Customer Ratings & Reviews

We had to do an engine swap and bought generic oil after install to test it out. Once it was driven a while we put in amsoil and the oil pressure increased significantly. That's why all of our equipment from compressors to trucks only gets amsoil. They are unmatched in every field.

After seeing how it makes my old truck run, I decided to use this product in my Jeep

It helps my 27 year old truck with 141,000 run better, and offers great engine protection.

Car gained power and hasn't used a drop of oil. Seems to be running cooler as well. Very impressive.

Been using for a while great product have recommended to several people .

So far all of Amsoil products I've used are top notch and very quick shipping will continue to use there products

It's a very good oil engine runs smoother and a little better fuel mileage

Quality hands down better than other brands

Been using all sorts of Amsoil products for years. Wanted the best for all my cars and toys and Amsoil is the only choice for that. I am a long time customer and a happy one at that. From my Supercharged Mustang to my daily drivers and my track toy with a built motor, I only use Amsoil. Seen great results with it over the years, being a certified technician who works on high end German cars for a living, a quality oil goes a long way with a vehicle. If you’re on the fence, do yourself a favor and get the best.

The engine's run really good on this stuff and oil stays cleaner longer than oils you buy on the self at your store or choice

This is the only oil I run in every single thing I own including the lawn mower. I love this oil.

Great product, I highly recommend

This is my go to oil. I stick by OE schedule changes with this XL oil. I trust Amsoil with all my vehicles. The deliveries are always quick.

I have grown very fond of this and all the AMSOIL product. Best lubes that I have found and will continue feeding my vehicles with it. My daily driver get 4K a month and this stuff is fantastic at keeping the internals lubed, clean and running great.

I run this in my RZR XP TURBO in the desert areas around Bullhead City. It gets pretty warm there but when I change oil, the used AMSOIL drains out clear and very little material stuck to the drain magnet.

Awesome oil. Use this oil in all my engines.

I have been using this product for the last 4 years and have had nothing but great things to say! Of course like many others I have used all the other competitors (Mobil 1, Pensoil, Castrol, Royal Purple, etc.). The first time I did an oil change with Amsoil, I was shocked to find that the dipstick still yielded golden oil after 2,000 miles! All the competitors would have been dark brown by then! Nothing but great things to say and will be using Amsoil for years to come!

This oil works great, protects for life! Totally worth the cost.

Wouldn’t consider another oil. Used in my 2014 3.5 F150 and in my current 2020 F150 3.5 F150. Engine is quiet even on a-30 cold start and maintains good performance in 100 degree weather. I tow a 24’ boat or an 18’ enclosed trailer. The boat weighs about 6000# on trailer and the 18’ trailer has been loaded to over 8000#. I’ve never had oil consumption or any indication of oil breakdown. BTW, I also use Amsoil European motorcycle oil and gear lubricant in my late model bikes.

I have always used this in my wife Toyota. I trust AMSOIL.
