i already did the convert. scene with a vw rabbit. convert it to a vw diesel with a 5speed. NOW as for the smell it depended on what i was burning and that was never diesel. number ingriedient used french frie oil from the local pizza store number two used (filtered motor&tranny oil) number three scented candle oil. just imagine the smells when we stopped at a light. go for the sl thats what makes this country grow.
ps i got up to 60 mpg.

good luck
