mtsfabman Posted March 16, 2004 Share Posted March 16, 2004 Hello all, I was curious what kind of gas mileage you all are getting with various models. I have an '84 EA81 wagon with a weber and 27" tires. After correcting for the tire size on the odometer, I'm only getting 19-20mpg. Is this average???? I was wondering if I could get some input from others that have EA81 with stock carb, EA81 with webber, EA81 turbos, EA82 with carb, and EA82 with FI. Also mention your tire diameter so we can see apples for apples. Thanks, mtsfabman Quote Link to comment Share on other sites More sharing options...
drewcifer85710 Posted March 16, 2004 Share Posted March 16, 2004 I get roughly 200-220 miles to a tank (realistically around 13 gal when i fuel up) with my 86 EA82T. Tires are stock at 185/70/13. Mileage improves a bit if I keep my right foot out of the radiator, but that wouldn't be any fun. Quote Link to comment Share on other sites More sharing options...
Snowman Posted March 16, 2004 Share Posted March 16, 2004 Best I've heard of was my parents' carbed 87 4wd 5 speed wagon getting over 40 mpg on the highway when it was pretty young. Worst I've experienced was about 200 miles to a tank (13.3mpg), which has happened several times when my 86 carbed 4wd 5 speed wagon has been severely ill in some form. Most of the time, she gets mid-twenties on the highway. The most satisfying fuel economy was on a run we made last summer in my car, in which we ran at 85-90 mph to the next "major city" to go see a movie. The trip that normally takes five hours took three hours and twenty minutes. We later figured out that we were getting around 18 mpg, which normally isn't all that impressive but is quite awesome considering that's basically the top speed of the car.

TomRhere Posted March 16, 2004 Share Posted March 16, 2004 Last road trip in the '82, I got 31mpg, w/stock tire size. This was combined driving on State 2-lanes and the big 4-lane, 60-75mph driving speeds. Edited to correct typoes. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 16, 2004 Share Posted March 16, 2004 In my wagon (84 EA81) when it was 2WD and a BRAND NEW Weber, I got 32 MPG on a 600 mile trip to WCSS5. Now same car, no engine changes at all - same new Weber, with 28" mudders, and 4WD, I got 16 MPG on a 300 mile trip I made week before last.... Bugaru got 16 MPG in his hatch on the same trip which weighs less, and has smaller 27" tires - but he's got the Hitachi, and crappy gearing, so I still did better. I think our calculations were pretty accurate - we filled up at the same places each time, and checked how much gas we put in, etc....

Snowman Posted March 16, 2004 Share Posted March 16, 2004 Wow, cutting your fuel economy in half! I would wonder if something else hasn't changed. I remember Subarujunkie mentioning some time ago that he got 26 mpg on the highway with his lifted wagon with hitachi. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 16, 2004 Share Posted March 16, 2004 You can figure it out yourself if you like... I get 200 miles to a tank (maybe 210 - the last time I almost ran out it was 207 and it died on the way into the station).... My tires account for a 19.2% difference in speedo, and odometer readings (175/70R13's to 215/75R15's)... 210 * 1.192 = 250.32 actual miles driven. My tank capacity is listed as 14.5 gallons... 250.32 / 14.5 = 17.26 MPG That's figured at 210 miles, and like I said, I nearly ran out at 207 last time I tried that, so I would imagine that this calculation is pretty accurate since I doubt the fuel system is capable of completely draining the tank of every last drop..... And for comparison, I could go over 400 miles when it was 2WD with no trouble at all. I seriously doubt anything has changed - except of course the obvious stuff - and there's plenty of people around on the board that can tell you how good my engine runs.... it's top notch.

86subaru Posted March 16, 2004 Share Posted March 16, 2004 i get 22 in my turbo full time fwd a/t wagon , but did alot of mods , thats in the city Quote Link to comment Share on other sites More sharing options...
jmr052 Posted March 16, 2004 Share Posted March 16, 2004 21 is pretty consistent. I drive mostly highway at about 80mph. I am running on 195/60/15 tires. The mpg has been corrected for the tires. Although with the new engine it looks like the mpg will improve. Jay Denver, Co Quote Link to comment Share on other sites More sharing options...
archemitis Posted March 16, 2004 Share Posted March 16, 2004 spfi 2x got 30 mpg fully loaded, with 5 people and luggage, for 1000 miles from texas to mn. im hoping my fuel injected hatch can get close to 35+. Quote Link to comment Share on other sites More sharing options...
Meeky Moose Posted March 16, 2004 Share Posted March 16, 2004 the lifted hatch would go about 160-180 miles on a tank.. thats not figureing in the difference in tire size.. see signature for what it is.. my RX will go 140-170 on a tank of gas... the spfi wagon will go 250 on a tank.. (damn slippin auto trans) the stock 89' ea81 hatch will go 317 miles on 8.5 gallons of gas.. this is the commuter car Quote Link to comment Share on other sites More sharing options...
Dennis ex24 Posted March 16, 2004 Share Posted March 16, 2004 the XT (bigger turbo, modded MAF, IC and more) gets about 13MPG running around the city and some highway miles. the Imp.

wagonpowaa Posted March 16, 2004 Share Posted March 16, 2004 anywhere from 21-30 mpg depending on what kind of driving I'm doing. 320 miles drafting my friend in his Suburban=35mpg, but usually 23-24 Quote Link to comment Share on other sites More sharing options...

At the moment she isnt doing quite so well, as she has developed a major exhuast leak right at the exhuast manifold - will be getting fixed on friday...

My dad drives a little more conservitive in his WRX and he gets 24 or better. Quote Link to comment Share on other sites More sharing options...
dave valiant Posted March 17, 2004 Share Posted March 17, 2004 I get 20-22 MPG in my Turbo Brat.My drive to work is mostly uphill all the way and when I'm in town I usually put my foot in it at stoplights to get it moving (damn auto trans)but I can get out of the gas once I hit about 3000 RPMs. Quote Link to comment Share on other sites More sharing options...
iamtheq Posted March 17, 2004 Share Posted March 17, 2004 While I had it, my 1987 SPFI 3 speed AT 2wd GL sedan got no lower than 25 MPG, no matter how I drove it. I would average about 27 MPG and get at least 350 miles out of a tank of regular. This was combined city and highway driving. Stock tires. ECU light constantly on complaining about the EGR solenoid. My 91 Pontiac 6000, 3.1 V6 has gotten me 21.5 MPG average, with my low being 19.1 and my high being 24.3. I'll average around 300 miles per tank. Mostly back roads/city driving.

gmcfan Posted March 17, 2004 Share Posted March 17, 2004 my '84 ea81 5 speed sedan drinks gas like it is going out of style.

viceversa Posted March 17, 2004 Share Posted March 17, 2004 92 Loyale, 1.8 auto, consistently gets 29 in highway only driving, at 55-60. I also have a V8 which always gets 20-21mpg highway only. In town, all cars drop significantly. Quote Link to comment Share on other sites More sharing options...
