05-09 LGT Gas Mileage

[smittydidit]

I've only had my '05 5MT sedan for 3 tanks and so far I've been averaging ~23.XX mpg. Its catless, 3" turbo back, VF52, forged pistons, head studs, P.R.E. tuned, I think I remember the previous owned said it put 287hp/275tq down @ 16psi.

[grovlet]

Wife driving -- Stock = 21 MPG around town / Stage 2 = 17 MPG around town

Me Driving = Who Cares = Turbo Powah!!!!

[idiot4hire]

I am on vf52 with support and My computer says 34 so that what want to believe

I find that the dash computer varies depending on driving conditions. It seems the steadier the drive the more accurate. For daily commuting if the computer says 25.5 then I can realistically expect somewhere in the 24s. The most accurate it has ever been was on a road trip, computer said 30.9 and actual was 30.4. The whole time i was cruising right around 68-69mph, so just before boost played a factor. 100% stock and 162k miles.

I've been told this variation suggests you need injector cleaner

I've only had mine for about a month. The 1500km (1000 miles) I've done I've averaged 9L/100km (26mpg). Usual driving on open road gets me 8L/100km (29.5mpg).

Ej207, OEM display:

I'm currently at 27mpg(66mi on the trip), about 70% highway. On the other trip, 990mi/24.6mpg(last week it was around 24.9 but went down after messing around with my friend's Saab on the highway).

 

The best I've seen was during warm weather, where the best I got was 30mpg going to work(steady ~60mph, no stops just slowed down at some intersections). During cold weather, it tanks. I think the best I got was around 21mpg and it was around 30F.

 

I don't know if it's because my car needs an alignment(pulls to the left, slightly though), or it's just inherently the AWD drivetrain, but I have a hard time coasting(downhill) without losing speed. Besides in the mountains, the best it'll do is maintain speed...otherwise it's slowing down. My Accord and Civic, on the other hand, would gain speed on those same downhills.

I've noticed the same with mine. Mine will lose speed while coasting much faster than any other car I've ever had. The only thing I can think is the greater amount of rotating mass we have in our cars drive train.

Geez wish I could get that kind of MPG. My comp says either 19.5 or 19.8, pretty much consistently.

 

Even the 3.6R we just got it's now sitting at 21 MPG. Still far less that what others seem to be getting on here.

[Connor]

Averaging 22 per tank on my stage 1 2006 Spec B. On the highway I get 27.

[stuck686]

20-21.5 AVG. stg 2

 

I say im going to baby this tank every time i fill up and that lasts about 10 miles

I think mine coast pretty well. I will say my wagon seems to coast better of the two cars. Even compared to the Civic.

I probably need cleaner injectors, as the injector cleaner doesn't really do much lol

Then maybe I have an issue. I've wondered for a while if I didn't have something wrong.

Since I've bought my legacy gt my computer says I have gotten 23.1 mpg. That's over about 5500 miles and mostly winter with winter blend gas and a lot of warming the car up.

So I'd imagine I can get a couple more mpg in the spring/summer.

[jinholee]

I'm driving a stock 05 Legacy GT Limited Sedan and I average about 22-25 mpg. Lowest I've seen on my car is 19 mpg, and highest is 30 mpg on the freeway.

[gimpydingo]

When I first got my 07 I was getting 20 - 21 MPG, but it dropped to 19's about 6 months after. 2 years later it sits in the 19's. Mixed freeway, mountain road, stop and go traffic. The 3.6R is now at 21.3 MPG.

[andyengineer]

I live about 2 miles from work and have to stop at the post office which is a 5 mile trip total daily. I get about 17.4 consistently with AP installed set fro and running 93 octane. I do not get on it at all, just once in a while. For the most part I drive like I have an egg under my right foot and I have the stop lights timed for least stops.

[Masaru]

Fuelly is telling me 23 MPG on my Stock 08 Legacy GT. Most of those miles are from being on cruise control at around 70 on the freeway, it starts to dip down to 19-21 if I'm rolling around the city a lot.

[chimera]

Stock GT '07 wagon getting 8.5km/litre (20mpg) Those getting 30mpg need to sell and buy a 1500cc hatchback... you're not driving it hard enough! :-)

[K2e2vin]

...already have one! 1988 Honda Civic HB with japanese D15B VTEC motor swap, It got 54mpg hwy last time I measured.

[08 LGT]

My office moved and now my commute has changed from mostly highway to a couple miles of stop and go stoplight traffic.

 

I get about 18.5-19.5 miles/gallon, maybe 19.5 if I drive like a real grandma. Pretty much the city mileage EPA estimate. Again, this is city MPG only.

Make sure you take the car out on the highway every now and then to get the oil hot enough to boil the water out of it. You may want to shorten you OCI too.

 

What oil are you running ?

I was easy on the gas over the weekend and today and put it in "I" mode which supposed to give better mpg. I was able to average 26.4 mpg mixed highway and city. Probably 70% highway going around 75-80 and rest city. Before that average 23.1 mpg driving in sport mostly.
