Q. Should I use the same gas station and octane?
A. Yes, Our experience has shown that there is sometimes a difference in fuel economy achieved from one provider to the other. So we recommend using the same fuel and octane rating during the test. Ever notice when you fill up at some gas stations that the area is not level. For testing purposes you should not only use the same gas station but also the same gas pump. Additionally we recommend you top off your gas tank in the early morning hours especially during summer months. During the summer months as temperatures heat up gasoline expands, just like most liquids, providing less energy per gallon.


Q. Are there any other factors that could affect the test?
A. Yes, try to maintain the same driving habits throughout the test, such as speed, etc. Make sure you are not adding or decreasing weight at any point. Also, check your tire pressure. It's important to maintain proper tire pressure. Make sure your O2 Sensor, Down Stream O2 Sensor, and Coolant Sensor are in good condition.
