I have used other oils but Amsoil is the best!

My 2012 Corvette Convertible has over 115,000 miles and still runs like new! With other brands of motor oil, I was starting to hear those little noises that an older engine makes over time, and I figured that was just the normal cycle of engine life? I started to use this product the last two oil changes, and those little noises are gone! It’s like I poured in a new engine in the process. I wouldn’t use any other product on my Corvette, and I’m looking for many more miles to come.

I've used this product before in my sports car years ago but decided to use it again in our fairly new aging cars. I instantly noticed an increase in horsepower and performance and reminded me of why I used to buy this oil years ago.

I run a tricked out Jeep off-road. I drive it hard and often. Trust no other than Amsoil!

Try one time and your vehicle will tell you, what it was missing. You will feel the smoothness of the engine. This is a great product.

Oil works great.

Bought an ‘08 Sierra 1500 brand new, always ran full syn valvoline. The AFM started acting up and the oil pressure dropped around 170K. Switched to mobil1 with 1 quart amsoil and within 1k started washing that old garbage out! Had to change filter! After 3K, went full Amsoil change, and again, had to change filter at 2k, another 2k, and another 5k. Another full amsoil change and no problem since! Totally washed the internals out! Super cleaner additives for sure!! AFM and oil pressure problems gone at 193K and counting

I have used Amsoil products for the last 21 years. The oil is great and all lab test results prove that. Changing my oil once a year also saves me a lot of money.I average about 10,000 miles a year and when changing the oil it still looks and feels great.

So far this oil has been fantastic!!! Engine runs noticeably smoother and a noticeable increase in fuel economy.

I have a 2000 Silverado 5.3 started using amsoil instead of valvoline & it’s really quite running engine after using this oil. Use 0w20 in my other cars and have no complaints. Very good oil!!

As always my first oil change will always be Amsoil

No problem

I am new to Amsoil and the reason why I switched from Mobil 1 to Amsoil because I came upon videos on YouTube and Amsoil consistently came up as the best synthetic oil for cars and trucks. I decided to give it a try on my 2017 Honda Civic that had only 11,000 miles on it at the time and I noticed how I got better gas mileage and that my engine runs quieter. I wish I would have known about Amsoil years ago but I never knew about it because you cannot find it in stores.

Switched to Amsoil years ago and haven't looked back. My cars run smoother and cooler with Amsoil. My wife's 4Runner has over 365k miles and runs perfectly. Still outruns newer cars with ease.

I only change my oil once a year in my 2011 corvette due to riding a motorcycle most of the time (which I also use Amsoil in my motorcycles as well). Amsoil's performance and protection is well worth the time and money. I no longer go to oil places to have my oil changed; I invested in reusable oil filters that I clean my self and use Amsoil. In the 10 years that I have been engaging in the process, I have not had one engine issue with my motorcycles (which I abuse) or my corvette. I highly recommend Amsoil products and use them frequently.
