I rely on the product being able to go the distance or time frame without worrying about going a little longer because of not having the time to change it . I have total trust in the product. I have had better mileage results with this oil also.

smooth running .

I have used AMSOIL products for 30 plus years. That should say how I like their products

Love the product. No complaints

The knowledge that you've used the best product for the job equals many happy, trouble free miles.

Very pleased with the Amsoil product line. Great performance and this oil is quite honestly the best for my diesel equipment

Good oil

I use Amsoil in all my equipment (several are diesel powered), I'm very happy with their product and I've used it for years.

If you have a powerstroke diesel (any year) you need to run Amsoil oil along with the oil bypass system. My results from Blackstone Labs have been outstanding. We pull a 5th wheel camper and because of the heavy work that the truck does - we change our oil every 7,500 miles / 200 hours.

Noticeable difference in cranking during cold weather. Oil pressure never changes a bit when running this product.

You notice right away after you use this oil in your diesel engine. Sounds quieter and runs smoother. I combine this oil with the amsoil oil bypass filter and Dans from amsoil install kit. I take oil samples and send to amsoil agent. Oil has maintained its initial install standards. Unbelievable.

Use it in my truck. I've always used Amsoil products and have always found them to be high quality.

I use AMSOIL in all my vehicles and they operate great.

Eliminates the typewriter noise that most owners of the Lmm Duramax hear. Been using Amsoil products for years in all of my engines from motorcycles to mowers.

Once a year oil change!

Great product , does more than what it says. All fluids in trucks and dirt , street bike .

I use this product in my 2014 Silverado 2500 duramax diesel. The intervals between oil changes are phenomenal. All amsoil product lines are worth the money including this max duty diesel oil.

Great oil! All of my UTVs, farm equipment, and trucks are diesel. When in the northern sections of the country and extremely cold, there is a noticeable ease with startup vs conventional oils. I'll never go back.

Great product! Been using the diesel oil since my truck was new. Truck now has 155,000 miles and hasn't skipped a beat!

Covers my 6.7 in cold conditions
