Thread: TD5 fuel economy and leaky pressure regulators

???? logic says every drip that leaks out is a drip that is not going to the engine to be burnt and turned to motion. Motion = distance however small.

By my maths this equates to a bit more than 11L per 100km

Is this normal for a TD5?

The above was achieved whilst my pressure regulator continued to drip in its usual frustrating fashion, anyone want to comment on how much the overdue replacement that I keep putting off will effect the above figures?

Soooo...
*calculating fuel consumption really doesnt make any sense with fuel leaking out of the fuel system
*whats the problem?
*are you comparing 11L/100km to what?
*has fuel consumption gone radically bad?
*have you had the disco long?

if we are talking fuel consumption in the suburbs for an average size 4x4 common rail turbo diesel engine.... then there is nothing to complain about with 11L/100KM.
In general terms, the TD5 engine is quite fuel efficient.

In order....

*whats the problem? - see above
*are you comparing 11L/100km to what? - mythical(?) 10L per 100k of the TDI and anyone else's figures that might be posted for other TD5s - hence the thread
*has fuel consumption gone radically bad? Not yet
*have you had the disco long? 2+ years, it replaced a Classic RR running twin Strombergs so fuel consumption is all relative

So Just how efficient are the TD5's of others? Over to you
