emd61588 Posted April 10, 2011 Share Posted April 10, 2011 So I just bought an 06 LGT with a 5 speed manual trans. I have put about 500 miles on it, and I am getting roughly 19mpg. I just filled up my tank yesterday and reset my trip. I have half a tank and my trip says I traveled 101 miles??? I do not race the car because I have my 2month old son in the car with me. Does this sound a little odd to anyone? What kind of fuel mileage are these cars supposed to get? And what are some of you guys getting? Link to comment Share on other sites More sharing options...
AK_GT Posted April 10, 2011 Share Posted April 10, 2011 Wrong section for a question, but 19 MPG sounds about right. I drive about 60% highway and 40% city and usually get between 18-20 mpg. Link to comment Share on other sites More sharing options...
emd61588 Posted April 10, 2011 Author Share Posted April 10, 2011 Oh wow, wrong section indeed. My apologies! Thanks for the reply, I guess I was just expecting a little more out of the 4 cylinder but I guess that is the price we pay to have a car that feels faster then a V6.

AK_GT Posted April 10, 2011 Share Posted April 10, 2011 I pull about 24 mpg out of my car on highway only, but if you think about it, 1 Bar of boost pressure = approximately 2.5 liters of displacement. That means our cars effectively "feel" like a small block V8 My 2.2 liter Legacy would regularly pull 30 mpg on the highway and was pretty snappy, but the LGT's seem to be on a whole nother level.

ehsnils Posted April 10, 2011 Share Posted April 10, 2011 Moved thread to appropriate area. Seems to be reasonable figures for the car, but you may be able to make the figures better by making sure that it's in good condition with right oil, clean air filter and cleaned injectors. The best consumption I experienced driving my friend's STi was touching 25mpg, but that was a very conservative driving and almost never entering turbo boost RPM:s. Early shifting is the way to go, drive on torque rather than RPM, but on the other hand - if you do that you should have had a naturally aspirated engine instead. As for me right now - I'm driving the diesel, but I'm still on my first tank so I can't tell how good it is. Link to comment Share on other sites More sharing options...
Drift Motion Posted April 10, 2011 Share Posted April 10, 2011 it's a turbo, awd car... gas mileage will definitely not be up there if you drive alot of local roads, number will be sub 20 mpg Link to comment Share on other sites More sharing options...
Adoniram Posted April 10, 2011 Share Posted April 10, 2011 I had poor mileage until I did some mods. EL headers, UP, DP (catted), K&N filter, and stage 2 tune got me to 28.2mpg highway. Link to comment Share on other sites More sharing options...
SCHM1AN Posted April 10, 2011 Share Posted April 10, 2011 I'm averaging 18.7mpg since I bought my car in November. While I wish it were better, I knew what I was getting myself into when I got it Link to comment Share on other sites More sharing options...
.blackgt. Posted April 11, 2011 Share Posted April 11, 2011 I'm averaging 27.6 highway every time i got to school. Goes down to about 21 on local roads. i mode on the highway, s mode around town. I live in the hills too. Link to comment Share on other sites More sharing options...
Ballaholic Posted April 11, 2011 Share Posted April 11, 2011 I get about 25mpg city, I dont ever go on the highway at all. I drive pretty conservative only getting about 10psi boost when i gas it. Link to comment Share on other sites More sharing options...
ehsnils Posted April 11, 2011 Share Posted April 11, 2011 Filled up on mine, got 36mpg from non-conservative driving. But mine is a diesel. Link to comment Share on other sites More sharing options...
emd61588 Posted April 11, 2011 Author Share Posted April 11, 2011 Just found out today that who ever installed the spark plugs in the Legacy PUT THE WRONG ONES IN!!!! They put the non turbo spark plugs in!!! I was driving on the freeway today and all of a sudden my car started misfiring! The CEL was flashing. So I pulled into a gas station and called my buddy who has an obd2 reader. Came up as misfire in cylinder 2! So I figured I would check the spark plug when I got it home!

frank_ster Posted April 11, 2011 Share Posted April 11, 2011 fyi .. you car can display troubble codes through the gage cluster. wrong spark plugs ? meh doesn't really change anything. at least as far as my experience Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
car_cursed Posted April 11, 2011 Share Posted April 11, 2011 the boxer engine is also a poor designe for fuel economy, but great in so many other ways Link to comment Share on other sites More sharing options...
frank_ster Posted April 11, 2011 Share Posted April 11, 2011 the boxer engine is also a poor designe for fuel economy, but great in so many other ways eh ? the 2.5 i gets pretty darn good mpg ! for the weight of car and awd.

RJS5689 Posted April 11, 2011 Share Posted April 11, 2011 eh ? the 2.5 i gets pretty darn good mpg ! for the weight of car and awd. Our cars are damn light when you compare them to some of the offerings from Germany and even other sport sedans from Japan. My little GTI weighed as much as my LGT did and killed it in terms of fuel economy even though it made as much power. Granted my GTI didn't have AWD. To the OP: I get about 17-19 when I do a lot of stop and go driving. Link to comment Share on other sites More sharing options...
BigTDogg MA Posted April 11, 2011 Share Posted April 11, 2011 It's a battle for me to stay above 20mpg. Much back roads driving. I'd imagine I could hit 23-25MPG if I did a long road trip, but nothing yet. I wonder if a tune could help out with the MPGs at all? Thought I didn't buy the car for MPGs, still would be nice for a lil bump. Link to comment Share on other sites More sharing options...

You should see some improvement as long as you don't develop an addiction to boost; which you will . Link to comment Share on other sites More sharing options...
ehsnils Posted April 11, 2011 Share Posted April 11, 2011 Some people has seen a decline in mpg with stage 1 and improvement with stage 2. But a tune is usually a good idea. Link to comment Share on other sites More sharing options...
fightinchunk Posted April 11, 2011 Share Posted April 11, 2011 at stage 2 plus i'm getting an average of 21mpg with the occasionaly dip into boost. Link to comment Share on other sites More sharing options...

I plan on staying stock till the clutch goes. Afterward I'll get a catless up and catted down, maybe a reusable panel filter, and definitely a Stage II tune. LOL at "develop". I ran my Z32 for the first time this spring on Saturday. Evil smiles all around at 16PSI Link to comment Share on other sites More sharing options...

Yeah... that'll kill your mpg I rarely have high mpg, but on a road trip I'll average over 28 every time. Link to comment Share on other sites More sharing options...
jbrown Posted April 12, 2011 Share Posted April 12, 2011 I bought my car used w/ 84000 miles and i was constantly getting 16-18, after replacing intake filter, 1000 mile oil changes (3 x), and new tires w/ alignment i was able to stay just above 20. Now stage 2 i get at least 22 and thats driving hard... IM ADDICTED!!! But i agree stage 1 doesn't help in terms of fuel economy. Link to comment Share on other sites More sharing options...
melsie68 Posted April 12, 2011 Share Posted April 12, 2011 Hey guys, I am new to the import stuff having driven nothing but Chevy trucks and Camaros all my life. At almost $4/gal mileage IS a concern. I bought my '05 LGT-A5 for basic transportation and daily driving to work. I wanted a nice car with decent mpg- and something that didn't completely suck because I am very spoiled, so I chose the Subie. I am averaging 22.5 mpg driving to work about 45 miles each way through the hills of southeastern PA. I am in and out of boost the whole time, so I suppose compared to others mileage I am doing okay. Can someone summarize what is Stage 1 and Stage 2? I would like to increase my fuel mileage and don't really care about packages but I would install what is necessary to make the improvements. I understand modifications will require computer tuning and other possible changes. I do all my own work on my Camaro and C10 trucks including engine building, chassis fabrication, etc. so I plan to do my own work on the Subie as well. If this comment is not appropriate here, maybe someone could PM me or send me to the correct forum. Thanks in advance. Link to comment Share on other sites More sharing options...
