Maybe it's just me and my imagination, but my 2020 Chevy 1500 diesel seems quieter with this oil. This truck is already quiet, but this oil makes it sound like I'm driving a gas truck. Your experience may vary. LOL

Highly recommend over other Dexos D gm approved oils for 3.0 duramax. This oil improves your fuel economy by about 3mpg compared to Acdelco oil or the green oil from Mobil 1.
Bottom Line
Yes, I would recommend this to a friend.

Great stuff that out performs OEM oil. My truck has been running great with no issues and my fuel economy has been around 28 mpg but if I grandpa drive it’s 36 mpg. Thanks amsoil and you have a great crew at the Arlington TX warehouse. They are all extremely nice and always quick to put my order together. Someone needs to fly out and take those boys to lunch.
Bottom Line
Yes, I would recommend this to a friend.

It would be nice to increase the milage with this oil, so maybe getting a yearly change would be alot more convenient, i do use the signature oil in all my gas cars, nothing but the best for my cars.
East to order and fast to ship. Great product. Priced well with oil and oil filter but fuel filter is way to expensive. Have to order that somewhere else.
Bottom Line
Yes, I would recommend this to a friend.

I’m using only Amsoil in my 3L diesel GMC. My ONLY gripe is that the specials and premiums they offer seem to fall within days after I’ve placed a stock up order.
Bottom Line
Yes, I would recommend this to a friend.

Purchased for my 3.0 Duramax LZO. First oil change is coming soon and I wanted to put the best in it. Amsoil is the oil I use in any engine I care about.
My truck runs smoother, quieter, and just seems to glide on this oil. Much better than the OEM oil.
Very impressed with Amsoil. I am changing all of my familys vehicles over to Amsoil.
Bottom Line
Yes, I would recommend this to a friend.

Broken bottle

Shipping was way faster than I remember before. Only downside is one of the bottles was split/cracked so the box was saturated and I was out about 1/2 quart of oil. Love the products and have used them for years. Some of the best oil on the market
This is the first time I use this oil on my non-commercial car. My Chevrolet Cruze 2018 (diesel). At the beginning of the autobile, it did not manifest itself in any way, after about two weeks, it was possible to say that my car was diesel only by cold start. Otherwise, the car has become softer and quieter to work. The difference in fuel efficiency is not noticed. High-quality production of packaging bottles, good service and delivery. The price-quality ratio is acceptable! Very satisfied! Made a recommendation to my friends!
