I don't ever say my oil brand used, change method, time interval or mileage is best. I simply show the results of what i do and others can glean what they may from it.
BTW, I don't "CHEW" so I have lots of money to do my oil analysis. :B
Here is every oil change since new on my 2015 6.7 Cummins. I use AMZ/OIL 15-40 Signature Series and FleetGuard Stratapore filter.
Universal Averages are based on around 6k changes. Note he said I could go longer than 15k if I so choose after warranty!
