- 2010 Jetta TDI, red w/Thunderbunny kit
I drive 90 to 100 miles on a typical day. Most of my driving is rural 2 lane road and suburban 4 lane roads. Since buying my 2010 Jetta TDI the average fuel economy for roughly 1800 miles driven has been right about 39.5mpg. That all came to a screeching halt when our temperatures dropped to near ZERO.
For the past two days we've had temps that have been between 2 and 10 degrees (F). Fuel economy on the same roads has dropped to roughly 30 to 32 mpg based on the MFI display. GRANTED there has been some LIGHT snow on the road. And GRANTED snow causes some of the traffic to clog a bit more. But these are the same roads, same travel times, etc that I commute every day.
I can understand losing a few MPG to some snow/traffic conditions. But to drop from 39+mpg down to roughly 31mpg seems unreasonable to attribute to the LIGHT snow conditions.
Thoughts?
