I was just wondering around what rpm or speed you guys shift at while just doing some normal city driving. I have just been shifting just under 3k but i cant seem to get it to be flawless and smooth. Any tips?

2300 to save gas 3800-4300 to have a little fun, 3300 for the best bov noise
ok maybe its the oil i'm using but my car likes me to shift over 4000 and closer to 6000, why buy a car like this if your worried about mpg and driving like its a camry. shoot my biggest complaint is most of my driving over the last couple years has been 20-30 mile jaunts on backroad with 45mph speedlimits. but still enjoy these cars your not gonna hurt it by DRIVING it, and i have tried to get better gas milage and mine varies from 19-21mpg. and that is after many attempts to get better milage so i said, the heck with that, might as well drive it like it was made for.
4000+ and SMILE and when i say 4000+ i don't mean i floor it every gear change.

Dude 4k is a bit high for daily driving, and 6k is just absured.

It is high but look at the mileage he says he's getting!
Id shift there all the time too if I got MPG like that. Sadly I think his math blows.
ever since i read this i do the same and my gas milage is insanely good. thanks a lot

Im pretty sure this is not the best thing for your engine and retarded advice to follow...ever since i read this i do the same and my gas milage is insanely good. thanks a lot

honestly, my s2 car can lug down to about 1500, it will make about 1 psi with lite throttle and can lug around pretty well
I'm not a fan of reving the motor high, it produces more wear on your motor.
the high load low rpm thing is a myth. that only happens on a carb, when there is a lot of vacuum.
the motor has to make X power to go your speed, if it can make X at 1500, then your not wasting gas running the motor at higher rpm.
that being said. I upshift on 27-2800 and downshift at 2 grand when driving conservatively. the whole buy an sti to save gas thing is stupid, you don't need to drive it all out all the time. and it's nice not to put 15-20 dollars in your car everyday.
I get about 19mpg city, 25-26 freeway going the speedlimit in the 2500 range. when I had a GSXR-1000 I got 49 mpg riding it between 2-4k rpm. which is amazing for a liter bike.
It got my STi because, for it's performance, good on gas, quick, great handling (which increases mpg by not having to slow down for turns).
if I wanted a performance car that got shotty mpg, I would have gotten an M3. turbo cars are just more efficient.

In reference to my advice, the OP said city driving. I assumed 25mpg speed limits, stop signs, traffic lights, a bunch of other cars, and college students crossing the street everywhere possible. In this situation, I'm lucky if I even hit 25mph and I certainly don't need power on tap, which is why I shift so low. A side benefit of shifting that low was the gas mileage. I do not drive like that to save gas - there's just no need rev any higher or I'd take off like the ***hats with exhausts that pretend a college campus is a race track.
Someone mentioned listing mods. I have lightweight crank, power steering, and alternator pulleys. That plus Enkei RPF1s and I have reduced rotating weight/inertia by over 11lbs. This is why my car doesn't lug like most. I'm also not trying to go WOT or expect instant response at 1600rpm.
If we are talking about open city roads or the highway, then I shift around 2500-3000rpm. I generally don't hammer it at every safe chance, but the situation more than anything dictates when I shift. I have no problem going WOT to pull out in front of someone, pounding it on an entrance ramp to fit into heavy traffic, or passing someone on a country road.

I know its been said, but this was just hilarious!!!

Stop perpetuating bad information. Granny shifting isn't "hard" or "bad" for your engine. Neither is shifting at 5K. All of those RPM are within the operating norms of the engine design and within tolerances.
We're not talking about prolonging the life for 100 years, get over it.

If you knew how a transmission worked, you would understand that shifting slowly, allowing rpm to drop near the next gear ratio is the only way to drive it where it's not wearing on it's parts.
every time you shift from high rpm, you push the shift collar's teeth into synchronizers which match the speed of the gear to your collar's. big rpm differences when shifting puts a lot of wear on them. and so does shifting quickly.
that's why if you shift slow, it feels like the stick falls into place.
I think he was saying it's bad to shift at 5 grand all day cause it puts unnecessary wear on your motor, and tranny.
my car can pull 6th gear around 1800 rpm with very little throttle up little hills and around corners.
*If your basing your posts off what "momma told you", you might not want to*
more rpm on motor=more wear. higher rpm difference in tranny=more wear on synchros

actually i probably shift more times around 4-5000 but i don't hesitate to drive out to 6000 and even 7000 RPM's i have 70,000 miles on the car with no problems and i just recently changed the clutch for the first time and i Rallycross this car quite a bit and launch fairly hard.
SO my transmission has held up well and the clutch.
AND i have no problem doing the math for MPG. it aint rocket science. and i get 19-21 mostly 20 that's with Air on, and driving as stated above. i have tried driving it like it is not a sports car and got 21 at best, so i decided to enjoy my car everytime i drive it. that siad i don;t speed per se but i do reach the speed limit quickly.
i have tracked the car some and autocrossed some too. these cars are made to be driven.
