Customer Ratings & Reviews

I’ve been running AMSOIL in my car and changing it every 5k miles. The engine runs smoother and quieter, and the car just feels better overall. Even at 5k, the oil still looks good and does its job. Definitely worth it if you want your engine running great and well protected.

I looked at reviews for manu oils and filters. I decided that Amsoil was the best option. My car was new when I put amsoil in it.

I have been using Signature oil for at least 10 years now and have never had an issue. And the added mileage between changes makes it more affordable than conventional. I have even emailed a couple questions, once about their marine 2 cycle oil and they respond quickly and positively.

Very good oil it smoothed out my engine and made it quiter ,I can feel how much better the engine runs. 2017 2ss camaro v 8 engine.

Oil kit is real sweet with the gloves and funnel made it real easy to change the oil.

Yes, IMHO, Amsoil 5w-30 Full Synthetic is the best oil out there. Won’t run anything else. Might be a little on the expensive side, but so is a rebuilt engine😂. Seriously though, it’s great oil!

This oil is literally the best oil ever. My Toyota now has 430,815 miles on it and still going strong. I love amsoil will never in my life use any other brand I even run it in my lawn mower and dirt bikes. Keep up the great work and excellent top tier oil products. Thank you guys. I’ve been using amsoil for over 20 years now.

Best synthetic oil. Keeps motor running strong.

Highly recommend. Great product at a great price.

Love Amsoil and their products!

Just got a brand new engine replacement on a 3.3 v6 Hyundai Santa fee and ask them if I could bring or told them that I wanted Amsoil signature serie synthetic and they said they would put synthetic but only what is recommended wich was either Shell or quacker state so as soon I got out the dealer after 21 miles drop it and put this in I like to protect my investment thanks Amsoil

Have many years using this Oils and I wouldn’t trade it for another brand.

Didn’t believe in it until I tried it for myself and noticed the difference performance in my car 🙌🙌🙌💯💯💯💯

The best oil on the market I feel; tested and compared to other top names it always comes out on top !

We utilize this for a lot of Mazdas, each of them is doing outstanding with the oil. Good bump in mpg, and heat down. Much more pleased with smoothness under throttle, delivery of power is exciting. Going on 105k, 177k and more we love the performance and protection. All of them raced!

I have been using Amsoil Signature for almost 20 years on multiple vehicles. The results have been outstanding. The engines on my cars run flawlessly, especially in our very cold Alberta winters. I will never use any other oil.

Love the Products, Its like Franks Hot Suace. I put that **it in everything. Show cars, Race Car, Jeeps, If it takes Oil, its Amsoil. Bonus I have the best dealer, in the United States, who also supports Veterans. Hinson Synthetics.
