about 2.75kg of fuel weight. (barcelona track - shortish) a gallon of gasoline weighs around 3.1kg. So depending on the specific type of fuel they use around a gallon an average racing lap. Seems about right. Considering supercars do around 5 miles to the gallon (1 lap) racing. Although a f1 car is faster it may use a similar amount of fuel due to weight and friction issues. f1 cars cut through the air more easily. It will vary depending on circuit of course.
The typical race of violent offenders is human.
No ... starting with the 2010 season, cars must start the race with a full load of fuel and are not allowed to refuel during the race.
The question of whether NASCAR should continue racing during oil crises has been broached on several occasions, namely during the oil shortages of the 70's as well as the price inflations of the 2000's. In the 70's races were shortened in an effort to save precious fuel. Today, this is less of a concern, as the fuel used in a typical NASCAR race is of a much higher octane and would be unsafe to use in a typical street car.
Roughly 72 liters per tank full. Average consumption is about 3km to a liter. They fill twice minimum during a race.
On average a NASCAR get 4-6mpg, so during a 500mile race they would consume 80-125gallons of fuel.

Depends on what type race car you are asking about. A top fuel dragster uses around 22 gallons of nitromethane for one run down a 1/4 mile track. A typical Nascar vehicle will get about 4 to 6 MPG. Other race cars are somewhere in between.
28 gallons of fuel
180 litres, I believe, however all cars are under-fueled for the race so the driver must save fuel to make it to the end of the race, but this also makes the car lighter in the early stages of the race.
A typical horse race usually has around 8 to 12 horses competing.
Refuelling is banned only during the race. It is not banned during qualifying runs. The teams can fill up as much fuel as they want and as many time they want during the practice and qualifying runs.
The average bike riding speed for cyclists in a typical road race is around 25-28 miles per hour.
