Customer Ratings & Reviews

Love this oil and how my truck runs on it!

The price of cars make me want to have them last and operate trouble free. Start with excellent oil and filters for your best results. Amsoil is as good as it gets for daily drivers.

First time changing oil with this product and it was below zero in early January. Mileage increased, even using winter fuel.

Finally someone makes top of the line synthetic 0w-16!!

A great product! have a PU with 250,000 miles and still runs like a clock.

Great oil but a bit pricey

I have a brand new 2025 GMC Sierra AT4 1500. My very 1st oil change at 1k miles break in was this product. Amsoil was highly recommended by other GMC owners. My AT4 will only have 0w-20 from Amsoil in it. Highly satisfied.

I've been using Amsoil in my Harley for years. Way better performer than HD's Syn-3. Runs cooler too. Also using in my GT350 now. Only been a couple 100 miles so far, but my expectations are high. The price was more that competitive and delivery was fairly quick. Will continue to use Amsoil oils in all my cars and equipment.

This is the only oil I will use in my super duty. I’ve been using these products for years. Absolutely love Amsiol.

Great oil. Makes the car run like butter.

Best oil around - all I'll ever use in any of my vehicles

5/20 synthetic after 20k in my 2004 element 198k miles was still semi clear honey like. Very impressive

Excellent oil I've used for years.

Only oil I will use in my 21 sport hatch civic. I feel like you get what you pay for with this product. I need to send a sample in and see where I’m at with the longevity and my driving style/habits.

All i run in my hemi 5.7 several engines never a problem and I'm rough on trucks

Before the current vehicle I had an Alfa. It received one free oil change. I did it to make sure there were no warranty complications. I always do the first change on a new vehicle way early. So on the Alfa I used Amsoil. On the factory change they put in their Mopar stuff. The car used a quart in approx 3-4K miles. I switched back to Amsoil, the car would use less than 0.5 qt oil in 6K miles. I think the Chevy Tahoe will be the same. There was no free oil change with the Tahoe so I did the first change at 2K using Amsoil Signature 0-20. I could feel the Tahoe ran better after the change. A very long story just to say, it's just better oil.

Amazing product, fast reliable shipping with no hassles! Definitely would recommend AMSOIL to EVERYONE!

Always pleased with using amsoil. Keeps my engine running smooth and clean. Oil is never black when due.

Have been using amsoil since the 80's quiets down gm lifters and is the best engine oil

I have 2013 Ford Flex SEL and a 2011Ford Flex Limited EconoboostTurbo. This oil is superior to any oil I've ever used. The capillary effect allows it to flow into places other oils do not go unless forced. I had a slight grinding noise on start up on the turbo flex. After switching to Amsoil I stopped hearing it. My other Flex with 250k miles is quiet as a mouse after switching to amsoil. Friend was losing a quart every 300 miles switched over to amsoil no more top offs just regular oil changes again. Just ordered 2 cases of trans fluid to do both flex. If you care about your vehicles use amsoil. There is a noticeable difference. I can go another 100k using this oil.. Thanks amsoil.
