Fuel Saving Tips


Keep Track of MPG on Every Tank

Keeping track of the MPG on a vehicle at every fill up will help identify if the efficiency is deteriorating, or if one brand of fuel is consistently giving better MPG than another. This may also give you an early warning if something is not right with the vehicle such as low tire pressures, need or a tune up or maintenance, or a dragging brake caliper. Fuelly.com is a great tool to track and chart the MPG data over time, but that's why we are here right?

Brakes not working.

If you drive as though your brakes have failed you will find that your anticipation, awareness of other vehicles and control of your speed all improve, all leading to better mpg.

Automatic transmission *might* save fuel

When you're planning to buy your next vehicle, be prepared to let go of that old belief that a manual transmission will always deliver better fuel economy. Some of today's sophisticated automatics *might* be more fuel-efficient than a mindful and skilled stick driver. Do your due diligence before buying. (Note: Even though a specific automatic transmission *might* be more fuel efficient, you might never recuperate the additional cost of the automatic transmission with fuel savings.)

Use your cruise control!

The best way to maintain efficient driving on the freeway is to use your cruise control. The cruise control maintains a set speed and makes very minor changes to throttle position. It eliminates the "rubber banding" that people do on the freeway, the constant +/- 5mph that end up causing traffic jams, and ruin your fuel mileage.

Throttle Control (Roll On/Off)

Abrupt changing in throttle position (gas pedal), such as pressing quickly and letting off quickly on the gas pedal cause increased fuel consumption. Try rolling on and rolling off the gas pedal when accelerating and decelerating. This will improve your anticipation and also reduce how much gas your car is using. Over a full tank of gas, you can see between 2-3mpg improvements using this technique.

Freeway Driving Tips from a 27y/o Car getting 51.3mpg

- DRIVE 53MPH IN FAR RIGHT LANE. Other drivers will think either theirs or your odometer is inaccurate a tiny bit and won't be SO upset at your slower speed. - DRIVE 5MPH SLOWER UP FREEWAY GRADES. Stepping on the gas to maintain freeway speeds to climb a freeway overpass destroys your MPG. - SUNSCREEN YOUR BACK WINDOW. This prevents other drivers from intimidating you into driving faster by riding your rear bumper. If they know you can't see them they can't bully you.

keep your distance !

The gap to the car in front should be at least 2 seconds on a dry road. And if you're the 3rd car in a line and the 2nd car is only 1 second behind the lead car, then you should be 3 seconds behind the 2nd car. Someone else may sneak into the gap you've left - let them and don't get caught in their accident. And double the gap when it's wet.

Anticipate Traffic!

If your are driving and see tail lights come on in front of you, the traffic is stopping. Don't keep on the throttle trying to play Tetris with your vehicle. You won't gain an inch. Take your foot off, coast- many times you wont have to brake at all, you will at least minimize braking and save fuel.

Accel hard at peak torque, like a diesel

It might go against what most people “learned”, but it’s a fact. Engines accelerate most efficiently at a certain RPM. That efficiency is what creates the torque peak in the power curve. Old manuals, especially Kawis, show hp/g of fuel graphs, and guess where it peaks? With torque. The best fluid pumping efficiency is also at wide open throttle. Obviously that's better with a manual to avoid “kickdown”. Lastly, the sooner you’re up to speed, the sooner you’re at a low, efficient cruising RPM. It's similar to a "race to idle" in CPUs. That time spent at midrange RPM accelerating is wasted fuel. Source: PhD Engineers & experience

Most efficient manual shifting

Saab did testing years ago and found that most fuel efficient shifting was, (once the engine is at operating temp), to upshift normally to 3rd gear, than rev to slightly above normal 4th gear level, and shift directly into 5th gear. It has worked well for me in many years of driving. Make smooth, deliberate 3rd to 5th shifts, pausing slightly in neutral as you shift.

The 'ol standard-egg driving

A tip from back in the 1970's "fuel crisis" that still is true: try to drive as though there were an egg between your foot and the gas peddle. Easy, don't break that egg and make a mess!

Read the road ahead

Try to keep a "space cushion" around your vehicle. Leaving room between you and the car ahead will enable less braking for traffic signals. Brake usage kills MPG. Avoid cruise control on less than flat terrain. CC will try and maintain speed when ascending/descrending grades. This uses additional fuel Accelerate moderately - while remaining aware of traffic flow. Accelerating into a red - or even a yellow - light used more fuel.

Increasing City MPG with Hyundai Ioniq

When driving in town, accelerate briskly - 3-4 power bars to quickly get up to speed, then let off. This shifts the car into EV mode which can be maintained using light pedal pressure of 1-2 bars on flats and slightly descending surfaces. Keep looking far ahead to start coasting (Regen) when the light turns red. You can actually build your mpg using this technique around town.

Slow down by a few mph on long trips

Try this next time your take a long hwy trip; drive 1-2 mph less than surrounding traffic, and observe that most traffic will pass you by. But because of slower moving vehicles, RV's, semi's, or a nitwit driver who is oblivious to driving with the flow, you'll likely find you'll catch up to all the traffic that passed you by because they had to slow down for the low-speed offender. You'll maintain a steadier speed, gain a few mpg's due to less movement of your right foot (if you're not using CC, which I recommend), have a less stressful drive, and not lose any time to your destination!

Perform maintenance on an older hybrid battery

This tip is very specialized for older hybrids. Performing battery maintenance through charging/deep discharge cycling corrects balance as it restores the cells that have weakened over time. This enables the hybrid system to work more efficiently. It can, in some cases, add over 10% back to fuel economy and it will lengthen battery life as well.

Yes, DO coast in neutral

Tips say injectors shut off when you coast in gear. True on newer vehicles, but the engine braking will waste more power than the minuscule amount it takes to rotate an engine at idle. Coasting in neutral or pulling in the clutch on a bike is the way to go, unless you want to shut the engine off too which is dangerous in emergency situations.

Best fuel consumption during acceleration

This is where bsfc maps for your car come in handy. They show the point of best fuel efficiency during full load. Typically this is between 2000-2500 rpm. So try to give it a good push on the throttle while shifting into higher gear around 2300 rpm till you reach your desired speed. Then get into highest possible gear which gives you a rpm around 1000, cruise and apply all other driving techniques (like feathering)

Check your tire pressure.

Check your tire pressure every two fuel ups or every ten degrees of average temperature change. Did you know that tires are one of the biggest factors of good fuel mileage, braking distance and handling? Did you know that 80% of all vehicles on the road have incorrect tire pressure? Check it. A cheap gauge costs $1 but the peace of mind is priceless.

Average speed

You might think your average speed on a trip is your highway cruising speed, but your true average speed will be much lower. It takes slow-downs, traffic lights, and pit-stops into account. To increase your average speed, simply stop less often (when possible). This is much more fuel-efficient than the same average speed with short jaunts at 75 mph and multiple slow-downs. I am often passed by people two or three times when they stop for food, other traffic, gas, etc.

Feather on downhills

Feather the go-pedal on short descents. You will barely use fuel while adding speed and momentum to the upcoming ascent. You can use an instant mpg gauge to ensure minimum consumption (i.e. 99.9 mpg). This doesn't help much if it's relatively flat out there.

Tip Caution

Some of these tips that users post may save you fuel at the cost of causing more wear and tear to you vehicle that will end up costing more to repair than the fuel it has saved. Example, shutting your car off at stop lights. It will wear out your starter and is hard on the engine in general. Even start stop hybrids have premature engine problems due to shutting off the engine at every stop and they are built for being turned off all the time.

Use Fuelly's "Research Vehicles" before buying a new car

Before buying a new car, consult Fuelly's "Research Vehicles" feature to see what kind of fuel economy current owners are getting in the real world. Do your own due diligence to filter out very obvious outliers, and come to your own conclusions. This info might be more useful to you than an EPA estimated fuel economy number.

Car engine speed at 2200 rpm

Try to keep your engine at 2,200 rpm to get the maximum efficiency. you will get the speed, power and fuel efficiency. Most engine work at max efficiency at 2,200 rpm. Some engine are slightly up and down so try from 2000~2500 rpm and see where are you getting the best fuel mileage.

Fueling Up

Fuel up when the temperature is coldest of the day. Usually right before/as the sun comes up. After the automatic stop, wait 20 seconds (40 if you were close to empty) then you will be able to pump about another 1/4 gallon or more. The time you wait allows the fuel vapors to settle a bit, and the vapors are responsible for automatic shutoff in the pump.

Anticipation

Read the road and traffic conditions not just right in front of you but also further down the road. Being able to anticipate changes in speed lets you lift off and coast rather than waste energy braking.

Drive naked

Take everything out of the car and put it on the driveway. Only put back in what you absolutely need to have for emergencies and this week's chores. Really, you really didn't think I meant take off your clothes, because that would be embarrassing when you got out of the car.
