Did I miss anything? First time doing an oil change?

Yup thats all you have to do. Also I'm not sure if your truck is like mine or not, I have a 05 Chevy Silverado and to reset the change engine oil message, turn the ignition key to run without starting the engine. Fully press and release the gas pedal 3x's within 5 seconds. The change oil message should flash and that means that it has been reset.
