5w flows better than 15w in the winter and gets where it needs to faster but the quality synthetic oil properties protect better than others even in the hot summer months. I won't use anything else. Have a 5.9 and a 6.7 and I use this in both.

Never had an issue

Not sure why when you order an oil change kit for a 6 L diesel you get 15 quarts individually. I know you make a 10 quart jug. Wouldn’t it be easier to send that and then five single quarts or some other grouping of packaging?

I was very skeptical when a fellow driver told me that he uses this brand and how awesome it is, how he doesn’t have to change his oil as regularl as I did and on and on! I took a shot and am extremely impressed with the way my vehicle runs and the fact that I don’t have to change my oil at every 10,000 miles, this oil allows more and oil changes are maybe at 12-15,000! I will no other oil from here on out!

Only oil i run in my 2020 Ford F-250. I do change the oil every 5000. I am very happy with Amsoil products.

Highest quality oil only for my f250

great oil great price quick shipping !!!!!!!!!!!!!!!!

All good

Very good oil flows great and provides great cold start up protection!! I highly recommend this oil for any diesel owner!!

I have been using Amsoil products for several years. I started them after watching a Gale Banks video on rear differential covers. I got to watching more Banks' videos and he would mention AMSOIL lubricants and how they help with the longevity of the motors and other mechanicals on vehicles because of their superior protection. If it is good enough for Gale Banks and his team, it is great for me.

Amsoil speaks for itself . The product is bar none compared to any other oil on the market. I’ve used there oil in several different diesel trucks, absolutely love there products!!! With the cost of diesel trucks and labor. Why not run a superior product in your truck ?! UPS is junk- they just drop $300 worth of product off ware ever they want, even with detailed instructions!!

I love this oil I use it in everything from my lawn mower to my diesel truck to even my gasoline Chevy and my Buick

Works great for my truck. One jug is one oil change. My mechanic highly recommended it.

Product is great but shipping is getting out of control. It used to be 2 days then it’s 4 my last order was over a week. Get a different shipper or figure it out somehow please this is not good for my customers

The truck is still running. I suppose it's doing it's job.

first oil change with AMSOIL ,dealer would do oil change with AMSOIL , tryed to pull could void warrenty ,doing my self now ,put in FUMOTO valve should make next one ease

Been using Amsoil signature series in my 22 duramax since I bought her. She loves it!!!

Been using for awhile and I can stretch out my oil changes to about 25k-30k mi

Great oil, helps keep my Cummins in top running order. 2004.5 with over 215000 miles and still runs like a champ

It makes the engine run quieter,but I think y'all need to make 5qt jugs. The single bottles take to long to open all of them
