      By  ALEKSANDR,  a  Verified Buyer  on  October 11, 2026
      Have been using it im my 24 RDX past 20k Im still changing oil every 5k with amsoil filter.

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
      Bottom Line
      Yes, I would recommend this to a friend.

      0w40 signature series
      By  KEVIN,  a  Verified Buyer  from  Missouri   on  October 11, 2026
      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.
      Bottom Line
      Yes, I would recommend this to a friend.

      ⭐⭐⭐⭐⭐ 5/5 – AMSOIL Signature Series 0W-20: My Go-To Motor Oi
      By  Andii,  a  Verified Buyer  from  North Carolina   on  October 10, 2026
      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!
      Bottom Line
      Yes, I would recommend this to a friend.

      Good Oil
      By  DANIEL,  a  Verified Buyer  from  GA  on  October 10, 2026
      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 .
      Bottom Line
      Yes, I would recommend this to a friend.
