Bought for my new used Honda CIvic with 60K miles. Oil life is at 70% now. Bought this in advance for my next oil change. Waiting for the Amsoil oil filters to come back in stock. In the meantime, the product was delivered immediately. Can't wait to try it. My son swears by Amsoil.
After people commenting how much quieter and better running their engines seem using this compared to other premium brands I thought I would give it a try. Put it in my 2021 Tundra and didn't notice engine or drivetrain or anything smoother or quieter than what was already in there(a major oil company synthetic). I am sure it is doing an excellent job lubricating but I notice no difference in how engine feels or behaves at startup, accelerating or anything. I generally change my oil at 5000 miles so SS certainly overkill but wanted to see if the hype was real. Also I don't understand why this doesn't carry an API License - I'm sure it meets the spec but why not Licensed? Won't buy this product again but may look at the API Licensed oil that you sell.
Bottom Line
No, I would not recommend this to a friend.

I had been using Pennzoil Ultra prior to using Amsoil so I'm starting from a great oil. I believe the Amsoil product is slightly better than Pennzoil Ultra and I have had great success with Amsoil in my 2017 Jeep Grand Cherokee. I also used it in my 2012 Chrysler SRT-8 (5-W40 grade) with great success also. I feel this is true synthetic oil offering better shear and wear protection than all others. It's worth the price difference to me.
Bottom Line
Yes, I would recommend this to a friend.

Ive been using Amsoil in our vehicles for years. It is so convenient to only have to change oil and filter once a year. By skipping the extra oil and filter changes each year I am actually saving money. What is most important is saving wear and tear on the engines! Keep up the great work, AMSOIL!!
Bottom Line
Yes, I would recommend this to a friend.

Far superior product

Been using Amsoil, exclusively, for decades, in many vehicles. Never one oil related issue. Currently have a 2020 Ram 2500 6.4 gas engine. Those engines are known for cam/lifter issues. Most "tick", some experience cam and/or lifter failure. My truck has 21k miles on it so far. I change oil & filter every 7k miles. Engine is not showing any sign of typical failure. No tick whatsoever. I have been an Amsoil dealer for 20+ years, and mostly only for my own needs. Amsoil is the best IMO. Also, check out PROJECT FARM on YouTube if you need further proof.
Definitely worth using if you wish to extend the life of your engine. I've used other motor oils in my 2016 Power Wagon, but I won't use them any longer regardless of what the shop recommends. My truck has a little over 130,000 thousand miles and she still sounds and runs just like she did when she was new.
Just open the box and examine the filter. You will know why you’ll never waste money on anyone else’s filter again. Durable seal and solid construction. It stands out.
Bottom Line
Yes, I would recommend this to a friend.

Honestly, truly the best. Noticeable difference in engine.

I'll put it like this. When I buy my dream car I will swap all fluids to amsoil from day one. YOU WILL NOT BE DISAPPOINTED.
I have used OW-20 Signature Series oil in my truck ever since I purchased my Truck back in 2014. That oil has never failed me. Every time I change at 15k intervals, it continues to look like new still. I wish someone turned me onto Amsoil years ago.
Bottom Line
Yes, I would recommend this to a friend.

Amazing Oil

Best oil out there period, viscosity holds up the best of all the other synthetics
I have friends who have used nothing but AMSOIL products in their vehicles and have gotten hundreds of thousands of miles out of them. This is the first vehicle I've owned where I have started with the oil and air filters from brand new. When I get more miles on my truck, I plan to replace all of the fluids with AMSOIL products - transfer case, transmission, etc. It's a little pricey, but it's actually saving me money when I only have to change the oil at 25,000 miles. When I place my order, it's been pretty incredible that a box arrives at my door the very next day!
As soon as I paid off my Lexus 2012 350RX,I stopped taking my car to the dealer for maintenance, but also I wanted to make sure that I'm getting the best protection for this engine, I've been using Amsoil in a 1998 Mitsubishi Montero sport and had no problems at all with internal parts in that engine, so it was a no breading to keep on using Amsoil in this Lexus, great product, I believe in good maintenance better that repairs, and this product hasn't let me down.
Been using this in my 2015 Kia and running it for 25,000 miles between changes. Oil doesn’t look bad at change and that assures me it’s doing the job.
