Also worth noting is that Google maps now offers an option to find the most fuel efficient route. So if you're not in a hurry (plan ahead) then it will help you avoid hills and stuff like that.
The tire pressure thing never made a noticeable difference for me, but I'd be interested to hear what others have found.
It does make a difference when cruising for hours, on the highway. But in the city, or if your commute is less than an hour, it’s all the same. That’s my personal experience, atleast.
That's a good point. Speed is likely a factor.
