  21. 21. 7/13/2011“Your MPG” feature helpsconsumers calculate, track, andview real-world MPG Calculate and track MPG based on  Fuel purchase records  In-dash readout  B t guess Best Drivers can share their average MPG score  Drivers must register in order to share MPG  Error checking helps improve quality and reliability of data Consumers can view average MPG for vehicles with data 21
  22. 22. 7/13/2011Online “Your MPG” Demonstration 22
  23. 23. 7/13/2011Your Garage is your home base forusing the Your MPG feature. 23
  24. 24. 7/13/2011Your MPG allows you tocalculate and track fuel economy byentering your fuel purchase data. 24
  25. 25. 7/13/2011Gas Tips: Getting the best possiblefuel economy out of your car. Many drivers are unaware that the way they drive and maintain their car can reduce fuel economy by up to 33 percent. Fueleconomy gov provides reliable unbiased tips based on reliable, peer-reviewed studies and input from our panel of automotive experts. Fuel are savings based on current national average fuel prices. Note: If you are already following our fuel-saving tips, you may already be getting the best MPG you can achieve achieve. 25
  26. 26. 7/13/2011 Driving style and conditions have the largest effect on fuel economy. Aggressive driving: 5% 33% 5%–33% Idling: $0.01–$0.03/min. (AC off), $0.02–$0.04/min. (AC on)EExcess weight: 1 2% per 100 i ht 1–2% pounds 26
  27. 27. 7/13/2011Oak Ridge National Lab (ORNL)Currently Studying Speed vs. FuelEconomy Preliminary results from 50 The V6 4WD midsize cars V6 2WD cars, large cars & V6 2WD minivans were current ORNL study 45 combined due to similar results. Data from a major vehicle 40 manufacturer covering 51 g 35 vehicles from various MPG manufacturers 30 Data on 9 vehicles tested at 25 Average for misc. I4 2WD cars (5) NTRC Ave. for V6 2WD midsize cars (7) 20 V6 lg cars, minivans & 4WD midsize cars (9) Data based on laboratory Ave. for V8 2WD large cars (4) 15 tests on a chassis 30 40 50 60 70 80 dynamometer Vehicle Speed (mph) 27
  28. 28. 7/13/2011Speeding can reduce fueleconomy significantly. Speed vs. MPG relationship varies among different vehicles vs On average, light-duty vehicles typically reach optimal fuel efficiency at speeds between 30 mph and 50 mph. F l economy drops about 4 mpg f every 10 mph cruise Fuel d b for h i speed increase above 50 mph Most vehicles examined showed a 3–5 mpg drop per 10 mph increase over 50 mph. i h Four-cylinder cars showed a 6 mpg drop per 10 mph increase over 50 mph. 28
  29. 29. 7/13/2011Vehicle maintenance affects fueleconomy. Out-of-tune engine: 4% Out of tune Under-inflated tires: 0.3% per 1 psi under-inflation of all four tires Wrong motor oil: 1% to 2% Dirty air filter: 2% to 6% for older gasoline vehicles with carbureted engines  DOES NOT reduce MPG for computer-controlled, fuel-injected gasoline engines  We hope to test diesel engines in the near future. 29
  30. 30. 7/13/2011Trip planning and other strategiescan also reduce fuel consumption Trip planning can reduce driving distance and can reduce the mileage under cold-start conditions Drive your most efficient vehicle Stagger work hours to avoid congested rush-hour t ffi t d hh traffic Ride sharing and carpooling Mass transitT l Telecommutingti 30
  31. 31. 7/13/2011Other factors can affect fueleconomy. How much you use electrical accessories Temperature Driving on hilly or mountainous terrain, unpaved roads Using four-wheel drive (Vehicles are not tested in 4WD mode.) New vehicles do not obtain their optimal fuel economy until the engine has broken in. This may take 3–5 thousand miles. Energy content of fuel 31
  32. 32. 7/13/2011All gasoline does not have thesame energy content. EPA ratings based on tests with 100% gasoline gasoline. Using oxygenated fuels or reformulated gasoline (RFG) can cause a small decrease (1–3%) in fuel economy.MMost of the gasoline now sold h a small amount of ethanol f h li ld has ll f h l in it—up to 10% by volume depending upon the region. Using gasoline with 10% ethanol decreases fuel economy by 3–4%. Th energy content of gasoline varies seasonally. T i l The t t f li i ll Typical summer conventional gasoline contains about 1.7% more energy than typical winter conventional gasoline. 32
  33. 33. 7/13/2011Some things that don t improve don’tfuel economy Using a higher grade of gasoline than your vehicle requires requires.  Higher octane merely prevents engine knock. There is no fuel economy benefit. Fuel conditioners, gizmos etc conditioners gizmos, etc.  EPA has evaluated or tested more than 100 alleged gas-saving devices and has not found any product that significantly improves gas mileage. In fact, some such products may damage a cars car s engine or cause substantial increases in exhaust emissions. 33
