I "hypermiled" a couple years ago when my engine was stock. Only went 100km/h on the highway and drafted trucks some times. I averaged 5.3L/100km

Now I actually have fun when I drive and enjoy it and on summer gas I average 5.8-6.0L/100km
That's aftermarket flow bolt ons

The stuff I remember in addition to drafting are things like never driving over 55 mph, coasting in gear down any hill/grade to take advantage of DFCO, driving as if your car doesn't have brakes, never driving with the AC on, etc.

They lost me at never driving over 55.

I have a Ford Expedition that gets crap mileage under 55, still crap at 55 to 70, and only gets good if going 80 MPH. Interesting what gear ratios and tire sizes will do I guess.

A quick update here:

I just did freeway driving and got 36 MPG no problem. So the fact that I get a measly 22-23 MPG in city is pretty poor (should be north of 27). Seems to me this thing does not know how to idle, sucks way too much gas at idle. Anyone else's experience agree?

Also note: the onboard computer on this is pretty darn accurate (checked it against my own calculation).

I usually average 30-38 mpg mixed depending on how much city or highway I drive. I replaced the spark plugs, pcv valve, air filter, changed transmission fluid and cleaned the MAF. I drive manual and shift at around 2-2.5k and use DFCO at every opportunity.

I have the same experience as you and would be getting much worse mileage if I didn't use hypermiling techniques. I seriously have no idea how some people here can claim 60+ mpg. I'm finding it near impossible to break 40mpg. The only time I think I ever slightly broke 40mpg was during a 400 mile all freeway trip.

I don't recall seeing anyone ever claim 60+ mpg. I've seen extreme hyper miler's get 46-48 mpg, with 50 mpg being somewhat of a holy grail.

I have no patience for these test but you can try 50mph insted of 55 to see if it helps.. 60mpg maybe with 45mph on a long straight with no uphill driving.

I've been averaging 40-42 mpg since purchasing my car 18 month ago. Those are the numbers I get via both manual calculations and using the dash computer average MPG function.

My normal weekly driving is commuting from North Phoenix/Scottsdale suburbs into west Phoenix city every weekday and random errands on the weekend. I normally drive around 250 miles per week. I'm not an aggressive OR hyper-mileage driver. I am a somewhat relaxed (not in a hurry) driver and I do drive smart in the sense that I anticipate whats ahead to let off the gas on upcoming red lights and such, and when I am in slow-moving 'stop and go' work traffic on the highway sections of my route I prefer to leave a good distance between me and driver in front and poke along in 2nd-3rd gear continually, rather than shift/brake up and down and do constant stop/go as the slow moving lull changes here and there. I also rarely exceed 60-65-mph, tend to drive at constant speeds, and usually stay in the rightmost slower lane of the city highways.

If I was to go on a long road trip, I would likely drive around 70-75mph though and use cruise control.

Long road trip highway drives gets me those results with my '07 HB auto :

80km/h = 6L/100km
90km/h = 6.5L/100km
100km/h = 7L/100km

Using cruise control and in fair weather.
