Thanks for the point about the Odyssey...

Where I live it is very flat. But when there is a hill coming, I rev to 2800 approx. to about 95 kph before the hill and l let it come down gradually. Of course, those are small hills...

Last summer, I drove throught the Adirondacks and I had no problem doing this. The only thing is : man that was so long... at 85 kph you feel like you can die from getting old before getting there !

 

Um you know engines arnt build the same as in 1983. The tolerances are tighter, there more efficient, they have different metallurgic properties, and they lubricate themselves better. Plus if honda can design multiple engines that meet or exceed 100hp per liter I think they can make a 1.5L that can run for more than 200,000 miles.

 

Extended trips on the highway at 3,500 rpm is not a concern.

 

there are many s2000's that have 200k miles on their original motors and they have shorter gearing making the rpms at the highway pretty high (close to 5k rpms at 80mph on an AP2, can't remember since I haven't driven my s2000 for awhile). Also, i believe that the majority of them are pushed more than the average fit. because of this, you're worrying too much about it. besides, how much are honda fit motors any ways if they fail?

 

Thanks for the reply.

So 3500 RPM on the highway is OK... What about 3500-4000 shifting in the city? Is it good too ?

 

When i'm on the freeway going 80 mph, my rpms are around 3000. Automatic transmission though.

 

I should have bought AT...

MT is more fun in the city however... But I wonder if it's bad shifting at 4000 RPM all the time.

 

No, Not bad shifting at 4K. The Fit's Redline is over 6K so 2/3 of that is just fine. The fit's power doesn't even really show up until you get up into that range.

Remember, you can save a few pennies by cruising slow but if you stay with traffic, it's safer than hanging in the right lane slower than the rest of traffic. Also, with that slow speed, are you really willing to sacrifice the extra time for a penny or two. Remember, you never get those minutes of your life back

The fit Prefers speeds slower than highway (the manual trans). I used to get 40+mpg on country roads averaging around 45mph. doing that on a highway wouldn't be safe.

Thanks... Well it makes a difference.. I get 49 MPG at 2500 RPM and 33 MPG at 3300 RPM... That's a lot of money on the long run ! ;-)

When you shift at 4000 RPM, is it bad to let the consumption bar rise to the max... I mean : is it better to accelerate slowly or can the engine take it years after years driving more agressively ?

 

I'll chime in with some personal experience. Ive had my MT Fit Sport for about 6 months now, and finally figured out how to shift it properly in lieu of the clutch delay valve. Let it spool up to about 4500 rpm, depress clutch pedal about halfway, quick shift, and ease off clutch pedal. Max mpg sweet spot seems to be in the 3500 rpm range, and motor happily hustles car from that point up to about 6000 rpm. There are a few times where ill accidentally lug the motor, and it makes it known it doesnt like it.
All day driving at 4000 rpm doesnt faze it one bit.

A big reason I went with a Honda is its stellar reliabilty reputation. There are still a lot of older Hondas toling around here in Houston, a city where driving 30 minutes or more to a destination is the norm. More because of stop and go traffic

So let it sing at 3500 or above. It wont let you down.

 

Thanks. Most of the time I feel like I get a comfortable shift from 1 to 2 or 2 to 3 at around 2500 RPM and from 3 to 4 and 4 to 5 at 3000-3500 RPM. I was only wondering if in the long run it would ruin the engine.

 

i'd double-check your numbers, especially if you are going by the computer. I'm one of the high runners for economy with a few tanks that "calculated" out to be around 43mpg but I haven't seen anyone who regularly gets 49mpg on the highway. also, What year fit is it and have you had the computer calibrated (if it's a 2009). before I had mine calibrated, the computer would regularly say 47mpg when I was getting only 42mpg. The lower you go however, the more accurate it was so a 32mpg computer reading was a 30-31mpg calculated tank.

The Few Highway runs I've done have been around 36mpg around 70mph with an abysmal one at 29 due to a cargo box on the roof and a HUGE desire to get home so I averaged 75-80mph.

I have a Fit 2011 MT and at 2400-2500 RPM and 83-84 kph I get between 4.6 and 5 L/100 km which is between 47 and 51 MPG on flat area no use of brake and low wind. My record is 4.4 L/100 km on 150 km. highway. Didn't double check the computer, but it makes sense because I can make over 700 km on a tank (35 liters tank is 5 liters/100 km for 700 km).

So if I drive at 3300 RPM and 6.6 to 7 l/100 km. that is 2 liters per 100 km. more, which, at 1.50$/liters is 3$ more for each 100 km.

So I'm still trying to figure what I'll do !

 

Sounds like you are relying on the Fit's computer. I've found it to run on average about 2mpg high since I had it Recalibrated. I use an app for my Android Phone Called MyCars which I track every fill-up so I always have an Exact calculation of my economy. I'm running about 6.3L/100km. if you have a smartphone, track a half dozen tanks to get a good Idea of your real economy, or get a steno book and just jot down the numbers (Litres, Odometer, Trip).

Hmm... How can it be that precise... I mean : you always full your tank BEFORE it is empty... How can it be more precise if you don't know exactly how much fuel there is left in your tank when you fill-up?

 

Every tank is not exact. There is some "wiggle room" but over time, that "wiggle room" gets smaller and smaller so your overall calculation is more accurate. if you fill the tank up, what you have left is 10.6Gal - the amount you put in. It's not totally accurate but over time it is. I have 124 Fill-ups recorded on my phone and the total number of miles driven/the total number of gallons = my lifetime MPG If I look at only one or two tanks of gas, My stats would be skewed but by looking at many tanks of gas, I can see what My real economy is. what you are looking for is the total number of miles(km) driven divided by the total number of gallons used. That will give you an accurate rating. Chances are, if one calculated tank is high, the next will be on the low side. over 3-4 tanks of gas, it will even out. And even more over time.

The on-board computer is moderately accurate but for a real Idea of your economy, do the calculations.

Exactly, I work for one of Hondas North American drivetrain parts suppliers, we manufacture components to within .003-.015 of a millimeter on average, even for the simple stuff like flanges on the compression fittings of brake and fuel lines.

I can't imagine what the tolerances are on the Japanese made and built Hondas, because I'm betting that it's even tighter

 

Internal specs are just as tight and even closer in some cases, if you've ever had the pleasure to mic it out yourself.

 

The Fit Is Japanese made.

 

Well yeah, but I don't make parts for Japanese Hondas. Hence my comment.

But you do know that a lot of the 2012s are made in China right?
