[QUOTE="Richard L, post: 1016506, member: 52972"] Duane Foster, My comment was to tell zcspec that traffic varies and that probably had the biggest impact on his MPG between his daily commute vs his weekend trip. Many people do not realize that the timing of traffic lights is often different between weekends and week day...even if you are driving against rush hour traffic. Simply catching a few more traffic lights, or if he had to wait at a red light for 30 seconds longer can effect gas mileage more than people realize. It is those slow dow and speed up cycles that eat up your gas mileage. If you use something like a ScanGauge or UltraGauge, you can see that accelerating from a stop light, even slowly will show a drop in gas mileage until you get up to cruising speed....then you come up to another red light and that repeats the slow down speed up cycle. I also wanted to point out that there are errors in the fuel level, and odometer readings. Finally, if one takes a lot of liberty and estimates or rounds off the pump readings, or odometer reading, you can get very inaccurate calculations. ...Rich [/QUOTE]
