Customer Ratings & Reviews

This oil is the best oil for a snowblower across various temperature ranges.

I have seen the oil analysis sheets for this product compared to others and if you want the best for your engine, this is it. By a large margin.

Great oil. 25k between oil changes. My engine knows the difference

Once again, amazing product. I've never experienced such a dramatic decrease in the sound of the engine. Ticks and clicks went away, sound is much more quiet, and everything is far smoother during excelleration.

I've been a car guy since the day I was born. I've built cars, restored cars, you name it. I've never experienced such a severe change in the sound of an engine just from changing the oil. My wife's Honda CRV ran like a normal Honda, little ticks and clicks that naturally happen from an engine. Nothing wrong with it, it's brand new, just your everyday sounds. But once I changed the oil, using AMSOIL Signature, the sound of the engine dramatically decreased, no more ticks and clicks, and the excelleration of the vehicle is so much smoother.

Been using AMSOIL for quite some time. I have a Honda, valves need adjusting every 15k miles. I find no staining of the aluminum, no sludge or wear of the camshaft - 126k. I can’t argue with that.

I would highly recommend Amsoil to any motorsports/car enthusiasts! First thing that caught my eye about their oil was their pride in not only the research and development, but the customer service too. I've been using their SAE 5w-30 for years now and have never had an issue. And I am very meticulous about taking care of my engines. My order usually processes and ships within a day or two. One thing that I find inconvenient is they are usually out of stock of my oil filter, so I have to out source for it. But it's not a big issue to me

Great products, been using them for years. However, it seems lately that I get a free shipping offer within a day or two of placing an order. Once or twice may be coincidence, but its very consistent lately. Enough so that I may be buying my oil locally from now own. js.

Best oil on the market in my opinion ! Used in all my vehicles and motorcycles

Well I finally broke down and decided to try Amsoil. I’m glad I did. I instantly noticed the engine ran quieter less ticking etc. The motor runs cooler as well. It is definitely going to be put in all my vehicles. Amsoil may be a little more expensive than other brands but it far exceeds other oils and last longer. Thanks Amsoil.

Great product. I have been using it for years!

I don't change my AMSOIL oil for anything, the best and the best for your car

Love the oil I sure would recommend it to everyone.

Been using Amsoil for years now. Always an easy experience, fast delivery and a good feeling knowing the quality and reputation of using Amsoil products. Would highly recommend to anyone.

I’m using this oil for my STI and Lexus ls430 . I have over 200000 miles on Lexus no oil added between oil changes.

I’m using this oil for my new Subaru.

Best available oil I believe

Best available oil

I run this in the summer in my '23 WRX. The 5w-30 offers better high temp protection than the 0w-20 I run in the winter months.

I use this in the winter in my '23 WRX. It's an excellent replacement for the OEM oil and far exceeds it as well. Superior protection and cold temp flow is extremely important up here where temps can run in the negatives frequently.
