Default Help me w/ fuel economy / sanity

I'm seeing 23 mpg fuel economy in my mostly freeway commute. This compared to 30+ mpg for the same commute in my '90 Integra. Driving the same quasi-aggressive style.

I expected slightly worse mileage, say 26-27, but 23 has me re-thinking the whole "I'll sell the Acura and keep my beloved Subie" thing.

I've got 47K miles on the car, and the only not-from-the-factory items in there are a fuel filter (~15K on it) and an AMSoil air filter (cleaned <1K ago). Well, there is the removed snorkus too, but I don't think that matters much.

Any suggestions? Recommendations? Help me, as I'm seriously thinking of selling the Radio Flyer and buying a 4-dr 5-spd Integra GS-R.

TIA,

What were the stated fuel economy #'s for that year?

Hey Eric, that's about what I get with mine. I have a 17 mile commute, with 1 mile of city streets at each end, and 15 miles of highway in-between. The highest I've ever gotten was just under 29mpg on a road trip. I'm not so sure there's a whole lot left there for you, mileage-wise.

I find with my 2001 GT that varying the my driving "style" gives me the worst gas mileage. If I driver like granny I get 30 city, drive agressive I get 25, start doing a little of both 23. Might be the ECU trying to adjust to the driving.

Thumbs up Thanks, all.

A Tornado....

I just realized another issue here that could make some change in mileage... In Hotlanta, I was near sea level. Here in Albuquirky, I'm a mile high... Hmm... No. Stochiometric ratio....

Never mind. I'll likely just replace everything: tranny oil, diff oil, fuel filter, spark plugs, etc. See what becomes of it.

Should I replace the plug wires?

By the way, I always keep my tires at 35f 32r, so I doubt there's any problem there. Also, over 47K miles, they've worn evenly, so no hint of alignment problem either.

Thanks, all!

Tire pressure could help, even though they wear evenly they could still be a bit low. Also, I have a 98 gt wagon with 100k miles and a big, packline fiberglass roof box on top and with only highway/freeway driving I will get at least 25mpg. If you do some searching you will find that those that have done the snorkusectomy acual found that gas mileage went down. So, with the snorkus issue and the tire pressure you might have your fix, although if I recall correctly the snorkus is kind of a permanent deal. Oh, and my only changes are a K&N drop in panel, Magnecor plug wires and NGK copper plugs.

I run my tires around 38psi.

for what its worth....

Your tire pressure is way to low.

Pray tell, HIHO, what would you then recommend the pressures be set to for street?

Sticker in the door recommends 30 all the way around (or is it 32?). I had been running 38f 34r for a couple years, but when looking at the tires, the centers are more worn than the edges, so I backed the pressures down a bit.

Well Radio Flyer what the hell does that have to do with the tires that are on your car now? Most people go by the tires specs not whats printed on the door jam. You should run 36-40 psi in most tires bought these days. I run 38 all around and haven't seen any uneven tread wear.

Default Gas milage

Radio Flyer, gas milage is a subjective thing, (1) you cannot compare gas milage between your Integra and your Subie this is not even apples and oranges, you have to factor in weight difference, this is the biggest difference it is no accident that car makers spend literally millions of dollars trying to shave just a few pounds off of cars just to increase gas milage.

(2) your Subie has all wheel drive which your Integra does not, plus your Integra is a lightweight compared again to the Subie, and lastly if you got a hundred legacy drivers together their gas milage would be all over the map I would be really surprised if any two drivers got the same gas milage.

To close after having owned Honda's for many years before buying my GT, if I was up to my ass in snow I know what car I would want to own regardless of gas milage.

(clue) it would not be a Honda.

Thanks for your help, gang. Like I said above, I'll go in and change the fluids and spark plugs. I'm simply not convinced that I should be getting 23 mpg with a daily 20 miles of open freeway commute. I remember doing better than that (25-27) in Atlanta. (Bear in mind that four years ago, I handed the keys over to my wife so she could use the wagon to haul our kids around; and she handed me the keys to the Integra. We just got a minivan, and sold the Acura, so at long last the Subie is all mine again. My memory of mileage past could be warped, but it seems reasonable to expect 25 mpg or better like I remember getting in Atlanta)

I'm driving to Las Vegas next weekend, and will report on what I get as all highway mileage.

HIHO - I'm not trying to start a flame-war here. Your original message was simply not very helpful at all.

What does it have to do with the tires that are on my car now? I am still running the original equipment RE92s.

They are only now getting near the wear bars. I just ordered some Hankook Ventus K102s yesterday, in fact. They'll be on the car by the end of the week.
