I dropped the factory-fill out of my '23 Miata at 500 miles and replaced with Amsoil Signature Series 0W-20. Still running an OEM oil filter (1WPE-14-302). I'm 700 miles into the party since said oil change and all is well. My previous car was a 2018 GT350 that I dropped factory-fill on at 800 miles in favor of Signature Series and it was at 24.5k trouble-free miles when I sold it. Good stuff.

The best motor oil I have ever used.

If u could tell folks how many quarts are in ur jugs would be very helpful. Most would think it’s 5qts and not 3qts

I've used AMSOIL products for over 30 years, it is the best in the industry!

Really like this stuff! Great for smaller 4 cylinder engines and allows a longer oil change intervals.

Have not changed oil yet, but expect it to be great in my truck.

I believe Amsoil is the best oil on the market. I use it in all my vehicles and equipment and encourage all my friends to do so also.

It had been 7 years since I had first tried amsoil. The product I had been using changed their formula so I switched back to Amsoil

Excellent engine oil for my 2004 honda crv. Amsoil is the best.

I’ve been using the signature series for many years and it has never let me down. Feels great knowing I use the best oil available on all my vehicles and equipment.

I just finished my first 0w20 Signature Series oil change after 23k miles. At first I was having a shop replace oil filter (Napa Gold 7002) around 5-6k miles which I had done 3 times. Then when talking with Amsoil Technical Support, was advised it was fine to go 12k miles with the Napa Gold 7002 filter. Just under 12k and before a long road trip, I went to my original mechanic to change oil and filter. This shop is listed on Amsoil website. This time, the oil was really black and dirty. Shop advised me to not ever go over 5-6k miles on an oil filter no matter what Amsoil says. Furthermore, they advised me to just use Mobil1 since it's much cheaper. OMG. I'm not sure if using Napa Gold 7002 filter for almost 12k miles like Amsoil Technical support recommends was safe for my engine? I guess time will tell. I believe in Amsoil products, but perhaps 25k miles driven (90% highway driving) is a bit much? Also going 12k miles with a regular high quality filter might not be good. My long time go-to mechanic I run everything by died suddenly last year, so I no longer have that trusted resource to go to. Think I'm going back to replacing filter at 5-6k miles along with an extra quart of oil and not exceeding 20k miles.

Love all y'all's products Amsoil customer for life!!

Très satisfait

I’ve been using Amsoil products for over 25 years and they have always exceeded my expectations!!!

So far I am very happy with Amsoil products. I use them is all my vehicles. So far so good only time will tell the truth as far as wear and tear.

The best oil I have ever used

Awesome product that will exceed your expectations!

Big difference on engine noise from factory recommended oil to Amsoil. The engine is very quiet and the oil looks cleaner between oil changes.

Great product, I should have been using it sooner.
