Customer Ratings & Reviews

The day I bought my 2005 F250 home I dumped the stock oil and refilled with Amsoil 0W20 and a EAO11 amsoil filter. That was 16 years ago and it still going strong. I would never use any thing else.

I have been using this since the day I bought my Ford Explorer and have never had a problem. Bought the truck home and dumped the stock oil and refilled with Amsoil 5W20 and a Amsoil AEO17 filter that was 3 years ago and will never use anything else.

Have used amsoil in all my vehicles for over 30 years , and have never had problems, if you are trying to decide if you should use amsoil its a no brainer , your car will thank you for years!!

I used Amsoil ever since I heard of it. Last time I changed my oil was in January 2020 and I just changed it in March 2021. Stuff works great. Shipping was super fast, only a couple days!

Haven't used yet.

This oil has better protection and can be used for 25 thousand miles between changes with the right filter

I've used this oil in more then one I've owned and will keep using it ...

Quality oil as usual.

Excellent products. Still currently begging for some decals. Seems odd since I am surrounded by vehicles with Amsoil products and wearing an Amsoil tshirt and looking at a huge Amsoil vinyl banner in my shop (I bought both). I have never asked for anything. Maybe I am just the little guy. It irks me.

Twice, out of curiosity, I sent samples to a lab for analysis after 16K miles of use. Both times all viscosity and additive levels showed I could run the oil for several thousand more miles. That is with towing, highway and local use mix. Contamination levels also lower than tolerances thanks to amsoil filter. I change oil no more than once a year. Sometimes almost 2 years in my 2002 Toyota Sequoia. Great products.

Use for my Toyota Tundra Truck V8 change one a year due to low mileage. Works great no oil usage and provides great protection.

My first time using this particular product and I am blown away by its performance. Within just the first few minutes of using this product. I immediately noticed my engine idling much smoother and it sounded better harmonically as well. Like it was more in tune and moving freer. I've never had automotive product work so well, ever. Great job AMSOil team. In my opinion well worth the money. I was using Subaru premium synthetic motor oil for the past 2 years with full service included. My vehicle only has about 20K on it and is very well kept. And I still noticed a tremendous difference. Bravo Zulu

I put this oil in my 2017 Ram. I had 90,000 miles on it. Now it has 93,000 on it. Compared to Penzoil Platinum oil when I put a few thousand miles on it, Amsoil still looks new. I plan on putting 5,000 more miles on it. I'll see how it looks then.

Keeps my engine running clean and smooth!

Great oil and competitively priced to other synthetics if you are a preferred customer.

Great

I have been using Amsoil in all my vehicles for the past 10 years and engines run smooth and stay clean.

best oil

2500 miles on a GDI turbo KIA Forte - I drive my car hard and the oil still looks and feels like I just put it in.

I've been using this 0w-40 in an engine that normally calls for 5w-30 weight oil. It gives the easier running when engine is warming to full temperature, and lowers oil consumption when engine is fully warmed up. I started using this weight at 220K. Now the vehicle has 278K. Still runs very good!
