If you are noticing a decrease in fuel mileage, there are a few things that you can check. The first thing I would recommend checking would be the air filter. If the air filter is dirty, this will cause the engine to use more effort during running and therefore decreases fuel economy. I would also check the level and condition of the oil. If the oil is black or low, the engine will also use more fuel due to extra effort required. Finally, I would recommend checking the tire pressures. The tire pressure going low can cause a major difference in fuel economy.

If you`re wondering why your car is using fuel so quickly there are several causes to consider. Low tyre pressure, dirty air filters, overloading, and poor driving habits are just a few of the many reasons why your car`s fuel economy can suffer.
Many of the main causes for poor gas mileage are mechanical and include things like improper air flow, faulty injectors or bad oxygen sensors. “Your vehicle needs both fuel and air to give the best fuel mileage,” says Nicole Miskelley, manager at PMR Auto & Diesel Repair in Marion, Illinois.
The air volume hole of each oil system is partially blocked
Reason: partial blockage of air volume hole of each oil system will cause concentrated oil supply of carburetor and increase fuel consumption. Exclusion method: clean according to the above carburetor cleaning method.
Find the adjustment screws on the front of the carburetor.
There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. These often look like flat-head screws, and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carb.
When an engine misfires, it leads to poor engine performance, which in turn also affects the car`s fuel economy. Thus, bad spark plugs can decrease engine efficiency and force it to consume more fuel, thus increasing the car`s fuel consumption.
Air conditioning uses fuel
An air-conditioning (a/c) system can increase fuel consumption by up to 20% because of the extra load on the engine. The actual load depends on the vehicle`s interior size, the outdoor temperature and other conditions.
A car consumes more fuel in lower gears when accelerating. If the engine`s not pulling, shift down instead of pressing the throttle. Shifting up at 2,000 rpm (1,500 rpm for diesel) gives the best mix of speed and economy.
Typically, there`s a 12:1 or 15:1 ratio of air to fuel, and when there`s too much air or not enough fuel, it causes sneezing or popping sounds in the intake.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
If you`re driving at freeway speeds and notice your engine sputter or jerk, you may have a failing fuel pump. This problem is caused when the fuel pump can`t deliver a smooth flow of fuel to the engine; periodically, your engine receives only air when it was expecting to receive fuel.
Q: How Do You Tell if a Carburetor Is Rich or Lean? A: One way to tell for sure is by “reading” the spark plugs. If the plug tip is white, the mixture is lean. If it`s brown or black, it`s rich.
The idea is that by switching on your air recirculation button, and turning off the AC after a few minutes, you`ll use less fuel compared to keeping the air conditioning on constantly. The air recirculation button has an image of a car with an arrow inside it, reports The Express.
Symptoms of misfiring spark plugs include rough idling, uneven power when accelerating, and an increase in exhaust emissions.
Overheating. Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
Does AC affect gas mileage? As a general answer, a Consumer Reports study found that, yes, running the AC does reduce gas mileage. Here are some tips to help you balance your fuel consumption with comfort.
How much petrol does a car`s air conditioner consume per 100 kilometres? A car`s air conditioner consumes around 0.2 to 1 litre of petrol every 10 kilometres. A car`s air conditioner consumes around 0.2 to 1 litre of petrol every 10 kilometres.
One of the first signs of a failing fuel rail pressure sensor is poor fuel economy. If your car suddenly seems like it`s using more gas than usual, it could be due to a problem with the sensor. Additionally, if your car starts to hesitate or stall when accelerating, this could also be a sign of a failing sensor.
Frequent Idling and Sputtering
This means enough oil makes it through the filter as you drive but weakens when the car stands idle. In addition, if the car sputters when you drive at low speeds, the fuel filter likely has a minor blockage–a sign the need for replacement isn`t far ahead.
Generally, you want to shift gears when your car reaches 2,500-3,000 RPM. Eventually, you will know when to shift by sound and feel.
About 55 miles per hour is the optimum speed for most cars. Kick it up to 65 mph and you are 8 percent less efficient; at 80 mph you are 28 percent less efficient. Slowing down can also mean reducing your carbon footprint.
To check fuel delivery, remove the fuel line where it enters the carburetor and use a length of rubber hose to direct the flow into bottle or similar container. Fuel should pulse out in strong spurts if your engine is equipped with a mechanical fuel pump (electric fuel pumps are more of a steady stream).
Use carburetor cleaner to remove deposits, clogs & debris
Luckily, you can take care of many of these problems quickly and easily; often without even removing the carburetor from the engine.
Sometimes, your car may have the following symptoms: an irregular idle, poor fuel economy, lack of power, stalling, or a high-pitched hissing sound from the engine.
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls. If your check engine light is on and your car has been stalling out, you may have a fuel pump failure.

Should I buy this car for $1700
ANSWER : Prior to buying any car, drive the car around and listen for any noises. Then do an inspection on the vehicle to make sure that it is safe to drive. All cars will need maintenance, but if the car was kept up, then the maintenance should be to a minimum.

ANSWER : Hello, thank you for writing in. If the new battery has also failed to hold a charge, the alternator is likely not working correctly. You can test the alternator at home with a voltmeter, or you can remove it and have it tested at most automotive parts stores. It will need to be replaced if it has failed. You will also want to make sure all of the electrical connections are clean, dry, and tight. For more help testing or replacing the alternator, contact our service department to schedule an appointment.
I have to fill gas tank everyday due to car using alot of fuel
ANSWER : Hi there. There are dozens of problems that can lead to a drop in gas mileage, some of them are serious and some can be easily corrected. Here are some of the more common issues that can affect the fuel efficiency of most cars.On newer cars like your Sonic however, unless you’re driving more than 300 miles per day, you shouldn’t have to fill the fuel tank daily. Since the dealership has attempted to resolve this issue, you might want to have an independent professional mobile mechanic complete a car is getting worse gas mileage inspection to see if they can find the source of this issue.
Using E-15 fuel in my car do I need to use regular unleaded fuel maybe once in awhile or is it safe to continue to use the E-15?
ANSWER : E-15 is shorthand for gasoline blended with 15% Ethanol which is a fairly corrosive material which can cause damage to rubber parts and other critical parts over time. Ethanol also attracts and bonds with water from the air, and that water can separate out inside the tank due to phase separation. If your vehicle sits for long periods between use, the moisture settles to the bottom of the tank and can potentially clog in-tank pumps and filters. Damage is also possible in fuel lines, injectors, seals, gaskets, and valve seats as well as carburetors on older engines.
The main issue with respect to E-15 in many cases is whether or not the car will be covered under warranty from damage caused by using this product. GM and Ford have certified their own cars starting with 2012 (GM) and 2013 (Ford) to be compatible with E-15 and so some of the newer cars may not have any trouble with this.
I would not recommend using this fuel on longer drives where the chances of burning through an entire tank relatively quickly are greater. This may lessen the chance of excess E-15 fuel sitting in the bottom of your tank for longer periods of time where it may be prone to causing damage as outlined above.

the car is acting like its getting to much fuel. changed the fuel pump, fuel filter, and the fuel pump relay.
ANSWER : There could be a few things contributing to your problem. You are correct that clogged or sticking fuel injectors and possibly the fuel pressure regulator could be faulty. A plugged catalytic converter can also cause the vehicle to bog down. A failing throttle position sensor can cause the symptoms you describe as well. I suggest having a certified technician, like one from YourMechanic.com, do a few tests to determine the exact cause of your starting concern.
Fuel pressure
ANSWER : Hello,
You may want to try checking the fuel pump relay. The relay wires should have ground on two wires, power on one wire and switched power on another wire. To activate the fuel pump your ECU actually connects one of the ground wires to complete the circuit and send power to the fuel pump. If the wires all have power running through them, then it is likely you have a faulty relay. The wire coming from the fuel pump is the other ground wire. I would recommend having an expert from YourMechanic come to your location to diagnose your wiring as this can be very difficult and time consuming without the proper wiring diagram.

My car stutters after driving it for a few minutes – 2002 Toyota
ANSWER : This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire or stall. I would recommend having an expert from YourMechanic come to your location to diagnose your fuel pressure.
