Fuel Saving Tips


To the guy who suggested taking the bus

Maybe it would be an option if the entire GTA didn't have such godawful public transit. You're better off riding a donkey through mud than using the TTC.

Fill it and then fill it again

When you're filling diesel or gasoline into the tank the fuel will foam up and the pump may think you're full way before but actually are! When you hear the click just raise the dispenser and slowly feed the tank; my car can take another 2-3 liters of diesel after the dispenser clicks and before the tank is completely full!

Finding the right gear in a manual

I drive a 6 speed manual Subaru Outback. I have noticed that at certain speeds it is better to stay down 1 gear then shift to the highest possible. At 40 MPH the car will easily drive in 5th gear but at 25-27 MPG, while in 4th gear I can get around 28-32 mpg. I will then shift into 5th around 45 MPH-ish. This means overall better MPG but you have to be a little more gentle with the gas as pressing it too hard will just significantly drop the mpg. This will not be true for any CVT (and most automatics) based transmission.

Dont Floor it.

when a traffic light turns green, dont automatically push your foot all the way down to the floor, but do it smoothly. flooring it only does 2 things. 1) makes your engine work harder than it has to 2). it wastes more gas.

Use Ethanol free fuel

Gas mixed with ethanol has less fuel efficiency. Energy-rich pure gasoline has a higher energy content so it delivers more power when burned. And because your engine is able to convert the fuel into more kinetic energy, you get to use less fuel but achieve more mileage.

Fill to your tanks capacity +/- 1-2 Gallons

I say this becuase sometimes the auto stop on the pump is wrong and auto stops every five seconds if you know your tank size and know your empty you know a 20 Gallon Tank shouldn't be auto stopping at less than 18 or 19 gallons if you consider you might still have 1-2 gallons in the tank when the guage reads E.

Take the inside

If your on a two lane road with low or zero traffic take the inside lane on curves. This saves time and distance. Every little bit adds up.

Honda Fit/Jazz

When driving on the highway, the sweet spot of the Honda jazz that will give you almost 100km/4l is 85 km/h (53mi/h). Engage cruise control, and let the car go on. It has adaptive cruise control, which means it will accelerate only when necessary, and it is doing so on a linear pattern, which means no hard acceleration.

Vary acceleration by traffic level

Most engines produce maximum efficiency somewhere around 75% power, so when the coast is clear, feel free to get to cruise speed with your pedal most of the way down. However when there is traffic or other potential obstructions ahead, its better to accelerate slowly as even though the engine will be operating less efficiently, braking losses are minimized if there is a slow down.

GPS vs Speedo

Contrary to what has been said here before, differences between GPS and Speedo/Odometer are NOT because of any laws. Since elevation estimates from the GPS are generally 3 times more prone to errors, this also means that GPS speed calculations are affected. You GPS unit has logic that takes its data and "plots" you effectively onto the closest road The bottom line is that GPS indicated speed will always be variable, and subject to small amounts of variable error. Your speedo, OTOH, may be slightly off- however it will be off by a constant ratio. Trust the speedo - NOT the GPS.

Ford Hybrid mileage helper

The first time your engine starts up shift the transmission to low gear for 1 second. This reprograms the computer and uses much less gas while the engine warms up. This makes a big difference on short trips. my mileage went up 15 mpg on the 2 mile trip to the grocery store. I'm averaging 52.5 on my 2013 focus that is not a plug in.

Rolling in Neutral

There are many newer (2000 and up) cars that are run by computer don't actually use fuel when rolling, even in manual cars. Let the car roll while in gear so the computer cuts off the fuel. It'll help you save money and your brakes, since the resistance from your engine and transmission help to slow down your car. Putting the car in neutral forces the engine to keep burning fuel to keep it running. Let off the gas early, let the car roll to slow itself and save your brakes a little bit and save some gas too. Happy driving!

Manual transmission

I have a 5 speed manual Toyota Corolla. Start off in 1st gear, shift into 3rd gear and then shift into 5th gear. Skip 2nd and 4th. My highway and city mileage average is 43 mpg. Shift into neutral and coast on the flats as far as possible.

Be mindful while driving

Think of the accelerator pedal as the speed control for a paper shredder. Except it ain't paper that's going through the shredder, it's your hard-earned dollars. Every time you increase RPM's the shredder speed increases and those dollar bills get eaten faster by the machine. One dollar after another and on and on. I try, within, reasonable and safe bounds to keep my dollar bill shredder running as slowly as possible.

Duff O2 Sensor no Fault light

Don't assume your ecu will latch a fault. My GSF650K9 has a fault code for a faulty O2 sensor. I have had no fault light but some time in the last year the sensor has gone bad. even with the engine dead I got 4.7 volts out of the sensor, with the engine running 4.7 volts. ecu reads that as lean and adds fuel. How long has it been duff?Looking at my drooping economy figures I'm guessing the last 3 months. Did I check the other sensors? You bet.

Coasting alternatives

While most will say to always coast in gear, in most cases this is true. There are times when you will save more fuel if you put in neutral(manual cars). I have a couple stretches of roads where I can coast at the 30 mph mark due to neighborhood roads and if I keep it in gear it slows the car down. I do the surge and coast method of put it in 4th and get it to 30 then take it out of gear and coast. Engine load does go up but due to how long I can coast, it is more cost effective to let the engine hit load and coast for much longer.

Skip shifting

I come at this technique from heavy trucking (where transmissions don't have synchronizers) and it is an "acquired" skill. When on relatively flat ground, it is not necessary to shift all six-gears to drive down the road. In fact,the sooner you get into your highest gear, the better your fuel mileage will be...BUT...you can't lug the engine. So, on my six speed, I shift 1, 3, 5, 6 which allows me to get into overdrive (and every higher gear earlier), yielding higher fuel mileage. Keep RPM's low in every gear and watch your fuel mileage increase...but don't lug the engine!

Downhill alternative

If hill isn't steep enough to downshift to keep speed from climbing, turn on air conditioning - it's worth about 1/2 a gear or downshift 1 gear instead of 2 and activate air. Goal is steady speed downhill without using brakes.

Diesel vs gasoline

When looking for a car, don't be fooled by the higher original sticker price and higher (in some places) price of fuel. almost every single diesel car made for the U.S. market has much higher fuel mileage ratings. We've driven many diesels through the years, and it has surely paid off in fuel savings, as well as they are tougher than gasoline engines.

How to Drive Road Inclines for the Best MPG

Without modern electronics to give you real time MPG feedback, such as my 26y/o Civic, use this MPG driving technique...... When approaching ANY road incline, ascend the grade 5mph slower. Resume your normal speed after the road flattens out or begins to decline. Before doing this you may wish to see if there are no other cars closely behind that might be inconvenienced.

Thinner socks

Wear thinner socks, the weight saving combined with the more sensitive use of your throttle could potentially save 15% of your fuel consumption.

Changing elevations on commute route

Hybrid tip: Try to find the flattest, least hilly commute to work, or if not possible take a route without long inclines to reduce the amount of work done by the ICE on long steady climbs.

Cars behind you? Let them pass!

If you're driving down a small, curvy country road, take note if there's any cars behind you. If they're there for a while, pull over briefly and let them pass. People driving on a challenging road every day might be able to drive it faster than you.

Your cars computer is probably not accurate

In owning three vehicles (2 cars, 1 motorcycle), I have found that the instantaneous fuel economy is not accurate. While you can use this reading to determine driving styles that help maximize fuel economy, the absolute reading itself is probably not accurate. The computer in my 2009 Honda Fit overestimates fuel economy by 10-15%. The computer on my Subaru Forrester overestimates by about 10%. The computer on my Honda CB500 motorcycle underestimates fuel economy by a whopping 20-25%.

Plan your route

Review your commute or directions manually and tweak it to fit your needs! You may be able to simplify, shorten and optimize your route in ways a 3rd party is not aware of simply by seeing the big picture and adapting it to your specific car and driving style. This is especially worthwhile to do for frequently driven routes, you may be able to improve the smoothness, efficiency and safety of your commute with very minor tradeoffs.

Beat he hill, pump first

On driving up any hill, especially rolling hills that have a 30 to 60' elevation rise, pump the accelerator 'before' reaching the base of the hill. This slight speed increase of a few mph increases the momentum of your vehicle during the initial climb of the hill. You'll use less gas overall, regardless of the hill's rise or run. Unfortunately, speed controls are dumb to this tip and pump 'more' gas when the vehicle is rising on the actual hill slope. You'll be surprised at the savings when you look at your instantaneous fuel gauge...

Don't brake

Ok... wait, not exactly, but, the most you apply brakes means wasted energy which used fuel to be produced. So, apply gas only the amount you need to get in traffic, release soon when you prevent you need to slow/stop, and, let the brake to be used when it's completely necessary for safety reasons. Same for older/newer vehicles, automatic/manual transmissions, and neutral/engage coasting.

Drive on concrete roads

Studies show that, assuming optimal road quality and condition, concrete road surfaces are stiffer and have less "play" compared to asphalt when your tires roll over them. As such, the rolling resistance will be lower, yielding a slight improvement in fuel consumption.

Accurate fill-ups (continued)

It also helps if, in addition to Navi's advice, you fill up at the same pump at the same filling station whenever possible. In my experience, every pump's automatic shutoff is at least a little different.

Do not hold on to high gears up inclines/merging roads

It might seem logical to keep it in a higher gear when you accelerate or go up a hill if you want to save fuel, but it lugs your engine and results in you using 100% throttle for a lot longer. In many occasions, it's slightly more efficient to use a short burst of high RPM, full throttle driving, so you can achieve a cruise a lot earlier.
