Customer Ratings & Reviews

Have been using Amsoil in several vehicles and the engines run so smooth and clean. Looking into the valve cover you can see how clean the engine really is. Highly recomend this oil.

I have found a slight improvement in gas mileage and a cleansing effect in my vehicles since using this product. Also, in one of my vehicles, the internal engine sounds are quieter which I like. There is. O doubt that using this oil is a long term win to extend the life of my vehicles engines.

I want the BEST for my cars,as an automotive technician for over 30 years I've used other brands. But form my experience for get the rest pick the best .AMSOIL just can't go wrong.

I have many vehicles. They run quiet and run very well. Amsoil is the way to go. Far superior to the competition. Many years experience. Engineering quality! Dave H

I have used signature series oil for years now. It is the only oil I will use in my vehicles. As a retired mechanic I have tested and used many different brand name oils and Amsoil is without a doubt the best available on the market. So glad to see 0W-16 signature series oil is now available for all the Toyota and Honda lovers out there.

They say that Amsoil is as good as it gets. I keep buying it. Amsoil products have never disappointed me. I like my vehicles to be paid for. I like to be able to keep them active and dependable. I enjoy the relationship I feel to a vehicle that people associate with me. It seems like Amsoil has helped me keep all of my vehicles more years than average. That's what I want.

Awesome

I'm so glad I switched to amsoil I will never use any other oil

I wanted to get the best available 0W20 full synthetic oil for my 2018 Honda Civic LX 1.5l Turbo. Using with WIX XP filter. I think the engine is happy.

Just like the quarts , but a little cheaper!

Switched to Amsoil after using other brands and not being able to get them at the time I needed to do an oil change. I now use one brand for truck and also use for my motorcycle s as well, a it is delivered to my front porch! So far I love the product!

Engine was smoother

I just changed the oil in my 2021 Jeep Wrangler 3.6 for the second time using AMSOIL. I decided from the start after purchasing I wanted to use the best. I did a lot of research on the top oils used, and from what I could find, AMSOIL was right there at the top. I have 4 vehicles and am now using AMSOIL in all of them.

I'm a Licensed Chief Engineer for a US Government Contractor. I've spent the last 29 years designing, and maintaining machinery. Amsoil is not the cheapest, but it is the best from an Engineering perspective. Not only do I use it at work, but I use it in all my vehicles and even my daughter's Gokart.

Been using Amsoil for many years in everything I own. It has helped make my investments last longer!

You can’t go wrong with Amsoil.

I've been using Amsoil Signature on my 2020 Silverado RST Z71 since it was new. Absolutely the best oil on the market, hands-down! While it is a little more expensive than regular store bought oil, the peace of mind and the ability to go 10,000+ miles on an oil change is an exceptional trade off. Id definitely recommend all new American trucks owners to use Amsoil Signature, it just doesn't get any better to protect your investment

I've used this product on my 2021 Ram 1500 since my 1st oil change and it has performed great. The extended oil change miles are a big help when driving a lot of miles. It's a bit expensive on the front end but the long term pay off is well worth it. I just hit 99,000 miles on this Ram and this product is superior to any of it's competition.

Put new Amsoil in my 2000 Tundra. Engine runs so much smoother. Great oil.. Fast service and shipping. Had product in about 5 days after ordering online.
