Customer Ratings & Reviews

I’ve used this oil for two years and recently had it tested after 11,000 miles. Testing showed this oil to be in great condition, no metal and chemically still strong.

After intense research on all oils only amsoil finished 1st. Most synthetic motor oil only are 10 to 20% synthetic Amsoil is almost all synthetic over 80 % It stands alone as the best motor oil for your vehicle by far

Great oil. Using it on two of my vehicles. Gas mileage improved and since switching a few years ago, I find that my oil levels stay consistent with less evaporation or burnoff versus Mobile or Penzoil Full Synthetic oils.

I’ve been using your oil and other products for over ten years,now two my sos do as well. Great company.

I have been using Amsoil in all of my vehicles for years. 2007 Toyota Tacoma with 335,000 miles runs like it is new, 2010 BMW 528 with 145,000 runs like a top and last my 2005 Ford F250 Diesel with 265,000 runs great. Simply put all 3 of my vehicles run great, have never broke down and it is because of regular service and Amsoil. I also use it in all my lawn tools and lawn mower. Simple-it’s the best !!

Absolutely the best oil I have ever used. It is everything it was advertised to be and more! Nothing on the market even comes close to the quality! Job well done!

Great product. There is a reason why people pay as little more and wait for the shipping (which is a couple days at the worst). I will continue to use this in every engine I have

Use this one both of my lexus is300's. My daily had over 300k and my fun one had 150k.

I purchased my AMSOIL products by word of mouth testimonial from someone who I trust concerning topics such as automotive care, and they were right! My 2006 Nissan Frontier 4.0L is experiencing a rebirth in fuel economy! It's always been a great little truck, but since changing over to your product I believe that my engine is not working as hard as it was, and it has 207,000+ miles on it! Thanks Amsoil, I'm telling family and friends about it!

Very happy with Amsoil products.

I run this in my wife’s Kia that has close to 200,000 miles on it now. The engine doesn’t burn any or or make a sound. This oil has been great!

Changed oil on my 2014 Subaru forester, has 86,000 miles. Running great.

Switched to Amsoil for the price and reviews, change oil at 7k and still looks clean

Unfortunately I could not use this product, I bought a new truck before the oil change was due and now it's just sitting here

Ive noticed a little better oil pressure on my 18 Silverado 5.3 ,it calls for 0w20 oil and I personally think the 5w30 higher mileage works better for the hot Illinois summer's that we have and I've cut my oil filter apart and there always clean .

Best oil for your car engine

Been using the high mileage oil in my F-150 since the odometer passed 100,000 miles, engine runs smooth and very quiet, extremely happy with this motor oil.

Great product! Very fast delivery 🚚

Best wear protection money can buy I have 296k miles on my 2012 Honda Accord with continuous use in the engine and transmission this car will hit 500K miles without breaking a sweat

Thank you for such great service. My original order was damaged in transit. I received notification from FedEx. I called Amsoil customer service and they immediately sent out a new order and I received it quickly. Thank you so much for quick service. Again, it was great to work with such great people who worked quickly to resolve my issue!
