Fuel Saving Tips
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.

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 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.

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.

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.

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.

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.

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.

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.

07 Highlander 3.3L, on small inclines/grades, highway cruise control will maintain speed at the same RPM (65mph @ ~2050rpm). This will vary base on engine size eg. smaller engines would more quickly increase rpm in response to small inclines.

Ideal MPG speed is definitely 70-80 mph: Nope The only reason you are getting reasonable mileage at 80 mph is because you are ONE car length behind the guy in front of you, that’s it. I see it all the time, don’t try to deny it. Speed vs mpg charts for cars generally show best mpg between 30-45 mph. A semi or RV may achieve best mpg at 55 mph, but don’t expect cars to do the same. Below the ideal speed range you are losing mpg due to reduced engine efficiency, above the ideal speed range, you are losing mpg due to rapidly increasing air drag.

You are approaching a stop sign at the bottom of a hill. In this case it would be better to keep it in gear, cut fuel use to zero, and benefit from engine braking. Shifting to neutral in this situation would only increase fuel use. Approaching stop sign quickly. Keep it in gear, utilize the fuel cut. In this situation, putting it in neutral would not slow you down quickly enough to be the efficient choice, and you will also burn fuel idling the engine. Approaching stop sign slowly. Put it into neutral. By using neutral, you can coast longer, which translates to less acceleration needed to travel the same distance, thus saving fuel.

Air filters affect fuel economy: Only with carburetors For carbureted engines, yes, fuel injected, no. A clogged air filter will affect acceleration, but not fuel economy on fuel injected engines. https://www.fueleconomy.gov/feg/pdfs/Air_Filter_Effects_02_26_2009.pdf

Larger engine not working hard is more efficient than small engine working hard: Wrong If this were true, then things such as cylinder deactivation never would have been conceived, as they would REDUCE efficiency by that “logic”. Engines are efficient at converting FUEL to POWER when they are loaded down. As an example, an idling engine doesn’t use much fuel. Sure, but it also produces VERY LITTLE power. The result is a terrible FUEL to POWER ratio. When you load the engine down by asking it to produce power, it consumes more fuel, sure, but it also produces more power. This time, the FUEL to POWER ratio is much better. Look up bsfc maps.

If you're on a trip, take your time. Travelling at a slower speed will save you fuel AND get you out of many frustrating traffic situations. Rather than getting stuck behind slow traffic, you will be the "slow" traffic :) If you can skip one stop, you'll more than make up the time you've lost from travelling slower. NOTE: If passing, get it over with and clear the lane. You might burn another tablespoon of fuel, but your improved mood will make the remainder of the trip much easier for you as well as others.

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.

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!

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.

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.

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.

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.

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.

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.

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.

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.

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.

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!
