Customer Ratings & Reviews

I’ve used this particular oil in many different vehicles over the years all fords & all have held up great. Including my 2011 F150 5.0 that had 712k on when I sold it. Even my current 2020 Ford Raptor which has 50k trouble free miles. I’d give this oil 10 stars if I could & to me that’s speaks about all amsoil products.

Great effective oil

Been using ams oil for 2 decades never have I had oil sludge or engine issues it’s proven it self time after time

this stuff is great! use it in all my vehicles- wish AMSOIL would include a sticker so I can keep track of my oil changes, but don'y need to buy 100. With AMSOIL, I don't need to change my oil that often!

This is the best motor oil, and worth every penny!

The best there is made right here in Wis.!

I have been using Amsoil products exclusively in all of my motors for over 20 years. I have never had a major part failure due to problems with the oil. Most of my vehicles have had well over 150K miles on them when I sold them and they were operating very well.

I use in everything I own

5w30 signature series makes my jku nice and quiet

This is the oil required for a Mini and nobody around here carry's it. Was able to get the oil timely from you and get the Mini scheduled in its change window at a reasonble price.

Amsoil is definitely a cut above the rest in my opinion. You pay for what you get! This product keeps my vehicle running smoothly and definitely has maintained or improved its performance.

The product is great. Delivery has been slow!

If you are looking for the best oil on the market look no further than Amsoil. I use it in all three of my vehicles. Extended drain intervals and added fuel economy are big qualities.

AMSOIL synthetic oils and products are second to none. The are the highest quality, last a long time, and perform extraordinarily well. Nothing better and well worth the cost. No risk with this product.

I love the products from amsoil, it's very good engine oil, for all your oil look no further than amsoil.

I run this oil in my 2021 Subaru WRX STI. Obviously I have no proof that its working better than any other oil but it gives me a great feeling putting quality American products in my car. Growing up running motorsports we would always use Amsoil and it always performed in that application so I continue to support Amsoil now that all my toys are gone.

I use AMSOIL in everything and recommend to all of my customers.

Everything is fine. I order another one.

Good stuff. All i can say

I went on a quest for the best. Before I tried Amsoil, Pennzoil Ultra Platinum Plus (not the regular Platinum Plus). Amsoil blows that away at a comparable price. If you are in extreme cold, use the 0-W30. For those using 0-W20 in non turbo US models, I highly recommend using the 5-W30 as the rest of the world does. It will only cost you about .1 MPG at 25MPG -- and your motor will last longer. Unless you are in extreme cold weather, then you should use 0-W30. Here's where Mazda felt it was more important to get the extra .1 MPG than making your motor last beyond the warranty.
