As gas prices continue to rise, increasing gas mileage is the best way to protect your pocketbook. These are some ways to spend less money on gas by increasing the efficiency of your car when using it.
Method 1 of 4: The Cart
Step 1. Keep the car tires properly inflated
Properly inflated tires can reduce fuel consumption by up to 3%. Tires also lose about 6.9 kPa (1 PSI or pound per square inch) of air per month, and when they are cold (for example, in winter), the pressure drops due to the thermal contraction of air. It is recommended to check the tires at least once a month, preferably once a week. Having properly inflated tires will also help you avoid uneven wear on the tread.
- Some gas stations have automatic air compressors that stop at a predetermined level. (For safety, double check the pressure with your own pressure gauge, especially if the other measurement suggests that you put a surprisingly large amount of air in the tires.)
- Small extensions to the valve stem that are permanently installed may allow the tires to be filled with air without removing the plugs, but check that the extensions themselves are not prone to leakage or getting stuck with foreign matter.
- Recommended inflation pressures are for cold tires; It's best to inflate them first thing in the morning or have driven less than 2 miles (3 km) for your readings to be accurate. If you've driven for a long time or it's hot outside, add 3 PSI. Inflate according to the pressure recommended in the car manual or on the sticker located on the driver's door frame. Keep in mind that the reading printed on the tire is the maximum pressure, not the recommended one.
Step 2. Tune up the engine
A properly tuned engine maximizes power and can greatly enhance fuel efficiency. But be careful, as many tuners will disable the efficiency measures when tuning the power.
Make sure to keep the engine spark plugs in good condition, change the oil when necessary, clean the air filter, etc
Step 3. Check the condition of the engine air filter
A dirty filter will reduce fuel economy or cause the engine to stall when the car is stopped. Like mowing dusty grass, driving on dusty roads will clog the air filter. Avoid dust clouds.
Step 4. Replace the fuel filter according to the schedule recommended by the car manufacturer
This will do a lot to enhance fuel efficiency.
Step 5. Lighten your load
Get the lightest car that meets your needs. Weight is one of the main causes of kinetic energy loss in non-hybrid cars. If you're not buying a car, take some of the extra weight off your existing car. If you can remove the seats you don't use, do so. If you use the trunk as a storage space for heavy items, find another place for it. An additional 45 kg (100 pounds) increases fuel consumption by 1 to 2%. (Weight is the most important when driving with frequent stops. If you drive almost exclusively on roads, this matters very little: once the car reaches the desired speed, it should only push against the air). Do not remove things from the car that you need frequently; Instead, make sure they are in the car and easily accessible, because the trips you make to retrieve or replace them will be far worse than slightly lower gas mileage.
Step 6. Select the narrowest possible tires for your vehicle that meet your driving style and your demands
Narrow tires have a smaller frontal area, thus reducing aerodynamic drag. However, remember that narrow tires also have less traction (which is why racing cars have such wide tires). Don't get a tire that's incompatible with your wheels (use the ones that came with the car) and don't get smaller wheels unless approved by the manufacturer.
Step 7. Choose tires made of low rolling resistance compounds
These can increase fuel economy by a certain percentage. However, the difference is neither alarming nor a substitute for proper inflation. It would be a waste to replace old tires with these before they wear out.
Step 8. On cars with fuel injection systems, make sure the oxygen sensors, engine emission system, and evaporative emission control systems are in good condition
Often times, if the "check engine light" comes on, it is an indication that there is a problem with one of these components. A damaged oxygen sensor can cause your car to have too strong a fuel mixture, which will decrease fuel economy by 20% or more.
Method 2 of 4: Save Fuel
Step 1. When filling the tank with fuel, fill it halfway and try to keep it above a quarter full
Running low on fuel could put pressure on the fuel pump. 10 gallons (38 liters) of fuel adds a weight of 60 pounds (27 kg). Consequently, a half-filled tank can increase the performance of the car.
Step 2. When changing the oil, add a synthetic additive to the oil either natural or synthetic
This can increase your fuel economy by up to 15% if you follow the manufacturer's instructions and recommended usage. Note that the usefulness of this is questionable: the synthetic oil "additive" might be unlikely to cause a car to work less hard. This would not make the overall oil much less viscous, and circulating the oil is only a relatively small task for a car engine.
Step 3. Buy quality fuel
No fuel is the same, and while "discount" brand fuel can save you a few pennies per liter or gallon, it may contain a higher percentage of ethanol, which burns at a much faster rate. Compare the performance between different brands of fuel and find out what is best for your car.
Step 4. Avoid using the air conditioning when driving with frequent stops in the city, as this causes the engine to work hard and consume more fuel
However, studies show that, at highway speeds, cars perform slightly better with the air conditioning on and the windows closed. Resistance from windows open at high speeds reduces fuel efficiency more than air conditioning.
Step 5. If you are trying to find a direct way to control the amount of gasoline you use, monitoring how hard the engine works is key
Of course, air conditioning, acceleration and speed affect the work of the engine, but these are not direct indicators. Try to monitor the RPM (or revolutions per minute) at which the engine is running. It's like monitoring your pulse to find out how hard your heart is working. You will find that there are RPM ranges that are ideal for your car and others that are not.
- If you find that the engine is running over 3000 RPM, you may be accelerating in an unnecessarily low gear. So loosen the pedal and let the engine progress up to a higher speed at a lower RPM. The lower the average number of RPM you travel at, the less the engine will work, and this directly determines fuel economy.
- How do you monitor your RPM? Most cars have an indicator to the left of the speedometer, called a tachometer. This measures your RPM on a x1000 scale, which means that if the gauge is between 2 and 3, the car is running at 2500 RPM. A comfortable or efficient RPM zone is between 2000 and 3000. However, try to stay as low as you can below 2000 and not too much above 2700, unless necessary, such as going up a hill if you are stopped in a traffic lights. This means that you will not reach more than 65 km / h (40 miles per hour), although not necessarily, and you will reach between 80 and 88 km / h (50 to 55 miles per hour) in the city and up to 105 km / h (65 miles per hour) on the highway while still running at 2500 RPM. Try to find your efficient zone and maybe you can get a few more miles per liter by observing how hard the engine works.
- Please note that some carts are monitored by x100.
Method 3 of 4: Your Driving Habits
Step 1. Use the speed control
In most situations, using cruise control reduces fuel consumption by maintaining a constant speed.
Step 2. Slow down
The faster you go, the harder the engine will have to work its way through the air. Speeding can reduce fuel efficiency by up to 33%. Factors other than air resistance reduce fuel economy when the car is below 60 mph (95 km / h), so fuel economy is not a reason to slow down, but fuel economy Fuel drops rapidly above that speed.
Step 3. Increase speed gently at moderate acceleration
Engines are most efficient with moderately high airflow (throttle) and at revolutions per minute (RPM) reaching their peak power (for small and medium-sized engines, this is generally somewhere between 4000 and 5000 RPM). On a manual transmission car, practice upshifting as soon as you reach your desired speed by skipping the intermediate gears. For example, accelerate to 65 km / h (40 miles per hour) using first and second gears, then shift directly into fourth (skipping third) or, if the engine can maintain your speed, into fifth. (Be careful because, if you have to put the pedal to the metal in fifth gear to maintain speed, you should be in fourth!).
Step 4. If possible, avoid braking
Braking wastes energy from the fuel you've already burned, and accelerating after braking uses even more fuel than driving at a constant speed. On city streets, look ahead and neutral when you see a red light or traffic ahead.
Step 5. Avoid idling excessively
Leaving a vehicle stationary wastes a significant amount of fuel. The best way to warm up a vehicle is to drive it slowly until it reaches the proper operating temperature. However, in very cold climates, it is still advisable to idle the engine for a minute or two before starting to drive.
Step 6. Find the "ideal speed" of your car
Some cars perform better at specific speeds, usually 80 km / h (50 miles per hour). Your car's "ideal speed" is the minimum speed the car is traveling in the highest gear (watch for drops in RPM as you accelerate to determine when the transmission is upshifting). For example, most Jeep Cherokees run best at 55 mph (88 km / h), and Toyota 4Runners run best at around 50 mph (80 km / h). Find the "ideal speed" of your vehicle and, according to this, choose the tracks on which you are going to drive it.
Step 7. If your car has an automatic transmission with overdrive, be sure to enable it except when towing very heavy trailers
Overdrive is enabled by default with the "D" on most shifters. Several cars have buttons on the lever that allow you to disable the overdrive shift. Do not disable it except in specific situations where disabling may be necessary, such as braking the engine downhill or failing to proceed smoothly uphill in overdrive. Overdrive saves you fuel consumption per mile at higher speeds by using a higher gear in the transmission. For example, for every 3/4 turn of the engine that enters the transmission, the output is one.
Step 8. Don't circle through a parking lot and stay well away from store windows
Find a spot in the empty half of the parking lot. Many people spend significant time standing still waiting for a "nearby place" to be free.
Step 9. Keep a safe distance from the car in front
Don't stick to the fender of the car directly in front of you. You will brake more and accelerate more to keep that unnecessary and dangerously tight space. Relax and stay behind. This will also give you a lot more space when calculating traffic lights. When the driver ahead of you slam on the brakes, you can move into neutral and see if the light quickly turns green (some do). You can even pass that car in neutral just when the light turns green and it will have to accelerate from a complete stop.
Step 10. Avoid turning in oncoming traffic
If your route allows it, try to make as few left turns as possible while heading to your destination (or right in countries with left-hand traffic). Stopping and waiting at an intersection to make a turn in the next lane will allow the engine to idle, which wastes fuel, as well as speeding up again to make the turn.
Method 4 of 4: Plan Ahead
Step 1. Plan your trips
Have lists of what you will need on a trip and try to achieve multiple goals with each trip. This won't increase your gas mileage (the number of miles your car travels for each liter of fuel), but it will help you drive less (which, in turn, means you use less fuel).
Step 2. Plan your route carefully
Take the route with the fewest stops and curves and the least traffic. Wherever possible, prefer roads to city streets.
Step 3. Keep a record over time of how many kilometers you drive (the main odometer) and how much gas you fill (from the fuel pump, including fractions)
Put this information on a spreadsheet. This will help you stay focused, plus the other methods are not exact; You will never know for sure if you are saving fuel, wasting it or just seeing errors caused by fuel pumps that stop pumping at different points, or by fractions of kilometers that disappear from your trip odometer when you reset it.
- Fuel economy mainly depends on your driving habits. Drive safely and you will notice a difference.
- If your car has a roof rack, remove it when not in use, if possible. If the entire unit cannot be removed, remove the cross bars to reduce frontal area and drag.
- Prevents carbon deposits from building up in the engine. Do this by revving the engine to high RPM about once a week. On the roads and when you pass vehicles are good times to do this.
- Try to schedule your trips and manage when traffic is light. Doing this will also contribute to your mental health, as it will decrease the amount of stress you will experience while driving.
- A little weight in the trunk, like a bag or two of rocks, can be good in the winter to improve traction in rear-wheel drive vehicles. If traction is necessary, the added safety for people and property is more important than the slight expense of fuel. Just take the weight off when it's no longer needed.
- When waiting in line at a drive-thru or in lines to refuel, don't leave the car stopped. Turn it off and on again when it's time to move on.
- Vehicles with ground effect, aerodynamic kits and aerodynamic blades, such as deflectors for the boot lid, increase the resistance of the car, thus reducing fuel economy. Often such attachments serve only cosmetic value and offer no handling enhancements. It also places signs or cargo on the roof so that the smallest surface of the piece is facing forward. This will decrease the frontal area and therefore create a lower resistance.
- On cars with "economy" modes versus "power" modes, the "mode" changes the throttle response curve. You generally have the same power in "economy" mode if you hit the gas hard, but when you don't, you have more control at the lower end of the throttle input.
- Some cars that have a crooked shift pattern for the automatic transmission with the shifter on the floor have the "4" and the "D" in the same row. Many people shift through "D" all the way to "4" because that's what "feels good" and then they drive down the highway complaining of poor gas mileage.
- Manual transmissions tend to get better fuel efficiency, generally accounting for 15% of the power loss through the powertrain, while automatic transmissions consume around 20% of fuel in parasitic losses.
- Driving near another car is always unsafe; pursuing it closely is even more so. Driving near another car also has legal effects. Other hazards include the car in front of you stopping or stopping suddenly, changing direction to avoid something on the track, passing over something on the track that your car does not have enough ground clearance to pass, lifting debris on the road. track or have an accident. Always keep a safe distance from cars.
- Generally, a 3-second safety distance is most effective in maintaining a safe distance and avoiding hazards on the track even if they are hidden by the vehicle in front of you.
- Be careful when using oil additives, as some can invalidate your warranty. Read the back of the packaging before use or check with your vehicle's manufacturer.
- Beware of chipping and other minor appearance modifications, but still significant to the vehicle. These will definitely void your warranty, and improper modification can waste fuel and damage expensive engine components, causing problems for you.
- Beware of quack remedies and incredible savings testimonials. All the magnets and wonder gadgets that were discredited in the '70s have returned to tempt a new generation.
- Driving slowly on the road can be more dangerous. Generally, it is illegal to drive more than 25 km / h (15 miles per hour) below the posted speed limit without flashing your hazard lights.
