Well, I know this.

I need to change my oil, my pre-filter is quite dark looking, and the yellow paint marks on the injector line nuts on the IP are no longer intact.
I will also assume that my injectors are original....how do I tell if they've been worked on?

so, I will change my oil and pre-filters tomorrow and see what happens....This was the first time I have seen this type of smoke from my car.
we have a used oil furnace at work, and my exhaust smelled like the exhaust from that furnace....
