I will never go back to purchasing from big box stores again...Amsoil provides a premium product with premium service and delivery... it's all that I run in our 2018 4runner, 19 Tundra, 18 Scatpack Charger.
I had 12,000 mile oil tested and the results were surprising as to how good the oil still was.
I’ve used this oil for 4 years and my engine has never run better and uses no oil.
The oil seems to be doing it's job. Engine sounds the same and runs the same, but I have noticed slightly better fuel mileage running this oil. Delivered promptly and intact.
Bottom Line
Yes, I would recommend this to a friend.

Heard about Amsoil for years, but never used. About 5 years ago I tried it, and haven't looked back. Run in both cars, and my motorcycle.
I had to settle for the high mileage instead of the signature blend which is my usual oil. But I've been running it now for about a month in my daily driver (Ram 1500) and I do anywhere from 50-100 miles a day. Steep grades, mountainous highway driving, high desert heat upwards of +100°. And this oil has performed better than any other "synthetic" oil you buy at one of the generic parts stores. I don't notice a big difference between the signature series and this one, but I like them both and so does my truck. Last oil change, my oil still looked like it had plenty of life left in it. Which is a good sign. And when I added the new oil (high mileage series) it made my engine run so smooth and quiet. Can't wait for my next oil change when I go back to the signature series! Amsoil for life!
Bottom Line
Yes, I would recommend this to a friend.
