He's in Hawaii, so that could easily be for regular gas. And heavy traffic will kill gas mileage. My RS would only get 23-24ish when I wasn't able to stretch it out on the freeway, and I had advantages over a stock '06.

Nope, Miata. I just think those commercials with Peter Stormaire are hilarious.

I kinda figured. I'm like reading in this thread that a lot of peeps are getting around 300+ miles w/ aggressive driving. I'm gonna check my tire pressure tomorrow.

BTW,about the premium gas,.. shoot idk.. a few of my friends as well as some peeps in the forum said that using premium gas helps fuel economy.. and also it gives more power.

Certainly, I'ma go check out my tire pressure tomorrow. thanks.

Use what your Impreza Owner's Manual recommends for your car model. The WRX and STi must use premium fuel to avoid detonation in daily driving, as any lesser fuel will cause pinging under load. You may be wasting money because premium neither helps fuel economy nor gives more power if your car's engine does not need it.

Split off your tire pressure question to the Maintenance & Warranty Forum so we can try to stay on-topic.

yeah, night... you dont need premium in a standard Impreza (Im pretty sure, but check your manual, or spec sheets)

Premium fuel only helps fuel economy when your car is tuned to that specific high octane... and thats only because running lower will cause detonation/compensation and run rich to avoid detonation, etc making you use up more fuel.. you will get the best economy out of what the engine is tuned for...

Hopefully your tire pressures and proper fuel type will eliminate your issue... get some 27-28 averages hell, go for 30! Let us know

How in the world are you getting almost 22 mpg with an STI???? I just bought an 06 Forester XT (turbo) and am HORRIFIED by the gas mileage! I mainly do only city driving, but the mileage is always around 13 mpg!! I researched the heck out of this car before buying it and everyone on the message boards I saw said it usually gets around 18-20 in the city, except for one guy who said his got around 12. I thought he probably wasn't calculating it correctly and wrote him off. Now, I'm in the same boat! I only get around 200 miles on a tank of 91 octane California gas. I've only had the car since the end of March. Weather is not an mileage issue.

Also, even when I'm driving on a cold night, the driver's leg/foot area gets inordinately hot. When I touch that side of the console (where the radio is mounted, etc.), it's burning up. The passenger side of the console is much cooler. Anyone else experiencing this? The dealership is gonna think I'm nuts when I bring it in this week. The car only has 1400 miles on it.

And, no one ever mentions how damn HOT these cars get just from sitting in the sun! OMG! The thing is like a Swedish sauna, even with the reflective shade I always put in the windshield. I've never had such a hot car before. I'm gonna have it tinted as dark as a limo this month because I just can't stand it! You'd think the car was black, but it's not. The car's a dark silver.

Gotta say, however, that the thing is just a BLAST to drive. LOVE the car! Best car I've ever driven (and I've had a Porsche and BMW!). It's just hotter than heck and gets really lousy gas mileage (which sucks because the reason I bought the thing was to get better mileage than my regular, truck-based SUV, which gets 10 mpg).

I'm gonna check the air in my tires this week, but I'm assuming that the dealership inflated them to the proper numbers. Any other suggestions? I even removed the roof racks hoping that would help! Will the window tinting help?

Regards,

Samantha

Unless there's something amiss with the engine controls (ECU and fuel management), I can only guess that the poor fuel economy is due to traffic, terrain, and driving style. The latter has much to do with both city and highway mileage, but if you have to drive in a lot of stop and go traffic conditions, there isn't much you can do to improve the situation.

How is your highway fuel economy? If this number is way off from the EPA estimate during constant highway driving then maybe there is something not right with the vehicle.

I'm going to link to a new thread on this topic so as not to stray too far off-topic in this fuel mileage thread.

You haven't supplied enough information. See first post in thread. Please calculate actual fuel economy, which is the number of miles travelled divided by the precise number of gallons used since last fillup. 'Guesstimates' of miles to the tankful aren't precise enough since the gas gauge is far from a precision instrument.

A few days ago on my 02 wrx, about 50/55 whp/wtq above stock -- TMIC, IC hoses, UP, TBE, ECUTEK dyno tune, stock turbo.

207.7 miles / 14.4 gallons = 14.42 mpg. 95% street 5% freeway driving.

I seem to always be on boost and flooring it constantly.
