drain this oil and it was still a golden yellow color.

I have been using this brand of oil for many years. It is far superior than any other brand. It may cost a little more but, “pay it now or pay it later “!

The last 2 weeks has been...well, HOT. It is normal here in Texas, for daily temps to exceed 3 figures, and 104°+ on an August afternoon is expected. What is not expected is your engine oil to break down at continuous extream temperature and conditions. I don't worry about that because I only run Amsoil in my truck. As you can tell by the testing and extensive information posted by Amsoil for everyone to see how the other oils fail to protect your hard working engine. Quality lubricants you can rely on, protection you need. My truck does me no good when it is broken down, So i only run the best... Amsoil.

Reasonable price for a gallon of 5w-30 for my 2008 Prius.

I love the signature series, oil and filter that goes with it. However, the filter has been out of stock for several months with no update on when it will return. So I suggest not buying this product until the filter is available.
