The answer to this depends on several factors.The type of car you drive. If you have an "older" car the gas mileage will be less or a larger car it will use more gas.The cost of the gas. The price of gas varies between cities and areas. So you may fill up at home and find the price higher where you drive to.How fast you drive. The faster you drive the more gas you will use.Physical condition of car. If it has been awhile since your car was serviced gas use goes up.How much you carry in your car. If you have a lot of stuff/people in the car the gas mileage goes down. Weight equals gas usage.

No. A car heater gets its heat from the motor and uses no extra gas at all, unlike a car's air conditioner which does use more gas.
street Vehicles use more gas on the street and less on the highway. Unless they are hybrids. Hybrids use more on the highway than the street.
You will use more gas when your air conditioner is running.
The larger the car, the more gas it needs to go anywhere
