Customer Ratings & Reviews

I started using AMSOIL when the original name was Amzoil (after Albert Amatuzio)). Synthetics were a bit of a novelty back then. Since then, I’ve had vehicles that I’ve sold with over 300,000 miles on the odometer. They all used very little oil, eventually, and maintained above average fuel economy. The best of the best and well worth paying a bit more for. The long term cost has been significantly lower. AMSOIL passes the test of time.

You didn't have the oil filter I needed, again. Had to buy from a local parts store.

Superb technology and piece of mind when using this product.

I have been using this oil for years in my truck, cars, and motorcycles

Feels smoother and last longer. All I get for me and my wife’s vehicle

I love the product. And great delivery service. However, was unable to purchase AMSOIL filter due to being out of stock. Had to buy the WIX.

This oil is superior to all other brands ! Amazing product with great results

In my opinion, this is the best oil you can buy for your vehicle. I've been doing my oil and filter changes myself for the past 50 years and I've tried them all. You really can't beat Amsoil full synthetic oil. They're filters are excellent as well.

I use this 0w-20 in all three of my vehicles. Oil samples always come back looking great. Easy to order and arrives quickly.

This product is great, and all of the AMSOIL products are great. The oil filters they can’t seem to keep them in stock.

Improved engine noise.

I’ve always used azole and it’s never let me down. I love it.

Been using Signature 0w/20 in my MDX and girlfriends CRV. Oil samples at 15k intervals show very minimal wear metals and still outstanding viscosity . The CRV has the dilution issue and after the sample results it hardly affected the oil. 10k for the CRV from now on. Best oil to deal with dilution issues .

I've officially changed everything to amsoil!!coolant, oil, gear oil, radiator fluid, now only time will tell if it makes a difference!!

Truck runs quieter, engine even a little cooler running

Best oil on the market for my 2024 Ford Ranger Raptor direct injection twin turbo engine. For protection and wear this oil is my favorite.

Outstanding oil, which is worth the investment to maintain my motorcoach and generator. Very highly recommend!

Great product best oil !

Best oil I have ever used in my Cars. The oil holds up better and longer in the everyday use than any other. Love AMS OIL.

Great oil and always prompt delivery of products I buy on line. I can tell my truck runs smoother after switching to this oil.
