Does anyone know what the default mileage settings are for the Oil life and Fuel filter in the DIC?

And can you change that setting? If so, how? (I have the steering wheel controls) Owners manual is vague... thanks

I believe the oil is set to 10,000 miles and the fuel filter is 15,000. there is no way to change it without buying some software. I read that you can change those settings with EFI Live, but I am not 100% on that. If you have access to a tech II maybe that could do it too.

Does your truck have the oil life monitoring system? If so, it is not a set mileage. I believe it reads engine revolutions and triggers at an appropriate time. I thought fuel filter was based upon pressure drop but I really don't know on that one.
