Increase gas mileage? Efficiency performance!

Hey, yeah I'm sure this post will get a couple laughs because I in fact don't want to go faster!
First off, this is my second car ever. My first was a turbo VW that I did a lot of work to and made it very quick. Now that I'm flat broke and trying to be economical I would like to squeeze ever little bit of MPG out of this car.
So far I get average city/hwy 40MPG. And am very happy with that. But I have heard that I can get these engines up around 50MPG. Is that true? I already drive pretty casualy, keeping it under 3k RPM most of the time. I plan on reducing the over-all weight by removing some interior parts. As well, I plan on removing the AC and perhaps the PS which I know will help.
I'm really just wondering if there's anything specific as far as the fuel system is concerned that I can do to get more MPG. And if there is an exhaust system I can buy that would help as well, even if it is stock. The exhaust on the car when I bought it was: stock headers, then just a straight pipe back to where the muffler used to be (it rusted off at the muffler). It's a bit loud and annoying because of that, especially durring cold starts when it idles high.
This is my first post! Hello, hello, TY, TY, TY very much. I searched for info on this topic w/ no results. Thanks for any help you might afford.

40mpg ?!?! holy shit thats fantastic mpg!

[ShyBoyCA6]

well thats pretty good for a 3g i only get 32mpg and you must have a good carb there to give you 40 but i dont think you can raise it anymore but try pumping shell gas

[pressed001]

So 40 is about it huh? Well, that's pretty good considering.
I do use shell, that's cool. The only gas I liked better they don't have locally is 76. Shell always ran great for me too, but man, that 76, just something about it.

Well... you may be able to get better... the lighter the car is the more performance and mpg u get out of the car... wight reduction is the greatest mod ever and its freeeeeeeeee

[A20A1]

76. I thought I was crazy so I don't mention things like that but yeah, 76 Gas just makes my car and now my moped run smoother.

Welcome to the forum

40 mpgs is really good out of a carbed accord, weight reduction might help though, the less weight your motor has to move the easyer it can get up to speed...

[2ndGenGuy]

You won't get better than 40MPG. There are only two reasons you're getting 40MPG, either you're miscalculating your gas mileage, or you are extremely lucky and have some freak of nature Accord.

[stat1K]

^ agreed, i think it MAY be possible, but i don't think we'd see it out of a carb'd accord. Unless by keeping under 3k you really mean keeping under 2k. I don't see the accord as getting that good of mileage ever. The most i ever got out of my lx-i driving gingerly was 33mpg.

[2oodoor]

my 86 dx (5 sp) was getting 40 avg when I first got it, the silver car not the gold car lx which never got better than 29

[SZfiftyfour]

Oh man, 76 is OLD school lol. I remember when they used to be Unocal, my dad used to run a truckstop for them until they sold-out to T/A (who then laid off all the mgmt). You don't see many 76 stations around anymore.

[Bass Man]

Make the flow of air/exhaust as smooth as possible.

I got 29-32 hwy mpg in my Sedan with a Weber! I also have a really heavy sub box in the back and I had my heavy tool box with me when I got that measurement. I wasn't being anywhere easy on it on the freeway, I wasn't going for milage... Around town I get about 22 or so, though... heh... Damn skinney petal.

We didn't have them for a long time at all. But all our BP stations got switched to 76, so we have quite a few 76 stations out this way. I remember the little antenna balls you would get when you went there before they disappeared the first time.

i got 47mpg with a delta 272, full exhaust, and weber...

[Sh4d0w]

I get 26 in town, and about 30 highway, if I'm light on the pedal - which I'm not.

I remember 76 stations too, specificly putting .32 in the gas tank at one LOL

[w261w261]

I get 47 mpg with power shifts, a/c blowing, 6k shifting, and a little lying.

[Sh4d0w]

... a little lying.

ya pretty much lol

either that or math fail

[itzdave]

no, my carb was hella lean, and my 4dr only had a dash and 2 front seats... no p/s, no a/c.

[SZfiftyfour]

I used to get 30mpg mixed driving in my 2gee with a bad carb and occasional lead foot. Dont remember the tank size, but a couple times I drove it up to PanamaCity beach (approx 320mi @ avg 75mph) with a quarter tank left when I got there. Which is just slightly better then our '06 Scion xA.

We didn't have them for a long time at all. But all our BP stations got switched to 76, so we have quite a few 76 stations out this way. I remember the little antenna balls you would get when you went there before they disappeared the first time.

Thats cool, I wish we had more here. Im all over central fl with my job and can only think of seeing one; in The Villages (a retirement "city" or "mecca" aka "gods waiting room"). I think I still have a bag full of those 76 balls and other Unocal 76 swag in storage.

Yeah... Only the hardest of the hardcore will truly hypermile. And it's usually at the expense of everybody else's gas mileage.

[Bass Man]

Yeah!! I HATE people who take off way too damn slow from stops and use their Cruse Control at 70 in the fast lane... I'm gonna start getting pissed....

[Civic Accord Honda]

my step dad has been setting the cruise control at 55mph since he got a speeding ticket 2 weeks ago.. lol

and BTW it is possible in a accord.... i swear to yall my 82 accord hatch with a very badly adjusted carb got in the 40s-50s.... it would run rich as fuck on start up but when driving it was lean as hell or something....


the best the 4g got was 37mpg with the car completely loaded down with rubermaids and boxs going to ridgecrest from tehachapi (70 miles highway) going 55mph because a cop was behind us the whole time... the average is 30 lol

[MessyHonda]

yeah...i did not pass 30 mpg on my fuel injected car...any weight reduction helps...also take off stuff you dont need like ac and ps...that just creates a drag on the engine.
