lol...same here!

I'm with fastback ford. I get 13-17mpg MAX. Think i've seen 19-20 1 time in my life. Doesn't matter if it's highway or city, granny driving or smashing the pedal. This car's gas mileage blows dick. I love when people post that they get 27-29 in these cars. I don't believe one word of it.

I have a diablosport 93 tune, CAI etc. Sure my 3.73's and my heavy 10.5" wheels/tires in the rear definitely don't help, but 13mpg? I'm a constant 15mpg easy no matter the driving. And people wonder why i barely drive my car anymore... I have a honda 4 banger that gets 30mpg no matter if its city or highway driving. lowerst ive gotten was 27 and highest was 35. No reason NOT to drive that thing. It gets nearly 3x the gas mileage as the stupid mustang.

Prior to 4.10s (still haven't had to fill up since getting them installed) I would see 17-19 city pending on how lead foot I drove and around 23-25 on the interstate.

If you go the freeway route, keep your windows UP. Also a lot can be gained from keeping your tires up to proper inflation level. I fill them to max psi cold. Sometimes I'll fill them 5 psi over maximum recommended if I'm taking a trip. As others have said, take all the extra weight out of it. Weight is a KILLER when you're looking for MPG. Also lower is better. Make the air go around the car, not under it. I don't know if your's is lowered, but if not, lowering springs would help. And if available a lower air dam will help. Even if it's only 2 inches lower, it's a gain.

**Edit** For safety, stay with manufacturers recommended tire pressures for driving on wet roads, rain, snow or ice.

Forced Air

I try to keep the engine towards the bottom half of its powerband during my daily commute. This usually means keeping it right around 2k rpms. I have a 30 mile round trip through the dead center of our city. Average economy on the car is 21 mpg.

I'm hoping this number improves slightly as I learn how to best drive the car but overall, I think it's pretty darn good for a V-8.

Back when I had kids, some in college, I had an '85 Corolla sedan (the last of the RWD models), a whopping 74 HP at the crank. With the windows down it maxed out at 92 mph or so but with the windows up it could do a solid 105...

Did it feel safe at those speeds in that car?

Of course not, traveling at any speed faster than one can walk does not "feel safe". Which brings to mind the following quotes:

-----------------------------------------------------
Evil Kneival asked once before performing some feat, "Do you know you can do it?"

His response: "If I knew I could do it what would be the point?"

-----------------------------------------------------
Don Prudhome asked after returning to racing after a long recovery from a very bad and fiery crash: "Are you afraid of returning to drag racing?"

His response: "No, I am afraid of losing."

-----------------------------------------------------
Mario Andretti speaking with Don Garlits back in the days of the "slingshot" dragsters (where your legs wrapped around the bell-housing and clutch):

"How do you get those great big ***** in that little tiny seat?"

==========================================
When you reach the point, physically or mentally, that you "feel safe", traveling in/on any motor vehicle, you have reached the point at which you are most definitely "NOT SAFE"...

keep the RPMs below 2,000 RPMS at all time.

I used to buy into the whole drive 65 thing but really cant tell a difference in going 75 honestly.

You can also remove your rear spoiler as that creates a greater drag coefficient. You could always swap to 2.73 gears.

you can try weight reduction.

I read somewhere that one window down is equal to 5-7% in aerodynamic inefficiency (drag) I don't know if your Corolla had 2 or 4 down/up (and the math becomes more complicated with rear windows down because it's not a straight 5-7% due to the air spoilage from the fronts being down) but using your figures of 92 mph windows down vs. 105 mph windows up & 2 windows for 14% it comes out pretty close. 104.88 mph with the windows up. I guess their testing was pretty accurate. The size of the windows seems to be relative among most cars since smaller cars = smaller windows, & bigger cars = bigger windows so the test & comparison stays consistant for most cars.
