Customer Ratings & Reviews

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.

I’ve used Amsoil from day one in both vehicles. I have 2007 GMC diesel and a 1992 Chevrolet 1500 . Both vehicles have almost 400,000 kms with absolutely no issues. Absolutely great products!!!!

True synthetic motor oil. Ester based, outstanding protection for my application.

It’s been a great oil. Why not run the best!!!

GOOD

Amsoil products have exceeded my expectations, this is truly high quality engine oil i can trust for myself, and my customers, i am a very picky technician and i expect nothing but the best for my shop & clients! Amsoil products is #1 in my books!

I have used this in every Toyota I've ever owned and have almost 300,000 miles on one of them, and you'd barely know thanks to Amsoil. Really superior engine lubrication and protection for long term engine life.

I Have been using this in all of my vehicles for 2 decades now and still nothing else beats it. Period. Even with 25,000 miles annual commute, Amsoil shrugs it off. I really miss Amsoil filters though. They were fantastic too!

This oil is amazing I have noticed lower operating temperature and slightly better fuel economy, I have used other Amsoil products and am very impressed with them all
