improve gas mileage?


 Share

Recommended Posts

I have heard references on the board of EA81s getting 35 to 40 miles per gallon, mine gets around 25 mpg like that of a normal car, probabaly because of age and stuff, what can I do to boost it? I will be going to college soon and any thing that would help the car save on gas money would be greatly appreciated.:)

 

-AK.

A wise man once said "Believe nothing of what you hear, and only half of what you see" 35-40 MPG, Yeah right! What was the gas mileage figures on the sheet when it was new? Maybe 32. 35 is really stretching it I think but is still possible depending on location, type gas, maintenance on your car, and how many hills you went down with a wind behind you, but 40 MPG, Sorry guys, I like all of you but I am throwing up the BS flag here. Diesel engines get 40 MPG and better. As far as I know, none of us owns a Diesel Subaru. Just trying to keep it real around here. Boz

well to counteract your bs flag..

 

an ea81 hatch gas tank is what 12 gallons? so that would make 1/4 tank 3 gallons right?

 

thankyou

 

now subarubrat can vouch for the distance between my house and another town.. 72 miles one way..

 

my 89' ea81 hatch with 199, 330 miles went there and back on 1/4 tank of gas..

 

so if you do the math thats 144 miles divided by 3 gallons.. and you get what? 48 mpg...

 

now i thought that was insane at first, but the more i drive the car the more i believe it.. i know the guage is right cause when it hits E it sputters and dies cause its empty..

 

so even if you wanted to fudge the number by a gallon (to make up for a quirky gauge) it would still have gotten 36 mpg..

 

 

say its BS whatever, but i do know how well my car runs..

 

next BS story please..

:D

I had a 81 escort that got 40mpg. $40 one way from Northumberland PA to Melbourne Fla. Dam I miss that car! Rolled it drunk on rt 61 in Stonington. That was before DUI's were heavily enforced, so I gotta slap on the wrist w/ an underage drinking citation. I'm glad I grew-up before all the new laws...otherwise I still wouldn't be driving.

The best I ever got out of my 7 year old subaru DL Wagon 5 speed 1800 (a 1981 Subaru that I bought in the year 1988) was 460 something miles to one gas tankful.

I think it averaged out to 35-36 miles to the gallon and involved a lot of freeway driving.

I was actually averaging 30-33 mpg at the time when city driving was thrown in.

 

Now, 16 years later, the car averages 27 miles to the gallon (with the same engine) but I am in the process of upgrading and changing filters, pumps etc and am curious how high I can get it 16 years later.

I made one trip last year from Fairbanks to Valdez.. From the University to the ferry dock in valdez is 400 miles

I made it there with the fuel light on, filled up when I got off the ferry and took 12.7 gallons.. leaving two tenths of a gallon in my car

 

Figures out to 31 to 32 mpg in my EA82

 

I agree with you guys sayin it is possible to get 40 mpg with an EA81 and EA82

Don't let anyone fool you. The technology required to make an internal combustion engine get milage that most can not, will not, and/or refuse to comprehend or consider has been around as long as the internal combustion itself. The more technical gizmos the auto mfg put under your dash and hood, the harder it is to do something about imporving the milage your vehicle will get. If your Sube has a carb (not electronic crap) there is much one can do and people have done to get better milage.

 

Take the so called SUPERCARBS. Call the oil co's or auto mfg and ask them why they do not put them on our cars. If they'd even talk to you, they would tell you that the technology does not work. If so, why do they own all those patents to all those high milage carburation devices?

 

40 mpg should not be that far fetched for a carbed Sube. My 71 Roadrunner got the mid 20's for one summer in the early 80's. That's no light car and I'm sure the sticker for a 383 equippped vehical back then was not near 20mpg. Never saw a sticker on one of them, so don't know what it should have got. I had it as low as 4 mpg with the 440 six pack in it though.

c150l,

Interesting info. I got curious and started searching. All in all interesting, but I did not find any reliable info so far. Do you know of any?

BTW, I found information on some rather curious gadjets, like this one:

http://better-mileage.com/memberadx.html

And a comment on the page is very cute, too:

"Remember to save this page to disk straight away and make a backup copy. This page will change names frequently for security reasons."

I wonder if something like this would kill the engine at once or over some time.

Meeky! You can't trust the fuel gauge for that! If you can, my Legacy gets about 50miles to ZERO gallons, the next ten 10 miles suddenly drink 1/5 of tank...

 

Brim the tank, drive for at least 60 miles, brim the tank again, and use the gas station pump as a measure of how many gallons. This is still not the last word in accuracy, but you cannot trust the dashboard fuel gauge.

Don't you think that if there was a SUPERCARB that got some sort of insane fuel economy we'd be using it. fuel injection is a much better system for fuel economy and performance. there is no carb, there never was or will there ever be one that gets 100 mpg. granted our government, especially the current one, is bowing to the oil companies to give them what they want, and if you were an oil company you wouldn't want new cars to burn less gas.

Ma-Fia, I just read that better mileage page. Sounds like it would work, because the ECU can't tell that it's getting a bogus signal. HOWEVER, I would not fool with the EFI system on my car. Running lean tends to raise combustion chamber temperatures, and who knows what that might lead to..

efi will get you better mileage every time, but swapping in an spfi system is no easy task just for a few mpgs. you can drill some holes in your airbox, and leave that exhaust leake there, as long as its not rigght off the head, your doin better. poor mans exhaust upgrade:D

or give it an open muffler. take out the back seats, and the spare. thats alot of weight.

 

and on the BS. your guys tires were throwing off speedometers, or they are off in the first place. which messed up your calculations. with a gps on the dash, my spfi 2wd wagon got 30 mpg and it was the best ever. and thats a way more effiscient engine than an ea81 carb, so i say BS on 40 mpg.

ok if thats not enough for ya.. if i do all highway driving in this thing, i can go just about 500 miles on a full tank..

 

now back and forth to work i drive about 70-80 miles a day.. multiply that by 5 days.. and you see how far i got on a tank there..

 

by a tank i mean from full to the rim where its pouring out the spout to below the red and i put in right about 12 gallons..

 

so i stand by my mileage :D hmm this might be better than a justy, haha :D
