So this power sevice stuff and MMo I mix and add to the fuel? Its a brand new truck does it need it? Thanks for the info

 

you realy dont need it, however it does increase fuel mileage, the engine runs smoother and a bit quieter, slightly better acceleration, more lubrication for the CP3 injector pump and the injectors.

when it comes to fuel mileage, generaly this stuff pays for itself and then some.
