I have 11k miles on my truck. I have had my truck to the shop a few times for multiple issues. now I seen the other night that my bumper is black from the exhaust. My truck is white so it looks like hell. I tried last night to get it off and I got some but I could not get the rest off.

I am about ready to shove this thing up somebody's ****. I will try to post a pic.

would my truck running rich or plugs have something to do with it?

Put gas in..... Diesel emissions!!!! Don't go rolling coal on unsuspecting citizens now!

Any mods to the truck or is it stone stock?

Sounds like its running rich. I hear most ecoboosts do this at the beginning. Its supposed to go away, anytime soon based on your mileage. Mine did the same, I have silver and there would be soot on bumper sometimes. I never narrowed down when it was worse, it just went away.

i have heard of soot on the tailpipe but never bad enough to get on bumper. but we just had a fusion loaner that had alot of soot on its white bumper

here is a pic... it doenst show real good but there is a lot of baked on greasy soot on there. this pic was taken today. I spit polished the truck yesterday and worked for over a half hour on this spot alone.

the specs are 'new soot' from driving about 15 miles to work this morning.

truck is bone stock.

here is a recent pic. it was almost 75 degrees the morning I took this picture. about 3 minutes after I started it. this is more of a white smoke color but a lot of it.

Bad gas and running rich. the computer is trying to adjust for it
use some type of gas cleaner
see if that helps maybe
octane boost additive

Probably the ethanol in the gas. Direct injection motors usually have a little soot
