duh lol. the OG scangauge is HUGE ive heard

 

I believe CC can help, but it is not an absolute rule as many make it seem. If you can hold your foot steady and have the self-restraint to keep from fluctuating, it is more beneficial to not use CC. Whereas if you do not have the ability to hold the pedal steady, then CC might be more useful in terms of MPG.

CC keeps the speed of the car constant. When going up even a slight upgrade while using CC the car uses additional fuel to keep the speed of the car constant (somewhat the equivalent of lead-footing the gas pedal without CC).

In contrast, holding the accelerator at a constant position without the use of CC while increasing elevation slows the car down a bit but does not increase the amount of fuel being injected into the engine. Any loss of speed is gained on the downgrade and as a bonus, you'll get excellent MPG because the speed is increasing and fuel remains constant.

 

do you have a scangauge? if not, please don't tell me what works and what doesn't. btw, you have an automatic, therefore, you lose by default.

 

A scangauge is not going to help you mileage one bit, lets not get things confused. Yes it can show you how being gentle on the gas will increase your mpg, but the gauge is nothing magical. You could get the same benefit by hooking up a cheap manual vacuum gauge, and probably save yourself $140 in the process. Not knocking the SG, I have one myself, but thats not why I got it.

 

I'm not sure if that was directed at me or not, but I do have a scangauge and am in fact in a MT.

 

sorry dude :beer:. i should have quoted the post. i was replying to the member/post above you

 

its all good dude <3. i <3 all fit owners *no homo*

 

Basically, drive like you have an egg between your foot and the gas pedal. That's what I do, and I am averaging over 40 mpg (most of those miles driven on the highway) with my 5-speed Sport, purchased this past April.

Regarding coasting in gear vs. coasting in neutral, I'm not sure which uses less gas. When I coast in neutral, I go a lot farther. When I coast in gear, the car gradually slows down (even on a fairly steep hill) and I end up needing to give the car gas to keep it rolling. So I would wonder which is the more gas-conserving technique. Can somebody with a scan gauge comment?

 

i would hardly say i lose by default by owning an AT Fit, when i'm averaged more than 40 mpg per tank, and more than 45 mpg on the highway.

 

ok guys thanks for all the help. but yall never answered my question

which is

does it hurt your gas mileage to have cruise control engaged while cruising at speeds in which Vtec is open?

 

damn how are all you gettin 40+????? im milking it and gettin 37!!!!!! well we will see what happens when i get my scangauge in!

 

very gentle acceleration, CRUISING at 60, and coasting in-gear whenever possible. also running a SRI, cat-back, and 2-inch drop, which probably boosts mileage at least a little.

 

ah! i know i havent been coasting in gear ( i just read the post on why you should be doing tht yesterday) I will have to try that, well see who that helps... i would like to do a SRI what one do you guys recomend... i know the K&N is crap...

 

i've got a fujita and i'm pretty happy with it. it was $145 shipped, and it's pretty easy to install, too. a lot of people have that weird carbon fiber SRI also, but i can't attest to it's quality or performance specs.

 

I don't know guys, I've always looked at it like this; If I can drive my AT Fit how I want to, and still get 30-33 mpg, I'm happy. Same thing with my bike. There are guys with the same bike who claim to get around 50 mpg, while I usually average 38 mpg riding it how I want to (not too crazy, but I do stretch it's legs on a regular basis). I think 38 mpg from a 700 pound, 1900cc V-twin cruiser ain't too bad!

 

my MT fit is bone stock and i get 45-50mpg on the way to and from work. 10 miles total. 8 freeway/2 city. my city is better than highway. lol. 30mph in 5th gear is anywhere from 50-120mpg. depending on how hard you push the pedal.

 

isnt 30mph in 5th gear bad for the car? lol...putting a big strain on the motor...? i dont know much about gas motors but i know with electrical motors if you dont supply enough voltage you will put a strain on the motor and eventually kill it pretty quick...

wouldnt this be pretty much the same case with our car motors...?

 

if you are trying to be speed ricer and accelerate the shit outta the car, yes. but it doesn't hurt the engine to maintain a speed on a flat road

The problem is related to rpm and the load on the engine rather than speed. Generally speaking the lower rpm limit is about 1500 rpm but that is increased to as much as 2200 rpm with increasing engine effort such as climbing a hill, fighting a headwind, carrying passengers or other loads.

Anytime the engine appears to be 'lugging', that is appearing to vibrate because its straining you should shift down a gear. Lugging is the result of the pistons chattering in the cylinder bores; if you do it enough there be oil escaping past damaged rings and you'll see blue in your exhaust as well as a drop in mpg.

 

This is some good advice....
