every diesel additive (kamil's post about red-line made me think about this..) claims to reduce smoke, but my car does not smoke!

is the light mist behind the car at night what youall call smoke? or should it be thick black smoke like freightliners on the interstate?

im a self-diagnosed worrywort and if its supposed to smoke then dammit, i want it to!

i had a bit of grey smoke that smelled strongly of unburned fuel but a new air filter cleared it up(?)

i was at the burger king getting lunch and the lady commented that my car smelled like a gas heater, there was an auto-parts place next door so i stopped before eating my nummie greaseball on wonderbread.

oh yeah and i lost the wing-nut to the air cleaner, should i worry about that? i dont think i dropped it into an open engine, though...
