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.

Best oil used by far

I’ve been using Amsoil ever since it hit the market. I use it in everything I own that requires oil. I also use their filters, I do so because I believe in their products. There are many choices to pick from, if you want the best you can get by Amsoil.

This is the best motor oil ever. I have my oil changed at regular intervals but I really don't need to because the oil looks the same as when I first put it in. I have my oil changed every six thousand miles and it looks just like I got it out of the bottle. This oil is fantastic.

I HAVE A 2014 FJ CRUISER I USE AMSOIL IN EVERY FILL PORT IN THE VEHICLE... ITS THE BEST THERE IS HANDS DOWN...

Used this oil from day one of ownership, not touched the engine other than cam belt, water pump etc

Great product as always.

This is my go to oil. I've used it for years. My vehicles get hard use and I want them protected.

We have used Amsoil in our cars for years. My truck will be turning 240,000 miles tomorrow. Not only does it still run like new but it doesn't even leak. I believe Amsoil ( and some basic preventive maintenance )is the reason it is still going strong.

Highly recommend 2002 Corvette runs like new.

Good 👍

Been using this while since 2015…. previous before Amsoil was royal purple, and they did not meet the manufacturers specs went to Amsoil and never looked back.

Been using xl in my ram hemi since I bought it switched to signature since the new xl is formulated close to signature, might as well use the top shelf product

The only problem with the gal container should be increased to 5qt and not 4 this would be great. That seems to be the new standard in buying oil. Think about it

The best oil for the money. Only other ones I would consider are Redline, or Motul 300v(for racing). But Amsoil is better value. Only thing that can be improved is if it comes in 5 quart containers for even more value.

I use this on my 2019 Ranger 4cyl turbo with no issues. Even thou it is used as lite duty transportation for my wife. I feel better using Amsoil.
