Customer Ratings & Reviews

Have used Amsoil products for years now and they are great products.

Made by engine run faster than like it used to be. Worth the price.

I have been using AMSOIL Signature Series Oil for over 2 decades in several different cars. The results have been outstanding. My current car has 300,000 miles and does not use any oil between changes which I perform at intervals of 15,000 miles to correspond with the oil filter interval, although this oil is rated to last longer. There is no sludge build up within the engine as well. On all my new vehicles I changed to AMSOIL at 1,000 miles. I highly recommend AMSOIL to anyone who wishes to keep their engine running well for many miles.

New truck 5.0, best oil I have ever used!

Love this oil don't have the engine tick anymore

I have many many Amsoil products on my lubricants shelf and have found them to be outstanding ranging from commercial diesel to personal autos.

Great oil use it in all of my vehicles.

I don't drive the vehicle as much as I used to. Oil volatility is minimal, thus I never had to top up the oil before change. Gives superior gas milage and idles very smooth. Flows very quick, and worming up is not necessary during winter months. You will feel the difference if you use it for the first time. If driven hard, engine performs effortlessly. I own both Honda and Acura and I never used anything but Amsoil except what came with the car till first oil change. I have converted all my vehicle fluids to Amsoil product.

great

Good quality oil and it was delivered when they said it would be delivered.

The best oil available. It’s the only one I use lol n my vehicle.

Been using this signature series for over 3 yrs now and have had a great experience with this product.

I have used this oil in several of my vehicles from low mileage to the high mileage I have now. The engines run exceptionally well. One of the vehicles is going into my 10th year of ownership and runs great. The oil does an outstanding job in residual lubrication after the engine is turned off, and is great lubrication over time. This product is worth the money if you are keeping your vehicle for the long term. I run amsoil in all my engines.

I use this oil and many other Amsoil oils best oils on the planet. I use there oil in my 06 Harley Davidson amazing what it has done with that bike don’t think about it just use it and you will see!

Shipping has always been quick and easy. I change my oil every 10k miles and each time the used oil still looks like it still has plenty of life left to it. Very good oil that I will continue to run in my vehicle. So far, 150k miles on the car and it still drives like it has 15k

best oil ever

We've been using Amsoil for more than 20 years, the best in their field. We've owned a hybrid vehicle since 2000 and have used Amsoil religiously, my second hybrid was serviced (with oil we brought in) and for some odd reason (most likely the technician got distracted), the oil was not replaced. I drove that car for about 500 miles before I knew something was wrong, when the oil light eventually came on, we found there was nothing there. We took it back to the garage, added oil and the vehicle showed absolutely no signs of damage. I'm sure the coating on the cylinders and other components from the Amsoil is what saved the engine.

Works Great in my vehicles,

Great company would highly recommended

so far the best oil i have ever used. i drive about 250 to 300 miles a week. needed something to use that lasts longer then 3000 miles.
