No tips you couldn't read on any efficiency page online. Plan your starts and stops well in advance, drive gently (most important around town), use cruise control as much as you can. In the winter, try to drive as much as possible, at least for the first 5 miles, without HVAC on. Shifting into neutral at long lights will save a little, as will not running lights in the daytime. I also try to pull through in parking lots so no reversing necessary. Often this means parking further out, but that also means less distance driven. Keep your tires inflated to 36 PSI in summer and winter. When ICE comes on at slow speeds while accelerating, I tend to accelerate a bit faster as the ICE is just not very efficient until you reach about 38 mph. So I lose a bit on that acceleration, but gain by more time spent at a more efficient speed. Not sure if that last is good advice or not, but can't hurt much, especially if you want cabin heat starting off.
