I know this Topic has been discussed extensively in the past but was curious how much amount of Black soot you are seeing after a car wash,cleaning etc.

Here's mine after a weeks car wash! thoughts,opinions is greatly appreciated. Z

Virtually none....

Honestly... I gave up cleaning the soot from my tail pipes.... I clean the outside of the tips to keep them sparkling...

Do you think adding that corn in the mix is playing a role? Z

Absolutely

You mean the factory tips aren't black inside?

In all seriousness, I stopped washing the insides of mine also. The factory tune is pig rich and dumps fuel with any poke of the throttle it seems.

One of my best friends has a white Focus ST. He can't keep his back bumper clean because of the high amounts of soot.

I see nothing "eco" about these motors. "Boost" yes, "eco" no.

Real question is, does the extra oxygenation prevent soot from being created during combustion, because as with common rail diesel systems, this is a real problem and an environmental/health hazard.

True! But I think they stepped up there game a bit with the 15my due to there updated PCV System related to Emissions . Z

You have updated valve covers to go along with that system also, correct?

Maybe you're RX catch can system is also helping? Seems that not ingesting oil could help as well?

@ Sholxgt I do have the updated PCV System related to the TSB,but only the front clean side oil Separator is installed.
I think the black soot seems less eminent since having the Meth install. Z

This problem isn't just with Ecoboost, it's seems to be an issue across the board with DI gas applications.

Yes

"No sooting flames with E85
• Ethanol has a single boiling
point of 78.3°C, whereas
gasoline has a range up to
200°C. Thus E85 vaporizes
more readily after impingement
on the piston.
• Ethanol is oxygenated which
facilitates combustion of rich
regions without making soot."

Good point! I see a lot of NA Kia's with blackened rears as well.

I've owned two diesels, so I'm not opposed to soot. Just seem strange on a gas motor. If one of my EFI cars were belching this much black smoke, I would find a better tuner.

GDI = diesel common rail technology. Same issues.

X20000 on not bothering to clean the inside of the tips. I've contemplated simply cleaning the inside of them and then painting them with a high temp flat black so I don't have to see shiny spots in them anymore.
