I'm happy with this!

Blackstone report on my 15 RAM Dually towing 33-35K, about 1/2 of the miles were towing.

AMZ/OIL 15-40 100 percent synthetic with FleetGuard Stratapore filter. No oil was used with this 15K report with 45K on the clock. Other two samples are shown.

    I am impressed with the viscosity numbers as they are on the top end of "Should Be" after 15K. I am sure my TBN number last change was higher than this time because I added 1 qt last change and added nothing this time.

    Pretty good oil analysis. About the same numbers as my last analysis numbers using Delo 15W40 conventional oil. I am not sure why some people are so afraid to go the full 15k or past the 6 month mark that the manual states with these truck. Every oil analysis I have done(they are free for me at work) have come out with great numbers.
