What is your gas mileage?

you swapped from twin to single??

 

Yes, I have a VF28, and DCCD from an STI, and some other goodies. http://img.tapatalk.com/d/12/10/04/y6ahuqa4.jpg

You can see the controller, and my ridiculous e-brake handle, in this picture.

It turns out my o2 sensor was inop. New sensor is installed and ill update you all later.

nice, looks clean

I get 27-29. Ive been using shell 93 for the past 100,000+ miles because the engine pings. Shes got almost 232,000miles on her now and mpg is still good! A lot of highway, some stop and go

26 mpg!

I was averaging 22mpg in mixed city/highway driving. I switched to a K&N ari filter a few months ago and though the engine response is better I notice my mileage seems to have dropped to 19mpg in mixed driving, even when I try to be conscious and conservative of my driving style.

2003, Legacy Wagon, stock, 130K miles.

Have also noticed over the years that tire pressure, even small changes, greatly affect the mpg.

2001 Legacy GT Limited 5-Speed Sedan.

 

Running 91 octane I only get around 20.5mpg with mixed city/freeway driving (never exceeding above 3,500rpm).

 

I feel like I should be able to do better but aside from tire pressure I don't see how a drastic change in my mpg would be possible.

I'm averaging a little over 21 mpg on the streets and I can get as much as 31 mpg (!!!) when I drive gingerly on the highway. I actively monitor my mpg using the app 'Dash' which uses an OBDII reader to monitor your driving habits. I'm sure without the app, I'd probably closer 26 mpg. Running totally stock on a 2000 Legacy GT wagon.

im getting that.

I get 25-27 mpg most of the year and 23 mpg in winter time.

I have a 01 limited gt, 5 speed

 

The best I got was on a trip, 26mpg... that was during the fall when i first got her,

during the winter with 50/50 city and highway i get 21-23mpg.

 

Hoping during the summer it will go up

 

Anybody use a scangauge or something? I really wish our cars had the built in readings. Im very jelous of my brothres 08 ford fusion and my girlfriends old caddy.

Would a throttle controller help MPGs if you have em set to economy setting. I was considering getting one.

if anyone knows or is using one?

Ej259 with 78,xxx on 87 i get 24mpg City/highway driving

I get around 24 city and 30 highway. I've used premium almost always since I got the car, mainly to keep the engine running clean. I do notice it runs a little more smooth using premium over regular.

Adding a K&N air filter, NGK iridium plugs and wires, and a fuel treatment helped me gain around 3-4 mpg. It might also be time to replace your fuel filter

I just broke my record the other day and got 22.5mpg (city/highway mix) using Shell 91 octane.

Since I already have brand new OEM Plugs and Wires, I think I'll try replacing my air filter and fuel filter like you are suggesting. Thanks!

Octane does make a difference and how much Ethanol %. I use Premium only to avoid the ethanol. The higher priced fuel has more BTUs and therefor more MPG out of it than high % ethanol blends. A few years ago I ran all three grades one at a time as a test, two lowest had ethanol 20% and 10%, premium 0%. 20% had the worst fuel mileage and was the cheapest, premium was just the opposite. When I did the math to see what it cost me to drive per mile the cost of each grade was all within a few cents of each other. Since then I only use 0% ethanol blend, and have only seen that available in premium. When water gets into an ethanol blend it causes phase separation...bad deal, look it up.

 

On premium I've been getting ~24 MPG per tank, this is coming from the Ultra-Gauge I have installed in the car. Check it out, it is a handy tool to instantly have MPG feed back and try to adjust driving.

 

On a 12 mile trip to work, 50/50 city highway (70 MPH) I can get 22 - 24 MPG, while on the highway my instant best average is 28 MPG. With the AWD and cold temperatures it is difficult to do better. I've notice in my other (non Subaru) car the ambient temp really makes a difference when below 60°F MPG really tappers off.

26 mpg!

 

I have not seen 26mpg since this post.

 

I regularly get 18.5 mpg now.

 

Its sucks buying premium. It costs me $80 to fill up in Japan.

NA or Twin Turbo?

Neither.

 

Swapped from twin to single turbo.

 

Also, my AFRs were off for a few months and I just figured out why. So maybe my MPG will go back up.

The ambient temperature is up today 40 deg. F! I got 29.9 city/highway 12 miles on the way to work today. I drive in 4th and 5th gear as much as I can in the city and keep the RPM low. I also try to "short shift" as much as possible in the city and keep the RPM low. Accelerating a little harder helps spend less time sucking fuel trying to get up to speed. Once at speed the I use a feather touch on the throttle to keep the car at speed.

 

The highway is a little harder to work with, too much aerodynamic drag.

Personally, I think chasing MPG is a waste if time. Just drive the car. If a person can't afford gas, find a different means of transportation.

 

Also, buying a new or newer car for the mileage benefits is out weighed by the extra cost of the vehicle.

Just broke my record the other day and got 22.8mpg City/Highway using Costco 91 octane.
