im seriously thinking about selling my daily driver honda and just sticking with the fd...it's just so much more fun to drive and makes waking up to go to work tolerable. i commute 40 miles each way on the freeway and want to know what i can do to save gas. i already ordered a water injection kit which allows the use of 87 octane at stock boost levels. now i want to maximize my mpg. i've done all the standard tuneup stuff (plugs, filters, etc) and now i want to see what i can add or modify to get more miles per gallon. i don't care about performance on the freeway...im just doing a steady 65mph for about 40 miles. lets all share because im sure there are some guys out there that don't drive their fd as much as they'd like to because of high gas consumption and high gas prices.

 

Ok, the best way to do this is to take your car up 30 miles in a plane with a gallon of gas, and drive it out the back revving it like crazy until u hit the ground. Whaaa Laaaa 30mpg.

Now all kidding aside, stay off the boost as much as possible, and if I hadn't been at work and studdying for the past 26 hours I would think and type more but I'm shot. I'll chime in more tomorrow.

Whats the point of even owning an FD if you are going for gas milage? To make your dick bigger or something?

 

I am not sure you'll ever get 30 mpg unless you're on a very long trip and you drive very gently.

My record high is 21 in my FD and maybe close to 25 in my FC. My record low is 8 in the FD and 10 in the FC.

 

I've done 28, 29 mpg while cruising on a slow steady pace on the highway. 30 MPG would be an act of god. Maybe if you had someone towing the car?

 

You cannot get 30 mpg in an FD. The best you could ever hope for would be around 25, and that would be all freeway with no acceleration. You didn't buy the FD because it gets good mileage, and it never will.

Keeping your foot out of the throttle is all you can do ............ and most of us can't even do that

 

Don't think? C'mon Wargasm, you KNOW darn right that's IMPOSSIBLE. uselessid, you do realize that the AVERAGE mpg FDs get is TWELVE, right? 12. You're asking for close to triple that amount. You could dream about good mileage, and you'd STILL be off by 10 mpg or so lol.

Oh and I don't think getting a water injection kit to run 87 is a good idea...you do know that there are other things beside detonation to worry about w/ unclean fuels, right? Plus, unless you're a MASTER tuner, I dunno how you're gonna tune for WI. Steve Kahn, one of the BEST tuners, doesn't tune for WI cuz he knows how dangerous it is to do that. WI is used a a precaution against detonation, that's all.

I got 12.5mpg on ALL highway miles coming back from Miami to VA... Wargasm, that 21mpg wasn't just driving, was it? There was tuning involved, right??

As for me...I def. beat you in the record low. I actually got 5 mpg (average) once, when I filled up one night, when out joyriding (lots and LOTS of boosting) for a few hours, and had to fill up exactly 24 hours and 100 miles later...I kid you not (it coulda been 110 or 120 miles, TOPS)

 

No way, no how, hell no.

 

Buy a civic

 

get a geo metro man, acceleration is awesome too

 

he stated that his DD was a honda, civic maybe, but either way your right, he should just keep that. I have a dd civic and i luv that thing. 87 octane + 10 gallon tank+ 350 miles outta the tank = bliss (with exception of driving the rx-7)

 

Even a civic doesn't get 30mpg (city). Edmunds.com lists the 2005 Honda Civic LX 4dr Sedan (1.7L 4cyl 4A) as getting 29mpg city, 38mph highway.

 

Then he should get an insight. If he's not going for looks also..

 

Or a Moped...

 

Ooh ooh I got it! To get 30mpg in your FD do an engine swap...put a B16 into it or something...

 

maybe a fully stripped civic????

 

Or that Civic Hybrid. Freakin insane...it gets almost FIFTY MILES to the gallon. I bet those drivers don't even know what a gas station looks like...

 

Stick with the honda man, good car just not as fun.

 

I've gotten 27 mpg with 550/1680 injectors and keeping the rpms lower than 3000. Also with a 4.777 final gear which doesn't help gas mileage.

 

You're in Japan. That doesn't count. lol (don't ask me why )

 

The insight is the hybrid, it gets like 70. One of my high school teachers was drafting behind a tractor trailor for hours upstate. He calculated 104 mpg. INSANE.

 

rotary and efficient gas milage, thats funny! the answer to your question is you cant.

 

The EPA mileage stated for the 93-95's was 17 city / 25 highway. I usually see 14-17mpg, my car is basically stock. Best mileage ever was 19mpg on a long freeway trip, 100 miles there 100 miles back, no stops except for the destination.


Buy an RX-8 and drive it like a grandma, that's probably the best mileage you'll ever see out of a rotary. City Mileage: 18 mpg Hwy Mileage: 24 mpg according to edmunds.com

That sounds familiar....isn't that what the sticker said on the FD? TOTAL BS. Unless there's some magical method the Japs use when driving...

 

that's EPA claimed mileage, using their tests. Look it up to be sure, but I've heard it's 55mph constant speed for the highway portion, and something equally easy for the city portion.

It's probably safe to assume that most companies send a "ringer" for the test: a car hand-built and tuned to the optimum factory specs for the test.



You should see a slight improvement in mpg by inflating the tires to higher pressure, try that it's cheap.
