I have a bone stock 97 civic that I managed 44 mpg out of on this last tank. It's been a combination of city and highway driving. I never exceeded 60mph at any time. I'm looking for ways to get it closer to 50mpg. I've considered going to 5w-20 on the next oil change instead of the 5w-30 that I'm running now. Might help me pick up 1 or 2 mpg. Anyone have any other suggestions?

5w-20 to me seems fairly low...but are you using maximum grade/octane gas? Also, keeping your speed under control is a great start, assuming it's a 5 speed, what are you shifting at? If you hit it generally at 3,500 to 4,200 and only putting the pedal about half way down to go, it should save some too, that's just some things in my experience that save me more gas.

Most if not all Ford gasoline vehicle run 5w20 but i dont know about honda though

A new TSB about a year or two ago stated that recommended for most hondas was 5W20.

I'm not sure what I'm shifting at because I have have CX which has no tach in it. I noticed that my front tires were a touch on the soft side. Inflating them a bit more should decrease rolling resistance a bit. So between 5w-20, and airing up the tires, anyone have any other suggestions? Do you think that there's much to be gained by lightening the car any?

lol love what youre doing..keep it going. im curious to see if the 50 mpg is possible. goodluck

sorry to thread jack, but I usually floor it up to about 3000-3500 then shift. Would it be better to rev it higher to about 3500-4500, but only have the pedal half down? Would I get better gas millage?

Well, gas milage is largely determined by throttle position more then revs (VTEC excluded)

i drove my car pretty "laid back" and i always could get about 40-41 with i/h/e

xonn

so you don't think that reducing the weight will really make a difference? I'm looking for some HX wheels as I've heard they're 12lbs. That'd be a 6lb savings at each corner over the steelies i'm running now

turnsignalandy

get vx rims, their like 9 pounds. Ya weight reduction would improve gas millage, but your cars probably already pretty stripped from the factory. How do you plan to reduce weight?

I managed to get 37 mpg out of my 2000 EX with 17" rims with some 215 tires And this was going over the pass out of LA on the 5, granted after that it was nothing but flats.

When I had my old stock wheels I managed to get 42 mpg driving back from Mendicino CA (windey hilly roads) It really is all about throttle position

xonn

I'm not familiar with the VX rims. Are they 14 inch in size? where can I get them? In was considering perhaps a CF hood. That'd knock another 15 - 20 off the car... Still debating though. They're pretty expensive and can make your car a target for theft.

i managed to get 49.** mpg out of my cx back when it was stock. i shifted at 1.5k rpms all around town and never went over 40 mph(1.5k rpms). not many people believe me but i had two witnesses.

turnsignalandy

vx rims are desinged like hx rims but they are 13s

EG2Driver

keep in mind if you shift too soon, u'll need to press down the gas pedal more. Streamline your car by having a underbody diffuser and wax it, keep the windows up as well.

Definaltly try to get a hold of VX wheels. Don't go CF hood....why spend 400 bucks to save 20cents per tank?

Syndacate

Get a lightweight flywheel, less rotational mass on the crank frees up a lot of HP, should make things easier on the engine (less throttle needed).

JDMFantasy2k

i got 35mpg out of a 2000 civic ex with a custom turbo kit and still ran 14's


I bet if you had one of those ricey air diffusers in the rear bumber that it would probably help evacuate trapped air in the bumper. Also stripping the car of weight will help too.

Jhonny Ricer

Take out your ac maybe ive heard it actually does help somewhat even though during the summer months it could get a little brutal but ehh thats what windows roll down for
not to mention doin this frees up a couple lbs also if you really wanna cut some weight

squarepusher

i KNOW your not trying to rub this in based on my other thread ...

xonn

does anyone make one that actually fits the rear bumper properly and looks like a factory piece?

keep in mind with smaller and lighter rims, you have to get HEAVIER TIRES. i also agree with syndicate on the the lightening the rotational mass (flywheel, crankpulley, rims/tires) those things would def make the engine's job easier. some other things that would get you better gas milage is an intake with good air filter, header, high-flow cat, cat back exhaust with manderal bends.

also do you down shift when slowing the vehicle, or are you one of those people who put the car in neutral and rely on the brakes to completely slow the car? I am pretty sure that when you down shift instead of putting the car in neutral you get better gas milage. This is because the fuel injectors completely shut down, however, when you put the car in neutral the injectors must inject enough fuel to keep the engine idiling. Sorry if that does not make sense, its hard to explain

one more question, do you live in an area with a lot of hills, or is it pretty flat land where you live?

Agreeing with this; I think it's been established that keeping it in gear but giving no throttle uses a miniscule amount of gas (or none at all, I'm just playing it safe since I can't remember 100%) compared to putting it straight into neutral, as the car will need gas to idle while in neutral.
