Customer Ratings & Reviews

Excellent oil, still looked good after one year in my crankcase. Use this type in my Vette. Please start marketing it in gallon or 5 qt jugs, since my car takes 10 qts.

Every time I order from Amsoil it's an easy process and customer service has always been excellent. The quality of the oil is almost secondary to the service but it is the best you can you get. Will always order from them for my GT350 and can't recommend enough.

I been using this amsoil 50k my truck runs like new 👍 👌

I have used amsoil engine oil for decades. It has always preformed well for me. I like to keep my vehicle for a long time. I put a lot of miles on my cars. Amsoil engine oil has more of the antiwear additives and detergents that going to keep you vehicle’s running longer. Paired with the right filter isn’t a home run in my book. Try it.

Great oil. I use it on our Honda Pilot and Toyota Tacoma. No issues and will continue to use it.

I saw your products through very thurough research online through google and youtube videos. I called a few friends whom race both on drag strip and dirt track. They all agreed if i really cared about my vehicles and making them last then this was the brand to look into. I visited the website and looked at all there was to offer and made a decision to get oil for my fiancees car and my truck aswell. I joined the vip club and happy to see the discounts. I was upset that i couldnt order an Ams filter for her 2016 forester or my 2015 ram 6.4 liter. But that being said both engines seem a little bit smoother and a little bit quieter. Both her and my MPG came up about 5%. I will be ordering everything for our vehicles and our next vehicles from here moving forward.

The best oil money can buy. I highly recommend it.

So far so good , When I get to 500,000 miles and no mechanical problems I'll send in a real review, I have been using Amsoil 20/50 in my lawnmower with great results , I just wish Amsoil had a way to recycle used oil !

Love this oil,got this for my expedition. Swear it feels a bit smoother running this. and gas milage mite have got a hair better. Used to run royal purple. I realy enjoy this now. Confident this will keep me going worry free and with the oil filter from amsoil I can not be as picky on how fast I need to change. Still do around 5k or so takes me 6 months to get that many miles but I go when its convianant,rather then range exiety. I could do 7 if I wanted. I just do december and july changes by habbit. All the test online show this one holds up better then great in lab. If you can spare extra few bucks,go with this,Reason its sold out frequantly. ok because extra range in betwen changes will give ya time to get that backordered shipment. Glide on down those highways,stay comfortable

Have put my trust into Amsoil products

So I am a MASTER AUTO/DIESEL Technician 40 years I own two Camaro's I only use high quality oil in all my Cars including my ZL1. I have other vehicles that are up in there age and miles that my kids use and have only seen Synthetic motor oil. These vehicles are severe duty and do not burn any oil. A Pontiac GTP 135000 PLUS MILES And Chevy Malibu 98000 plus. I am a firm believer in a high quality oil and filter which equals a long life for a engine, Transmission and (Rear Differential or 4x4 front Differential) if equipped. I was taught by my Father and Brother's which oils to stay away from and which to use for engine break in. But for long life Synthetic oils.

We appreciate the quality of Amsoil lubricants. We use it for our '07 Lacrosse, as well as our '01 F350 truck. We've converted all engine, transmission, and even 3rd member fluid (for F350) to Amsoil. Our Buick uses less oil between oil changes, thereby saving time, effort and money! 'Topping off' is much less frequent!

Great oil. I wished I used this years ago

Very fast shipping and easy transaction looking forward to seeing results for myself I am a 35 year technician always heard great things about amsoil

It is the best engine oil I have used so far.

We've been using Amsoil since 2002, it's the best out there

I have used all the major brands. This oil is the only one where I can immediately feel and hear the difference in the engine. Life long user here now. Thank you so much.

I have spent a lot of time researching online through independent 3rd party reviews and data and I have not found a better motor oil and filter than Amsoil (20 microns at 99%). Amsoil is my trusted source for all fluids and oil filters.

I have used this in my 6.4 hemi and have no complaints about it.

This oil is awesome it seems a little much at 1st by price but it's way cheaper in the end and the engine is so much cleaner inside
