Why not, especially if you have a mixture of say 50/50 (this can also 
depend on the weather which can seriously affect the viscosity), there 
are many things that a modern diesel engine will run on and last beyond 
what the rest of the car will normally manage, so long as the additives 
that provide lubrication are added in every so often or are in there all 
the time even in diluted form.
