How do i turn off the "change engine oil" on dash?
 

so i do my own oil changes and i was wondering how to turn the "change engine oil" off that flashes every time i turn the truck on.

Not sure but try turn key on without starting press accelerator pedal to the floor 3 times turn key off. That was the reset procedure for my 06 gasser. :c:

if you have the steering wheel buttons just press the clear when oil is displayed

The throttle reset also works on the Duramax
