In response to a similar query Honest John replied:
You can usually get away with up to 10 litres
of petrol in a 60-litre tank. Fill up with high-lubricity diesel (such
as Shell V-Power Nitro Plus) and keep doing exactly that. Don't allow
the tank to be more than half-empty for about 2,000 miles.
At first, the petrol will float on top of the diesel and won't get
sucked into the low-level fuel pick-up. Then, very gradually, it will
disperse into the diesel fuel. But if she put in more than 10 litres she
needs to have the tank drained.
If any of the petrol has reached the
high-pressure injection pump, she will be in trouble. You can't fill a
current Ford, BMW or CitroĆ«n diesel with petrol because the filler
orifice will not allow it.
