Mhhh... lets see..

1) Driving technique. Ohhh yes. I was trying to save fuel before I encountered this website by upshifting early, use low rpms, go slow etc. This was OK, but hypermiling techniques (coasting, P&G) gave me another approx. 10% increase in FE.

2) Tire pressure! I go 0,3 bar below max. sidewall pressure. For me, this is the compromise between FE and uneven tire wear. Cannot give FE improvement numbers for this, though.

3) My upper grill block seems to have given me around +5 mpg (48 => 53 mpg on my morning commute), though this is not A-B-A tested, just my trip data.

so long,
