Customer Ratings & Reviews

I actually was told about Amsoil by a friend, one of those nut cases that does too much research into everything. I have an older truck, that I want to take care of so I try to feed it the best stuff I can. Amazon works great, their website is easy, their shipping is fast, their customer service is top-notch.

This oil stays cleaner longer and the oil itself doesn't break down. I run the Signature series 0 w 20 oil and the EA Filter. I drain and fill every 15K miles

This oil does what it says highly recommend this oil to anyone

Always quick, packaged professionally, and pricing is reasonable.

Everything was included and easy to install and use! Greatest Oil, easy filter install with all accessories included.

I use your signature oil in every vehicle we own and have done for 15 years. They are the best product out there.

is the best product

Amsoil is and Always been the most outstanding oil on the market. I’ve been using it for years and would recommend it to anyone that is thinking about buying it. Get it and treat your auto to the Great oil.

Great product, not happy with shipping cost. For what the cost is for the product and membership fee, shipping should be included

If the amount of videos they have showing the difference between them and the competitors isn't enough then the reliability and customer service will. It's a noticeable difference after switching to amsoil, the motor just sounds healthier and cold starts at 20 degrees both in my bb gas and diesel are almost instant oil pressure reading and you can tell the oil is going where it needs to. Even during the summer running high Temps and towing the the oil stays viscos and doesn't just thin out to crap. I'm sold till proven otherwise.

I drive a 2007 Toyota Tundra 4.7L V-8 2 wheel drive. These vehicles are known for dependability and running forever. With my truck at 260,000 miles (it runs like a new one) Amsoil is my first choice for engine.

An excellent oil at 0W for low temperature flow and start up when the weather is very cold.

Been using this stuff since 2018. I used Blackstone labs to confirm performance. I can say 25k, or 1 year is for real. I use it on all my vehicles.

This is a great product for the price.

Been using Amsoil since 1980. Its never let me down. I also use their gear and tranny products too. It beats every other oil in every test. Thats a fact. I also use their gun and rifle cleaner and lube. These items are great also. Can't say enough about Amsoil products.

Wish I could who my Rep is. The product is fantastic

Been using after buying Jeep last March after couple changes oil at time of change looks cleaner. Start with no problem when we had -30 temps. Will keep using.

This product seemed to make the engine run smoother, even my wife noticed it which is a good litmus test. Haven't had enough time running it to give a more detailed review, but it seems to be a quality product. The customer service was very good, I had an order get delayed due to poor weather. The distribution center called three times letting me know the status of the order and even called after it was delivered to make sure everything was correct. This level of caring about the customer is becoming a rare commodity in today's world, very impressive and thank you.

I have been using Amsoil since 1981 will not us any other oil in my vehicles!

Engine runs a lot smoother quieter fuel economy is better.
