I can't get more than 25mpg city driving like an old lady... Highway it goes up to 30mpg but not more than that...

Do you have cruise control? If so, try that. Do you have any mods for your intake? If not, run a snorkel delete and K&N Drop in filter. It's a stock filter replacement and lets your motor breath easier. I get 42 highway without cruise control just running that set up with a little bit of drafting off of friendly traffic.

I get 25-29 with mostly city and I'm a little heavy on the skinny pedal, computer indicated usually settles around 27.3 each time I've reset it. Reset it before a long hwy trip and was over 35mpg but now that I'm home and back to normal city driving it's been dropping back to the 27 range.

I do have the green filter but if I take the cap off it goes even more juicy in the gas so I kept it as stock as possible. I can't even think how much more it will burn with the snorkel delete. Cruise control, yes but don't think will make a huge difference cause I'm actually using neutral as much as possible to avoid the gas pedal :s

Sometimes doing that will actually hurt your mileage in my experience. Cruise control will help, I promise. The snorkel delete will help your engine breath more, as long as you don't get on it too hard everywhere it'll help mileage.

5sp manual, IE tune, k&n drop in, snorkel delete, 16" Conti DWS tires. 90% of my driving is surface streets, within 5 to 8 miles of home, and this area is somewhat hilly--certainly not mountainous, but hardly flat.

I stay within 5 - 7 mph of posted speed limits, but when starting out from traffic lights and then keeping the car in 3rd for well past the green "4th" shift light (that 3rd gear is the sweet spot IMO) gas mileage drops like an anchor. No problem achieving 21-22mpg.

When I shift so that I hit each successively higher gear BEFORE the green light, I can easily hit the EPA rated city mpg.

All this tells me that IF I get an ST, notice I said "if", it is going to be doggone tough to keep my foot out of boost.

In neutral the fuel loop is open. Coasting it is closed. You lose mpg in neutral in the mk3.

In my old 1998 Dodge Neon (stick), whenever the tach was above 1,100 (?) RPM the fuel shut off. Is the logic in the Focus that when it's in neutral the fuel loop is open, or is it geared to the tach (and in neutral [obviously] the tach would be below 1,100.)

But what speeds is that at? I can get 50+MPG if I put in 5th gear at 45mph. We need context.

What was your actual hand calculated mileage after that?

That's cruising at 115kph (@70mph) with cruise control with auto transmission. I use Gas Cubby app to calculate mileage and I get between 5.6L/100Km to 6.0L/100Km (42mpg-39.2). The mileage depends on when I full up, if I fill up early in the week, it is all highway but if I fill up late in the week, its a bit higher due to weekend city driving.
I drive about 200km (125miles) per day for my commute with about 90% of it highway with some stop and go traffic.

I can't get more than about 30 - 31 mpg out of a tank.

My commute is about 25 miles each way, and is 90% highway. I do more city driving during the weekends.

I have a K&N drop in and I did the snorkel delete. I have 18" wheels, though. I think that's bringing the mpg down a bit. I also only have about 5,500 miles on the car.

I also have K&N drop in, snorkel delete, and 18" ST wheels, I also have FSWorks Stealth exhaust.

Most of those miles are from my commute. 100~ mile round trip. Cruise control at 74mph. 5 speed manual.

The car's computer seems to echo the average that Fuelly has come up with as well; about 33mpg. Not bad as the average is over 10mpg better than my previous car's best.

Not sure if Fuelly has been posted in this thread yet, but you can browse other vehicles if you take a peak around the site.

I've seen claims that newer cars do that. I think throttle is significantly reduced, not 100% off/closed. Sure seems the engine is still firing, and it can't do that w/o fuel...

Another factor is that I can glide in neutral for over a half mile on flat ground (if I see the light just changed red - straight country road). The engine uses very little fuel idling compared to racing up to the red light, just to idle there anyhow. If I instead left it in gear, I'd either slow down too early and need to press the gas to get to the red light, or I'd have to drive at speed longer before gliding to the red light (in gear). I often time the light - still am going 30+ MPH when it turns red, and I speed up to make it through before it turns red again. If I instead stayed in gear, I would slow down too much and might not make the green light. Depends on where I am versus the light cycle...
Paying attention like this is how IO always do better than my cars' EPA ratings.

Each size is basically the same overall diameter w/in 2% - the 18" wheel/tire might even be smaller than the 16" and 17" (I am unsure - but you can't assume 18" is taller).

With new OEM tires, I think our MPG readings are slightly lower than reality because we are going farther per RPM of the tire (I am pretty sure the speedo is based on a somewhat worn tire - shorter circumference). I've noticed my GPS reads 1MPH faster than the speedo, which backs up my theory.

Messing around with the air filter, exhaust; etc is much more likely to lower MPG than to improve it. Until those K&N's get dirty, they have larger holes and allow more dirt through them. I had a related issue not too long after I installed one on my last car, so I ditched it and just make sure I change the paper filter fairly often. Not worth a $200+ repair bill and the hassle of cleaning/oiling the thing in my opinion.

I had a Yaris rental car 2 weeks ago which had an instantaneous MPG display. I got around 5MPG more when I drafted - even if it was just a F150 truck, didn't need to be a tractor trailer, and I didn't need to be right on his butt. I wish we had an instantaneous readout.
