I being using this oil since 1993 and won`t change it for nothing else!!!!!

I’ve been using Amsoil since 1996. It’s the best oil I have ever used. I actually get a couple more miles per gallon fuel economy plus I don’t have to change oil nearly as quick.By getting longer life out of Amsoil it’s no more expensive than using oil you have to change every 3-5,000 miles. I go 24,000 miles and use 2 filters in a complete cycle. The oil keeps my motor clean and efficient. This oil is the Best of the Best

I love Amsoil, been using their oils since 1998. From my first oil change in my 2015 Challenger SRT392, I have been using Signature 0w40. Car runs smooth and quiet. MDS works perfectly, and I don’t ever worry about the job the oil is doing protecting my Big 392 HEMI. Can’t go wrong using any Amsoil product. I’m a customer for life.

Just love Amsoil! Been using their oil since 1998 without fail. I’m running this 0w30 in my 2014 HEMI Ram 1500 and in my 2016 Jeep Wrangler with the 3.6. I know I know, both call for 0w20. I say Bull on that. MDS runs perfectly in the HEMI and the Jeep can also benefit from that little bit more weight in the HOT Summer of Arizona. I’m a Amsoil customer for life.

amazing product. I’ve been using this for two vehicles that are Mercedes-Benz definitely can feel the performance and the reliability. Every time I drive I don’t feel afraid running my engine too hard, because I know the oil is the best specially from Project Farms who recommends your product from YouTube not even sponsored I wish he could be.

Will forever be a fan

It is Cleaning up the inside of the engine

Got the oil pressure up in my GMC. Love how long it lasts...

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.
