Been using 15w40 in my 07 duramax for over 150k without any issues. Sometimes it maybe 10-12k between oil changes… no issues. Ordered a 2.5 gal jug… got damaged during shipping. Amsoil sent another one out (so I thought) got the box… 2x 2.5gal jugs for free! Great customer service! ⭐️⭐️⭐️⭐️⭐️
Bottom Line
Yes, I would recommend this to a friend.

Too Good ?
By
Mike ,

October 31, 2021
Months of research has brought me to using this oil in my 2007 Silverado classic 6.6 with an Allison trans. There is nothing better!
While pulling 42ft fifth wheel if the temperature outside is hot 95’ and the incline is long enough for the truck to start heating up 240’ my sensors detect that the oil is low and the truck will go into limp mode until I shut down long enough for the sensors to reset. The truck checks out fine, master mechanics have come to this conclusion.
Bottom Line
Yes, I would recommend this to a friend.
