Great product have have had no problems. If I put more miles per year I would use ASL

Good oil

Again I discovered Amsoil approximately 15 years ago, I ran it in my Dodge Durango, & My Silverado. I now I'll run it in my Mazda 6. There's a definite extra smoothness in the engine while running Amsoil vs would I formally Grande I run Angela and all my four-wheel and two wheeled vehicles also run many other Amsoil products I can't say enough about it.

Second time using this oil and like it. Again delivered next day! ??

Only oil I use

Top quality oil product! I use Amsoil in all my vehicles both on and off-road. It's outstanding how Amsoil's synthetic blend oils stand up to thermal breakdown. I typically replace my vehicles engine oil after 10,000 km...and it comes out darn near the colour it went in. Even in my Duramax!

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
