What kind of MPG would you be expecting from the 1.9
TD? What kind of mileage would a TDi conversion
produce? Or for that matter, does anyone have any MPG
data for any of thier conversions? (or even stock)
I'm thinking fo going the 1.9td with my Double cab.
thank for the info- it's really nice to hear that kind
of input...
