An attempt at MAX MPG > miles per gallon 1999 Gs-R Integra
*** Read this post, then see my update on page 3!***
EDIT: Just for clarification, make sure to read ALL of my posts in this topic so you aren't mislead by the parent topic.
EDIT 2: I need to also add that my car is vastly different from most of the vehicles on here, so a +/- ~10% margin of error in my results is in order.
First, a little background. The Gs-R Integra is rated to get upwards of 32 mpg (highway). It's gas tank is 13 GALLONS with the fuel light coming on at around 10 gallons of use (2 gallons left).
Seeing as I usually get around 235-265 miles per fillup (on 10 gallons) >> let's just say I get about 23-26 MPG just farting around. I'm a VTEC nut...which means I have never used 5th gear in my life, and don't shift from 3rd to 4th until about 85mph.
I decided to see what I could do in trying to achieve a maximum amount of MPG. This whole process basically involved filling up the tank one day and then driving safely while utilizing fuel efficiency techniques like shifting from 1st-5th (not using 2nd, 3rd, or 4th...but I didn't need to, and I never used additional throttle), and utilizing that miracle of Honda technology called Cruise Control. I also frequently coasted. I NEVER went over 4000rpm, that means NO VTEC this entire "testing" time. Mind you all of this is being "tested" whilst I commute to a city right outside Washington, DC (College Park) for class. This is typical city beltway traffic which ranges from cruising to stop and go.
The results speak for themselves:
[At the Gas station upon completion of my test]
[Hitting Vtec for the first time in ~350 miles, PRICELESS]
[The trip home, consisting of cruise control set to 72mph]
***Please pardon these pictures, they were taken with my Nokia 3650 camera phone, and not the usual Canon G5 5megapixel goodness. Also of note is my CEL - it is because of a Japanese Cat, and does not effect performance numbers.
Clearly the results speak for themselves, as I averaged a bit better MPG (and all of this in light of my modifications). This was a 400 mile tank full!
Additional impressions:
I can honestly say this was a fun experiment. It was a change in my style of driving, and it certainly added to me taking only a couple more minutes to arrive at my destinations. The lowered stress from "mindless" cruising and sticking in the right lane of the highway was a neat benefit. I would encourage everyone to try this once, and stick with it until the end of the tank. If anything do it for the couple of bucks you save.

Re: An attempt at MAX MPG > miles per gallon 1999 Gs-R Integra (Tweakmeister)
I average is 300-325 miles per tank, and I don't do anything special. My best was 400 miles on a tank.
If this is all city driving, then yes that is damn good. Mine is 95% highway so that may make a difference.
Also, shifting from 1st to 5th isn't the optimal technique. It's not just engine rpm, it's the amount of fuel being dumped in. Shifting from 1st to 5th would bring your rpm's in 5th really low, and the engine is going to have to use quite a bit more fuel to develop any power at that low an rpm. I would guess if you shift below 3000rpm in every gear you could do even better.
Nice job, it's good to see not everyone isn't concerned with how fast they go, but how efficiently they can get there.
Cheers,
Sean

Sean,
Appreciate the input. I guess I could say I could hit 300 per tank without too much effort if I ran it down to the drops.
With my shifting technique, you make a great point, but I should clarify I wasn't stomping the gas pedal when in 5th, simply letting the car "coast" up to speed without additional throttle.

Man, 3500 RPM at 72 Mph, I am at 2900 at 70 mph in my RS. BTW I have OEM wheels and tires on so gearing a little longer, but that much of a difference between RS and GSR.

That's some great input! Goes to show what tuning does for you (as I'm not tuned and running increased fuel pressure).

Re: An attempt at MAX MPG > miles per gallon 1999 Gs-R Integra (Tweakmeister)
I hope kids don't learn from this post. First of all, the Integra isn't rated at 32-35 highway. it is rated at 30mpg highway using 91 Octane gasoline. And then the part about only using 3rd and 4th on highway is just plain dumb (Note: not cool). It hurts the engine badly to keep the car at high rpm at all time. Then shifting from 1st straight to 5th = save gas is another stupid saying. Once the engine gets to the high rpm range, it'll use up a lot of gas. And then the resulting of 30mpg=good result is just a joke. I get 32mpg whenever I drive long trip just driving normally.
The proper way of saving gas is not to step on the gas pedal too deep. Shift at low rpm. Stay under the VTEC switch rpm.

We are actually both wrong as the GS-R is rated at 25/31.

i once filled up and cruised at 70 MPH and got 150 miles on the first 1/4 tank. but of course, the further down the tank you go, the faster the gas goes, at least in my car. and it's only on the highways. city driving, i get about 250 on average.

Another observation I made - the last half tank went in ~150 miles versus the first taking about ~200 miles.

30mpg is for 2001 GSR.
http://www.acura.com/preowned/...ar=01
31mpg is for all previous years....

Intereting how I didn't know earlier GSR gets better gas mileage.

Re: An attempt at MAX MPG > miles per gallon 1999 Gs-R Integra (Tweakmeister)
I drive a lot of highway and the most I ever got was 35.02MPG on my '01 stock GSR. On another occasion, it was 33.89MPG. On average with some city driving, I'll get anywhere from 28-32MPG. Strictly city driving, I'll be around 25-26 averaging about 300 miles to a tankful.
My figures are really precise since I top off my tank to the brim every time to calculate my fuel consumption accurately. On the GSR, once the pump goes "click" you can still get about 2.2 more gallons in the tank. Once the pump clicks, the pump I use at my local station can be modulated to flow fuel very slow so after a minute or so, I'll see the gas come up to the filler neck and stay there. It's then absolutely full. Heck, that's another 50 miles more range just in case. I hear stories about it not being good to top off your tank but I don't buy it. I've been topping off my tank for over 20 years in all the cars I owned/own (86 Integra, 96 Accord, 01 GSR, 91 NSX) with no problems at all.
If the GSR had a sixth gear (with the rest of the gearing unchanged) as a crusing gear, I'm sure it would get even better mileage.

To some more interesting info to add to the mix.
Could this be from more strict emissions equipment perhaps? (I know it sounds strange). Or weight?

I had a similiar experience with my Integra. I usually fill my tank when it hits 1/4 tank left, but before I went to the track, I drove it until the Gas light came on.
I put exactly 10 gallons of gas in it, and off I went.
I drove all the way to the track, ran the car 13 times, and drove all the way home.
On my way home, the gas light came on, and I had driven 275 miles!
This is on a turbo b18b, with 310 cc injectors.

This is totally normal. It happens to every Honda. The gauge we have is not 100% accurate. When you fill up your tank, the needle should jump way over the "F" mark.... unless your fuel sensor is not working correctly (like mine, which is a really common Integra problem).
The other thing you might want to know is the low fuel light. When it starts coming on and off, you probably still have about 2 gallon of gas in there, but your needle is probably pointing very close to "E" already. It is a way to prevent people from running out of gas. It is pretty hard to use up the whole tank of gas since none of us who let that low fuel light stay on for too long before filling up gas.

Re: (RedGSR)
i agree, the left half of the fuel gauge goes down faster then the right half. My best MPG was around 350miles on a stock OBD2a computer, then with hondata and a base map it sunk to 300miles.
Either way, i don't see how some people could only manage to get around 200miles to the tank, something must be really wrong with your car or you must not have done regualr maitenance on it at all. The hondata program DUMPS fuel into my engine and i still get decent mileage
*edit, i like planning with the fuel light while i drive, see how many times it could go on and off before I know i <U>really</U> need to get gas. does this damage the pump? or could the OEM pump take this fine?

Why do you like counting the fuel light going on and off??? when you make quick turns it will make it go on and off, depending on which way you turn.... same for going uphill and downhill...
About the fuel pump, it is best to keep a decent level of gas in your gas tank at all time. It would extend the life of your fuel pump... but then, it isn't all that hard to replace the fuel pump.

Re: (RedGSR)
James!!!
Keep your ******* right foot off the gas and you will save lots of $$$
I get 270 miles per 10 gallons city
I get 320 miles per 10 gallons highway
This is everytime too!!!
Also gas looks expensive in Edgewater...come to Millersville where the gas is cheap and 97 is so near

Re: (arizsun21)
I maxed out with 300miles WITH fuel injector cleaner. I ran that down to nothing.
I filled up..now I got 240 miles!!! WTF! Keep in mind, this was all HIGHWAY driving, at 70mph. I travel alot, and often. Any ideas on WTF is wrong? My car is VERY well maintained! During this time, it was not redlined, or vtec(e)d.
I normally dont put it in vtec either, cause im poor college student, I cant afford to **** money away anymore. Please help!
