Most debris that you would possibly get is from dirty tanks at fuel stations or filling up while the station is also getting re-filled. The fuel truck causes the tanks to swirl up all the crap in the tanks, so avoid filling during those times.

Forget all that stealership crap and run a tank with Seafoam to help break up any carbon that might have built up. Then changes the fuel filter, oil, and oil filter and call it good.

Carbon build-up on the valves, guy.

I'm a tech an Audi dealership. We do these at my dealership. You don't have to do it, but I do recommend them if your engine has direct injection. Since the fuel injectors spray directly to the cylinder and no longer spray behind the valves. Which can develop carbon build up due to the crankcase ventilation system. I personally do the service to my cars once a year just because its easy for me. Just gas up with good quality fuel and add some fuel system cleaner here and there. We connect a tool directly to the fuel rail and run the concentrated liquid through the fuel injectors. Then spray some liquid through the throttle body while the engine is running. A lot of dealerships offer that service. So, is really up to you.
