In an average car, you would need about six liters of petrol to drive 38 miles. This is equal to about 1.5 US gallons.

This question is too ambiguous. Litres and miles are not similar measurement units. Litres measure volume, while Miles measure distance. If you want to know, for instance, the number of litres it would take to drive 30 miles, you would first need to know the petrol usage rate measured in litres per mile. A sensible estimate however would be around four litres.
your best bet is to drain it, it would be easier if it was the other way round, petrol into diesel but it not. either drive it to your nearest garage or pump it out by hand.
That would depend on the price of fuel, in the UK you would pay around £5.24 per imperial gallon of petrol (September 2010), that would cost around £18.88 to drive 90 miles.
None, if you cycle! If you drive, it depends on the fuel efficiency of your vehicle and your driving style.
500 miles is always 500 miles unless it's nautiical miles. I'm not sure if 500 miles in petrol would be classed as nautical miles.
It depends on the cost of said petrol and the efficiency of the vehicle in "miles per unit of petrol". You didn't supply enough information.
Depends on how you drive. If you drive mostly city, with short trips, I would recommend changing it every 4,000 miles. In mixed driving I would change it every 5,000 miles. If you drive mostly city change it every 7,000 miles. Of course I am assuming you drive a 2005 or newer vehicle. You can never go wrong by following the manufactures recommendations as listed in your owners manual.

I would recommend not running the engine until the fuel is drained. Any amount of petrol/gasoline in a diesel can cause engine or fuel system damage.
good luck finding a tank that holds 287 liters but it would travel 3172.1053 miles on that much gas!!!!
