Just an update. I calculated 38.6mpg from this last tank of 89 octane. However, this was from a different gas station and I did not drive as conservative, hence, the decrease mpg. I will try and drive conservative on this tank of 87 octane. I might even try FAS. I am still not too sure if this is the best thing to do on my trip of up and down hills. Just thinking that the momentum I loose going down a hill will have to be over come by going up the hill at the previous speed, assuming I want to maintain 60mph up the hill.

 

I was gonna take my car for a spin on the engineway, I mean, motorway the other day...

 

Do you mean roadway, highway, carriageway, tollway, or maybe expressway?

 

My physics professor (B.S. from Georgia Tech GT | About Georgia Tech ) taught that all engines are motors, but not all motors are engines. An engine is just one type of motor. He was probably no where near as smart as you though. What is your degree?

 

DING DING DING finally a man with the right answer one brass ring for your post. But any internal combustion engine is FIRST and primarily an engine when it converts potential energy into usable energy which any motor can not do.

If an internal combustion engine was just mounted on an engine stand with just a flex plate connected to nothing it would just be an engine because you are not doing the whole process with the added step of changing the energy converted into another usable form of energy like it would if there was a transmission or drive system. The drive system connected to the flywheel or flexplate is what is needed to be secondarily a motor to utilize the converted potential energy as mechanical energy.

In other words an internal combustion engine HAS to be an engine FIRST and primarily then when it morphs the output it is also and secondarily a motor. Things can never be a motor primarily and then be an engine... impossibility.. a motor is always a motor it can never be an engine.

So in referring to the JAZZ/FIT motive propulsion system it is an internal combustion engine. Just ask Honda and every other vehicle manufacturer in the world what is the motive power unit in their vehicles and they all agree it's an internal combustion engine.

 

So, If the Fit's engine is an engine and all engines are motors, then the Fit's engine is a motor. And if the Fit's engine is a motor (see logic of the last sentence), then pb and h was correct in referring to his Fit's engine as a motor and you were incorrect to correct him.What about the power sterring motor? You forgot that one on your (incorrect) list of only (electric?) motors on a Fit. I'm also sure that the vast majority of people on this site know the difference between an engine and a starter motor, a fan blower motor, and a power window motor and don't need corrections on semantics.

 

But are hamsters considered to be a motor? Because I'm pretty sure that's what's under my Fit's hood...

 

Not all engines are motors did you miss that part? And motors can never be engines so your logic in relation to the Jazz/Fit is flawed.

It's not semantics it's the nomenclature designed by the manufacturer of the product. And if everyone knows the difference, as you suggest, why continue to use incorrect nomenclature when they know they are wrong WHY do it if they purport to "know the difference"??

O a biggy I forgot one electric motor in my list I humbly apologize for my omission.

 

Nope hamsters would be an example of an engine because they convert the potential energy of eatable fuel into usable form of muscular energy.

 

I think (no I'm sure) my post said Perhaps you need to brush up on your reading skills.

 

Wow what an oxymoron. You are trying to help this forum to be the best Fit/Jazz forum but yet you jump all over somebody for not using a right word, and turn the entire thread about your intelligence. Lame.


BACK ON TOPIC: 10.4:1 compression ratio is actually higher than that of the C32 and the C30 in the NSX which is, I believe, 10.2:1. Use 91, don't be cheap, it DOES make a difference, give it a few tanks, you won't be sorry. For the rest of you who think 87 is fine, well it might be OK to put around town but think about it, what is the lowest octane you find in EU or Japan? 98RON, which is 91AKI. This ENGINE was designed and built in Japan. The only reason Honda says 87 is fine is because if it "required" premium officially nobody would buy it because the American public is completely moronic and they think 20 cents a gallon extra will break them. Obviously, it has knock sensors and will retard timing, but all the people who complain about bad mileage are using 87 octane, you are "low-balling" your engine! It kills me that people are willing to spend so much money on synthetic oil when Honda motor oil is fine, but refuse to spend 20 extra cents to avoid detonation.

Sorry for ranting, flame me all you want, I could care less, this forum is full of childish people that flame everybody for saying anything.

 

baiscally b/c our cars are made in Japan which uses higher octane then it is ok to use higher octane....the only reason why we are using lower grade octane is bc US honda says it only needs the lower grade when it is ok to use higher.

 

Even more lame is claymore's attitude that his/her knowledge is absolute, and must be golden showered on the world - what a crock. See this for more on the great motor/engine debate that is little more level headed: World Wide Words: Engine and Motor
The lamest of all - me actually responding to this.

 

Precisely, don't let anybody tell you higher octane will "hurt" a motor. If that were the case, everybody in the EU and Japan would have blown motors! Your car will run better after a few tanks of 91, once the ECU adjusts! It's a pretty big difference in smoothness, power delivery, overall power as well as fuel mileage. I constantly get high 30s low 40s on occasion mid 40s and i have a sport auto, driving in so cal!

 

From the above link... sounds suspiciously like what I have been saying all along Now that's lame supplying a link that proves the case against what you ARE TRYING TO PROVE. did you even bother to read it? Ha

"The magazine article argues that the difference is that engines contain their own fuel or are part of a highly integrated engine-fuel system, whereas a motor draws on externally supplied energy"

 

Perhaps you should work on you reading comprehension skills. Not ALL engines are motors.

And since we are being specific YOU ALSO forgot to add more MOTORS that are in a Fit. I was being facetious but if you want literal we have to add the very popular wiper motor, two windshield washer pump motorS, and the drive motor in your CD deck.

And you are still avoiding the question WHY do it knowing it is incorrect as evidenced by the manufacturers of the products own use of nomenclature????

 

Perhaps you missed the part where I had stopped posting and your fellow members started the whole thing up again and brought up the subject of intelligence.

Since your ranting maybe you know the answer to the question WHY do it knowing it is incorrect according the the manufacturers of the product???

 

Since we're on the topic of correcting each other's mistakes... it is spelt "you're" in the case of "while you're ranting" as it does not indicate possession, like "your" does,but pity stuff aside... If you read YOUR owners' manual, you will see that it states "87 octane OR HIGHER is recommended", so I ask you, tell me how I am going against the manufacturers' recommendations? As in the case of "Office Space" why use the minimum amount of flair? Flair being octane in this case.. lol

 

Wow it's a biggy one missed spelled word a thousand pardons for my sin. And while we are correcting mistakes you have missed reading YOUR quote in my post showing that I was referring to YOUR post # 51.

I was referring to your use of motor when that is incorrect why do you insist on using a term that is not applicable to the Fit as it has an internal combustion engine for motive power according to Honda and every other vehicle manufacturer and you haven't answered the question WHY? And why all the hostility all we are doing is having a discussion if you don't like the subject no one is forcing you to participate so why be all hostile??
