Cars loose freon by leaking past worn o-rings, old hoses can pass freon through the hose walls, leaks can develop in the condensor or evaporator coils, but the most common is the compressor fron seal. A good shop can use a "sniffer", which is an electronic leak detector, to find the leak. Some are VERY sensitive, detecting less than 1/10th of an ounce per year leak. Also, flourescent dyes can be injected into the a/c system which will glow under an ultraviolet light indicating where the leak is.
R134a is the only freon for cars after 1994. Earlier cars can be retrofitted to R134a.

freon
depemds on the car as how much freon it will hold. some cars have a tag saying how much freon the car is filled with. Too much freon is just as bad as not enough freon.
There is many different types of Freon. If the freon that you are trying to use is R-22 then you have to have a EPA certification to handle that freon. This freon is considered ozone depleteing. Now there is freon out there that is not ozone depleting like the freon in cars made after 1993. That is called R-134a which is sold everywhere even in Wal-Mart.
A leak is the only way to loose volume of the freon charge. Freon is in a sealed system and it does not get used up. If your system is tight the freon will last forever. However a restriction in the freon lines can cause the freon pressure on the low side to look like it is low but the freon is really stacking up in the condensor.
you use freon to cool your car and make the air conditioner work
It does not use freon. It uses R134A refrigerant, as do all newer cars since sometime in the '90s.
Yes All cars and trucks now use R-134A for A/C. Freon is just what they call the gas.
R 134a by Federal Regulations all cars have R-134a "freon" in the AC system since 1996 to present.
