Customer Ratings & Reviews

Proud to be a member of the Amsiol Family of users.,extremely pleased with the signature series 0w20 and I always recommend Amsiol products.

You were offering a free item when I placed a big order and Never received it. Haven’t gotten the bill yet to see if my yearly subscription was free with the amount I spent. I’ve got one case of oil that is the wrong weight that I need to send back and get the item I need

Anyone that tells you their vehicle runs or sounds better on one oil vs. another is probably exaggerating. But I have read multiple tests comparing the performance and properties of AMSOIL Signature Series oils vs. other premium synthetic oils and it always scores near the top in many categories. I trust my vehicles with their product because I have confidence in it. It is one of the few FULL synthetic motor oils on the market, and that means something to me. I know it is expensive, but I care about the engines in my vehicles, so it is worth it to me. Thanks AMSOIL.

Been using Amsoil since the late 90's .... contributed to my vehicles' long life.

Best oil I have ever used. Improves fuel mileage and engine life

Very fast shipping and very good price and products

It's the best product I've tried on the market. I've switched exclusively to this brand's products because they consistently exceed expectations, protecting my turbo and engine.

The oil is the very best and is the only product recommended by my 2022 1100 WHP Gt500 builder. I am however disappointed that the free Detailer that was supposed to be sent with my oil was never received… and after reaching out with 2 separate emails I have never heard anything.

Have used in my 2014 truck from the beginning.

OPENED THE CONTAINER AND FOULD OIL IN THE CONTAINER. I THEN POURED THE OIL FROM THE CONTAINER INTO MY TRUCK ENGINE........ Whats to review ? its oil

In my honest opinion this is The Best oil on the market and my vehicles will never taste anything else!

I for one only use Amsoil. This is my first time using this specific one and man I feel the difference. My engine is running even smoother than before on this aggressive tune that I’m running. 100% recommended.

I wouldn’t trust anything, but Amsoil in my Land Rover or my Z06 Corvette

Switching to Amsoil Signature for my wife's 2020 Ford Explorer ST was the beat decision I could have made. Since changing, the engine is noticeable quieter. It seems to run smoother and with the extra miles I get between changes, actually makes this oil as affordable as any lesser brand. The added protection and peice of mind on a very expensive investment makes this my go to choice from now on.

Very Fast shipping rate 5/5 recommend

Change the oil in my 2025 GMC Canyon Denali noticed the difference wright of way . Engine runs quieter more pep.

Ever since using Amsoil my vehicles engines are running smoother and cleaner in the valve system.

Switch from violin to Ames all you'll love it can feel the difference in the gas pedal temperature stays cooler for some reason. I've been using Valvoline. over 30 years I switched and I love this oil

Amsoil is in all my engines - Truck,SUV, lawnmower, Snowblower 👍

Apparently ups damaged the box and returned it. Company did nothing to send me a replacement until I called them. They offered no discount or anything to make it right and now I must wait another 5 days to get the oil. Will not purchase from them again, mainly do to the poor customer service
