LandShark Posted November 13, 2004 Share Posted November 13, 2004 Not sure if I have a real problem or just no familiar enough with how much soot a turbo engine spits out.:confused: I wash my car every Saturday myself. Each time I notice that the dual exhaust tips are coated with black soot. I was wondering if this is "normal"? I know that I should post a pic but I just cleaned it again so it's not present now. I will take a shot next week. Just wondering if you guys with more years of Subie/turbo experience know if black soot is commonplace. I've not had any sort of performance problem like stalling, lurching, or anything. In fact it seems to run stronger now than ever before. I've got just under 5,000 miles. I did the first oil change at 3,000 miles. Link to comment Share on other sites More sharing options...
Guest *Jedimaster* Posted November 14, 2004 Share Posted November 14, 2004 Yeah, we're running pretty rich- lots of soot over here too- if you go catless, you'll see a lot more of it. And get some cool backfiring too :D Link to comment Share on other sites More sharing options...
Stacie Posted November 14, 2004 Share Posted November 14, 2004 Yeah, what Jedi said. Turbocharged/supercharged vehicles tend to run richer than NA vehicles = black crud on exhaust tips = more pieces parts to scrub while washing. :D Link to comment Share on other sites More sharing options...
Xenonk Posted November 14, 2004 Share Posted November 14, 2004 yea, it's normal.. for safety reasons to keep the engine happily working.. running lean sux.. Keefe Keefe Link to comment Share on other sites More sharing options...
plunk10 Posted November 24, 2004 Share Posted November 24, 2004 perhaps that could also explain the lower gas mileage than n/a cars. Link to comment Share on other sites More sharing options...
