Red Lights

When driving and you notice the red light in front of you coast to the light. Instead of getting there and breaking to a complete stop, gradually downshift. The best would be to slowly get to the traffic light without having to stop and luckily the light will turn green before you break.

FUEL Saving versus MPG inflating

For me, at least the goal is to use the least fuel (and $) for the driving I NEED to do - not just to max out MPGs. One tip - if you have two or more options for your daily round trip drive, calculate how much fuel (gallons) are really consumed over the (miles) driven. You may find the "least fuel" route is not the "highest MPG" route. Good luck.

Be Strategic

Look ahead at the stop light, if it's red remove your foot from the gas pedal and coast up to the stoplight for as long as possible. Smile and take pride that you saved yourself some fuel!

Cruise control

Use cruise control as often as it's safe. It's much better at keeping a constant speed than your foot.

Do NOT put your automatic modern car in neutral

There are a few tips here that suggest putting your car in neutral, however this can be counter-effective in some vehicles. When you let off the gas in most modern automatic cars the braking you feel is caused by the engine...when you let off the gas the car cuts all gas flow to the engine, the only thing turning the engine is the cars momentum. Shifting into neutral means not only that you lose engine brake(which to a savvy driver on the highway can essentially eliminate the need for regular brakes) but you also have to use fuel to keep the engine turning.

No one thinks of this tip

The mpg forumla is average miles / gallons used. So it makes sense to use less gallons to increase your MPG. Well one idea of consuming less gas is to car pool. Your distance keeps on increasing, but you still keep your gallons!

Momentum Tip!

When you look ahead and see the traffic light is red, you want to judge and have the most speed as possible when the light turns green. So use judgement. Keep your speed around 30mph, 25mph, 20mph, and then 15mph, and if it still doesnt turn green, then probably you have to stop. The idea is, you dont want to start from zero, because the avg mpg when accelerating is 10!

Avoid turning

The shortest distance between point A to point B = travel in a straight line. So when driving, avoid changing lanes.

Don't be in such a hurry to get where you're going; slow traffic, signal lights, inclement weather, etc. won't allow you to save any significant time anyway. You're just wasting fuel by dashing from one stop light to another, not to mention increasing your chances of getting a ticket or into an accident.

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.
