• No significant differences exist between the baseline and test MPG for any of the three trucks.
• No significant differences exist for the composite data among all three trucks.
• No significant trends exist regarding fuel efficiency as a function of temperature or duration of study, with the possible exception of the ULSD truck where the slope of the trend-line for MPG vs time (in weeks) was significantly different than zero.
