Customer Ratings & Reviews

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!!!

Best oil I have ever used

Excellent product Fast shipping

This is hands down the best oil for your EVO X

I used this to replace the motorcraft 5-50 on my supercharged coyote engine

Who could complain about increased performance, better mileage and 25,000 mile oil changes?

Will buy again for my camaro ss

My Jeep just surpasses 225,000 miles and the engine pulls like new! Recent borescope to check for a possible leaking head gasket showed little to no wear.

I have a 2014 F150. Since Ive been using Amsoil, my truck has been getting around 20 to 21 mpg on highway. Before I was getting around 18 to 19 mph average on highway.

I just rebuilt the motor on my 2003 WRX and have used only this oil after breaking it in. This is all I'll use on my car moving forward. Cold startups are a breeze and the car feels much happier.

Been running this oil now for about 2 years, I track my car once a month and oil temperatures get a little warm. I recently had my used oil analysis done by a third party and after three track days and Camarofest the oil was ready for more. It cost a little more, but for me it is worth the piece of mind on the track.

First time using it in my truck but so far so good
