By coincidence, this afternoon I came across a warning label attached when new to a S3 diesel that I have. I think it is worth quoting in full:-Quote:

The whole engine must be raised above the critical temperature before starting and normal diesel fuel used to replace the above mentioned fuel, after which the vehicle can be safely started in prevailing conditions. The engine may be considered as satisfactory for starting when, upon undoing the vent screw on the distributor pump, liquid fuel may be pumped from the tank by operating the fuel pump hand priming lever.
This certainly suggests that you will get problems if you use fuel with too high a viscosity, but also tells you how to tell whether you have got too high a viscosity.
