I have a stickshift car, when I am going down a steep hill and I am in gear, but not pressing the gas (engine braking), is the car using up fuel? The RPMs are high (4000-5000) because of the car going downhill in 3rd gear, but I am not pressing on the gas. I need to know this so I can save more money on gas.

Yes it is using gas. It's not using as much gas as if you were opening the throttle and actively feeding gas to the engine, but it is using gas.
If your goal is to save gas, this is not the best place to look. Accelerate slowly, keep revs low, and look far enough ahead while driving to minimize brake usage when possible. Keep your tires properly inflated. Keep unneeded weight out of your car while driving. Use a less viscous motor oil if possible. Make sure your air filter is not overdue for replacement. And if the extra RPMs from coming downhill are a concern, be concerned first with the extra gas used driving uphill! Look for alternate routes that are more level. Any of these will make a bigger impact on your fuel consumption than anything you could do differently while driving downhill with the clutch out.

a great form of those solutions might properly be actual. automobiles have assorted aspects to maintain the motor vehicle idle. Engines want air and gas at equivalent ratios. To me, evidently like your air consumption. There are small vacuum strains which permit the chambers to "breath". additionally there are PCV valves which alter the circulate the engine block. in the previous doing a gas injector cleansing, next time you replenish your gas tank, put in a extra robust octane. relatively of 87 fill it with a 89 or the subsequent step up from what your automobile demands. Thencontinual it on the line for a at the same time as to bathe it out slightly. the better the octane, the warmer the combustion interior the chambers, the extra "gunk" gets wiped sparkling out. continually take the smaller steps in the previous you're taking it to a mechanic. suitable advise is to circulate to an vehicle areas shop and purchase the troubleshooting e book to your automobile.

car engines typically idle at 500 RPM's, which is very little gas. As the RPM's of the engine go up, so does your gas comsumption.
Need more info on your car to see what we can improve on mileage.

If it is running, it is using gas. And engine braking causes the engine to turn, so it's using gas. Not as much, but some.
I've heard the argument that turning it off will cost more, as you need to push the gas to restart.
At any rate, the gas usage is minimal.

if the car is idling then yes it is using gas as for engine braking it reduces the wear on your pads and rotors but actually increases your fuel consumption since your engine is running at higher RPM's.

Anytime the car is running it is useing gas. Make sure your car is tuned up and the fuel, and air filters are claen. Run a feul injecter cleaner every fourth or fifth tank of gas, and do not drive like you are in a race.

Yes. As long as your engine is on, you will be using some (even if it's a small amount) of the gas in your tank.

I turned the idle screw up to 2000 rpm on my car and I have never had to put gas in mine since the first tank. That was 63,000 mile ago.
