Customer Ratings & Reviews

Best oil on the market,motor runs super quiet especially with 115k mi. on the clock,a little pricey even with the membership discount but well worth it.

Running in a `16 Suburban L83. Runs great! Smooth and quiet. I don't know of a better oil for this application!

I have been using this oil for more than ten years in both my cars. I only change it once a year. It costs me less to use this high quality oil than it would to change my oil every 3000 miles. My Jeep has 140,000 miles on it and still runs like new.

As I have needed inventory, I have been switching all of my vehicles and engines over to AMSOIL. This is the first time I have used the 5W-20. It does not disappoint, never thought it. On top of the oil being great. the service that you get from this company is outstanding. I ordered this as a last minute order as I thought I had my other oil in my inventory. I went to service this vehicle and I had no oil. I ordered the AMSOIL and the order said it would take longer than normal and to expect it in a week to ten days. I actually received two days after my order was placed. Some of the praise goes to the shipping company, but most of it goes out AMSOIL for shipping the same day as the order is placed.

There are a lot of good motor oil products, but I have to say based on the performance I'm getting out of my vehicle Amsoil has got to be at the top of the list !!

I have used Amsoil for many years and found the products to be exceptional. No issues to date.

Just started using amsoil again after many years! Finally bought a car that it was worth running in. Great products and exceptional shipping time.

I haver 5 vehicles none of them get over 12000 miles in a year so I change all in December I feel like I am using the best lubrication protection on the market so even if I went over 12000 mile no problem

I purchased my 2011 Chrysler 300 used with 17000 miles and immediately switched to Amsoil and today she's at 105000 miles and no engine mechanical issues whatsoever. I also change my oil filter cartridge every month to insure clean oil.

I have been an Amsoil user for decades and will use no other filters or lubricants in my vehicles.

I got tired of formulas changing and price swings and availability issues with other brands....I have switched for good to Amsoil and am pleased with the performance and protection

I have used Amsoil in all my vehicles since 2005. 0w20 is great

you need a different system to find the oil filters, i spent one half hour trying to find the oil filter, i finally had to call and she told me where to find it. thats not right

I use Amsoil in all my vehicles, family has three Subaru suvs and one GMC Sierra Duramax Diesel truck. I do two oil changes in a calendar year on each vehicle with no issues and Performance is excellent . Highly recommend Amsoil brand. I have been using it for over twenty years.

Amazing product and officially hooked. High Quality synthetic oil with exceptional longevity. Only oil all my machines will run on!!!

Have used this oil in multiple vehicles no issues and run on extended drain intervals of 7,500 mile oil changes using purolator premium filters. Amsoil ships the orders quickly and always correct No Complaints.

I'm on my second oil chx with this prouduct & I can't describe fully how it improved my engine. It runs so quiet I have to make sure its running by rolling down my window. I chx Oil & filter @ 8,500 miles and probablly could have gone more miles. It Improved engine response, about 2 more mpg. and it starts up very fast & quiet. It was such an improvement over what was being used I will never go back. This is the best engine Oil I've every used, an AMAZING improvment over conventional engine oils.

Great quality oil,

Amsoil has kept my Shelby GT engine in like new condition. I use it in my Lexus SC 430 too with same results.

Just put Amsoil into my new Jeep Grand Cherokee L at its 1st oil change. Hopefully Amsoil does for this engine what it's been doing for my Ford Flex since it was new, which now has 423,000 miles on it and is still going strong with my daughter driving it.
