I have been using this oil in my 2015 3500 Silverado with a Duramax diesel. I started using the oil at 10,000 miles. I now currently have 198,000. It doesn’t use oil and it does not leak oil. I change the oil every 7500 miles. Absolutely love this product.
Bottom Line
Yes, I would recommend this to a friend.

Great Oil

I use this oil in my truck and there is a noticeable difference in hot oil pressure. With other oils the hot oil pressure is about 38 PSI and with AMSOIL 15W-40 the hot oil pressure is about 42 PSI. The cold start valve noise is noticeable quieter with the AMSOIL than with other oils.
Bottom Line
Yes, I would recommend this to a friend.

My 97 power stroke always made a lot of deisol rattling noises, especially when cold..Amsoil made it quiet and ran much better...I pulled a heavy 8 k camper, 2 k miles and I am sure fuel milage was better.. definitely have mo power...in the big picture it's cheaper to use Amsoil.
Bottom Line
Yes, I would recommend this to a friend.
