I "think" my smoke changed from CHARCOAL BLACK to smokey gray.
Could this mean anything?
I just remember leaving puffs of B L A C K smoke, and lately when I get on it it seems more transparent and gray. Dare I say it, but kind of "burning oil like".. Maybe it's just the sun lighting it up but I really think the smoke is more gray.
Truck is running strong/reliable as ever, and no engine oil seems to be lost..
Idea's?

Don,
Do you guys get "winterized" diesel in Santa Barbara? If so, that could change the color. Winterized diesel is usually a blend of #2 diesel and #1 diesel (kerosine). Kerosine burns better (more complete burn hence less smoke) than #2 but is a lot more expensive per gallon.

My exhaust changed from black to a light greyish color when I started running Bio-diesel, around a B20. But, that is not an answer unless you're running Bio, sorry.

Winterized hmmmmmm... Maybe I'll ask...
It does seem season dependant, as at Glamis a few months back it was BLACK, and now more grey. They truck does seem to have more power now too with lower EGTS???

It sounds like better atomization or less of an excess of fuel.
Thinner viscosity fuel or more dense (colder) air could lead to those two improvements. Maybe lighter pressure on the loud pedal.

Smoke?
Don,I live south of you here in San Diego. Years ago I went out to Fred Swanson's place near Phoenix for a tranny upgrade. He explained to me that our trucks smoke more in a desert climate(Glamis) than a higher humidity climate(Santa Barbara). It seemed to be accurate as my truck smoked far less here than in Phoenix. Anybody else? Until Marco released the new programs,my truck belched one color:BLACK and that was here in S.D.

Hey Don, you didn't by chance get a biodiesel blend without knowing it? I ran B20 for a few tanks, and smoke was noticeable lighter in color.
Also, the new ULSD 2007 fuel seems to give a greyer haze than the old low sulfer diesel.

It's ~32 out today, and I drove my truck for the first time a while. I noticed FAR less smoke than I'm used to. The little bit of smoke that was there was definitely more of a dark grey as you mentioned. I'm in Texas, so I suspect we don't have winterized fuel and this can just be attributed to the low temp allowing more fuel to be burnt. It was too bad because a friend who was riding with me wanted to see the smoke show!
