My baby says made in Japan

 

Actually the Fit's fuel tank is 40 liters. So if you are getting 700km per full tank, you are seeing roughly 41mpg. Which is great, my lifetime FE is just
12.38km/l or 29.11mpg. Granted traffic in and around Tokyo is horrid, the country of Japan looks like ^^^^^^^ without any __________ , with my heavy right foot and the love of a Honda symphony playing several times a day...I'm happy with my overall FE.

 

US Fits are made strictly in Japan. Canada and other countries get the Chinese builds. Likely the next stop for the US is either US or Canada for production.

This sounds more likely. The Fit is rated for 29/33? so getting 40+mpg is Exceptional. Many vehicles that are rated for 40mpg don't get that.

Honda Symphony? with the parts you have on that... you've got a few orchestras playing at once.... ~Jealous~

POAs is basically ethane which is the fastest burning hydrocarbon. Because POAs flow better more oil can be burnt. Its my experience and what I've read.
In 6000 miles I have added about a quart of oil when I used fully synthetic. I am using Honda bulk oil semi-synthetic 5w20 and have no oil consumption at all which is Group II and III oil. I am at 30000 miles on the 4th oil change. I also use premium gas from either BP which has better low end torque with less throttle or Shell which I am currently trying that likes higher rpms with more throttle. They are two different fuels both with different engine reactions. I never though the Fit was slow or lacking power but I never used regular except once or twice at different times. I noticed the mpg drop and that is why I stopped using regular.

 

The car itself will turn to dust before the engine wears out. You can't over rev the engine unless you downshift incorrectly.

And if I'm wrong, simply have the engine rebuilt.

 

Specboy, the MPG ratings changed considerably a few years ago. I routinely get 27 MPG driving highway in my R32, where I'm supposed to only get 23 max based on the EPA.

 

What are you referring to? I'm talking about new vehicles like the Fiesta, Focus (in SFE versions) and cars in the similar class range to the FIT. Most people are getting over the EPA ratings on the FIT but on other vehicles such as the Fiesta (which is rated for high economy), they get lower than the EPA. Some tests have shown it gets worse than the Fit in real world experiences.

Nice presentation.
The best piston speed of most good engines by good engine designers expected to last 200,000 vehicle miles is around the 1800 fpm piston speed. The Fit has a stroke of 89 mm, or 3.5", or 0.29 ft so a revolution of the crankshaft means the piston travels 0.58 ft. So dividing 1800 by .58 yields 3103 rpm. Thus a honda Fit will theoretically last the longest at an average rpm not exceeding 3100 rpm. Thats average, not peak rpm.
The more your average rpm exceed that average the less the life of your Honda Fit engine. Holding long term continuous rpm to 2600 rpm will certainly have the best chance of lasting 155,000 miles, or 250,000 kilometers. Sorry I worked in feet per minute cause the numbers are handy in memory; just realize that 89 mm divided by 25.4 mm/inch and 12 inches per foot is 0.29 ft. and the piston travels up and down per engine revolution.

BTW, 1800 rpm incidently is 60 % of the maximum piston speed allowed by most engine desigers nowdays (3000 fpm) in a quality street driven vehicle expected to last 200,000 miles. The metals available at reasonable prices have raised the old limit of 2500 fpm to 3000.
And 5800 rpm on a Fit with a 89 mm stroke is 3364 fpm. Honda builds a bit better engines than most so 3364 is entirely good for the Fit. That doesn't say run it at 5800 all the time, just occasionally.
And be aware that some manufacturers continue to adhere to the 2500 fpm limit in use for decades in order to save on material costs. Cheaper, less techinically superior, metals are the reason. Honda is not one of the cheapest at allcosts bunch. Thats not accounting for how fast you accelerate; the quicker you accelerate the shorter the life due to hammering on valves etc. Thats a whole new subject.
Cute, eh.

 

Bounce the rev limiter in every gear for increased engine life

 

The best way to get your fit to last forever is simple. Don't drive it.

OP, your worry is almost comical. There are so many variables that go into how long a complicated piece of machinery will last. The thought that what rpm you cruise at on the fwy will have a significant impact on longevity of the car, to me, is ludicrous. If it will make you feel better, don't rev it. Shift into 5th gear at 35 mph, and stay there, regardless of performance. Will it have a significant impact on longevity?

Mine sees extended periods at 5500 rpm (80mph up a 15mi grade). It's got 115k on it, and it's needed nothing. but, that's just a sample of one.

Best of luck!

 

As far as shift points go, if you follow the owners manual it says to shift from 1st to 2nd at 15 mph, 2nd to 3rd at 27 mph, 3rd to 4th at 39 mph, and 4th to 5th at 53 mph. All those shift points wind up being pretty close to 3500 rpms which seems to be a perfect balance of efficiency and power.

 

Or, just drive in first gear all the time.

 

OP, don't even worry about it. Just drive the piss out of it. How can you be sure right now if you'll really even keep the fit that long? Go ahead and baby it if you like. The next owner will really appreciate it!

 

I just realized I'd never thanked you for this great post.

Thank you. Very interesting comment.

 

If you cruise at 2500 rpm, your engine will last longer, than if you cruised at 4000 rpm. Under same load conditions, of course.
Kind of a no brainer to me.
