I seem to get mixed results out there, but generally on an average you get
27 to 29 MPG of the AAZ Turbo Diesel and 30 to 32 for the AHU TDI, not
enough results for the ALH TDI. My two previous AAZ TDs got about 9L per
100km on heavy syncros with 29" tall tires and heavy foot driving. This
translates into 26MPG - still much better than the 16 to 18 MPG for the
stock motors!

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...
