Or go real old school like my 92 1.6TD... no ECU's, 1 wire runs the motor... Best tank was 1190 kms from a 55L tank vented to 58L... not bad for a 19 year old car. It's gone now but I bought a 92 Passat Syncro Wagon w/ a 1.9TD swap. 75L tank, ~6L/100km average mileage, large station wagon, all wheel drive, with a suspension lift. plus custom cam, giles pump, 2.5" mandrel DP. I swapped the stock cam back in because the custom one was giving me cold start issues. But with the oil pan heater and block heater, as long as there is a plug around, it starts awesome. I couldn't stay away from the diesels for long. Most people I know who have owned one, ALWAYS own a diesel again eventually.
