Slightly. Although compressor is always turning, when clutch engaged there is more resistance & more load on the engine. It's probably 3-5 mi. or so gallon difference dependent upon engine.

Is a car's mileage affected when the car's accessories are bing used?
Anything that puts an electrical drain on the system will lower fuel economy, also running the air conditioning will lower fuel economy.
How many filters does a tractor have?
oil, air, hydraulic, fuel, air conditioning,
Why does air conditioning use more fuel?
Because the air conditioning compressor, is run from a pulley off of the engine. This puts an additional load on the engine, which causes more fuel to be used.
Can a cold air intake make your car faster?
A cold air intake can either work for or against you... it can increase your horsepower, and thus lead to improved performance, but only if it still allows you to maintain the ideal stochiometric ratio (the fuel/air mixture)... otherwise, it'll decrease your power and fuel mileage.
What is the purpose of an air conditioning?
air conditioning is to condition fresh air so that the desired conditoins can be achieved in the conditioned space. air conditioning does not neccessarily mean to just decrease the temperature of air but it includes many more things like decreasing the humidity, increasing temperature etc etc.
Will a defective mass airflow sensor decrease mileage?
Absolutely. The MAF is what tells the engine the temperature, amount, and mass of the air coming into the engine. When it goes bad, the computer can't properly figure out air/fuel mixtures and MPG suffers.
What do a cars have now that they didn't use to have?
Air-Conditioning. Mirrors. Fuel Injection. ......

What happens of adjusting the fuel and air mixture at altitude is?

Why does fuel consumption increase when air con on in car?
Air conditioning uses a compressor to chill the freon that cools the air. The compressor requires a good bit of power to run- and places an additional load on the engine. This requires the engine to burn more fuel, and your gas mileage decreases. There is no free lunch- the power to run that compressor had to come from somewhere, right?
What is The basic purpose of adjusting the fuel to air mixture at altitude?
decrease the fuel flow in order to compensate for decreased air density.
