I’ve been using AMSOIL for over 15 years and will until …. For my vehicles there is no other oil which compares. Awesome protection and piece of mind!!!

Avec cette huile, fini la consommation d'huile! Fini les lifter qui claque ou flacotte, mon moteur tourne très doux malgré ses 195000km!

I am very happy with all the grades of oil for the different vehicles in the family. They keep the old engines running smoothly for the whole year long.

Just as good as the year long lasting 5w30

This oil is what it says. Lasts all year long, as long as you don't have a leak.

Very good engine oil nothing better than Amsoil Signature Series.

Amsoil is the best product, great service, fast shipping. I have used Amsoil for several years and am very satisfied.

what I like is that they do what they SAY on time with good stuff.

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
