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
Bottom Line
Yes, I would recommend this to a friend.

Best oil

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.
Bottom Line
Yes, I would recommend this to a friend.

It’s very high performance for my minivan during highway driving over 85 miles per hour. It feel like the minivan has no friction and great momentum! Use it for few years now. It not up to 25k mile change interval but 5 k mile for my high mileage.
Been running Amsoil for many years. The FJ has 290K on it with no leaks and not one bolt has been removed from the engine for any repair. This oil works with 25K oil changes.
Always used this product on all my vehicles love all the guidelines especially with my turbos on my 2020 F150 Raptor would recommend this product for every one #1
Bottom Line
Yes, I would recommend this to a friend.

Been using Amsoil Signature Series 0W-30 pretty much since it came out. Used it in place of 5W-30 in my 1987 Toyota Tercel Station Wagon 4WD (250,000 miles at present) first. Now also in my 2013 Toyota Matrix AWD in lieu of the 0W-20 it calls for trying to prevent the oil consumption that engine is known for. So far over 145,000 miles with excellent gas mileage and no oil consumption* (1/2 quart of oil used several times around the 5500 mile mark). Not too shabby! I recommend it highly, but for "safety" reasons stick to your recommended oil viscosity. But of course - Amsoil

I have been using AMSOIL for 7 year. I use Amsoil for my Tundra and Dodge 2500 HD Diesel. I will never go back to using the standard oil that is sold at stores.
Bottom Line
Yes, I would recommend this to a friend.

This product is outstanding. I use Amsoil products in all of my vehicles, and have been for many years. I experience no lubrication related issues with my vehicles. I will always use Amsoil products in all of my vehicles.
