Hello,

I have a Maxima SR and it has about 1,000 miles on it. Already, I notice a large amount of black soot on the tailpipes. I have been driving carefully without exceeding 3K rpm and I don't notice this issue on my other higher mileage Nissans. Would this be normal on a new car? I have used premium fuel and it runs great. Hmm..

 

Thats normal VQ Engines run on the rich side, that means lil more fuel then normal.

 

Also, once the engine is broken in well, say between 5 and 10k miles the soot should become less. New engines tend to use a little more oil until the rings seat in the cylinder bores. You probably won't notice oil usage on the dipstick but the tail pipes, especially chromed tips, are telltale in a new break in.
