Customer Ratings & Reviews

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.

Excellent oil and service. Still waiting to see what I will get from them since I'm a member.

It seems to work very well in our drag race car! Because our has no dipstick we drain the oil after every outing. I am not a chemist but the oil looks to be as clean and as fresh as it did when it was first installed. I also have noticed our engine seems to run cooler than it did from using the previous oil. Thks

I use this oil in my 17 Camry and could tell a big difference on how to quiet,smooth, and better fuel economy.

I have used this oil in my Zhongshan since new. It is the best oil money can buy period!

Quick and timely delivery for all my orders. Use this oil in my 2015 mustang Gt, never had any issues with the quality or service.

Been using this 0w-30 AMSOIL for about 14 years in 4.0 Ford engine and the results are excellent, with no matter how many miles I drive in a years time. The engine never needs oil added between oil changes and the engine compression test showed 150 p.s.i. and held the pressure in the combustion chamber of the cylinder without losing pressure and held like a new engine for its power and compression.

Truck is running better than ever thanks to Amsoil oil and filter

In the Phoenix heat you need an oil that won't breakdown.

I have been an Amsoil Customer since 1997, I've used their Oils Pretty Much exclusively on Many Different Applications, LEXUS V6, Ford V6, Dodge V8, GMC and Chevrolet V8, and Diesel applications, Garden Equipment, Etc, Etc, Etc. I have had Engines Torn Down and they have been "SPOTLESS"!!!!! As far as MPG, and "O" It Runs So much Smoother, and Quieter, and it Starts so much Easier, and it don't Rattle on Cold Starts...... N O P E, Nothing, Not an INCH Further in Milage or any of that Malarkey, I can Only attest to it Keeping my Engine In TOP Running Condition, and rest assured that wear and tear is absolutely at the VERY Minimum if not, pretty much NON exhistant! I will continue to Use AMSOIL Oil Products Because I have seen the Internal Results. MPG, and All those Other Claims I have no Proof of at all!!!! I have checked MPG form Here to There with No Proof of any Benefit in My Sanrio. If anything to "Complain" about, It would be the Price$$$$$, It is Costly, I'll NEVER Figure that Out???? Anyway, It's a GREAT Product, at an Almost Fair Price. And Amsoil Tech department is TOP Notch, Just Like their OIL is!!!
