Customer Ratings & Reviews

After the first freebie oil change, I switched to the Signature Series! I change the oil and filter when the algorithm hits 50%.

Have been using it im my 24 RDX past 20k Im still changing oil every 5k with amsoil filter. I cant feel much of difference, switching from mobil1, but the plan is to keep on doing it for rest of the life of the car. And i will see down the road, whem my car reaches 200k plus or more , if it is really protected my engine and turbo, as AMSOIL stated. Not to mention 5k changes, and not 10 or 20

We have been using Amsoil for many years now. I feel more confident than ever using it with the problems newer endings are having that Amsoil provides superior lubricants. We I have been very happy with the signature series line. We also use Amsoil in the transmission and transfer case and differential. We would rather spend extra on oil and repairs. Best of luck.

I use Amsoil OW20 synthetic motor oil in my wife's Ford Escape Active. Great oil. My wife puts alot of miles on her vehicle for work and I wouldn't trust any other oil besides Amsoil.

The 5W30 Amsoil Synthetic motor oil is best oil I've used in my sons Chevy Malibu. He travels to Wyotech in Wyoming from Illinois . I wouldn't trust any other brand of oil.

I’ve always believed that taking care of your vehicle starts with what you put in the engine, and AMSOIL Signature Series 0W-20 is my oil of choice. I use it in all my vehicles that call for this viscosity, and I wouldn’t have it any other way. I’m serious about vehicle maintenance, and I’d rather invest in quality oil now than deal with expensive engine repairs later. AMSOIL gives me confidence that my engines are getting excellent protection, especially with daily driving, highway miles, and the occasional spirited drive. It’s not the cheapest oil on the shelf, but quality comes at a price, and when it comes to protecting my engines, I’m not looking to cut corners. My philosophy is simple: Take care of your engine, and it’ll take care of you. AMSOIL has earned a permanent spot in my garage. Highly recommended to anyone who takes pride in maintaining their vehicles!

The best for my honda

This oil is a high quality oil and the packaging is convenient. The company is good about shipping quickly and packaging well. However, if you order an Amsoil filter (EA15K), check the product carefully against previous filters before instaling them. They have changed the design and it looks like quality suffered on the filters .

Great quality, fast delivery a true brand new trust

what can I say AMSOIL in everything... motor-tranny-diff, LIKE Butter

I believe every product is very high quality and well worth every penny.

Great oil

SUV defiantly feels more responsive and a lot quieter didn’t really think it would make a difference but it sure did.

Been using this oil for 60,000 miles no issues

Oil is amazing and burns slow in my engine!!!

Best oil in the world!

The best oil you can buy.

The signature series oil is phenomenal. All Amsoil products are great.

Just an excellent product. My 2014 tundra runs noticeably better with this product.
