I drive 12 miles to work. Same route home again.
Workbound journey, typically about 1-2 deg C air temp at 0700 in the morning.
Homebound, about 12-14 deg C at about 1730.
Economy to work: 36-38 mpg
Economy to home 46-50 mpg
This is on days that I'm not driving anywhere during the day, so car sits idle from arrival at work to home time. Same route, same driving style, no significant difference in elevation at each end (neither way is uphill relative to the other), so why the difference?
Both starts are withg a "cold" engine - long enough to cool completely to ambient temp.
Only thing I can see is the air temp.
Does this mean I can look forward to far better economy in summer? And if so why?
