Customer Ratings & Reviews

I have been using Amsoil for a long time now and it always performs great in any application that I have used it in. With the Preferred Member discount it’s priced right along with the competitors. It’s the only oil that I use and I love it!

I switched from the “top brand” recommended by my friends to Aimsoil. I have never been happier of the switch, especially having a turbo charged car. Aimsoil can handle the load of the turbo with no problems. I was running low on oil by the time my next oil change came with the other guys, not with Aimsoil. I still have plenty of oil by the time the next change comes along. Won’t be going back to the other guys.

I need more mudslinger. When is it coming back. I got people wanting more. I need a whole case.

The oil is one of the highest quality oils I have used I put it in every car I own. The preferred customer saves me a lot of money as well

This was my first time using amsoil and so far it has been amazing. I was using Mobil 1 and this was the greatest switch all I have to if you are thinking of switching don’t hesitate!!

Great product. Definitely feel and hear the difference in the engine & performance.

I use nothing but Amsoil in my vehicles! 🇺🇸

I use Amsoil in all of my vehicles and there has always been an improvement in fuel economy. All of there products quality are second to none.

I have been running OE 5w30 in all of my daily driven vehicles that require it for almost two years now. So far, it has been an OUTSTANDING oil! My daily driver is a 2018 WRX, which I run 5,000-mile OCIs. Since owning the car, I have never had to add oil in between oil changes, which is common on turbocharged engines. If you're on the fence about the switch to Amsoil, do it!

Used this oil in my new to me used Cherokee. Changed oil about a week after I got the vehicle since the dealership did not change the oil during their prep for sale. The oil seems to make the vehicle run smoother. We’ll see how in holds up over the course of the next 10k miles.

One of the best oil that I use in all my vehicles and bike I can tell a big difference in running this oil in all my vehicles

I use this oil first when I switch to Amsoil Signature or other 100 percent synthetic oil. I run it for about half to 75% of the oil change interval, and also add about 4 oz of Marvel Oil. This cleans out the engine well and preps it for the premium synthetic.

So far so good, mpg already improved, car feels smoother and runs better. I'll stick with this brand for a while, actually thinking of going into business with them.

Great product at an affordable price

I prefer using Amsoil to protect my engine in our high heat climate. I prefer the convenience of a longer drain interval allowing me more leewya in when I'm not able to change every 5k miles.

Been using this oil in my 19 Expetition and 09 Civic for the last two years. Engine runs smoother and has 8-10k mile service internals with no oil consumption issues.

I have been using Amsoil since 2008 in all my vehicles and motorcycle. I trust the product and want to protect my investments with the best.

Good oil Take care my engine

this stuff is great, i use it in my mowers, trust it and its protection

I use Amsoil in all of my vehicles. It is a little more money then the conventional oil you by at you local part store but is well worth every penny plus the warranty is worth it alone
