I have been a user of AmsOil for sometime. Even though, I have no proof that it is better than any other, except for photos and videos provided by the company. I have not noticed any improvement in gas mileage, idle or oil pressure improvement. It does, however, make me feel better!
I am using AMSOIL from the first oil change. I have used it before in my OHV vehicles with great results. Right off the jump I see oil pressure up a little and oil Temps down. Seems to be getting a couple tenths better fuel mileage as well.
Bottom Line
Yes, I would recommend this to a friend.

Outstanding quality

I have been using Amsoil products for vehicle for the past 3 years. I have seen my car engine running smooth and quiet.
If there is a better oil out there, I don't know what it is. Facilitates cold weather starts; keeps engines clean and running like the day they were built. Expect to put hundreds of thousands of miles on most engines, using this oil, a good filter and doing regular, extended oil changes. Great stuff!
Ran this for 170k in a Subaru. Pulled the motor for the head gasket repair. It was actually incredible how clean the inside of the motor was. Highly recommend for longer intervals.
Bottom Line
Yes, I would recommend this to a friend.

I’m getting about 75 miles further on a tank of gas in my economy car, I’m now putting AMSOIL synthetic oil in my Harley Davidson as well as my F 250 Powerstroke, I wish I would’ve known about this oil much earlier.
Bottom Line
Yes, I would recommend this to a friend.

Excellent oil but the price is a bit higher than it's comp
Wonderful product, just a bit better than Mobile one but the price is higher, I love the Amsoil oil filters but they do not have one for all makes of cars. Wish the price would adjust as their competitors are closing the gap on quality at 2/3 the price.
Rapid shipping and great product. Looking for 200,000 miles
Bottom Line
Yes, I would recommend this to a friend.

Excellent oil, still looked good after one year in my crankcase. Use this type in my Vette. Please start marketing it in gallon or 5 qt jugs, since my car takes 10 qts.
Every time I order from Amsoil it's an easy process and customer service has always been excellent. The quality of the oil is almost secondary to the service but it is the best you can you get. Will always order from them for my GT350 and can't recommend enough.
Bottom Line
Yes, I would recommend this to a friend.

I been using this amsoil 50k my truck runs like new 👍 👌
I have used amsoil engine oil for decades. It has always preformed well for me. I like to keep my vehicle for a long time. I put a lot of miles on my cars. Amsoil engine oil has more of the antiwear additives and detergents that going to keep you vehicle’s running longer. Paired with the right filter isn’t a home run in my book. Try it.
