AKIRA Posted January 21, 2004 Share Posted January 21, 2004 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. Quote Link to comment Share on other sites More sharing options...
MaroonDuneDoom Posted January 21, 2004 Share Posted January 21, 2004 i save alot of gas by babying it and not floring it too often. also, while cruising, i shift up in order to lower RPM. kind of obvious but it works better than you would think. just my spare change Quote Link to comment Share on other sites More sharing options...
Partsman Posted January 21, 2004 Share Posted January 21, 2004 Keep your maintenance current. Old spark plugs, wires, and having the timing off will suck the gas. And, like MaroonDuneDoom says, baby it! Quote Link to comment Share on other sites More sharing options...
subiemech85 Posted January 21, 2004 Share Posted January 21, 2004 stiff throttle spring made mine for the toy with a super light pedal from 1/2 of a rear drum brake return spring Quote Link to comment Share on other sites More sharing options...
AKIRA Posted January 21, 2004 Author Share Posted January 21, 2004 ok, I will try to floor it less often:( i'll check the timing too. and fix the leak in the exhaust manifold (saps power right?) and get new plugs. clean some stuff also.

PHATBRAT Posted January 21, 2004 Share Posted January 21, 2004 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.

Meeky Moose Posted January 21, 2004 Share Posted January 21, 2004 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..

Stupidru Posted January 21, 2004 Share Posted January 21, 2004 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. Quote Link to comment Share on other sites More sharing options...

Boz (Anyone that wants to challenge this needs to show me proof) 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.

torxxx Posted January 21, 2004 Share Posted January 21, 2004 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 Quote Link to comment Share on other sites More sharing options...
northguy Posted January 21, 2004 Share Posted January 21, 2004 On my trip up the Alcan, I kept my 83 Brat at a constant 55 mph. Time stunk, but I loved the 30+mpg I got through Canada. Around here, the 65+mph drops it down to mid to low 20's. FWIW. Quote Link to comment Share on other sites More sharing options...
c150L Posted January 22, 2004 Share Posted January 22, 2004 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.

torxxx Posted January 22, 2004 Share Posted January 22, 2004 as soon as I get all the emissions stuff ripped off my ea82 carb.. I will do a mpg test and post the findings Quote Link to comment Share on other sites More sharing options...
Ma-fia Posted January 22, 2004 Share Posted January 22, 2004 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.

Setright Posted January 22, 2004 Share Posted January 22, 2004 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. Quote Link to comment Share on other sites More sharing options...
WJM Posted January 22, 2004 Share Posted January 22, 2004 I got a steady 28~29 mpg on my GL-10....until my RX blew the HGs agian and i started driving it like it was a rally car... Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted January 22, 2004 Share Posted January 22, 2004 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.

Setright Posted January 22, 2004 Share Posted January 22, 2004 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..

archemitis Posted January 22, 2004 Share Posted January 22, 2004 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.

iluvdrt Posted January 22, 2004 Share Posted January 22, 2004 my 87 gl10 got about 31 on my last trip to ohio, and that was going through the mountains in WV. my ford probe 2.0 gets about 53mpg on the highway. ill drive from jacksonville, nc to daytona beach on one tank of gas. it has a 12 gallon tank. sorry thats 48.3 mpg. its 579 mi to daytona beach from my town.
