DTE (Distance to empty) uses a different algorithm to l/100 calcs...
I can average 10l/100km and have 100km DTE. I then boot it (instant fuel at 27l/100 etc) for a small period and it and this will drop to 30km DTE.
Average fuel consumption still holds around 10s :cool:
On longer runs I often fill up and have a DTE of 570-580, only to have this number increase for the first hour of cruise mode highway driving..
I see no reason to miss a dipstick, the mechanical device is no more calibrated than a sensor, and it certainly can not warn you when it gets below safe limits (old oil lights meant no pressure, where as the electronic oil sensor can report low levels).
And the best line - I'd be pretty upset if I was driving my D4 around so low on fuel that I ran out ;) Every fuel gauge is an indicator - the vehicle isn't pretending to be empty - for all intents and purposes it is empty...
You would be more ****ed off standing on the side of the road.
Just as a dipstick doesn't indicate the engine is empty of oil - just below what it should be. Several vehicles will now go into limp mode and then commence shutting down if oil is dropped or pressure drops.
