Has keep our Vehicles Running smoothly and efficiently.

I love your company. The best auto products on the market hands down and you always deliver without a glitch. Order is always accurate and the packaging is perfect. Thank you for the great service!!!!!

Been using 0w-20 and 5w-20 in our 2007 mazda 3s since it was brand new. After 107,000 mostly city miles and 10 years Engine still runs like new and have had zero leaks and still doesn't burn a drop of oil between yearly changes. Use Amsoil and create less waste and save money and problems by changing your oil less.

I've been using Amsoil for most of the past two decades. It's the only oil trust to protect my engines and now my firearms. They have never let me down and have earned my loyalty.

Use it in my Lexus with 290k on the clock. Smooth. Nice viscosity. Now use it in all my cars- always will.

I use this product in all three of my Toyotas. It's a great motor oil! My engine seems quieter and smoother, I have not used it long enough yet to tell if my mileage has improved or not. I plan to continue using it from now on.

I use the product for my oil changes, I've used many different oils but no one comes close to this. Loyal customer to this oil

It run a lot smoother than the P**$oil full synthetic I used during my last oil change and is definitely better than the dino juice it had in it when I bought it

Been using this oil for awhile now like all amsoil oils. The best there is

I have been using this oil for years in myc1997 Honda. 235,000 miles later it runs like a gem! Nothing but the best for my cars and truck. Quality lubricant.

Spec. oil that is required for my SRT Jeep.

Let's be honest it's hard to rate in oil...My wife's vehicle calls for this weight. I do use Amsoil in all of my other vehicles so it just made sense. Interestingly when bought the vehicle I changed it over from conventionals oil it came with. Engine, Trans and PS changed. I saw a consistant 1.5 MPG gallon increase(70% highway/25% city).

Used in all my P/U and SUV for past ten Years

I run Amsoil in everything I own, from motorcycles to cars to antique tractors. Why not spend less time under your vehicle a year changing oil? Great oil!

This product lasts just like it says , a great product

I been using Amsoil Signature Series oil more than 10 years and long story short-i LOVE IT!!! If you care about your ride this is oil for you. HIGHLY RECOMMENDED!

I have run Amsoil exclusively in everything I have that runs or moves. I'm convinced it has greatly extended the life of all the vehicles I own including my drag car. 8 seasons without a freshen up, and still going strong. Keeps internals spotless clean too. 40 below or 120 above, it's the best there is.

I purchased a brand new Subaru outback in may of 2016 and will have over 20,000 on it by the time one year comes around my vehicle runs fantastic, did I mention this is an extremely weather environment Anchorage AK. 20 below no problem, purrs like a kitten oil is clean even at 5000 miles love the oil filters you guys make the best there is!

I currently use the 5W20 oil in my 2014 Dodge Caravan, (also previously in my 2006 Dodge Van), and in my 2008 Dodge Dakota truck and very satisfied with this product. I also use 10W30 in my motorhome and have done so for the past 20 years, again with complete satisfaction. As I live on an acreage, I also use 10W30 in my garden/lawn tractor, and have done so for the past 20 years. In my opinion, this is the only oil I would use.

I have driven my Acura TL for over 100k miles using the Signature 5w-20 synthetic. I will use no other!
