Gas Mileage Issue
 

Okay so a few things to know. I do not rev the car pass 3000rpm. I usually just cruise like at 2000. I also don't break hard. I checked the mpg on the gps and it says i have 18.8. Is this normal? What can I do to increase my mpg. Gas is expensive :icon27:

Sounds fine, this is not the car if you care about MPG. Sell it and get a Honda Civic. Half the HP, half the Displacement, twice the MPG. I wish I got 18, I get around 15-16

estimated is 19-29 right? but since the car is aging i figured ill lose a few miles. but i didnt think it would be this much lol i guess i was just worried. anyone else get higher mileage?

average driving, 15mpg
more careful driving, 18-19mpg

OP you're getting pretty avg. mileage. Welcome to the world of high HP 6 cylinder motors. You gotta pay to play.

I have also tested out a tank of gas driving the way you mentioned, not going past 3,000rpm and I really didnt notice that huge of a difference in gas mileage than when I drive hard. Not that big of a differnce to keep me driving it hard and having a little fun here and there anyway.

I have been just using fill ups and the trip mileage . but I get an average of 23 . Granted , i am using premium gas and most of my driving is 45-60 mph on highways.

Thats average/normal. Mine is 20.4, but most of my driving is at highways.

Seems low to me. I drive fairly hard, but nothing crazy. I usually get 20 to 24 mpg. I willing to be your gas quality might be part of the issue.

Ya think....^....I can't wait to hear how much profit the gas company's make again this year! You're getting better gas mileage than most of us. Use your cruise control when ever possible, that alone will bump up your gas mileage.

That's not too bad. I get around 23mpg. I drive about 70 miles a day to and from work, about 50 of which is highway miles. I rarely go above 3000 rpms.

even if you're keeping the RPMs low, you still need to consider how much load you are placing on the engine at those low speeds. if you're at like half throttle as opposed to 1/4 throttle, youre going to eat more gas... slow acceleration, keeping under 3000 rpm should help conserve more gas..

^ THAT is said perfectly.. less throttle if you actually dont care about how fast you accel and just use 1/4 throttle for your driving you can get pretty good milage

Yea I don't accel hard at all. Well I use plus gas at shell. Maybe this could be an issue?

You know, I've read a bunch of threads on here stating that you shouldn't jack rabbit starts and run at certain rpms, but in reality it still might not be the most efficient manner of operating this particular vehicle. Some guys over at the Subaru forums have mentioned "brake specific fuel consumption" in which an engine achieves maximum fuel efficiency at it's peak torque range. It's gets complicated when most of our driving is done under part throttle conditions. You'll notice that we still get lousy mileage even when we're in 6th gear the whole time not going faster than 50mph. In my personal experience I've gotten nearly the same 20mpg when I'm hard on the gas. So, I'm interested in learning more about the thresholds of our particular vehicle now that there's a great awareness for it.

Here's a link I found for general strategies involving achieving greater fuel economy:
