Good oil!

You can actually hear and feel the difference in the way the Engine runs. Great oil!!

I just turned 200k miles on my 02 Chevy truck. I’ve used Amsoil products from bumper to bumper and truck still running like new. Thank you Amsoil

The oil is very good.

I have used this oil continuously since 1996 in all of my vehicles. I lived in Alaska but moved to Delaware in 2018. Shipping has always been timely and reasonable. I tend to change the oil every 6,000 miles in the car, and once per year in the truck. (2011 Dodge.) The latest test showed no loss of compression. I could not be more pleased.

Been using Amsoil for over 30 years. Been using this particular oil in a 2005 vehicle since new on a 10k mile change schedule. It now has 240k miles, uses absolutely no oil between changes, sounds and runs like new and has never had an internal engine issue. What else can I say!

First time trying this type of oil on my 2018 Forester XT and so far is doing a great job.

This product is great! Increased my gas mileage smoothed out my idle and is just an over all great product I will use nothing else from now on

I appreciate the consistency in their product shipping over getting me oil and filter quickly and without hassle. Much thanks for the reliability

I'm new to amsoil but after changing all my fluids to amsoil i believe the car seems to run much smoother, and amsoil is very organized and easy to order from, fast shipping

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 :)
