Customer Ratings & Reviews

I thing your product is the best on the market I knew someone years ago that told me about he used it in his car great oil

I have been an AmsOil customer since pre 2014. A Jeep Dealer Service Adviser recommended I try the 25K mile edition over the 10K I had been using for years While I don't go the full 25K miles I do change between 15 and 20K as I am a full time RV traveler and have all my Jeep service completed back at my purchasing dealer. This extended life gives me one annual oil change a year which works well for my travel schedule. This oil remains clean looking for many miles. I strongly recommend this product.

So far so good. Car runs great.

Can’t always get to doing my oil changes in time so it is nice knowing that my engine is still protected with the best oil possible.

I lead a busy life and maintain 5 vehicles. Using the best oil gives me peace of mind that my engines are still protected even if I am overdue for an oil change before I have time to get to it.

Picked up a 2020Yukon and started off switching over to Amsoil 0W20. I got roped in by all the online reviews and tests. I’ll be the first to admit so far it looks like it’s all true . Immediate divergence in engine noise and much smoother idle. Not sure what the previous owner used but I’m impressed with Amsoil. Did transfer case and I’m getting ready to do both front and rear diff also.

I love AmsOil signature synthetic oil, and is the only oil use it in all of my cars! It keeps my motor running smooth and clean year round!

This oil performs above and beyond.

Love the signature series

Love the products so dar

Best oil out there , been using AmsOil for decades. Have never had a oil related failure. That goes for my oilfield business as well as all seven of my personal vehicle's.

Never fails to protect my engines for at least 5,000 mile intervals. You can even extend the oil filter change to 15,000 miles due to the great detergent capabilities of the Signature Series Oil.

I have been using the Amsoil 10W-30 Signature Series for a couple decades back when it was only available as 0W-30. This product has protected my vehicles excellently. My only concern now is that with the inflation the price is getting a bit steep. As a Preferred Customer three years ago it was costing me $8.81 qt, but now is $11.82. I'm hoping that with the drop in oil prices Amsoil can bring the price back down accordingly. Great product!

Last year when I purchased my 2018 Nissan Rogue I decided to do some research on motor oil. I had been using Valvoline "Full Synthetic" Oil in my vehicles for many years. After doing some research and reading reviews I decided that AMSOIL would be my best choice going forward. I change my oil myself in my vehicles because I like to allow plenty of time for as much of the old oil to drain out before I install the new. With the AMSOIL 0W-20 Full Synthetic Oil I now change my oil every 10,000 miles instead of 5,000 miles like I did in the past using the Valvoline brand. I feel confident doing this because of the better quality of the oil, and can easily justify the higher price I have to pay to purchase the AMSOIL. When I was growing up I always changed oil every 3,000 miles so for me personally it is hard for me to go 15,000 miles or 20,000 miles before changing my oil!

Amsoil seems to be the best oil that I’ve used in any circumstance. Either racing or every day use it’s an awesome product.

Engine looks great and clean inside due to this oil.

What can you say best oil made! not many oils come close to it just use it!

Im using the 10-30 in my Dodge Ram since coming off the show room floor in 2004 .3.7 liter motor 1 million 369 thousand miles later shes still rolling down the road like a champ and no smoke or oil burning . I just bought a new jeep let’s see how it holds up . . The soil is excellent so I’ll be sticking with it from now until eternity excellent motor oil do use in any vehicle Bryan

Very good motor oil. Have been using Amsoil for over 15 years. I use it in my off-road vehicles, my truck, suv and lawn equipment. I change my signature Amsoil at 15,000 kms, well before it’s time, but I prefer more often oil changes. I would give it 5 stars if price was lower. Otherwise, two thumbs up for this great product.

I have bought Amsoil for a number of years now for our Jeep Grand Cherokee Laredo four-wheel-drive. I also use it in my Harley Davidson motorcycle. I would recommend this product.
