Gas Mileage
I just did some all freeway driving, and i got 410 miles on my tank of gas. I was using 87 and averaging about 80-85 mph the whole time. That works out to about 25mpg. Is that about what everyone else is getting? I have a manual NA sedan.
Oh, and this is added, i get about 360 city, that works out to be 22.5.

i doubt any of those things would increase my mpg by 1 on the freeway. Once you have your equipment rotating, it doesnt matter how heavy it is, the only thing that harms you is friction. Thats wind resistance and parastitic losses from the drivetrain. Gutting the interior would help in that there would be less weight on the wheels, but the car wouldnt notice it, the difference would be too small.
what would help is to lube everything, use a light weight oil, low rolling resistance tires, fwd, have a sedan, disconnect the AC, etc.
I was just wondering if that was normal. I had a mechanic (that i don't trust) tell me that i had a failing cat, and a long stint at high rpm would definately make the cat be noticed. Also, its just a poll, im wondering how those 17psi guys do.

I didnt expect to improve mileage but after upgrading my ignition system I improved about 6.5%
I drive at 80 mph with many full throttle passes and about 10% city driving and Im getting 21mpg. The slower I drive on the highway and the more cruise control I use the better.
Edit the poll to have three, 21-23 and 24+

I do almost all highway, usually in the 65-80mph range, and I get 26mpg and above. I've got a '90 LS sedan, AWD, NA with all-season tires, MRT full exhaust system, and K&N air filter. This includes going over a small mountain everyday too. A/C takes a bite out, but my mileage has never gone below 24.

My car is weird. I've gotten as good as a 26 average MPG on one tank and as bad as 19 average MPG on another tank. However, since I actually think I can tell a difference between open-loop and closed-loop, (car feels faster and smoother in open-loop, or when cold), I wonder if my O2 sensor might be on the fritz, maybe the ECU closes the loop and the sensor starts dumping way too much fuel in it.
I should check my spark plugs and see how carbon-gunked they are...

I don't have specific numbers handy, but I do remember getting an extra mile or so per gallon after upgrading my stock ignition system with an MSD DIS-2, Magnecor wires, NGK copper plugs, and a Diamond coil pack.
The way you drive can make a big difference in your highway mileage. A lot of the time even on the highway I'm continuously varying my speed just to deal with traffic, so I'm accelerating a lot. That takes a big bite out of the mileage.
It's actually not always true anymore that A/C hurts gas mileage. Most modern A/C compressors hurt mileage less than the extra drag of open windows.
Subarus have never been really good with fuel mileage. They're fairly heavy, especially with AWD systems, and the AWD systems also have a good deal of parasitic losses. The boxer fours are great for torque, not for fuel economy.
I remember many years ago when I was in the U.K. I picked up a copy of Top Gear magazine at a train station. It's a really cool magazine! That issue was one where they teamed up with J.D. Power to do a study on what cars people were happiest owning. Apparently before that year the Subaru Legacy had held the top ranking, but that year it fell to second. The Impreza took first. :) But to get back to the point -- it received a 5 out of 5 in all the subcategories except fuel economy, where it got a 2 or something.

I haven't had this problem with my Legacy Turbo (I get around 24mpg (imperial not US) in town and 28ish on a run) but my previous Ford Sierra XR4x4 (see http://www.fasterfords.dk/other/The%20s ... 0range.htm - scroll right down) had a SERIOUS mpg problem after water got sucked into the intake knocking out the injection metering - I was down to 9mpg on a run...eastbaysubaru wrote:I'm currently getting ~160 to a tank. Barely above 10 mpg. Any thoughts guys?

My mileage sucks most of the time but it's my own fault.I can't believe how fast I go through a tank but I drive hard.iluv2xlr8.on the other side when cruising on interstate on a road trips I can't believe how good the mileage is.don't really know any #'s though If I had to guess I'd say 16-17 city maybe 24-25 highway.thats just a guess though

21mpg
I drive a roundtrip of 70 miles a day almost all freeway at about 80mph. I get 21mpg consistently. Doesn't matter if I feather it or hammer on it. I thought that kind of sucked until I started looking at new cars. Anything with AWD and any power gets about the same mileage.

I get 25 highway @ 80-85, ~21 @ 100 w/ A/C (through Nebraska), and 28 @ 65 (I can't believe I was actually able to go that slow, but there was a girl in the car who i don't want to know I'm a maniac). Of course, my car's a sissy fwd.

My gas milage is lousy I've never gotten close to the numbers that I've seen posted, (except eastbaysubaru's). around town, maybe 230-240 miles to a tank. on the open road, maybe 280. I think the thing is my right foot likes to see the boost needle on the positive side.
