around 2.5k RPM if you want the best gas mileage. but I generally shift around 3k rpm when I'm not messing around.

1 to 2 is at 15 mph, 2 to 3 is at 25 mph, 3 to 4 is at 35-40 mph, 4 to 5 is at 45 mph. This is just for best gas milage. If you want more performance you'll have to rev it out a little more. But you already know that....

about as low on the tach as possible while still accelerating... then, turn into a new car dealer, and buy a hybrid

Its not about rpms as much as it is keeping the car out of boost.

^^agree; it's more important not to go past half throttle. If you have a boost guage it's easy to use it as a fuel economy guage.

Isnt it also bad to shift too low and lug the engine, thus causing it to use more gas to keep it running?

this gives me an idea... can you mod your wrx's so you can take out the turbo... so that you will turn into an ordinary 2.0L engine... then your fuel economy will definitely increase.

Lugging sucks for your car....I used to do it in my celica and p5s and after a while i could totally feel it in the clutch. The tranny started to soun dlike it was about to fall about too. Im being more careful to not like the WRX, which usually means not letting it go below about 1800 or so RPM.

lugging the engine does a LOT more harm than simply using gas.

Some say lugging your motor is worse than redlining it...and that is quite bad. Just learn to shift through the gears to keep your rpms above 1.5k, it's pretty easy to lug the motor on our low displacement engines.

Check your manual, they tell you which gear you should be in for a certain speed range. They know the best way to conserve fuel.

If you are slowing down for a speed zone, 1800 is OK to downshift. The correct RPM depends a lot on what you are doing, though. If you are accelerating or climbing a hill you need higher RPM.
