How to Calculate Fuel Consumption

Follow these simple steps to figure out how much gas your car uses

With the price of fuel going up all the time, you’re probably more aware of how much it takes to fill up your car. Knowing your car’s fuel consumption can help maximize your fuel efficiency, but how do you calculate that? Well, you’ve come to the right place! In this article, we’ll tell you how to find your car’s fuel consumption with 2 simple formulas and give you tips on improving your fuel efficiency. Read on to learn more!

[Edit]Things You Should Know

  • Use the formula Distance Driven ÷ Fuel Used to find your car’s fuel consumption.
  • Fill up your car’s gas tank and set your trip odometer to 0. Then, drive your car until your gas tank is empty.
  • Refuel your car, recording the number of gallons or liters it takes to fill up your gas tank and the distance you drove from the trip odometer reading.

[Edit]Steps

[Edit]Finding Fuel Consumption

  1. The formula for fuel consumption is Distance Driven ÷ Fuel Used. A car's fuel consumption is a measure of the miles or kilometers driven per gallon or liter of fuel. If you know the distance you drove and how much fuel fits in your tank, simply divide the distance you drove by the amount of fuel you used to get your miles per gallon, or kilometers per liter.[1]
    Calculate Fuel Consumption Step 1 Version 6.jpg
    • The best time to record your fuel consumption is right after you fill your car with gas.
  2. Fill up your tank to full, then reset your trip odometer. Most cars have a trip odometer that measures the distance you travel on a single trip. To reset it to 0 and measure your distance traveled, just press and hold the small trip button on your car’s dashboard or center console. Set it to 0 when you fill up your car with gas and check it when you need to fill up again—this gives you your distance traveled since you last bought gas.[2]
    Calculate Fuel Consumption Step 2 Version 5.jpg
    • Your trip odometer will say "0 miles" or “0 kilometers.”
    • If you don't have a trip odometer, record the number of miles or kilometers on your car as your "Starting Distance." For example, if your car has 10,000 miles or kilometers on it when you fill your tank, write "10,000."
  3. Drive your car until the gas tank is empty. This calculation works regardless of how much gas is left in the tank. However, the more gas you use, the more accurate your fuel consumption calculation will be.[3]
    Calculate Fuel Consumption Step 3 Version 5.jpg
  4. Refill your tank, recording how much gas it takes to fill up your car. Take your car to the gas station and completely fill up your gas tank. Then, note how many gallons or liters filled your gas tank back up. This is your "Fuel Used."[4]
    Calculate Fuel Consumption Step 4 Version 3.jpg
    • It’s important to refill your tank completely when calculating your fuel consumption. Otherwise, you don't know how much gas your car has used since your last tank.
  5. Record the distance on your trip odometer after you refuel. Once you’ve filled up your car at the gas station, record the miles or kilometers on the trip odometer. This is your "Distance Driven."[5]
    Calculate Fuel Consumption Step 5 Version 2.jpg
    • If you do not have a trip odometer, subtract your "Starting Distance" from your current odometer reading to find out how far you traveled. If your “Starting Distance” was 10,000 and your odometer now says 10,250, subtract 10,000. So, you drove 250 miles or kilometers on that tank of gas.
  6. Divide distance driven by fuel used to get your car's fuel consumption. This tells you how many miles or kilometers you drove per gallon or liter of gas that you used. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallons = 27.9 mpg).[6]
    Calculate Fuel Consumption Step 6 Version 3.jpg
    • If you use kilometers and liters, divide the fuel you used by the kilometers you traveled. Then, multiply the result by 100 to get "liters per 100 kilometers".
    • You have to start with a full tank and fill your gas tank all the way back up to know exactly how much gas your car consumed.
  7. Practice calculating fuel consumption with an example. Terry's odometer reads 23,500 with a full tank of gas. After driving for a few days he needs to buy gas. The odometer reads 23,889, and it takes 12.5 gallons to refill his tank. What is his fuel consumption?
    Calculate Fuel Consumption Step 7 Version 2.jpg
    • Fuel Consumption = (Final Distance - Starting Distance) / Fuel Usage
    • Fuel Consumption = (23,889 mi - 23,500 mi) / 12.5 gallons
    • Fuel Consumption = 389 mi / 12.5 gallons
    • Fuel Consumption = 31.1 mpg

[Edit]Calculating Average Fuel Consumption

  1. Remember that fuel consumption changes based on your driving. For example, stopping and starting the car a lot uses more gas than driving at a constant pace. This is why highway consumption is usually less than city consumption.[7]
    Calculate Fuel Consumption Step 8 Version 2.jpg
    • Using cruise control can help you get better fuel consumption.
    • Fuel consumption gets worse the faster you drive.
    • Since AC burns gasoline, using it diminishes your fuel consumption.[8]
  2. Record multiple tanks of gas in a row to find average fuel consumption. To get a more accurate picture of your car's fuel consumption, gather more data. By driving over a longer period of time and averaging your fuel consumption, you eliminate outliers in your data.
    Calculate Fuel Consumption Step 9 Version 2.jpg
    • Say, for example, that you calculated your fuel consumption on a day that you drove into the mountains, which you don’t normally do. Climbing uphill uses more fuel, so your fuel consumption on that day is lower than it normally is.
  3. Set your trip odometer to 0 with a full tank of gas. After you fill up your car, use your trip button to set your trip odometer to 0. However, don't reset it back to 0 when you get a new tank of gas. When calculating average fuel consumption, you need to know the total distance you drove after refilling your car multiple times.
    Calculate Fuel Consumption Step 10 Version 2.jpg
    • If you don't have an odometer, record how many miles are on your car with a full tank of gas as your “Starting Distance.”
  4. Record how much gas you purchase each time you fill up. To get a more accurate measure of fuel consumption, you need to know how much gas you are using whenever you get more gas. Each time you fill up, write down the number of gallons or liters you purchased.
    Calculate Fuel Consumption Step 11 Version 2.jpg
  5. Drive normally for several weeks. Calculate your average fuel consumption during an average month of driving, as big trips or unusual travel changes your fuel consumption. For a more accurate reading, wait until you’ve filled up your car at least 3-4 times, which is typically over the course of several weeks. Make sure not to reset your trip odometer as you drive.[9]
    Calculate Fuel Consumption Step 12 Version 2.jpg
    • You do not need to fill your car all the way up each time. All you need to do is record the number of gallons or liters you put in your car to calculate fuel consumption.
  6. Fill up your tank fully after driving for several weeks. When you are ready to calculate your fuel consumption, top your car off and record the number of gallons or liters you put in.
    Calculate Fuel Consumption Step 13 Version 2.jpg
  7. Add up the number of gallons or liters of fuel that you bought. This represents the total amount of gas that you used over this period of time.
    Calculate Fuel Consumption Step 14 Version 2.jpg
    • If you filled up 3 times, once using 12 gallons, the other 3 gallons, and the last time using 10 gallons, your total gas usage is 25 gallons.
  8. Divide your total distance driven by total fuel used. Check your trip odometer to see how many miles you traveled from when you began recording your fuel usage. Then, divide the distance you traveled by the fuel you used to get your average fuel consumption. This shows your miles per gallon or kilometers per liter for your test period, which is a good estimate of your car's average fuel consumption.[10]
    Calculate Fuel Consumption Step 15 Version 2.jpg
    • For example, if you used 25 gallons of gas, and drove 500 miles during that time, then your average fuel consumption is 20 miles per gallon (500 miles / 25 gallons = 20 mpg).
  9. Know that your car's advertised mileage is often overestimated. By law, car makers must post the average fuel consumption for cars. However, these are only estimates, and they are frequently on the high end.[11] Your car's fuel consumption is available online at the United State’s Department of Energy website. To find your car's actual miles per gallon or kilometers per liter, you have to calculate it yourself.
    Calculate Fuel Consumption Step 16 Version 2.jpg
    • If your calculation is drastically different from the suggested average, get your car checked out by a mechanic. An engine issue or part malfunction may cause your car to use fuel less efficiently.

[Edit]Maximizing Fuel Efficiency

  1. Use the air conditioner only when you need it. AC is powered by your car’s engine, so AC burns gas when you run it. This means you have less gasoline to drive with when you turn your AC on. When there’s a nice breeze outside, roll down your windows instead of turning on the AC. On really hot days, keep the AC on low or turn it off once your car is cool. This helps make your car more fuel efficient.[12]
    Calculate Fuel Consumption Step 17 Version 2.jpg
    • Running AC on max can decrease your fuel economy by almost 25%.
  2. Drive at the speed limit. The faster you drive your car, the more fuel you consume. This amount you use isn’t small, either—every 5 mph you drive over 50 mph is equal to paying $0.19 more for a gallon of gas.[13]
    Calculate Fuel Consumption Step 18 Version 2.jpg
  3. Drive defensively. It takes more energy to start moving a car than to keep it moving. That means if you are constantly tailgating people, stopping and starting, or trying to pass, you're using far more fuel than if you were keeping an even pace.[14]
    Calculate Fuel Consumption Step 19 Version 2.jpg
    • Leave space between you and other vehicles so you’re able to come safely to a stop in case of an emergency.[15]
    • Brake and accelerate gently instead of slamming on either pedal.[16]
  4. Use cruise control when you’re driving for long, flat stretches. Cruise control keeps your car at a consistent and even speed. This avoids burning up fuel unnecessarily with small accelerations and stops.[17]
    Calculate Fuel Consumption Step 20 Version 2.jpg
  5. Avoid using rooftop cargo carriers. Rooftop cargo carriers greatly reduce your car’s aerodynamics, which slows down your car. Your slower speed means you have to use more fuel to get where you’re going. Instead of using a rooftop carrier, use a towing trailer or load up the inside of your vehicle. These are generally more fuel-efficient options.[18]
    Calculate Fuel Consumption Step 22 Version 2.jpg
  6. Keep your tires well-inflated. If all 4 of your tires are low, your gas usage might lower by 0.3%. Check your tire pressure regularly and put air in them using an air pump. Most gas stations have air pumps for you to use. Then, simply inflate the tires up to the PSI recommended in your owner's manual.[19]
    Calculate Fuel Consumption Step 23 Version 2.jpg
    • Some cars list the proper tire pressure on a sticker on the driver's side door or the glove compartment.
  7. Replace your air filter. This is one of the cheapest and easiest ways to bump up your fuel efficiency. Buy the right filter for your car by bringing the make, model, and year to your local auto shop. An employee will help you find the right filter for your car, as every car needs a different filter.
    Calculate Fuel Consumption Step 24 Version 2.jpg
    • Replacing the air filter on newer cars doesn’t help as much with fuel efficiency. It will, however, make it easier for your car to accelerate without issues.[20]
  8. Turn off your car in traffic. Idling, or leaving your car on when it isn't moving, wastes gas. If you know you’re going to be stuck in the same spot for a while, cut off the engine to save your precious gasoline.[21]
    Calculate Fuel Consumption Step 21 Version 2.jpg

[Edit]Tips

  • Always observe the posted speed limit when you’re driving.
  • It’s a good idea to turn your car off when you know you’ll be stopped for a long period of time (e.g. waiting to pick up someone at the airport). Generally, turning your car off at stop lights isn’t helpful since you’re typically only stopped for no more than 2 minutes.
  • Don't speed up and slow down irregularly. This wastes fuel, especially in big SUV and Sedan type vehicles.

How to Play Euchre

If you’re looking for a classic card game to play with 3 of your friends, it’s time to give Euchre a try. Euchre is one of the most popular card games, and it’s really easy to learn how to play. We’ve got a complete guide on setup, dealing, gameplay, and how to win, so keep reading for all of the rules you’ll need so you can make your game night a blast!

[Edit]Things You Should Know

  • Play Euchre with 4 players split into teams of 2. Use a deck of cards with the aces, kings, queens, jacks, 10s, and 9s of each suit.
  • Rounds last for 5 turns, or “tricks.” Each turn, players place 1 card down on the table. The card with the highest value wins the trick.
  • Score points for your team if you win a majority of the tricks during a round.
  • ​​Win the game if your team is the first to earn 10 points.

[Edit]Steps

[Edit]Objective

  1. Play the highest-valued cards to win tricks each round. During each round, players play 1 card per turn, which is known as a “trick.” After everyone plays their cards, the player that has the card with the highest value wins the trick. Your team gets points at the end of the round based on how many tricks you win, and the first team to 10 points wins.[1]
    Play Euchre Step 1 Version 2.jpg

[Edit]Setup

  1. Split into 2 teams of 2 players. Euchre is only a 4-player game, so choose another player to be on your team. Sit directly across from your partner so the members of the other team are on your left and right.[2]
    Play Euchre Step 2 Version 3.jpg
    • If you’d rather leave it up to chance, have each player draw a random card. The players with the 2 lowest cards become one team and the other players become the second team.
  2. Form a Euchre deck by removing the 2s–8s of every suit. Euchre only uses 24 cards: the aces, kings, queens, jacks, 10s, and 9s of each suit. Set the cards you’re not using aside since you won’t need them while you’re playing the game.[3]
    Play Euchre Step 3 Version 3.jpg
    • You can buy a specialty Euchre deck so you don’t have to pull cards out every time you want to play.
    • Some people play with slightly larger decks that may include the 7s and 8s. They may also include a joker. Ask the people you’re playing with to clarify any rules they use.
  3. Have each player draw a card to pick the first dealer. Shuffle the cards of your thinned-out Euchre deck and have each player draw one card. Whoever has the highest value (with aces being the highest) gets to start the game as the first dealer.[4]
    Play Euchre Step 4 Version 3.jpg
    • Alternatively, you can choose the first dealer based on who had the highest card when you picked teams.

[Edit]Dealing and Bidding

  1. Deal out 5 cards to each player. The dealer passes out cards clockwise around the table starting with the player to their left. Hand each player 2 cards from the top of the deck. Once you go around the table once, then give everyone 3 more cards to fill up their hand. Players can look at the cards in their hand, but shouldn’t show them to their teammates or other players.[5]
    Play Euchre Step 5 Version 3.jpg
    • Alternatively, you can deal out 3 cards to each player the first time around and 2 cards the second time. Either way works as long as everyone gets a total of 5 cards.
  2. Flip the top card of the deck to reveal the potential trump suit. There will only be 4 cards left in the deck after you finish dealing. Take the top card from the deck and reveal it in the center of the table. The suit of the card becomes the potential “trump suit,” which is considered the highest-valued suit for the current round.[6]
    Play Euchre Step 6 Version 3.jpg
  3. Decide if you want to accept the revealed card’s suit as trump. Starting with the person to the left of the dealer, players one at a time decide if they want the revealed suit as trump. Accept the trump if the majority of the cards in your hand match the same suit. Since the trump suit is the most powerful for the round, that means you’re more likely to win. When any player accepts the trump suit, the dealer adds the revealed card to their hand and then discards a card face-down. [7]
    Play Euchre Step 7 Version 3.jpg
    • If a player doesn’t want the suit as trump, they can pass it to the next person to decide instead. If a player accepts the trump suit, an opponent says, “I order it up,” the dealer’s partner says “I assist,” or the dealer says “I take it up.”
    • If you’re the dealer, discard a low-valued card from your hand, like a 9 or 10, since it won’t be as powerful for winning.
  4. Let a player choose the trump suit if everyone passes on the top card. If everyone passes on the trump suit, flip the revealed card face-down again. Starting on the dealer’s left, a player can name the suit they want as trump as long as it’s not the same suit as the card that was revealed. The first person who chooses a trump suit sets it for the rest of the round.[8]
    Play Euchre Step 8 Version 3.jpg
    • If all players still pass without picking a trump suit, collect all of the cards and shuffle them again. The person to the left of the dealer becomes the new dealer.
    • The team that accepts or chooses trump become the “makers” while the other team become the “defenders.”
  5. Choose to “go alone” if you have a hand with a lot of the trump suit. When a player accepts or picks a trump suit, they can choose to “go alone” without their partner’s help if they feel confident in their hand. When a player declares they want to go alone, their partner sets their hand face-down and sits out for the rest of the round.[9]
    Play Euchre Step 9 Version 3.jpg
    • Going alone can get you bonus points if you’re able to win all the hands during a round, but it can be risky if you don’t have strong cards.
  6. Make jacks in the trump and same-colored suit the highest ranked cards. For most suits, the card ranks from highest to lowest are ace, king, queen, jack, 10, and 9. Once a trump suit is picked, the jack of the trump suit becomes the strongest card in the suit and is called the “left bower.” The jack of the suit with the same color (hearts/diamonds or spades/clubs) becomes the second-highest trump card, known as the “right bower.” The other cards in trump rank normally.[10]
    Play Euchre Step 10 Version 3.jpg
    • Example: If the trump suit is diamonds, then the trump suit ranks from highest to lowest are jack (diamonds), jack (hearts), ace (diamonds), king (diamonds), queen (diamonds), 10 (diamonds), and 9 (diamonds).

[Edit]Gameplay

  1. The starting player plays 1 card to lead the first trick. The player to the left of the dealer starts the first turn. Each turn is called a “trick.” The player can choose any card they want to play, and the suit of the card becomes the “lead suit.”[11]
    Play Euchre Step 11 Version 3.jpg
    • Try leading with a card in the trump suit. Other players have to play the same suit if they can, so you’ll flush out all the most powerful cards right at the start of the round.
  2. Play a card of the same suit as the lead card if you’re able to. Take turns clockwise around the table. Players must “follow” by playing a card in the same suit as the lead card. If you don’t have a card in your hand that matches the lead card, then you can play any other card you have in your hand, including a trump card.[12]
    Play Euchre Step 12 Version 2.jpg
    • If you want to win the trick, play a card higher in value than any other cards that have been played.
    • If your teammate already played a high-ranking card in trump or the lead suit, then you can play lower-valued cards since your team is already set to win.
    • If you don’t have any cards matching the lead suit or in the trump suit, try to get rid of a low-valued card. You won’t be able to win the current trick, but you can save your higher-valued cards to win ones in the future.
  3. Win the trick for your team by playing the card with the highest value. Once everyone plays 1 card to the trick, check who put down the highest-ranking card. If any trump cards are showing, then the highest-ranking trump is the winner. Otherwise, the highest card in the lead suit wins. The person with the highest card takes all of the played cards and sets them face-down in a pile in front of them.[13]
    Play Euchre Step 13 Version 3.jpg
    • Example: Trump is clubs. The lead card is an ace (spades). Players follow with queen (spades), king (spades), and queen (hearts). The ace of spades is the highest rank of the lead suit and wins the trick.
    • Example: Trump is hearts. The lead card is king (hearts). Players follow with jack (diamonds), 9 (hearts), and 10 (clubs). Since the jack of diamonds is the right bower, it ranks higher than the king and wins the round.
  4. Continue playing tricks until you run out of cards in your hand. Whoever won the last trick plays the first card to start the next one. Each turn, you’ll only play 1 card. Once you play through 5 turns and run out of cards in your hand, then the round ends.[14]
    Play Euchre Step 14 Version 2.jpg
    • Since there’s such a small number of cards, try to memorize what’s already been played so you can get an idea of what players might still have in their hands.

[Edit]Scoring

  1. Gain points as the makers for winning 3 or more tricks. If your team accepted or chose the trump suit, you gain 1 point if you won 3 or 4 tricks. If you were able to win all 5 tricks for the round, your team gets 2 points.[15]
    Play Euchre Step 15.jpg
    • If a member of the maker team opted to “go alone,” then they get 4 points for winning all 5 tricks instead.
  2. Earn points as the defenders by winning 3 or more tricks. If you prevented the team that accepted or chose the trump suit from getting a majority of the tricks, then they’ve been “euchred” and your team gains 2 points.[16]
    Play Euchre Step 16.jpg

[Edit]Finishing the Game

  1. Pass the role of the dealer and deal out a new hand. The person to the left of the last dealer becomes the new dealer, meaning the role alternates between teams each round. Collect all of the cards from the deck to shuffle and deal out again to start the next round.[17]
    Play Euchre Step 17.jpg
  2. Play hands until a team reaches 10 points and wins. Tally up your scores after each round and add them to your old scores. As soon as a team crosses 10 points, they immediately win the game![18]
    Play Euchre Step 18.jpg
    • If you want a shorter game, only play until you reach 7 points. For a slightly longer game, you could play until a team reaches 15 points instead.
