i've gotten about 27-28 mpg mostly highway driving.. and im cruising around 75mph... shifting around 4-4.5rpms

 

I increased my tire pressure on my last tank. All city, got 27~mpg. Very little vtec.

I took the car in for service last week in the middle of my current tank of gas. Twice in vtec at WOT. Got 23 mpg. What happened? The MF'ers at the Honda place put my tires back at 33 psi all the way around.

 

i got 230miles on 3/4 of a tank most street driving drove till i had no bars on the gas gauge hnoes:

 

i get 23mpg. but im a nissan lol

 

ps. stop arguing and take a jager bomb

 

i do about 90 on the freeway and get 100 miles to the gallon.... thank you gas tornado! haha jk... i have a lead foot so my mileage is shitty

 

Well... Finally calculated.. displaced 10.79 gallons for 338.9 miles... = 31.41 MPG if my math is right.

08 Si Sedan stock with 3k+ miles, IMO ready for it's 1st oil change, though the dealer says wait until 4k.

I'll take it!!!! I haven't had a car with +30 mpg's since my 92 blue Isuzu Impulse.. don't laugh, that thing was a rocket and got close to 40 mpg. Cool little car too. Blue version of this one...

 

I was never asking you a ******* question you came out of no where and made a statement as if i didnt know that an intake increase airflow I mean wtf? THE PURPOSE OF ENGINE MODS ALMOST ENTIRELY is to create HP, they do this buy helping the engine breathe better. The more air the engine gets the more fuel is sent to burn with it thus creating more horsepower. I dont see what is so hard for you to understand?

 

Engine breathing better = MORE HORSEPOWER

 

The only statement to backup the an intake could increase mpg is that the current honda intake is causing stock cars to run rich

 

dude...just wow
It's 3:15 on the east coast so I'll let you investigate things on your own

 

More Fuel Burning Is More Fuel Burning Regardless, When You Increase Hp You Decrease Mileage

 

I think this is the most ignorant statement and blindness to the 100's of variables that can cause for an increase in hp.

Don't tell people information, straight up. And never come into something being so dam stubborn especially when you dont know what you're talking about. You come off really bad...

btw, fuel burning more effeciently means you're getting MORE out of it then you normally would. Means the same amount of fuel can give more power if x variable allows it to burn more effeciently.

i dont think i can put it any simpler.

 

I was responding on you saying to another guys post that intake increases mpg and then you contradict yourself somehow and try making a point which was an epic fail, I'm baffled and hope you dont give advice too often.

 

When was I contradicting myself?
All I said was an intake will not force but have a better airflow thus the engine will breath better. More fuel will be dumped into the engine but to correct running rich, the ECU will autoadjust the a/f ratio. Thus, the added fuel dumped into the engine will burn more efficiently. Engine Breathing better = good. Engine being forced to breath better = bad for mpg.
Get it now?

 

It wont adjust huge differences like Forced induction, of course everyone knows you need a tune for that but basic simple boltons still decrease MPG regardless of tune.

 

The ECU automatically adjusts air fuel ratios, thus the purpose of the intake is to increase horsepower by improving airflow. Increased horsepower comes from more fuel burning. More fuel burning = lower MPG.

I still dont understand why you guys attempted to tell me or correct me somehow. Im baffled at the response you guys gave.

 

More fuel burning EFFICIENTLY will cause an increase of MPG(by 1-3).
That's why people with F/I have low mpg. They need to constantly adjust the A/F ratio depending on the weather.

 

WTF are you guys drunk? Try reading my post again.

 

We already told you.
more clean air = more mpg
Why? intake will just increase by a little so no tune will be needed. Thus, there won't be alot of fuel burning. ECU will compensate for it.
Abundant clean air being sucked in = bad mpg
Why? F/I

 

When you don't know a basic intake gives you more airflow, that's when you should be worry about modding your car.
Not always will more air going in be good for your car.

 

Yup like example Forced induction brings in lots more air to burn fuel = more power but alot of people don't realize there needs to be correct A/F ratio with tuning.

 

Thanks captain obvious, not sure if that was a response and if it was what was the point?

 

intake gives you more airflow

 

:yeahthat:

 

Wouldn't an intake or anyother mod to unrestrict airflow decrease mpgs? I mean the more airflow the more fuel you use.

I know stock the max ive hit on the interstate was 35-36 mpg but that was 99.5% interstate, was a roadtrip and gas station was right off the side.

 

If you guys notice it, most young guys get low mpg while others who are 24+ get good mileage. That tells you alot, huh?
Driving Habits!

 

Ballin... tight... is there any difference in performance from the SI? other than it being a dope ass ballin ride... alls i know is that MUGEN means DOPE! im fairly new to the JDM, Honda, MUGEN, and things amongst that category

 

Yeah your pretty new to the import scene huh?

:word: thats true.

 

damn that'd be tight... Mugen-ness... i dont think id be able to keep up tho... damn LX

 

I drive chill trying to save gas too.

 

I live in Yorba Linda/Anahiem... not the hills.. .haha... but i spend most of my time in SA with work and friends... mostly work... I moved ouut to Anaheim about a year ago...


this isnt me, i found this and had to post this amazing video... the Integra noise is on cue and so funny... im lame
Supras with my mouth video

 

Oh was going to say if you still in Santa Ana you can roll with me.

 

^^^ Don't you live in Santa Ana

 

If I ever figure out how to post it I will
