I run the 15-40 AMZ/OIL Diesel Signature Series in my Cummins. Oil is still in great shape at 15k with FleetGuard filter. This sample was at 45K on the clock.
Some will say why do a sample every oil change like I have. When I go to sell this these reports will net me a higher price as they can see for a FACT the condition of the engine. The "Universal Average" numbers are averages of 6-7K oil changes. My TBN is strong and the Viscosities are strong along with flash points, these numbers are compared to the oils spec. You can see the previous two samples and how they have improved as the engine breaks in.
So where in this information does it provide which oil provides better mpg like the OP is asking for.
This is more like scope creep and all you proven is you follow the mfg oil change interval and will not command more money at trade in than the next guy
