Fresh plugs, wires, cap, rotor, oil/filter & air filter will do wonders for increasing mileage!

Another simple way to increase mpg that seems to elude most people is coasting! When a stop light ahead is red, or you are approaching a stop sign, why not coast to it, insteading of keeping the throttle depressed until you hit the brakes? I observe far too many drivers zooming past me while the light ahead is red only to slam on their brakes at the end. I can only imagine how much fuel is wasted doing this.

you guys getting the low mileage what size rim and tires? on my other car i slapped some different rims and it threw off my speedo as i use my navi to determine my speed. my speedo was about 5 miles off goin 60, i think this makes a slight difference. though it is sohc civic i avg 33 mpg about 2k after a oil change.
lol i havnt gotten through my first tank yet on my celi

also when you fill up at the gas station put the number of miles you drove divided by the amount of gallons that was put in. that should give you the mpg

bringing a dead thread back to life

my 3S-GE gets proximately 21mpg.
and thats way too much, when a gallon of 95-octane costs about 4,5€ and thats over 5 $.

i should be driving on 98 or 99+ (shells V-power) but really cant afford it

Consider driving at 65mph instead of +75 (which is considered slow here in CA). Also tail other cars like SUVs, trucks, and vans. Was watching Myth Busters the other day and you can increase your fuel efficiency by up to 35% depending how close you tail another car. I'm NOT saying you to follow 10 feet behind someone else, but instead of being the leader of every pack, consider being a follower instead. Even following 50 feet behind another car can reduce drag and save you ~5-10% on gas.

My drive up from LA to SF, I made it on one tank (400 miles) by tailing behind RVs and semis and going ~70mph. On the way down from SF to LA, I was rushing fast (+80mph) and I had to refill at 330. So yeah, it does make a big difference how fast you're going on the highway.

Plus I shift to neutral when going down steep hills (is this bad? idk ) and shift to neutral on red lights. It seems to help a tiny bit too. BTW, I'm on an auto 97 ST. Heh, doing this might not save me some gas, but it still makes me pick up more speed than simply coasting in gear...so idk

actually, your better off letting your foot off the gas, and coasting in gear.
anytime your above 1500rpm, in gear, and not on the gas, there is NO fuel being injected.
coasting in neutral down a hill or to a stop your wasting more fuel (because your using fuel at idle) than coasting in gear.

^ thats helpful

Ok i have read this thread and yea i get about 22 mpg on stock 1.8l 89 octane 17" rims and auto 161K on egine:( the only thing is i want to put on new plugs cap and rotor and see how much i get do any of u guys have recommendations cause i already know that alot of the people here are running NGK plugs so ill look into that any suggestions help

Jeez, how are you people on 7afe's getting such bad mileage 0_o. My 3S-GE gets around 25mpg and that's about 60-70% city driving, get around 570km/360miles from a tank and I shift between 3 and 4.5 most of the time.

>

Let your grandma drive!!!!!!!!!

>
thats impossible, my 3S-GE will not go over 450km on one fill

But what kind of gasoline do you guys have there in the states?! 89-octane?! Our lowest octane level of gasoline is 95-octane..

Replace your plugs, wires, cap, rotor and air filter. Unless you are lead-footed and are accelerating hard from each stop, there is absolutely no reason you should only be getting 22mph on a 1.8. I'm not so lead-footed but I'm no granny either, and I'm averaging 28mpg this winter with about 75% of my driving in stop-and-go traffic. Tires are 215-40R17s with 226k on the body and about 100k on the engine. Intake and everything are stock, running on 87 octane (regular unleaded) with I think it's 10% ethanol (mileage-reducing ) for the winter (required in our state).

IN the states most cars use 87... then there is 89 and 93. 93 is usually the highest you find at a gas station unless your near a race track where you can find 100 octane if your lucky

Best way EVER to save on gas....Dont Drive! lol or limit how much you drive. I used to take the bus downtown to work almost everyday and it saved me ALOT on gas and parking

best way to go.. carpool :]

Keep your tires overinflated, tires should not wear weird with their construction, I drive my WRX with the tires around 36-38 psi(max tires pressures are usually around 40+ psi). Just have to keep and eye on thread wear.

Coasting to stop and downhill should will also improve overall MPG...I do it all the time.

THANK U!!! i always use to shift in neutral too and thought i was saving gas.....

>

Doesn't leaving the car in gear while coasting put unnecessary stress on the tranny?

>
no.
read your owners manual.
it actually TELLS you to drive this way.

And come on guys, the sound when you got ~4k rpm and coasting, its sensational <3

woot woot yes its worth it hearing the sound and feeling instead of gas mileage

the main difference I see is if I drive economically I get about 8.5 litres per 100km city and If I have a heavy foot I get up to 10.5 litres per 100km, freeway I get under 8 litres per 100km.

Ive been doing some experimenting on my car and the best i have come up with is 28.5 mpg. This is a mix of street and highway. I achieved this by driving 60 mph on the highway, it is really slow but i get decent mpg. on the street the car has no problem but once you drive 70mph gas just burns like no other.

My suggestion:

Drive 60-65mph, and set your **** on cruise control cause that **** does wonders!!!! werd

wow i didnt think it was the case but i did some googling and bam! it hit me source from popularmechanic q&a on a google search so it cant be wrong right? lol



Q: I have a question about fuel economy. If you are driving downhill, do you save gas by putting your transmission in Neutral and coasting, instead of having your vehicle in Drive? I think that you do but my wife seems to disagree. Can you give me the correct answer, so I can tell her that I’m “Mr. Right,” as usual?

A: That depends. The engine isn’t braking the car going downhill if the transmission is in Neutral, so economy would seem to be high. But if you think the engine is still using fuel while coasting downhill in gear, you’re laboring under a misconception. Most fuel-injected cars turn the fuel delivery completely off when you lift your foot from the accelerator. They still burn fuel when idling in Neutral, so do the math. The amount of fuel burned at idle over, say, a couple of miles of coasting downhill is small, but it’s still more than zero. So if you’re driving a modern fuel-injected car, you’re wrong.

Older, carbureted cars would suck gas through the engine while coasting in gear, even if you turned off the ignition switch. In this case you’d be right.

i get close to 400 every tank!

I get around 400 when I hit empty, but I've been told I drive like a granny.

I drove my car to 425 miles on 13.2 gallons. Thats about 32MPG. I've gotten up to 35. I'm going NC on Friday, and that's like an 800 mile drive. I'll tell you what I get going down there. I'm shooting for 36+.

Also, I'm pretty sure our gas tanks are 15.9 gallons...

just a fyi your in ca. Our fuel has more ethanal then other states so our MPG will suffer.
