what makes a car run out of gas quick?

Question

I always drove a car cautiously with a little usage of air conditioner and stereo system and I draw a conclusion of my experience by doing that would save gas usage to drive 4 days and get gas instead of 3 days and get gas. Is it true? If not true then what makes a car run out of gas quick for 3 days driving as stated above?

Answer 1

Using the air conditioning does not have anything to do with gas mileage. The reason why ppl think that is because when you use your air conditioning it draws cold into the car while at the same time keeping SOME HEAT on the engine. But there is not enough heat there to make a difference on you r MPG. The first guy is right, flooring it will take a lot more gas especially if it had a carb. The best thing to do it to not 5 dollar your car. What i mean by that is to not let the tank get to 1/4 of a tank anf only put 5 dollars in it. It IS proven that if you keep your tank over half full all the time then you will get better gas mileage.

Answer 2

driving with your car windows down uses more gas than driving with the a/c. The stereo does not make any difference at all. The biggest thing that will make a change is your RPM's. if you rev the engine a lot , floor the car till you get up to speed or drive over 70 mph then you are going to use more gas.

Answer 3

Not using the stereo will not make any measurable difference.
Not using air conditioning, only a few MPG.
You're expecting too much from the changes you made.
