If the tachometer measures how many times a minute the cylinders spin in the thousands, and lets say each cylinder has a capacity of 1/2 a liter, then how are cars able to go for hundreds of miles, why are they not out of gas within a few feet ???
Cylinders don't spin. Cars run on air more than gasoline. For every 14.7 mass units of air, roughly one unit of gasoline is required. Air doesn't exactly weigh much.
actually, tachometer measures flywheel rpms.
engine size in liters is total amount of liters displaced through all the cylinders in one work cycle, as in - all 4, 6, 8, etc of them.
each particular cylinder has not really that much displacement.
Also, like other poster said - air to petrol ratio is quite high, and engine is mostly running on petrol vapor, not liquid petrol.
A lot of effort is put into creating a better aerosol, as this improves performance and reduces petrol consumption. Latest developments are stratified direct injection engines, eg. the finer and better the mix, the more efficient the engine is.

Look at a video of an internal combustion engine. The gas vaporizes and explodes from the spark, sending the piston down. Each time that happens very little fuel is used.
A minuscule amount of fuel is used for each revolution.
