Can anyone tell me the best shifting points to get the best fuel mileage on my SI?

Hahah what is this Need for Speed??

The best advice I can give is to keep the rpms low (below 3500), try to lay off the gas a lot, shy away from excess baggage, and only drive when you have to!

BTW, does bogging the engine also use excesss fuel?

Good question. I'm not entirely sure, but I wouldn't think so...

I would like to think that having to give excess throttle input would lower the gas mileage by a small amount, but I'm sure it could be tested either way.

yes bogging the motor burns excess fuel you want to keep the motor revving where its against the least resistance and to get optimal gas mileage you want to drive at a steady speed as often as possible trying to avoid unnecessary accel/decel. ex: speed limit in this part of kansas is 45 mph on the street 65 or 70 depending on the highway, if i'm driving on the street i want to get to 45 in reasonably quick manor because just starting off the line trying to feather the gas pedal wastes fuel, you'll want to slow down before you get to stop lights so if possible you dont come to a complete stop. starting from a dead stop is the most fuel consuming thing you can do other than top speed driving. also air your tires up properly and your alignment is good so you dont have extra drag from the tires. a lot of these things i was able to verify in my parents lincoln towncar it has the digital dash with the instant and average mpg's.

It was already stated up top shift between 3000 and 3500, Maybe lower in the city. If you wanted gas mileage dx tranny would have been a little better
