Re:Brown smoke
It could be the fuel....so I added some RED LINE 85 PLUS to see if it helps...I took a fuel sample and everything looked clean...guess I wait and see if it clears up

Re:Brown smoke
Nitrogen oxides are reddish-brown in color, a by-product of diesel combustion. You dont noramlly see them in this color though. <br>Advanced timing and the right conditions could cause this to happen. The right conditions could be the fuel quality, blending, cetane number,etc.<br><br>Run another tank of fuel and "see" what happens <br><br>Don~

Re:Brown smoke
Looks like the Red line 85 Plus helped...I am back to normal looking black smoke...I stopped by the truck stop that I fueled at and asked if they had any troubles with the fuel and talked to the manager....he told me they just had a dirty tank cleaned and treated and that I must have gotten fuel from that tank...he said the treatment additive would not hurt my engine and if I had any problems to let him know he gave me a free gal of Howes Diesel Treat for my troubles ;D

Re:Brown smoke
If they kicked up alot of crud you might want to look into changing your fuel filter a little sooner than normal. May only need to pull it to look at the color on the top of the filter but I would err on the side of caution.
