Customer Ratings & Reviews

Best you can get. Great service great shipping.

I bought this oil cause reviews said it was good for direct injected boosted engines. Ecoboost engines have issues with high mileage carbon build up so decided to give this a try to help combat it. Engine is noticeable more smooth and quiet so I ordered more for my coyote mustang.

Nothing is better than Amsoil oils for protecting your hard working pickup trucks!

I was always a mobile One fan but after doing research on Amsoil and buying a new muscle car I knew there was a better racing oil out there to use and I couldn’t be happier using Amsoil with all the benefits of lubrication that their oil provides !!!!!!!!

Use it in our SRX and makes the Engine run great!

Best prices on the web. Super-fast shipping! Great customer service!

Great product, this all I run and I’ve never experienced any build up or any oil-related issues. Highly recommend all AMSOIL products!

Engine runs smoother and cooler

My truck runs so smooth! I know that my engine is in good hands with Amsoil!

I've been using Amsoil XL for years now, we recently bought a van for our family and I wanted to see how XL held up in the vehicle after around 10,000kms. So I sent a sample to Blackstone to get analyzed, they determined that there was still more than enough lubricants and additives to prevent wear, and that the oil was holding up very well at that mileage. Keep in mind, this is XL, not Signature - so I assume Signature would be even better. That to say, I'm very happy with the product and it's great to know that it'll easily last 10,000kms between changes. Would definitely recommend :)

Great stuff, we’ll thought out.

First time using amsoil. So far I’m happy with it. Gonna be changing trans and diffs soon to all amsoil products.

We have converted one car to this product and have a 2nd suv to start in one month.

Once you have used Amsoil you can't go back to a lesser brand. It is the best at maintaining your vehicle's.

I can go more than 6k miles between oil changes and oil is still pretty clean. Great product!

Love the products! I use amsoil in everything that I can find on their list that I have. Not once have I had any trouble. It’s great to only change my oil once a year!

Great quality oil. Switched from Royal Purple which is good but noticed quieter engine operation with the Amsoil.

I purchased my truck in Dec. 2013, with 58K+ miles on the odometer. I have always used AMSOIL 5W20XL synthetic engine oil. This is the required viscosity oil for my 2007 Dodge Ram 1500 Quad Cab with the 5.7L HEMI. I now have 96K+ miles on the odometer. My truck uses about 1/2 quart of oil between oil changes. I also get good fuel mileage with my truck. I highly recommend the AMSOIL 5W20XL synthetic engine oil.

I ordered a complete kit from Amsoil which excluded, a filter and six quarts of oil to complete the oil change. I've done this with two of my vehicles so far. So simple. Will order again

This is great oil NS THE Quart bottles are easy to use. I also noticed that the engine is running smoother. Still looks clean after several miles.
