Customer Ratings & Reviews

I use Amsoil in all of my vehicles. Excellent Product. 🇺🇸 made in the USA.

This is motor oil at it’s best. Very good properties and performance.

I've always liked amsoil. Ordering takes some effort, especially when you order and don't recieve the full order. I never recieved the free shop towels with my order even though the packaging said item one of two.

Amsoil is a consistently superior product.

Regardless of what type of vehicle you own. If your vehicle is designed to use this weight of oil by the manufacturer, then you are exceeding there recommendations for your warranty. Most of all your exceeding your own expectations and then some everytime you change your oil. Even if you go way over on your oil change. You don't have to worry, cause your using Amsoil.

Easy ordering. Quality service and product.

Ran oil 2019 Subaru on it since day one and runs perfect. Oils hardly even broken down at all @10,000km oil checks. Well worth the little extra to get the best oil.

I like it and the convenience of ordering online. Fuel economy wise I can't tell any difference.

I have been using signature series for many years now and have always had outstanding performance with it. Best thing about it is its mileage interval for changing; this ultimately saves me time and money. I have a 23 year old vehicle with no oil leaks with little to no usage between oil changes.

I bought my 2010 Lancer Ralliart new and have used Amsoil signature series 5w-30 oil the entire time I have owned the car. I order it on the internet and bring it to the dealership with me when I do the regular service intervals. My car has never had any issues. I would recommend this product for any turbo car for sure.

Always does great.

The best fully synthetic oil money can buy. Second to none

Used this product for over 17 years and have found it to be all, if not more than, it claims to be, an excellent product. My vehicles run smoother and cooler using Amsoil Signature oil.

I have a built genV l86. And have been running Amsoil sense. This oil contain the products needed for long bearing and cam life life. So far 10,000 miles on my 540hp 6.2 and three oil changes it’s a real comfort to see the oil draining out about as clean as when it was put in. Sweet

Been using this in both our Chevys. So far so good. We use Amsoil in all our vehicles.

OW-40 is what factory recommends for my 2016 Power Wagon. Been using this since first oil change at 4000 miles. No engine issues yet.

I have used since new and it runs like new. Used these oils in all my cars and never had any engine issues including no leaks..

Love this oil. Have a 2014 Ram Hemi 5.7 and don't hear lifter noise now that Iam using AMSOIL. 5 thumbs up!!

No complaints. I use 5w/30 Sig series in my 2004 Mustang Cobra that sees mostly track day / HPDE sessions. I also use this in my 17 STI, and in my 99 Ford ranger. I have not done an oil analysis yet but as of now i have not see any excess metal in my oil once drained or in my PCV catch cans. Will keep using.

been useing amsoil for over two years in all my cars and trucks couldnt be more happier with product
