1. Higher octane gas(93) will give your car better performance due to the fact it has more cleaning detergent and less debris than lower quality gas, and will give your car improved performance over lower octane (87) gasoline.
2. Dependent Variable: Fuel performance/Efficiency
Independent Variable: Gasoline
Control: Medium octane gasoline (89). Most people usually buy this grade of gas.
3. My experiment relates to my EQ because I'm looking for the best way to achieve maximum performance in an Audi. Quality of gasoline can effects engine performance, so by doing this experiment, I can find which gasoline gives you more efficiency, therefore better performance in a car, or in my case, an Audi.
4.In my experiment, I will conclude which gas gives better fuel efficiency. To do this I will get a graduated cylinder, a quarter gallon of high grade gasoline (93), a quarter gallon of low grade gasoline (87), a quarter gallon of medium grade gasoline (89), and a lawnmower. The gasoline will be bought at the same station to retain consistency and accuracy. Using the graduated cylinder,I'll measure the gasoline out and put it in the lawnmower, which will be turned on and left stationary. Then I'll time how long it takes for the gasoline to burn. This will be conducted for the three types of gasoline. From there I'll record how long the lawnmower was stayed on until it ran out of gas, and from there, I can see which grade of gas lasted more time, and conclude which grade of gasoline is better, if there is.
5. Engineering Research and Development.
If low octane gas is used in a car, then the mpg and performance of the car will not be as good as that of gasoline with a higher octane grade.
