Customer Ratings & Reviews

My previous truck I used the engine flush & rebilt the top end of motor. I was using 5/30 excellent oil. Now I live & die by these products, would recommend to anyone.

Was using the OEM switched to the signature 5w30 and noticed a difference wright away ran better gas mileage and ran cooler would highly recommend this oil my choice from now on

Works good

Fast shipping, easy to pour, I am nowhere near the 25k mark only about 2500 miles in, so time will tell, not sure if I will go the whole 25k as its against my religion, but I am sure I will get close...

Great oil I use it in most my vehicles and never had an issue with one running it.

First time trying this product

Quick shipping, solid American made product. I've been a customer for years. Ram 4x4 hemi.

Order was here quick and correct

I've been using Amsoil in all my vehicles, boats and off road toys for many years. I truly believe it is the best oil made.

above all expectations with this 0/40 for my Z06 Corvette!

Awesome product

I was using Pennzoil Ultra Platinum 0W-20 Full Synthetic for my Honda Pilot 2016 exl with 261K km in it. Obvious crackcase noise & lifter noise. Fuel consumption of 12.9 liters per 100km. Now with using Amsoil Signature Series 0W-20 Full Synthetic...noise in the crankcase & lifters are a lot less. My fuel consumption is now 11.8 liters per 100km. The engine run smoother than it was. I wish i've used Amsoil ever since. Now, i use it in every vehicle i own. I highly recommend this product.

I run the Signature series Amsoil in all my family vehicles. I change my daughters vehicles every year and the Ecoboost every 7,000 miles. I consistently see a 10% increase in interstate fuel mileage when converting over to Amsoil. Protect your investment with Amsoil products, you will be glad you did. A small cost to pay for peace of mind and protection. My Tacoma and my F150 all have over 250,000 miles and neither use more than 1/2 qt oil in 7,000 miles. The daughters cars typically log around 12,000 to 16,000 miles per year and most of their cars have over 200,000 miles. Switching to Amsoil typically results in less oil consumption due to the thermal stability alone. Great product.

Reliable product. Quality and have been pleased with impact on a variety of different vehicles.

Thanks

This oil gives me the confidence others don't

Love Amsoil products.shorted me 2 qts of oil. They took care of it though.Had to find another dealer to finish oil change.

Peace of mind using Amsoil products.

I’ve been using this oil on a supercharged v8 for 5 years. Motor still sounds brand new.

This is the hands down the best oil for all my cars. Never had any kind of oil leak or ever burned oil using amsoil. change my cars at 7500 miles or one year. Simply the best and guaranteed to be 100% synthetic.
