That would depend.
The Law of Conservation of Energy applies here. If energy is being used to do something (play the radio, run the defroster, anything that requires energy), then the energy has to come from somewhere. If you're running the defroster, that means the fan is running, which runs on electricity, so the alternator has to provide the electricity to run the fans. The alternator gets its energy from the engine, which gets its energy from the burning fuel (actually small explosions, the expanding gas pushes against the cylinder, forcing it to move. The cylinders are linked together to help turn the shaft and the pulley that drives the belt which runs the alternator, air conditioning compressor, and a couple of other things.
Now the heat that is blowing out of the vents, does not necessarily cost any more gas. The heat was generated by the engine's burning of fuel. The hot water from the radiator goes to a heat exchanger where air is blown past, which heats up the air. This will cool down the water some (Conservation of Energy again). If the air heated up, then that energy came from some where (the water). So since cooler (relatively) water is running through the engine's cooling system, the engine will run a little cooler. Now the question is: is there an optimum temperature for the engine to run at to achieve optimum efficiency. I believe there is, but does using the heater cool down the engine temp away from this optimum temperature (decreasing mileage), or move it toward the optimum temperature (increasing mileage..
What else can I help you with?
Does using the defroster in your car use more gas?
yes, it works just like the a/c, it just blows the air on the windsheild/windows
How can I optimize my vehicle's gas mileage using a gas chip?
Using a gas chip can optimize your vehicle's gas mileage by adjusting the engine's performance to be more fuel-efficient. This can result in better fuel economy and savings on gas costs.
Does using the defroster affect gas mileage?
Yes, it will decrease fuel mileage slightly. Reason being is that on all modern vehicles when the defroster is run the A/C compressor is also running. The compressor is driven by the engine and this extra load on the engine will require slightly more fuel. The benefit provided by the defroster far outweighs the slightly more fuel you will use.
How long is the drive cycle on a 2004 automatic transmission ford focus?
All you have to do to "trick" a reset is the following; 1. The gas has to be between 1/4 and 3/4 full. Not above or below. 2. Start the vehicle and put it in drive and hold the brake. 3. Turn on the air conditioner and the rear defroster. 4. Sit in drive for 2 minutes. 5. Turn off AC and rear defroster. 6. Drive the vehicle up to 55 mph. 7. Decellerate down to 20 MPH, do not touch the gas or the brake. 8. You must do this 3 times and let the vehicle get cold between cycles.
Can you really save your gas money when using a vehicle gps system?
Yes you can really save gas money when using a vehicle gps system. It helps save time and gas when looking for a place. Instead of wasting gas and time looking for the place without knowing anything, with the gps it helps get you to your destination without any hesitation.
How much gas would you need for 875 Miles?
Depends on vehicle mileage you are using for the trip
How do you start a diesel engine after it runs out of gas?
Refuel the vehicle using jerry cans and restart the engine. It will likely take more than one, depending on the size of the vehicle and how far the nearest gas station is.
What is the formate for no objection letter for using vehicle?
Not is gas formate super glue potato diesel no objection.
Does using the defroster to cool the car save on gas?
Using the air conditioner never saves fuel. But if you are going to use the air conditioner it is better at highway speeds than having the windows rolled down. In the city is better to turn the AC all and open the windows.
Electric Vehicle Motors?
Electric vehicles combine a duel power source to move the vehicle. They combine a gas engine with an electrical motor. The engine works by using the electrical motor to assists that gas engine when it is needed. For example, when coasting, a normal car would use gas to power itself. But in an electric vehicle, the electrical motor is used in this instance because the gas is not needed, rather the electrical engine is used to power the vehicle and save gas.
What are the benefits of using a bicycle gas engine kit for converting a regular bicycle into a motorized vehicle?
Using a bicycle gas engine kit to convert a regular bicycle into a motorized vehicle offers benefits such as increased speed and range, reduced physical effort required for long distances, and cost savings compared to purchasing a new motorized vehicle.
