Fuel Saving Tips

Pump fuel at New Stations.

New stations have new pumps with filters etc. You will get the amount of fuel that you pay for and less air than an old pump and station. Furthermore the filters so cleaner fuel.

Hill Tip

Years ago we would put our cars in neutral if it was a gental slope to save on fuel, but today with fuel injection and not carbuerators, LEAVE YOUR CAR IN GEAR !!!! The reason is whith computer control many cars computers shut off the fuel flow as it is not needed to keep the engine turning over for all the power needed for steering, alternator, and etc. Plus it will save on brakes because the energy usd to keep the car going slower.

Tire Pressure

After you’ve clear everything out of your car that isn’t needed on a daily basis, get chalk or another type of marker and mark the entire width of each tire. Drive the car normally for a couple of miles. If no chalk is left across the tread, that particular tire is properly inflated. If the middle of a tire has no chalk but the edges do, it’s over inflated and under inflated if the outer edges aren’t chalked but the center is. Yes, we can improve mileage by increasing tire pressure but the tires will wear prematurely and they’re expensive. Additionally, the safety of all people on the road is more important than marginally better mileage.

Lower your vehicle weight to save gas

extra weight consumes gas so if you are travelling alone get rid of those extra seats. store them in the garage or basement when not used. you will save money. getting rid of the spare tire is a gamble. if you consider youself a lucky person then go ahead but other wise its extra weight is probably worth it.

Do Your Research, Use Your Head!!

Some of these tips are harmful to the vehicle if you intend to keep it long-term. Ask a mechanic what the inside of an engine started and driven cold under full load to 'save fuel' looks like. I will burn $0.50 worth of gas to make sure the engine is at temperature before tearing down the road in 4" of snow with 4x4 enagaged. Also getting killed because your windows are iced over isn't worth $1.00 in gas. It may be cool to be a 'hyper-miler' person on this board, but if you have to replace your car sooner the fuel you saved is irrelevant.

Always Park near the exit

It makes no sense to park all the way in, you have to come out, and this increase distance and reduces mpg. If there is no space, shut off the engine and park on the side and wait for a spot.

Drive behind a vehicle to decrease air resistance and increase MPG. Put the car in neutral when going down hill. If your going too fast, just slightly tap on the brake while maintaining space between the car in front of you.

Parking in Garage

Don't start the car, put the car in neutral and push it by the side while adjusting the steering wheel.

Put Auto Transmissions in Neutral

I've found that when sitting at long stoplights putting the car in neutral saves fuel over the course of a tank of fuel used. On many cars you can feel the load on the engine when in Drive but not moving. Sitting in neutral tales a lot of the load off the motor. Obviously this works best when you know the individual light you're sitting at so you can time putting it back on D without holding up those behind you or shock-loading the drive line.

Go by bike - Occasionally

When the weather is good, and the days are longer, take the bicycle for some trips. I've been managing to commute to work by bike at least 1 day per week (its 25km each way, so takes about an hour x2). I'm saving 20% on my fuel bill and feeling fitter. You could also just cycle part of the way - drive half way, cycle the rest. Lots of benefits, few downsides if you want to make it work.

Save electricity - Save fuel

Winter puts alot of strain on the electrical systems Some vehicles will increase the engine rpm to help maintain a healthy battery charge rate Some engine start to bog - causing the engine to adjust the fuel to keep it running So when sat at traffic lights - turn things off For example, put wipers to intermittent vs continuous Switch any front fog lights off temporarily - unless condition dictate you shouldn't Take your foot of the brake pedal and use the handbrake All minor things, but it also helps prevent low battery's due to lack of charge time

Engine Load, not RPM's save gas

Despite claims that RPM's are directly tied to fuel economy, it's not the full story. Engine load has a big part to do with it. If you're going up hill, you'll need more gas get up that hill. The best way to find the best combination of throttle & gear is to get a Scan Gauge, Ultra Gauge, ELM327, or any type of OBD2 scanner that can approximate instantaneous fuel economy. You'll get a hang of driving techniques to maximize economy by watching that number rise and fall. My preferred setup is a WiFi ELM327, & DashCommand for iPhone that will give you both estimated fuel spent, and a history of your current drive's mileage estimates.

Go WOT in turbocharged performance vehicles occasionally

Excessive low-load, low-RPM driving in turbocharged performance vehicles causes excessive carbon buildup in the cylinder and on the spark plug that can cause misfires and knock if left unchecked. It may seem counterintuative, but you need to burn off these carbon deposits occasionally by driving spiritedly for a little bit (note:obey all local speed laws).

Ensure your wheels are aligned correctly

Make sure the wheels on your car are aligned by a specialist who knows how to use his equipment. Insist on a written report of the appropriate toe in/out and camber for front and rear wheels and compare with the manufacturer's recommendations. This improves fuel consumption with reduce rolling resistance, improves handling and braking, and will extend the life of the tyres considerably saving further dollars. Inspect tyres regularly to see if tyres are wearing unevenly which would indicate the car requires another alignment. Bad impacts with kerbs or pot holes can affect alignment.

Anticipation saves - improvement

"... if you are going to have to stop that you take your foot off the accelerator and cruise up to the obstruction using your brakes as required." is an excellent tip. Improve on it, don't just cruise to the stop. If you are a good judge, hit the brakes early on, slow down, then cruise. You may not have to stop before the obstacle/stop light, and you will have more momentum as you start to speed up. Worst case you still come to a stop, no worse than cruising all the way and coming to a stop. Road rage caution: watch out for impatient drivers behind you, who will try to change lanes and zip in front of you. Stay calm, they will learn.

Buy fuel cheaper with dollar cost averaging

Save money at the pump by using a trick smart investors use to buy stocks. Instead of filling up at the pump, buy a set $ amount each time you gas up. This will always buy more fuel when prices are cheaper and less fuel when prices are higher. Over time you will average a lower price on gas purchases. guaranteed.

Hot Air Intake

Cold Air Intakes are for the movies. They look cool and are easy enough for the average kid to do in the driveway. All cars already have a snorkel that takes in the air from the "cold" area outside of the hood. Cold air can increase power density but more power means more fuel is consumed. And cold air creates more heat loss of the combustion just to heat up the air. I made a simple hot air intake that picks up off of the catalyst and runs at 140F.

Skip gears

In the UK, learner drivers are now advised to skip gears to get up to top speed quicker and more efficiently. On slight downward hills, it's easy to pull away in 2nd, when you reach 30 MPH, select 4th or take the revs a little higher and select 5th. From 0-60 you only need to change gear twice so the engine doesnt go through the full rev range in every gear. Similar patterns can be applied when dowshifting too.

Deactivate Cruise Control on Steep Downgrades

Newer cruise control functions will actually hit the brakes to maintain set speed if you begin to accelerate down a steep hill, so that steep downgrade that you think is really going to help your MPGs could be only helping a little. Turn your cruise control off if you think the grade is steep enough. Remember, the faster you have the cruise set to, the lesser chance you have of this happening, as drag naturally increases with speed, which will require your engine to maintain that speed even when going down the hill. The slower your cruising speed equals a greater chance that your car will pick up steam going down that hill.

over inflate tires at least 10% for more mpg

I have found that on my tires that are rated at 35psi that when I inflate them while hot to 44psi (suggested max for Mich Defenders) that I get about 10% more mpg. Honda civic VX and my Acura Rl.

The Power of Coasting

Don't forget that when you're coasting, your car isn't using fuel. The car's momentum is actually turning the motor with the friction your tires have on the road. Make sure to reclaim some of the energy you spent to get your vehicle moving by coasting. Pay attention to stoplights ahead, learn the light patterns, and you can easily bump your AVG MPG by at least 5. The more braking, the more you're decreasing your fuel economy by turning that energy into heated brakes. Don't waste the energy you spent getting up that hill by excessively braking while going down. Drive safe, but keep that fuel economy in mind!

Choose right vehicle

Use right vehicle for the work. For example, for city commuting in good weather, if you not need to carry much cargo with you, you can use a motorcycle, or even cub-bike ( underbone, step-throught) for commutiong. You have a big win throught that - no rush hours ( who consume your time and fuel), and much less fuel consumption - on my one chinese underbone i get into 2 litres per 100 km! my 600cc motorcycle get around 5 - 6 litres per 100 km in city, and my car - around 8 - 9 litres to 100 km. and there is a rush around...

Turn A/C On While Traveling Downhill/During AFC (Free A/C)

On a modern car, auto fuel cut off will be activated when you remove your foot from the accelerator while traveling downhill. If you want free intermittent A/C turn it on while traveling downhill or slowing down with your foot off the accelerator. You may feel a very slight increase in engine breaking when you turn the A/C on but it is minimal. There is a kit available online that activates the A/C when auto fuel cut off is activated (I don't know where you can buy it as it was a while ago).

Partialy Block Off Your Radiator Grill.

This especially applies to diesel vehicles. The sooner your engine gets up to temperature the more efficient it will be. For example my (diesel) car gets almost half the MPGs it would get when up to temperature. I have blocked off the lower grill (with black duct tape) which allows my car to warm up faster and keep a sturdy temperature. This also improves aerodynamics of your vehicle (if done correctly). I am doing this in about 6-15 Celsius weather and see a decent increase in MPG and I can also use my heaters earlier. IMPORTANT Be sure not to block off your intercooler (if fitted) as this helps MPG and keeps intake air temps low and intake air density higher. It is extremely unlikely your vehicle will overheat but for the first few journeys keep an eye on your coolant temp.

tire pressure

the recommended tire pressure is listed on the inside of your drivers side door, Front and Back check it often the seasons are changing and so is your tires air pressure. NOTE check it before you leave, Not after its been driven or if its been sitting in the SUN for a while.

Avoid Stations Taking on Fuel

If you see a station being refueled or you know it has been refueled in the last couple of hours, go somewhere else. The turbulence from refilling the storage tank can kick up any muck and water laying on the bottom of the tank.

Keep that diesel fuel tank full

Diesel fuel is highly hygroscopic. That means it sucks moisture and water out of the air, on a daily adiabatic cycle. The more air stored in the fuel tank, the more moisture is drawn into the fuel tank, condensing on the inside walls of the fuel tank, as the tank breathes in and out with the daily heat cycle. Keeping your diesel fuel tank fuel limits the amount of moist air drawn into your fuel tank, and into your fuel during humid seasons. This is less a problem in the arid SouthWest seasons with relative humidity below 20%
