Customer Ratings & Reviews

I recently purchased a brand new 2024 F-150 5.0 4x4. I ran the factory oil for the first 1000 miles and then switched to AMSOIL Signature Series Full Synthetic. I will soon be changing my transmission fluid to AMSOIL as well. From its first fluid change to its very last, my truck will only get the best! AMSOIL.

Use nothing else. You can go for 10-15k and the oil comes out clean. Most importantly it doesn’t brake down and continues to protect. We have an ‘06 Civic and she runs like a champ on this

All the AMSoil products are excellent. There is no substitute for their quality. The oil coupled with an AMSoil engine flush and AMSoil filter will keep running smooth for years. We have a ‘06 Honda civic with over 200K miles and she runs like new. Ourfour other vehicles love the AMSoil just as much and run perfectly. Thank you AMSoil

All good

Oil came as described and got a free magnet dish. Wish I would have gotten decal(s) to throw on the window. Happy with product so far

Been using it since first oil change in 2007 Mountaineer 4.6 3V. Just passed 256,000. No issues and runs like new.

I have a 2016 Jeep JKU Sahara 75th Anniversary Edition. I bought the Jeep when it came off lease because the previous owner had meticulous service records through his dealership. On my first service, I switched it to AMSOIL and never looked back. I do my oil/filter service annually because I generally only put around 5,000 miles a year. With the AMSOIL and a Wix XP filter, I never have a worry.

I would definitely recommend this oil and all there products to anyone.

Great product, better quality than dealership.

I’ve heard good things about amsoil and just bought a 2021 f150 with 20000 miles and wanted to try this product. I wish I had taken an oil sample prior this oil change but will keep updating to let you know how I make out using AMSOIL. Shipping was outstanding. THANK YOU

I have a vehicle with very high mileage that I plan on driving until the vehicle wears out. My mechanic turned me onto this oil. I’ve never been happier with the results.

I have ran this oil in my 2019 Jeep Grand Cherokee V-6 engine, over 85K miles and runs like new.

I'm an Extremely satisfied customer and I would, and have recommended Amsiol products to many others.,so if anyone is cares for their vehicles engine like I do I highly recommend doing your research on head to head testing of Amsiol products against other top brands to see for yourself the results.,A high Quality oil is the lifeblood of your engine. Amsoil is the best.

Been running AMSOIL since I got the car. Had the oil tested by blackstone after every oil change and under the interval that I use the oil holds its viscosity with plenty of tbn left. The car idles and pulls smoother. Planing on moving to the 5w-30 after winter.

Don't write many reviews but this product deserves it. I dive a 23 Jeep wrangler JL. I have been using this product since my first oil change. I believe it is by far the best oil for the longevity of my Jeep, and I hold on to vehicles for a very, very long time. I believe in it so much that I never have used my dealer free lifetime oil changes because they refuse to use any other oil but their own Mopar brand. Imagine that. Free vs. paying a premium price for Amsoil plus cost of the oil change. Oh, I almost forgot that I use their filter as well. No more K&N. Yup, I'll do it for the life of my Jeep!

Best oil in the market

As an aviation professional, I know the importance of preventative maintenance. Amsoil seems to stay cleaner longer than other quality oils. I use it in all my vehicles.

Love amsoil !

Used this Signature Series 5W30 oil exclusively in a 2006 Scion xB with the 1NZFE engine in it. It went 230,000 without a hitch before the Maine winters destroyed the rear suspension components to the point where it was not able to be saved. Had I thought to rust proof this, I'm convinced that I would have put over 400,000 on it or more. Shame on me. Currently running it in a 6.0L Vortec-powered 2013 Silverado 2500 HD that runs about one a week but when it's running, it's being worked hard pulling my diesel tractor and hauling firewood. I love knowing that I've got insurance in the crankcase. Running Signature Series 0W20 exclusively in my Subaru and Mitsubishi and both engines are running flawlessly with higher miles and no oil consumption whatsoever.

This is the best and most durable full synthetic oil, for all my vehicles! Really quiets the engine down, as well
