Running XL 0W - 20 in a Toyota tundra It's works well

In my side x side and works great

Good, as always!

One can feel the difference in a free'r running engine with Amsoil lubricants

best oil on the market

This oil gives me the confidence that I can count on.

Great oil, will never use another brand. I do trust this oil. Does what it is designed for.

I have used this product for many years and I love it! It is very good quality.

This oil is really good, I use it in a Nissan car. Before the normal oil my car would burn in a part every 1000 miles. Now with this one it burned the same but in 1900 miles and using the air conditioning. So this oil is really good to use. I really recommend.

I've been using Amsoil for over a decade and have never had one issue with the quality.

My car runs smoother ever than before. I don't need to change my oil every 5k miles. With this product I can go over 10,000 miles or more.

Hi - I am running this is high mileage jeep (Florida) that per my Torque Lite / app & module the jeep is running 4-7' cooler since using this oil. the only way is less friction. again live in FL and on June day I changed oil I ran my jeep around block to warm oil before change and after oil change took same route and some highway and was actually several degrees warmer (late AM till afternoon heat) and just love this oil. NOTE - IF you live in cold areas I personally would not run 10/40 as 5W-30 flows better when cold. I just have always ran thicker oil in summer heat in FL

This is my second year with this product in my SUV's and they are running like new.

Good

Best oil in the business in my opinion. I've been using for years. You get longer change intervals, no sludge and great performance!

Great oil, even after 10,000 km engine runs smoother

Great oil in my V10 Ford powered motor home.

The best! Hope the product is never discontinued!

Great oil I use it in my 15 wrangler, no complaints.
