Customer Ratings & Reviews

Been using Amsoil, exclusively, for decades, in many vehicles. Never one oil related issue. Currently have a 2020 Ram 2500 6.4 gas engine. Those engines are known for cam/lifter issues. Most "tick", some experience cam and/or lifter failure. My truck has 21k miles on it so far. I change oil & filter every 7k miles. Engine is not showing any sign of typical failure. No tick whatsoever. I have been an Amsoil dealer for 20+ years, and mostly only for my own needs. Amsoil is the best IMO. Also, check out PROJECT FARM on YouTube if you need further proof.

Definitely worth using if you wish to extend the life of your engine. I've used other motor oils in my 2016 Power Wagon, but I won't use them any longer regardless of what the shop recommends. My truck has a little over 130,000 thousand miles and she still sounds and runs just like she did when she was new.

Just open the box and examine the filter. You will know why you’ll never waste money on anyone else’s filter again. Durable seal and solid construction. It stands out.

I'll put it like this. When I buy my dream car I will swap all fluids to amsoil from day one. YOU WILL NOT BE DISAPPOINTED.

Have utilized Amsoil in my vehicles for decades. Very happy with the results.

I have used OW-20 Signature Series oil in my truck ever since I purchased my Truck back in 2014. That oil has never failed me. Every time I change at 15k intervals, it continues to look like new still. I wish someone turned me onto Amsoil years ago.

Wonderful

Best oil out there period, viscosity holds up the best of all the other synthetics

Saving money is making money at only needing one oil change per year. Plus the added performance is noted especially in MPG.

Good product, drastically overpriced.

I have friends who have used nothing but AMSOIL products in their vehicles and have gotten hundreds of thousands of miles out of them. This is the first vehicle I've owned where I have started with the oil and air filters from brand new. When I get more miles on my truck, I plan to replace all of the fluids with AMSOIL products - transfer case, transmission, etc. It's a little pricey, but it's actually saving me money when I only have to change the oil at 25,000 miles. When I place my order, it's been pretty incredible that a box arrives at my door the very next day!

The best product from the best people. What else is there to say?

As soon as I paid off my Lexus 2012 350RX,I stopped taking my car to the dealer for maintenance, but also I wanted to make sure that I'm getting the best protection for this engine, I've been using Amsoil in a 1998 Mitsubishi Montero sport and had no problems at all with internal parts in that engine, so it was a no breading to keep on using Amsoil in this Lexus, great product, I believe in good maintenance better that repairs, and this product hasn't let me down.

Been using this in my 2015 Kia and running it for 25,000 miles between changes. Oil doesn’t look bad at change and that assures me it’s doing the job.

Awesome oil! Works well in my Honda Pilot. Saves me money and low miles = one change a year. If you gonna do it…do it right!

Great oil, I trust it

Only oil that I have found that helps with gas mileage.

This is the best oil out there!!! My truck runs smoother and much quieter also!!

Perfect OEM replacement

Switched to this in my 14 Outback which used 0w20 and burned a quart every 2000 miles since new. I was running 15w40 but mpg suffered and with the rising price of fuel, went with a zero weight oil. No more burning and better mpg
