Customer Ratings & Reviews

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

I have used amsoil for over 20 years. I believe it’s a must have to reduce the wear on your vehicles engine. Especially now that the cost of new and used cars have increased exponentially. Amsoil cost isn’t that much more then the competition. It’s insurance to keep you vehicle operating longer.

Great oil, watched multiple YouTube videos comparing numerous brands of oil and Amsoil came out on top every time. Will be my go to oil from here on out.

works well for.my truck

I've been using Amsoil for over 20 years. I've had experiences with other bikes overheating when we're riding on a big V-Twin and mine running perfect, to my daughter running all the antifreeze out of the car and driving for almost 20 miles never overheated. I just put it in my new tundra which I tow with, and which I take off road. I would never use any other oil in my truck or bike. It is the best hands down. I don't care what anybody says I've seen it I know it!!!

Amsoil is the only oil I use after I switched from valvoline extended protection specifically this and the xl boosted my engine runs so much smoother and quieter even after going more than 5,000 miles. The competition if you can call them “competitors” after 5,000 miles starts to thicken there is no competing with amsoil!

Wouldn't use anything else. 2018 mustang gt with whipple supercharger. Nothing but Amsoil. Simply the BEST!

I only use Amsoil products in my Corvette and Dodge Ram diesel. From oil, filters, brake, and differential fluids. I'll use Amsoil in my transmission when I replace that fluid.
