Customer Ratings & Reviews

Car runs extremely smooth and gets better mpg’s.

Great oil for gas engines, never have to add oil between changes. Even at 20,000 plus miles.

I used to use Mobil One for many years. No regrets but several friends told me about Amsoil so I thought I’d give it a try. Did not disappoint. Extremely satisfied I made the switch. I’m especially impressed with the product line of other lubricants Amsoil has to offer. I’m a fan!!!

I have used synthetic oils is my personal trucks since 2004. Amsoil Signature Series 5W-20 is the best synthetic oil that I have ever used. I would recommend Amsoil products to anyone who wants to ensure that they are protecting their vehicles to the max. Thanks Amsoil ! KMurph Calvary, Ga.

2017 Hyundai Santa Fe and 2005 Dodge Magnum with the hemi. Motors are so clean and smooth running with this oil I will never switch. When the wife notices how nice they run with this oil that speaks volumes! Lol

The best quality motor oil in the market. No one comes closer. The leader in synthetic.

works as good if not better than advertised, always has.

Amsoil is the best oil I use it in all my vehicles love the long drain intervals

The best oil I have ever used it actually lowered my engine temp and stop lifter chatter at start up

The best oil!!! Great service and fast shipping! Thanks, Jim.

Amsoil’s the only oil I’ll ever use in any motor.

This is the best Oil Available I have been using this oil for many years and it is the best

I ordered this for my car, it arrived quickly. I used this for the past two oil changes and it comes out looking very clean.

great oil

Love the oil use it in all my cars.

I used this oil for my two cars. The replacement interval of 25000 miles or 1 year, help me save money. I use to go to the garage for my oil/filter changes a least four times a year. 85$ per visit by 8 times (2 cars). Make the calculation $$$$$ Drop. :)

I've tried other so-called good Oil but your Oil is the Best Oil Money Can Buy!!

Changed oil and filter on ‘13 SS looking forward to a long relationship with Amsoil thank you for the fast and easy shipping

Not the cheapest, but what is anymore. Pulled my cam cover to replace a gasket. Were talking new motor clean .I have 180,000 miles on my Toyota. Wth this oil maybe another 180,000. Still runs great. Still cheaper than a new motor.

Cant go wrong with AMSoil with this day and age engines which you see force induction more frequently. And maintenance playing a bigger role on maintaining performance of every component. My decision was based on my friends always using this over the competition until i pulled the trigger and honestly, im not going back.
