i have a 2022 Sentra i bought new ..The best mpg i could get was 37-39,,until i switched to AMSOIL!!!! I am amazed now I am getting 41--44 mpg. And the very best I've got was 45.3 MPG .. It's amazing so now all my vehicles get it.

This signature series motor oil has let me extend my interval in between oil changes and I likethe detergent in it that keeps my engine protected and running smooth.

Put this in my wife’s jeep and no more lifter noise. This is worth it, it doesn’t matter what it cost, if it keeps the motor running longer it is worth it.

My 2005 Camry runs very smooth with 240000 miles and a 4cyl. too!

I purchased this oil to use in my 2018 Chrysler Pacifica and since using I find that my engine is much more quiet when starting cold. I highly recommend it.

I've been using only Amsoil in my cars since 2000 because it's the best. Nothing more to say!

Based on testing and personal experience, this is the best oil on the market. I love that I only have to do two oil changes a year given the high miles one of our vehicles is driven each year. Our other cars go a year between oil changes.

Great 👍

I am running this oil in my Toyota Tacoma with a V6 and it does what it is advertised to do. i will leave it at that but will lastly say, my engine stays clean internally and that says a lot.

I really like this oil and wouldn't put anything else into my engines. Add some militech or best oil(?) and get the most out of a refill. Just be sure not to let it run too long otherwise the oil thickens as it ages. Well, it did in my 454SS Chevy truck running a heavier viscosity oil so take that with a grain of salt. Other than that it is a good buy.

Great oil. It meets the Chrysler specifications and my 6.4 Hemi sounds happy with it. I occasionally have it lab tested during a change and the results are always phenomenal.

Excellent performance and protection

Started using in my father’s car … which is garage kept 90% of its life… mint 12 year old Chrysler 300 under 10, 000 miles , switch over to Amsoil signature series. With a wix oil filter… Runs smooth as glass … A+ I’ve been using this product Amsoil signature oil 5w 20w in my Super duty for 18 years … motor runs incredibly smooth n gas efficiency due to this oil … it’s my choice over all others.

I believe in the products, all have worked well for me

My three automobiles all take 0W-20 Signature Series Synthetic Oil. I am shocked that all of my oil changes are unbelievable! Each time I have drained the oil, I could still see the life left in the oil. I change all of my oil at 10k, on the dot every time. There is not better oil to use!!

Great stuff. Slight increase in oil pressure and motor sounds noticeably quieter.

Product came as described. Now just to put it to the test for 25K Miles.

I believe that this is the best oil you can buy. You can tell how long it lasts in most engines by keeping an eye on the oil level, generally as the oil breaks down and becomes contaminated your engine will start to consume oil, that's when it's time to change it, so keep an eye on it especially when the mileage is over 10000 km's and change it when you start to see any sign of consumption, this varies with every vehicle. The oil is so good that you will notice your engine runs smoother and fuel economy and performance is maximized, I love this oil so much that it's not worth my time and effort to install anything else, Also use the Amsoil oil filter for extended oil drain intervals.

I use AMSOIL in all my vehicles and noticed better performance, gas millage, and my engines run cooler. Keep in mind when ordering the large jug is 4 qts. This product is the best for what you get.

I use AMSOIL in all my vehicles and compared other brands over the years and you can't compete with what this motor oil offers. I totally care about my engines and there performance and longevity.
