Customer Ratings & Reviews

Viscosity holds up amazingly especially in stop and go traffic. Glad i gave this oil a shot will continue to use from here on out. Would definitely recommend giving it a shot you won’t be disappointed

Have used Amzoil products for40 years and if you review various places that test motor oil you will find that Amzoil is at the top of the list on exceeding test result criteria to protect your engine. Lot of oils meet and exceed oil test requirements but Amzoil adds a little more protection than what is required of a motor oil.

Have had great results using AMSOIL and will never change. Excellent Products

excellent oil , lifter noise reduced dramatically, oil consumption excellent and boosted my mpg by 3 .

Best oil products on the market. Nothing even compares to how well my vehicles run than when I have amsoil in it. I use it in my truck, car, sxs and mower and will obviously continue to do so, awesome stuff.

Keypad the wife's Honda going great. Known quality, dependable

the best oil on the market, i trust all my machinery with it

the best oils on the market, second to none!!!!

Great stuff, with excellent engine protection and extended oil life!

This product is very good but the signature series is the top of the line!! I would recommend trying each series of Amsoil that best suits your liking. U can’t go wrong with any Amsoil product.

Been using for many years. Now that I am retired and do not drive as many miles as I used to, I do not need the best level. The 12K per year works great for both my car and truck. Thanks for the sale, five quarts no shipping charge. It was appreciated.

I use XL on my 2009 Toyota V6 Tacoma since 15K and never looked back. It keeps my engine running great along with other Amsoil products.

Good quality oil keeps my engine clean

Great product, I’ve been using this brand for 16 years and never had a problem.

Best 2 cycle oil I've used, They start better, Run Smoother, Smoke less and use exactly half as much oil. Great Product.

From previous experience most of the things you can't buy in the store is top of the line. This is one of them. Best oil ever in my opinion.

I used to use Mobil 1 motor oil exclusively but after seeing the the scar test results I’ve used amsoil ever since! That was 25 years ago..

Seems to hold up to the wear and tear of a Subaru Boxer Engine.
