Hi all, I'm a newb to diesels, so forgive my ignorance and newb-tastic questions...
I've got a '96 Golf TD, and I've been running fuel from Canadian Tire, until today. I had to fill up at a different station (busy PetroCanada), and all today I've noticed I'm blowing black smoke when I accelerate in 3rd gear... normally I only see the smoke when I put my foot into it in 4th or 5th.
Of course it was warmer today than usual, so am I seeing a temperature effect, or will different quality diesel cause this to happen?
