Fuel Saving Tips


Feel the Breeze

If it's a nice day outside, roll the windows down a little. Your A/C compressor eats away at your gas. In Texas, I noticed 7 mpg difference between the summer months and the spring/fall months as I was not using my AC during the fall or spring.

Watch Your RPM's

Despite common belief speed is not really connected to MPG. The Revolutions Per Minute (RPM) of your car's engine is what really matters. If your car has a Tachometer watch your RPM's, keeping them low will use less fuel. Depending on the gearing of your transmission is what determines how fast you travel at a certain RPM.

Don't cut in line

While not a tip to directly effect your gas mileage, it'll help everyone behind you. When on the highway try not to switch lanes erratically. This is essentially what causes traffic. The person you cut off will break (maybe slam on their breaks!) causing the person behind them to break...a little harder, etc. The same goes for when you're sitting in traffic, it's best to sit in one lane, and minimize breaking by keeping a slow constant speed. Your car will appreciate it, and by virtue of keeping people behind you from stopping you'll do a little to alleviate the traffic jam.

Ease off the brakes

The moment you see a stop sign or red light (or a turn you have to make, etc.) take your foot off the gas (and put it in neutral if you've got a manual). Let your car roll to the stop. People behind you may get a little annoyed and speed by you just to come to a stop but don't worry about them, because if you time it right, you won't have to stop at all, the light will be green (thanks to the person who sped in front of you and is waiting at the light) and you can keep driving. Use this in moderation obviously, since there are some crazy drivers out there, and I'd rather you be safe, than save a few bucks at the pump :)

Accelerate a bit...sometimes

Though some people will tell you never to accelerate quickly, sometimes it's better to have a bit of a lead foot. Seriously. There are two main reasons for this. First: your engine likely operates at a higher efficiency (i.e. burns more fuel that would otherwise be wasted by your catalytic converter and just go out your exhaust) at around 80% acceleration. Second: Your car gets better MPG at higher speeds up to about 55-65 mph depending on your car. So as long as there aren't too many red lights ahead of you, it's best to get your car to the maximum legal speed as soon as possible.

Walk the line

Go inside rather than use the drivethrough. If you idle for more than 10 seconds, you're using more gas than needed for restarting your car.

Coast...

Driving down a small hill? No need to hit the gas pedal. Just coast as long as you can while maintainign a safe speed.

Coast as much as possible

When it's safe, take your foot off the gas pedal completely and coast as much as possible. This is the equivalent of shutting off your engine, as you don't use any fuel at all when coasting.

Pump You Up

Keep your tires inflated to the proper pressure. Low tires mean more surface area, and therefore more friction, which translates to higher fuel consumption. Check your tire pressure while your car is refueling. If you need more air, pump up while you are there!

Stopped? Turn off your engine

If you're going to be sitting in your car with the engine running for more than 30 seconds or so, it saves fuel (which would be zero mpg at a standstill) to turn the engine off. Hybrids are famous for this, and it's a bit trickier to do in a regular car, but if you're at a long light, or waiting in a long line of cars, it does decrease fuel usage to simply turn off your car's engine.

Use Cruise Control Often

On steady flat roads (especially at higher speeds), cruise control can save a lot of fuel by limiting accelerations and generally resulting in a smoother, more efficient trip.

Keep Your Distance in Traffic

When driving in stop and go traffic, try to keep a couple car-lengths of distance in front of you to minimize the chances of having to come to a complete stop (which requires you to start again, using more fuel). By maintaining some distance and a steady very slow speed, you can carry your momentum through traffic and save fuel.

Don't drive

It's obvious of course, but a great way to save fuel on all the short errand trips you do from home is to either walk, ride a bike, or at the very least cluster your errands into fewer trips. Riding/walking will also keep you healthy as well as save money and fuel.

Keep Filters Clean

Changing your oil filter and air filters as recommended is a good way to keep your engine running more efficiently and saving more fuel. Oil changes are common but you might forget to change the air filter often enough. Try it and you may see an increase in power and gas mileage if it's been a while.

Kill the Jackrabbit

Punching the gas from a stop (aka "jackrabbit starts") is a great way to waste fuel. You can optimize gas by starting from a stop slowly and gradually. Generally, drive as if you are taking a baby home from the hospital -- smooth, slow, and careful, to save the most fuel possible.

Slow it down

As much as I love to drive fast, it's a fact that you're on the freeway and you are driving beyond 65mph, your fuel economy will go down. As much as I like getting home faster by driving 80mph, going 55mph saves several mpg.

Save weight, save fuel

Don't leave heavy items you don't need in your car's trunk or truck bed. Put away tools, golf clubs, skis, whatever and watch your mileage go up. I noticed my car lost 2-3mpg when fully loaded on a long car trip, and returned to normal when emptied.

Keep Tires Properly Inflated

You can improve your gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer. (from fueleconomy.gov.)
