Long highway trip- how high can mpg's go?!
I fueled up last week the night before a 60 mile highway trip into the city. All but about 15 miles was highway driving. By the end of the trip, my avg readout was a whopping 42.5 mpg. That's like, hybrid territory. I think the only reason I couldn't get it even better is because the trip ended! Who knows how high it would tick. Actually that's my question, how high has your mpg's been on long trips? It DOES top out eventually right? I feel like if I hopped on I-95 for 6 hours with no traffic it would just keep going up! What helps this is if I fuel up before a trip and put no city miles on there. The more highway miles on a fresh reset of the mpg meter, the higher the mpg's go- and the faster it happens. But, what's the highest it CAN go? I really felt like given more road and time, I could have approached 50 mpg- seriously. And my average speed was 65mph, btw.

Well moving all my stuff for college in my fit and taking a 4 hour drive where about half was going up and down hill I got around 38 to 40 mpg. About 210 mile trip. However, I make this trip without my stuff twice a month and I am only achieving 33 to 35 mpg. Don't know why. Maybe it is cause I am driving faster lol

I've just completed 6k miles of driving in five weeks, all up and down the east coast. I've done at least four days of driving without re-setting the mpg display and, if I understand your question, the mpg's displayed shows me the running average of the miles I have driven. It will not go any higher than that.
Along the way, say if I have a 12mile down hill run, it will peak out at some strangely high value for that occurrence, but as I continue on it will settle down to display the average for the total miles driven since the last re-set.
As I compare the on-board to actual computed mpg I'm most always within 1-2mpg, as long as I don't figure it after one of those long down-hill runs - that skews the on-board numbers.
On nice turnpike runs it's just about dead on.
BTW I'm averaging 38mpg overall

The best I've got was 44 mpg. I was driving 60-65 mph on the highway Thanksgiving night for about 100 miles. It was pouring rain really hard and I couldn't see so that's why I was at or under the speed limit.
On the same stretch normal driving 70-75 mph I see 37 mpg.

if you really want to pile up the MPGs, drive 45 miles per hour on cruise control down the interstate. lol.
my drive home from work is on a relatively quiet county rd. i used to do 50 mph on it... but now i do 45 mph, and my MPG ticks up quite quickly.

It depends on speed, terrain, and changes in speed. Driving to/from the Sacramento area, with some elevation changes a couple of low mountain passes) and at least one or two Cali traffic snarls, I usually do 37-39. Without any stop-n-go traffic, it's closer to 42-43. On completely flat land, at a steady 60-65, with no A/C, I've gotten ~50.

You'll always get superb economy numbers right after a fillup/reset, but that will drop as the computer averages out the whole tank.
I did a road trip early in September and tried to keep my speed at around 70mph and the average for the 5000 mile trip was about 38mpg.
Trip was from Upstate Noo Yawk out to Utah and back in about 9 days.

How many of these numbers are from cars that have had the mileage TSB fix? I haven't done it yet, but have read that our computers give a 10-15% HIGHER reading than what you are really getting.
That being said, with mine (non TSBed) I have gotten 70mpg after filling up in Tahoe, and going down the mountain to the foothills. I was super stoked! But, as has been said, it evens out after normal driving resumes.
My average commute gives me around 39/40mpg. Again, this is probably high due to the computer. Real world, I get about 34/35mpg

I took a crappy cell phone picture when my average mpg indicator clicked to 50 mpg. But, it was short lived as I was at the end of a trip and started city driving.
We drove roughly 240 flat freewa miles and 90 hill miles (45 uphill and 45 downhill).
Also, this was before I got my mpg indicator adjusted for the 10-15% variance.
I was pretty excited even if I knew it was a little overstated. :-D

Normally I would be so jealous of everyone getting higher MPGs than me but at this point I am just thankful I can get over 30. Before this Fit I had a Honda Pilot (2004). Don't get me wrong it was super nice, completely loaded, but I got 16 mpg on a 20 gallon tank. Before that I had a 2 Door Tahoe (95'). I got AT BEST 10 MPG! It was the 5.7 Liter V8 350 motor with flowmaster exhausts. And that was a 30 gallon tank! So I would manage to get maybe around 290 miles on one 30 gallon tank in that vs my fit where I get around 350 on a 10 gallon tank!

Here's what I've discovered for my situation. I can get 40 on the highway just falling out of bed. I've gotten as high as 44+ but it takes patience and driving at speed of low 60s or lower.
Because I live in area with rural roads where I can often drive at 45 mph with few stops, I can average around 37-38 for driving ratio of 50/50 town/highway. But because I drive more highway miles, my actual average is almost 40 mpg. Yes, almost 40 mpg average! That's real world. I keep track of every fill up in gallons and average it over total miles so no skewing from tank to tank. I doubt I'd do much better with a hybrid with the type of driving I do. I am quite pleased with these results.

That was 120 mile round trip I was talking about and by the end of that tank of gas, I averaged 34 mpg. It dropped back down as I expected because for the rest of the tank it was suburban driving. Since then, my mpg's are taking somewhat of a hit because of the colder temps now. This current tank I'm struggling to stay at 30 mpg's, averaging 29.5 at the half tank mark. And none of these miles are highway at all. The Fit just absolutely loves highway driving. The mpg's always tick up and up. But 30 mpg's city [suburbs] isn't bad at all either. But as it gets even colder and then throw in snow/ice conditions, and it will be even tougher to get the higher mpg's that spoil me in the summer. And of course, the price of gas has ballooned too. A year or so ago we were screaming over these prices. And when it drops back down to 2.60 or so, we'll think we're getting a bargan. All part of the plan to keep us firmly by the balls. We're so screwed. At least we get good gas mileage in these Fits. But still...so screwed we are.

A few months back I took a road trip to the midwest taking the northern route to Kansas City and came back taking the southern route (about 3200 miles). IIRC I averaged mid-low 40s in MPG. This is without the reprogramed MPG indicator.
Oh BTW....people living in california are sooo screwed! Gas averages at least $.50 less everywhere else
