My biggest asset for great mileage: I'm stubborn. If I know the car is capable of more I will push to realize that potential. Good enough, simply isn't.
I have good commuting routes. I have tried all reasonable (and unreasonable - see above) options to find the best. Multi-lane roads with lights instead of stop signs (you can time lights). Reasonable speeds - my highest limit is 55 mph and I never touch that speed.
I know the routes. 32 mph at that mailbox, coast the 1/2 mile to the stop sign around the bend and stop there with no brakes. Adjust to conditions - more drag in winter, rain, breaking in new tires like I am now.
A scangauge is critical. You have to know what's happening and how your efforts are working or not. The use the feedback. Every hill, every slowdown or stop, I'm keeping a mental tally of my recent and long-term "high score". Like this: goal 70 mpg, trip max 65 mpg, last valley 62 mpg. Then the next cycle I aim to at a minimum to match 62, even better to match or top 65, with an eye at 70 the whole time.
Pulse & Glide eoc all the time. EOC is my default mode, while pulse is the special case when I need more momentum.
Minor mods:
engine belly pan that should have been there from the factory
tire pressure
winter grille block
light weight wheels and LRR tires
upgraded rear sway bar - more for fun but it can help keep momentum up in corners
battery charger at night to make up for the loss of alternator during all the eoc
LED lights and eco headlights (45W instead of 55)
