Customer Ratings & Reviews

Been using Amsoil motorcycle oil in my Harley since I bought it new in 2012 and it’s been great, no issues whatsoever. Decided to start using the signature 0W – 20 in my ‘21 Honda Civic 1.5 L turbo for the first time, and so far so good! 4 quart jug is the perfect amount for my vehicle leaving a quarter of a quart for top off if needed. I expect nothing but the best from Amsoil. I recommend it!

I've been using Royal Purple oil for 10 years in my Lexus. I can honestly say I am very impressed with the improvements my engine has since using Amsoil Signature Series. My engine is 50% quieter and I dont burn a quart of oil in 5,000 miles. Thanks.....

I run Amsoil exclusively in my 1986 First Gen 4Runner, the 2200RE engine, the 5 speed transmission, the transfer case and the rear differential. I have over 400K on this engine rebuild, and over 907K total miles, I love it.

A true value over time.

a co worker turned me on to this product after doing some homework. I gave them a shot & been using there products for years. My mechanic was curious too, because they don’t sell in the stores. Have been using ever since.

I use this in a 2019 Toyota Camry. I still do the oil changes at 5,000 miles instead of Toyota's recommended 10,000 due to fuel dilution and mostly short trips.

I just started using this in a Lexus SUV. The owner plans to keep the vehicle for a long time. I wanted to use the best oil I could to help with that.

I’ve been using AMSOIL products for years, and they’ve consistently performed exceptionally well. My 2019 Subaru STI runs on 5W-30, and my Subaru Forester uses the harder-to-find 0W-16—AMSOIL has reliably met both needs. I’ve never experienced any issues, and the level of protection their oils provide is outstanding. In my experience, AMSOIL is one of the best options available.

This weight is much better than the 0-20 that GM recommends for the 2014—2018 6.2liter.. Better gas mileage, better lubrication.

We use this oil in all our 3 Hondas. We would not use anything else

I Heartily Recommend This as THE Best Motor Oil Out There.

Great service. Received my Oil in 2 days. Always dependable with getting my Oil when I need it.

Been using this oil from my trucks first service and will use anything else if everyone uses this oil cars and trucks would last so much longer thank you amsoil

Excellent synthetic oil thanks

I've used Amsoil for years in my Harley. I love it! The Ford dealer charged me $106 for an oil change the last time I took it in......and that will be the last time I take it in. I bought the Amsoil and filter for my truck and changed the oil myself for far less than Ford charged.

great products i use this in everything i own

Over the earlier years castrol was my oil of choice.Since i moved to AZ in 2007 ive used amsoil and decided that was a better option due to the extreme heat our vehicles deal with in Arizona.I NEVER go over 3750 miles on a change and from the few oil sample tests done Amsoil is the proven winner

This is my first time using AMSOIL products I have noticed the engine is running smoother and definitely less engine noise will keep using

I will not go with anything but the best in my engines and that is AMSOIL!

A close friend of mine uses Amsoil products for his and his wife's vehicle's who is always working on every one else's vehicle's but only doing regular maintenance on his and her vehicle's. So he explained that he uses Amsoil products, to better protect their vehicle's. So I did some research and liked what I was finding out about Amsoil. So I've started buying Amsoil products for my vehicle and I feel more confident in the motor being protected. I'm a big fan of the Signature Series from Amsoil.
