Exceptional product.

Still the best in the states you can get and still very affordable when you consider the change interval.

I can't give technical data but when compared to other top brand oils I've used, Amsoil just seems to make my vehicles run better and consume less oil...especially in my BMW!

I have used this 100% synthetic oil since the late 90s and attribute the long life and lack of major maintenance expenses of my vehicles to Amsoil and their product development dept. I used it in a couple of Nissan King cab pickups I drove daily for work as a salesman and my 2004 Dodge Dakota that I bought new had 239K miles on it when I sold it and never used oil, never changed water pump or timing chain. My 2007 Nissan Titan had 210K miles when we totalled it in a one vehicle accident with similar experience on original parts. I used it in my 2010 T&C van and am now using it in my 2019 Dodge Caravan and 2014 Nissan Titan.

Been really warming up to this brand. Seen endless testimony with 1 enduring theme. This is the best there is. Whether it’s pour point, thermal breakdown, viscosity index….doesn’t matter. Every other oil brand has to try to keep up with this one. Just talk to the engine builders, motor enthusiasts, and watch the videos from first hand perspective. The real kicker is, more often than not, Amsoil wins in pricing category too. Especially when you join in their membership plan. Wish I had figured this out years ago. Glad I know now though.

I have 175,453 on my 2013 Ram 1500 5.7L Hemi. Purrs like a kitten. Used Amsoil from day one

The best

In years past, I've had engines go bad even though I did maintenance as required. since switching to AMSOIL, in this case 5-20 I've used just AMSOIL for my engines since 2003 and change oil once a year on each of the vehicles I've had. Every engine was getting the same gas or diesel mileage at the entire time I've had the vehicle and my maintenance repairs have been drastically reduced. I will not switch or change what I'm doing.

All Amsoil oil products are the best you can use in your vehicles. Plane and simple. Harley 04 Car 2000 lawnmower 2020

You guys continue to be excellent when it comes to customer service. Thank you!

Always use this oil and my 14 year old tahoe starts and runs like it did when I purchased it

Excellent product that makes car run smoothly ☺️

Love the oil but was a code for a free hat and instead of sending the hat with the oil it was sent separately and I was charged $28 shipping. Feel this is false advertising

Been using 0-40 synthetic in my 16 Hellcat running it hard no metal flakes in my filter at oil change

Why spend thousands on a car and cheap out on oil. Ams oil products are the best available and a great investment to keep your vehicle running smooth.

Have not used it yet, but it should be good.

Tried it out for first time switched from Mobil 1 and I have better gas mileage smoother running engine all around great and will continue to use

From what I have read and seen on videos the Signature Amsoil is the best on the market . I have been using it in my 2021 Jeep Grand Cherokee Trailhawk with a 5.7 l Hemi since new . I can get free oil changes from Jeep but I supply the Amsoil and my dealer changes the oil and filter . I am trying the 10000 mile oil change now that I am using Amsoil. That comes out at about one year of driving . I want this Jeep to last well over the 200k mark and if all is true I have a feeling that it will . I have about 30 years of experience with race track type vehicles including my last 700 HP C6 Corvette track car . During that time racing oil was a very important subject. So I probably have done more oil specs research then most .

S550 Mustang, 5.0(ish)L, fully built Coyote, PD blower, daily driven, plenty of WOT on weekends, ~600 to ~800 whp (depending on tune up, fuel and pulleys). About 35k on motor with nothing but Signature Synthetic every oil change. Bottom line- motor is as healthy since full break and that gives me the confidence to nail it time and time again knowing I'm protected by Amsoil.

Gotta say I’ve used a fair amount of oil and so far amsoil is definitely my #1. Went a full year with out changing my oil and it burned a full 2 quarts. 2016 Chrysler 200 limited Takes 6 quarts for oil change and filter But definitely, definitely needed to be changed after 6 months. I get it you can go a long time before changing your oil but using a 0w-20 it ended up being thicker and made my car run like garbage, not including the oil loss. I have a new ticking noise that wasn’t there before so regardless double check you levels after a couple months. Amsoil is a great oil just keep an eye on how your vehicle is running. I noticed that I was having a lot less power and drinking a lot more gas than normal. Ended up doing a flush and 2 cycles of oil changes in the same week before it started running back to normal.
