Best oil to quiet a top end.

Has helped keep my 5.7L Hemi happy, and on the road. Oil changes every 3 months at 7500 miles, and it stopped using oil after I switched to AMSOil. 125K on the engine now.
We've used this oil in our Explorer Sport since it was new. Eight years and counting and no issues of course. I'm sure there are other good oils out there but I consider Amsoil to be the best. It's all we use in all of our vehicles.
This is the only oil we've used in our F-150 since we bought it. Over 50k miles, including a lot of boat and camper towing and it's smooth as ever. In my opinion you can't do better than Amsoil.
Bottom Line
Yes, I would recommend this to a friend.

Why buy anything else

You may get a cheaper oil. But that is what you get for your money, cheap. Amsoil is top notch. Used in everything. Since used for the last 25 years I have not lost a motor, Trans, transfercase and differential.
Bottom Line
Yes, I would recommend this to a friend.

Best of Best when it comes to oil

Put this oil in all my lawn Mower and tiller had my push Mower over 17 years runs just like it did when I first bought it
Our fuel mileage went up a little bit after switching over to Amsoil Motor Oil. With the high cost of vehicles these days, why wouldn’t you use the best oil? Our cars run smooth and quiet and have never been back to the dealer for anything since the day we bought them. We are huge fans of the entire product line!
Everything is just better with amsoil
Run longer with confidence I been using it on my lightly modified 2015 jeep wrangler jku with 35s I feel I’ll be getting the most out of my Jeep for years to come.
I started using Amsoil in the early 80's, at first was kind of skeptical because there was nothing else like it. Over the years Amsoil has gained my 100% trust. I've used their products in my cars, trucks, motorcycles, yard equipment, and emergency generators. Never once have I had the first issue or a question in my mind that it wasn't living up to it's reputation. Amsoil always seems to be ahead of the game when it comes to updating to new standards, sometimes it takes off the shelf oil months to meet the new standards. If I order over the weekend it's on my doorstep Tuesday. No need to run from store to store looking for a gear oil, transmission fluid, coolant, or any of that kind of stuff to service you're vehicle or equipment, Amsoil pretty much has it all.
Bottom Line
Yes, I would recommend this to a friend.

I Love amsoil

I changed oil brands from Mobile 1 to amsoil. I could feel the change in power and fuel mileage almost immediately. Love it..
Have been using this Signature 0w-30 in my Alfa Stelvio since it went in for it's first required
service. The dealer service writer was ekeptical that I was not allowing not using their oil but the attending mechanic quickly informed the service writer that this was probably the best aftermarket addition for these vehicles. I also used the AMZOIL filter and have been changing the oil at 7500 miles. Have 30K now and the oil comes out almost clear during changes.
