Nope, bad idea. Fouls plugs but will also carbon up valves seats and guides, makes engine less efficient so it has to work harder, runs hotter, wears out quicker. Yes, oil is a good lubricant but long term carbon build up is not. Loose carbon circulating around in engine will plug small oil channels and bearing surfaces and lessen oil flow through the engine where it needs to get to causing more friction and shorter life of engine. Don't do this.
I would probably take (Bud Lite)'s opinion serioiusly... Remember Chevy is the longest lasting and best resale truck in the world and that is with regular "recommended" maintanance.. Bob
