Increasing Gas Mileage

Introduction

With increasing gas prices and the lack of alternate fuels the mileage per gallon of a vehicle has become a concern to many drivers and consumers. The focus of this experiment is to discover which factors affect the gas mileage of a vehicle by adjusting three driving settings. The experiment will be performed on a 2009 Honda Civic, but the targeted population is vehicles of any make and model since the results can be extended to all car models since all vehicles use the same basic functioning principles. The experiment tests three driving settings. The car's A/C temperature and tire pressure are two settings which can be readily adjusted by the driver at any moment before driving (Newman, 2010). The tire pressure cannot be controlled during the trip, but it will stay steady for a short trip. The third setting cannot be controlled at the flip of a switch like the A/C, but one can avoid high traffic zones knowing during what time intervals they occur, of course it is not always possible to drive through the ideal light traffic zone.

Problem Statement

Increasing gas prices and the lack of alternate fuels have made the mileage per gallon of a vehicle a primary concern to many consumers. The goal of this experiment is to determine which factors affect the amount of miles a vehicle travels per gallon by adjusting different driving settings (Montgomery, 2008).

Organization And Mechanics

First a fall you need to fill up your vehicle's gas tank to the fullest. Then filling up the tank, you need to set your car's trip odometer to the zero. Then once you drive the 100 miles, then you need to refill your tank again. You then need to write the number of gallons required to fill your car again and the amount of cost that you had to bear. After this you need to have a record of the mileage on the trip odometer.

Finally you need to measure the number of miles driven by the car and then divide it by the number of gallons that it took you for those miles driven. This process will enable you to reach the mileage of your cars gas in miles per gallon (Marinucci, 2012)

Gas Mileage

Generally it's been inferred that the slower you drive the better would be the mileage that you will be getting from it. To conduct experiments try driving your car at a steady speed. For instance drive your cat at a speed of 30 mph and 40mph. This sort of speed would allow you meet the road limits with ease and to carefully track the gas mileage of your vehicle. The ability to monitor gas mileage can show you the effects ...
