Customer Ratings & Reviews

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

Best oil on the market for long lasting protection. The prices are getting a bit much, please stop raising them.

The only oil I use on all of my cars

Best oil on the market.

This oil has been the best I’ve ever used so far, been in the car industry for 12 years, first As a mechanic and now as a service manager. The quality of the soil is unmatched, would recommend to anyone

Have been using 5w30 Signature oil and oil filters for my C6 Vette and Ford SHO , plus my 2020 King Ranch 3.5 twin turbos. Best oil I have found! Never have I had any issues

I absolutely love this oil. It provides superior protection and outlasts the previous synthetic oil I used. Virtually no metal particles visible when do an oil change in my car. Like the old saying goes you get what you pay for! Well worth the money.

Amsoil products never disappoint
