3000 Rpm = 30 Mpg

Sorry but I will Vtak my Si whenever I feel like to.
It's meaningless when driving the Si like a grandma.
If people want to have good mpg, they just get an EX and happy with their MPG.
I am driving average 50miles/day.

I don't drive my Si like a grandma and I live in the 4th largest city in the us fighting traffic twice a day. I would say I am doing 65% city 35% highway, I average 29.x. On long trips I can easily hit 32mpg. The key is acceleration and change of speed, not so much how fast your drive. If you are steady on the throttle and minimize the amount of speed changes, then the mpg will be up there.

Even if you go flat out to highway speeds that should have a negligible effect on your highway mileage if you travel a significant distance. I generally accelerate aggresivly onto highways as well.

Though I should add those highway miles where I get 31+ are cruising distances. Not just getting on the highway to go to work.

Still, a difference that great you'd have to be on it a lot. I get on the throttle aggressively periodically on the highway but usually I end up being pretty consistent with my speed.

22 is close to the lowest I get in the city. 25 is what I get combined 70/30 City/Highway.

The point is that you CAN get good mileage out of your Si if that's what you choose to do. 90% of my daily driving is done where I can't run my car to anything more than the top of 1st gear and 75% is done where I'm directly behind another vehicle on two lane roads meaning that running it to redline until I'm inside the exhaust pipe of the car in front of me is a rude and immature punk thug way to drive a car.

A friend of mine has a 500+ HP GTO. Is he "driving like a grandma" because he's not whipping out 9 second 1/4 mile runs at each stop sign? I NEVER see him driving like a maniac! Many others that I work with have Vettes and other high HP cars and "drive around like grandmas" 99% of the time. They are beyond having to prove themselves at each light and stop sign and have bought the car for themselves. You think they don't ever consider ways to improve their daily MPG? Check out their forums and let me know.

yup, and i see your from Nor Cal also. They are getting 30+ going 55-65 forget it....you cannot drive that slow on 280! The flow of the traffic seems like its 80 mph...

SF to Palo Alto and back daily. I'm averaging 27mpg. Maybe because I get stuck traffic on 101.

Exactly! It's pretty much UNSAFE if you travel at any speed below 80mph on I280! It's even worse on 101 or 880 bc it's always bumper to bumper traffic ha ha...

Am I safe to assume my MPG will increase after my first oil change? I am currently at 1,235 miles and got quite some bit till my first oil change...

Another newbie car like mine.. I'm at 1100ish as of this morning.
I've got to get my rear in gear and learn up about service for these cars.

Shingles you make a good point.. It's all about how you baby the gas pedal, use your gear changes and terrain to assist. Winding up into big RPM's prior to upshifts is where the gas goes bye bye.

Lower RPM's (but not lugging) = Higher MPG's = Less drive-train wear = Normal :| fun levels.
Higher RPM's = Lower MPG's = More drive-train wear but = Higher :) fun levels.

With the six-speed, good conservative acceleration, early upshifts when possible and slow-down anticipation (coasting where possible), I hope to get some great mileage, if I can help it (resistance to get all happy with such a fun fun car). :)

No, unless your oil is really worn out you shouldn't expect to see any sort of meaningful change in MPG after your first or ANY oil change. If you do then you've waited too long to change it in the first place!

I did my first oil change last night and managed 28 MPG on a 10 mile warm up run that was pretty much all . The key is this was on open roads so I didn't have to scrub off all of my speed for a stop sign or light every 300 yards. Did another 5 mile drive after the oil change (gotta heat up that oil so it will drain into the pan and you can get an accurate read on the dipstick, right? ) with some at the end and managed 27 MPG.

I noticed something interesting now that I have my header and exhaust installed. When I keep it in gear after hitting high RPMs and ride the engine back down with my foot completely off of the throttle (this is how I first broke the engine in) I can hear and feel VTEC disengage. I don't remember that before I did my mods. Engine sounds are much easier to hear with the modded header/exhaust!

[bsbabcock]

Oh don't make me worry that I didn't break it in well. hehehehe That's all I need now. :)

i always thought that if you cruise on the freeway at 75 you get 30+MPG

You should be able to get 30+ at 75.

I have full mods, P2R Spacer, 2 P2R TBG, P2R IMG, Injen CAI, DCRH, Hondata Reflash and an Apexi WS2 exhaust system and my mileage has been going down. Although I don't track my mileage and hardly vtec anymore, I've noticed that I have to fill up at least every few days.
