I bought this for my Armada with 159k+ miles since I wanted to try to make it last as long as possible. Before using this oil, the vehicle would consume about half a quart after 2000 miles. Now, it’s still full after 1500 miles! The lack of adding oil plus the longevity of SS saves me money, just with a higher upfront cost compared to other oils (less overall cost as I can go 15k+ miles 😁)

Amsoil is the best in the market

Been using this oil along with the dual filter bypass kit on my 93 Volvo 240 wagon for the past 12 years. I keep the flame trap clean and check the oil separator every once in a while. Wagon keeps rolling. I keep smiling. Thank you.

My vehicle seems to run a lot smoother and accelerate a lot better. I've told my friends about this product and how much I love it thank you

Have been using Amsoil products now for 10 years and have never let me down . Had 160k on last Ram , now 121k on this one and only oil I’ve ever used.

Replaced factory Mobil 1 at 1st oil change, Chevy Silverado is going on 17 years and Dodge Charger SRT8 going on 15 years. Only the best.

I’ve used this in 2 vehicles now and never had a issue

The best oil I have tried. and I have tried them all over the years

I purchased a used car which required this 0W20 oil. I have used AMSOIL for about 30 years and have never rebuilt or replaced a engine. I easily purchased the AMSOIL product and will continue to use AMSOIL products.

Great product for cold flow and hot flow. Quiets your engine. Has high detergents to keep your engine clean inside.

Well, I purchased a unicorn of a car to me. 2013 Honda Fit with 12k miles in December of 2020. Switched to Amsoil ss at 16k. Mileage was around 33mpg. Highs of 34.5. Low of 32.5 After Amsoil with Amsoil filter, I am now getting 31.5mpg. I talked to a few Amsoil dealers, they are speechless as to why. I need to switch to Pennzoil or something because this isn’t good results after 600 miles . Maybe the cost of extra protection?? 🤷‍♂️ idk

I don’t fell any difference between cheaper oil and amsoil same as cheap oil after 4000 miles oil get black,I don’t know how it’s gonna make even 10000 miles.engine sounds the same no difference in mpg at all.I try cuz I hear all the benefits of the oil,but in real life it’s only a bubble!sorry to tell you that but I was expecting it to be more effective at least keep light color longer then 4000 miles. I feel like I just paid 2x more for same oil

Been using Amsoil since 2018.. awesome oil.

I switched to this when my 2011 GMC Denali ticked over 250kms. I feel this is an excellent upgrade to any higher mileage 5w30 engine. Engine loves it.

Been using amsoil for 10 years wonderful products thanks

I’ve used the Signature oil in my old 2001 Chevrolet Silverado (5w30); the 0w20 in my old 2012 Camry hybrid and now my 2020 Honda Accord hybrid. In the Toyota, I changed oil once a year. I experienced an increase of about 1MPG. I expect it will perform equally as well in my new Honda. My son now has the Toyota and is also using Signature 0w20. No fuss, no muss. Change it once a year and let AMSOIL care for your engine.
