I just got back from a 1000 mi trip with the truck,I noticed my tailpipe is coated with black soot. anybody else notice this and is there a known cause and cure, thanks

Is the truck an EB? They soot up pretty badly on the exhaust tips. It's one of the side-effects of a direct-injection engine if I recall. My EB makes much more soot than my 5.0.

its just the carbon build up from the inside of your engine gettin out the exhaust

yes this is an ecoboost. it just seems to me black carbon soot is a byproduct of overfueling.I guess not though, thanks for the replies

Just spool it up frequently! Helps keep things cleaned out :-)

I wish that were true. Haha. Mine is flogged quite a bit and my bumper is always glazed with black.

Strange. I've never noticed it on my bumper. Tailpipe gets blackened but not terrible.
Maybe fuel quality?

It is normal. Every EcoBoost I have seen has black soot all over the tailpipe. My wife's Explorer Sport with the EcoBoost has these nice fancy polished tips, but you can't ever see them because they are always covered in soot. I guess it is the price we pay for having a great engine.

EcoBoost, 5.0L, 3.7L, 6.2L macht nichts.

WAD - WorkingAsDesigned. And has been the norm since modern-day electronic fuel injection.

At cold start-up the ECM automagically puts the fuel system in rich mode with a higher-than-normal idle RPM. The resulting soot will get blown-out and deposited on the exhaust tip or end of the tailpipe along with the normal, cold-startup backwash water/moisture.

Mine used to let off a nice puff when I stomped it from a light. We won't discuss what my megacab does haha.
