[Vwdiesel] Honda diesel MPGs

[82 Diesel Westy]

Mercedes calls their Direct Injection Diesel a CDI,
but still a common rail / pump design, strait 6 motor.
I do think VW has a registered trade mark or something
on "TDI"

"The "CDI" designation in this E-Class encodes
breakthrough innovations in diesel technology. The
letters stand for "common-rail direct injection" which
in this 3.2 in-line-six serves to transport the
inherent efficiency of diesels into even greater
efficiency. The fuel metering system manages to
deliver to the engine (in concert with the Variable
Nozzle Turbine or VNT turbocharger) the optimum amount
of fuel needed for the task of the moment and is
laboratory precise."

I must admit, Mercedes makes the best diesel in the
world when it comes to cars/trucks, but out of my
price range unless 25 years old and 250K miles.
