running car till im out of petrol?

[Mugen_Euro]

Hey guys My cars been getting bad mileage since i bought it, 350-400km out of a tank but i fill up when the fuel indicator goes on. Ive herd form some people that the indicator on some cars go on premeturely and by running the car till its empty the fuel meter will reset?

I dont plan on doing this more than once, but i think its worth a shot incase my car can actualy make 500+ km out of a tank.
i have a full 10 littre jerry can in the back for when i do run out but my question is will this cause any serious problems for my car, i know its not good but can it be done once at least or is this just stupid ><

will vapourize cause condensation which means moisture into left over fuel into your fuel system, water doesnt' have lubricants like oil does,,, petrol is a form of oil

moisture into fuel system will destroy seals, injectors, fuel filters, and longlivity on your motor

[Red_EG4]

Just throwing an alternative solution out there.
find out what capacity your tank is, when your fuel indicator comes on fill up and note how many litres it takes.
That way you know how many litres you have left when the light is coming on.

Carsales.com says the tank is 65 litters and i generaly fill 50 so roughly 15litters left in the tank then... when should the indicator come on normaly?

[na-118]

i wouldnt recommened it

[Urabunchamupets]

Have you had your car serviced and checked your tire pressures recently?

[Mugen_Euro]

Have you had your car serviced and checked your tire pressures recently?
Yes and yes. I also run a shitty piggyback (vafc2) and when it was tuned the bloke said the fuelling was spot on... but judging form what i figured pout before i have another 15 litters left in my tank which should mean id get around or over 500 km per tank which is decent....
now i just want to know how to reset the fuel gauge and when it is normally supposed to come on

[charliebrown]

Phwoah bro you're getting 12.5-14L/100km on an 04 model euro? Somethings up...

[Mugen_Euro]

Phwoah bro you're getting 12.5-14L/100km on an 04 model euro? Somethings up...

yer i figured... butt if their is another 15 litters in my tank u know... maybe id be getting a bit better.

Anyone own a 03-04 euro and know roughly when the low fuel light comes on?

[jeffreymui]

mind u back in the days in my is200 when the light pops up, i'll still have 20l left in the tank so i think its kinda normal? my is200 has a 70l tank

[Mugen_Euro]

mind u back in the days in my is200 when the light pops up, i'll still have 20l left in the tank so i think its kinda normal? my is200 has a 70l tank

wowww thats ridiculous man.... nah id liek the light to pop on when im at 60 litters and have the last 5 to play with to get to a servo or sumthing... but if its poping up at around 50 litters in im gettin cut 15 and gona be worrying about when its gona run out

[dougie_504]

5 litres means you have about 40km to find a servo mate. Better off with the 15L so you have 100km+ IMO. Just fill up when the light comes on...

[Mugen_Euro]

hahaha 40km where i live is plenty to find a servo generaly ill find one every 3-5km as i usualy go to the same places... id much ratehr it come on when i have 5 litters reserved

[charliebrown]

My tanks 50L, my light comes on about 35L... that's 15L as well, you're not alone :P

[Mugen_Euro]

My tanks 50L, my light comes on about 35L... that's 15L as well, you're not alone :P

hahah how much u get outa a tank/ what car u driving

[charliebrown]

Integra DC4. I get 10L/100km granny driving, 11-12 when i let revs go above 3k. I drive an auto

[Mugen_Euro]

yer im driving an auto too... i like to give my car a bit of a thrash in fist gear tho.... redline it a bit coz im a wanka so im not surprised i dnt pull higher numebrs but if i cant get 500+ ish outa 60 litters theirs defs something wrong cos i have mates that thrash their car all the time and get better milage :(

[NightKids]

Why df would you redline your first gear all the time in your Auto Euro? That's just hoon/wanka behaviour! No wonder u get crap fuel economy...

[jeremydawg]

Who wouldnt? its got the K24 man! lawl

[Indie]

Why df would you redline your first gear all the time in your Auto Euro? That's just hoon/wanka behaviour! No wonder u get crap fuel economy...I almost said it, but then couldn't even be bothered replying. I mean really, anybody who forces their Accord to take off like that isn't entitled to have any complaints about fuel economy, or tyre wear.

Maybe just trying driving sedately for a week and see what happens? It'll drive you f'ing nuts because I did it once (and my thermostat shat itself that week and ruined my fuel eco anyway) but would be interesting to see what you can manage.

guys i said it before i drive like a wanka sumtiems.. . not all the time but a fair bit. However i have done a week with driving granny like (shifting before 3k) i got 450km outa tank as i rememebr so my economy wasnt much better IMO. Id rather enjoy my car and get 50 less km. that being said i have 2 mates one with a mazda 6 (auto) one with a sp23 (manual) who both hoon / drive like wanakas all the time everytime and still manage 550+ out of a tank. Im sure theirs alota people on ozhona who drive their cars harder than me and still manage 550+

Just to keep you up to dat im sitting on 460km atm out of this tank and the fuel light came on at 380. Fingers crossed... i might make it to 550 :)

[Mugen_Euro]

Update: car died today at 480km. Parked at mod project and when i went to leave it wouldnt start up again. Filled it up at the servo with 63 litters.

so roughly 480km out 65 litters = 13.5l/100km = shit economy :(

[Lucid]

hmmmm i generally get 600 k's to a tank, 95-98 Premium, Yesterday i got to the fuel indicator at about 603 k's didnt want to risk it anymore so filled up at about 620.

One week i didn't hit vtec at all and got it to 680 k's

[Urabunchamupets]

combined fuel economy for an Accord Euro is 9.1l/100km. So if your doing alot of stop start driving that figure sounds about right. Are you carrying much excess weight? Big chrome wheels, subs, amps?? Also, what fuel are you using? If your using an ethanol blend you probably wont get as good economy either

[Mugen_Euro]

i got 2 18inch wheel but they are roughly the same wieght if not lighter than my stock 16's on the front and yes i have 2 12"kickers + amp in the boot but the subs + amp wiegh abot 20kg tops doesnt reely wiegh the car down at all. other than that i have ct headers, a tuned vafc2 and thats it.

tires are pumped to correct pressure, new airfilter, new oil, new oil filter, tuned the vafc last year november. I cant understand why my cars so bad on fuel.
I do do a fair amount of resedential driving, short trips to my friends houses and stuff but i do a bit of hyway driving too to get to work....

[drsilliez]

running ur car til empty?....and at the same time suck up all the particles and crap at the bottom of your fuel tank.... (Y) lol

[drsilliez]

^^ hence its not good i heard....

[Mugen_Euro]

^^ hence its not good i heard....

I already knew that.... but i was curious so i experimented. haha

[Mikecivic78]

I filled up my EM1 today (45L tank capacity).

I filled up just as the light came on, it took 37.22L. That means the light came on with around 8L in the tank. For a bB16a anyway, seems on the money.

Worked out 9.34L per 100km. Pretty good since the car sees 8,400 RPM a bit.

Anyway, NEVER let it run empty, you'll dig up all the crap at the bottom. The older the car, the worse this can be. It'll clog your fuel filter and can pollute your fuel injectors.

[white_ep3_civic]

I had a sound system (sub, amp), 20" rims and a tune and I got 550-600 and that wasn't driving granny spec all the time. I'd go get that checked out. Mine was manual but it shouldn't affect the K's/tank that much.

[gumus89]

The fuel system takes its fuel from the bottom of the tank anyways people. Id be more worried about the possibility of water from the top of the fuel getting to the bottom. And thats not likely.

Anyways, your fuel economy is horrible.
Can people stop being retarted when talking about fuel economy please. Its not that ****ing hard to reset your trip meter, drive, fill up and note how many litres and just work out how many litres you get per hundred k's.

(litres)/(how many hundreds of kays)

So 50 Litres in 500 kms is 50/5 = 10L/100kms
50 litres and 5 hundred kms.

I have an average of 8.5L/100kms in my manual BB6. And thats with only suburban and peak hour traffic in Adelaide.

It is possibly because of the VAFC2. If you tuned it to get more power, then it is most probably been set to increase the injector cycle. The problem with VAFC2 is that it is a coarse fuel adjustment tool. You get only a 12 point fuel curve adjustment per low/high cam and only 2 throttle setting banks (partial throttle and full throttle). There is no fine high resolution map which changes the fuel adjustment setting for every 500rpm and for every 5-10% of throttle opening.

To be honest im super noo bwhen i t comes to the vafc but the tuner said it was almost impossible to reajust the fueling on the car because the computer would reajust to factory fuel settings by itself or something... either way he said the fueling was spot on already.
Ive been reading up and im thinking maybe i shuld be looking at a new 02 sensor?
ive realised that the car tends to smell quite bad after i drive it especialy if i drive it hard... smells like rotten something as well as and i dont know if this is relevent but my car is able to read the outside temprature and today id say it was about 12 degrees celcius outside tops, but the meter said it was 22 degrees...
and ideas?

[itachi-kun]

It could be the O2 sensor, my friends ep3 was getting 350km per tank which is pretty bad compared to when he first had it. Not long after his engine light lit up and had it check and it was O2 sensor and his fuel economy has gone back to what it was originally.

but my engine light hasnt come on... :(

[dougie_504]

'94 EH9 D16Y1. My fuel light started coming on the other day (when you're going uphill etc, then off again) and I filled up 40L of a 45L tank. So it looks like my fuel light comes on when I have about 5L left.

I managed 533.5km from that 40L, which is awesome for me, but this was mostly because I had to do a 300km round-trip out to the country town where I went skydiving, and on the way home I managed to sit in the slipstream of a Ford Territory for about 100km :D

Normally get about 450km before the light comes on :(

thats better than me bro :(

[kural7]

hey i own an 05 accord euro and if i drive sensibly with the pod filter off i will hit atleast 480 before my light comes on. also what fuel do you use? 98 or normal unleaded. i have a mate same car same mods he uses 91 and only gets 380-400 before his light flicks on. either your fuel filter is on the way, your using cheap fuel. DONT let the fuel run empty also might want to try FUEL injector cleaner i seemed to get an extra 20k's after using that but its hard to decide depends on how often your letting your VTEC kick in :P mine is almost every gear :( and i still get atleast 450.

hmmm thats sum good imput bro. Ye im using 91 atm... ive tried 95 and it made no difference tbh. i got an extra 30km out of the tank for an extra 10 bucks.... but ill give it another shot

[iLlusion10]

You shoudln't be using RON91...if you look at the fuel cap it says MIN RON95 for a reason. That could be your main reason. But it sounds strange I've got an auto euro and getting 550+km out of a tank even under hard driving.

Hmmm i havent heard about 91 opposed to 95 impairing fuel efficency by that much tho... i know i should be using 95 but scince i didnt find a great difference in performance and the slightest difference in km/10L i figured id stick with 91.
Oh and that was actualy 98 v-power not 95

[kural7]

it really comes down to the servo you use aswell.. try alternating between good servos. my mate owned a servo with no ethanol rating in there fuel. gets you thats extra kick you need. once again just try 98 put some fuel injector cleaner and try your luck, if not try the 02 sensors or your fuel filter.
good luck keep us updated.

[charliebrown]

Hey mate, i just got 13.2L/100km. Feel better? :)

[Mugen_Euro]

Hey mate, i just got 13.2L/100km. Feel better? :)

HAHAHA good to know im not alone champ :D but feel sorry for ya at the same time....

to keep you giuys updated im gona fill up with v-power (98) and use a full bottle of injector cleaner i picked up form supercheap auto. fingers crossed it does something haha, but i may have to run 98 for a couple of weeks to see a improvement....

[charliebrown]

hey let us know how the injector cleaner goes. i havent tried it before and am considering.

ive just changed from v-power to BP ultimate so ill observe if changing fuels actually does anything substantial for economy

[4age8u]

my bmw 318i e36 has a 65 litre tank....get 500kms from it and its a 1.8..so for a 2.4 i dont think yours is that bad

[Mugen_Euro]

my bmw 318i e36 has a 65 litre tank....get 500kms from it and its a 1.8..so for a 2.4 i dont think yours is that bad
do you get 500 from all 65 litters or from abouyt 50 - 55?
and you car is a fair bit older, im assuming this, but i do believe the accord euro is a more fuel efficeient car?
And my mate has the hatch version of that car im prety sure... he gets 600km from about 55L i think....

Update on injector cleaner. Im running 55 litters of 98 and about 10litters of 91 that was in the tank already and a full bottle of injector cleaner, i must say im dissapointed with its performance. Car feels more sluggish than before :(

[charliebrown]

My mechanic said he'll chuck in injector cleaner when he does my next service so i dont need to. Shouldn't use it too often or something

[white_ep3_civic]

If you keep using 95-98RON like you are supposed to you will notice fuel consumption start getting better. In my euro I only ever went to the one servo and only ever used v-power. I'm pretty sure you can damage things if you use 91RON that's what I have heard anyway

[charliebrown]

mugen_euro, whens your next service? get all your shit checked up/replaced. you should get the best fuel economy straight after so on your first tank after go for 98RON and granny it?

[white_ep3_civic]

You have to let your car get used to the petrol

[Mugen_Euro]

Yer i was thinking it might take a couple more weeks till i see some real results. As for my service, i had a minor one oil change + filter and air filter trany fluid etc...and i recently replaced my air filter, oil filter and oil when melbourne had the floods. Im thinking ill probably do a major service sometime soon because this fuel economy is killin me :(

[Mikecivic78]

Change your fuel filter. Seriously, it's a very basic DIY, why pay someone to do it? Even if it doesn't fix the problem, it'll narrow the problem down.

There are many things that can kill economy. Cactused thermostat, fouled injectors, fouled PCV can also contribute. Fuel filter would be my first port of call.

And stick to 98 octane fuel. I recommend BP or Mobil, I'm not a fan of Shell. BP Ultimate is best IMO.

[azn_k3nt]

Get a major service from honda, done? but definitely anything above 10lt/100km on an accord euro sounds wrong unless your red-lining...

[Mugen_Euro]

I have a feeling it might be the thermostat... but ill look into the fuel filter.

Update, im still on my first tank of 98 and ive run about 170km and its sitting at just under 3/4 tank atm. Ive redlined it only once this whole week adn that was only in first gear to 70. other than that ive been keeping my shifts to at or below 3k revs.

[charliebrown]

LOL WUT first gear to 70 in an auto? that even possible? :P

[Mugen_Euro]

hahah hits about 75-78 before the limiter cuts in in my car? im pretty sure thats standard for the auto version - drive it in that semi-auto shit just for shits n giggles

[charliebrown]

what the fakk... I GOTTA TRY THIS. do you just plant your foot all the way down from a stop start til it cuts out? mine always shifts at like 20km/h lol

[kural7]

im assuming there is a triptonic feature where you can shift the gears manually? like normal automatic cars? correct me if im wrong.

[Mugen_Euro]

Haha yer. its that tiptronic thing. Its in all of the auto euros. Even in standard auto, if i floor the pedal it will go to line and then change gears, i still manage about 70 - 75 in first, i can push it a little higher though because of my tune but i generally dont.

[Mugen_Euro]

Just an idea guys. Culd my problem be the MAF sensor?

[charliebrown]

Wheel balancing + alignment can contribute to fuel economy? ive got hard pull on my steering wheel atm, gonna go call up tyre place tomorrow then fill up and calculate economy on next tank.

No, it makes little, if any difference.

Done that thermostat yet charlie?

[charliebrown]

^ nah mang, i just start up my car in the mornings then go change and get ready. by the time i leave the house it's been 10-15 mins and cars warmed up. needle bout 1/3 way up. dont think its an issue anymore. still getting same fuel economy lol

[Mikecivic78]

Dude, why haven't u done it? 10-15min to warm up, WTF? You don't need to warm up a fuel injected car. You thermostat is ****ed FFS.

[charliebrown]

My first gear only goes up to 60 ish and redline limiter kicks in :( your euro is boss

Thermostat is deff gone, its stuck open and feeding coolant constantly. This is bad for fuel economy and do you find that your temp guage drops when you are travelling at speed i.e on the highway?

[Mikecivic78]

Since I switched I've noticed slightly better mileage and less carbon build up at the tailpipe. Some other peeps have said they don't recommend it too. I'm sure v-power isn't that much worse though.

ive run v-power in mine since day 1 as did the previous owner. I get some carbon build up on the rear bumper. I drive like a granny 95% of the time (had to survive 1 year on 1point) so when I do put my foot down it blows a bit of carbon. You are the not the first person to tell me they are getting better mileage with BP

What oil you running mike

[charliebrown]

I've used both BP ultimate and V-power and i get better mileage on vpower. Usually get 200-220 when needle hits halfway. BP hits at 170ish

Im getting about 300/tank atm but I know my car is running rich.

Back in the day when I had my EK1 I used to run Vortex 95, never got less than 500km/tank...ahh I miss those days

Wow, that's shocking economy. I get no less than 400, and thats with plenty of Vtec runs and shifting at 4-5K rpm.

I use Nulon Fully Synth 10w40. Good bang 4 buck oil.

[newbi-ek]

Hey man, I have the same prob, full tank with 45 liters but fuel gauge looks pretty empty after 350 kms but when I filled in petrol, it only takes 25 liters to fill it up...

[kural7]

ei guys hoping some1 can help me with a slightly unrelated topic. my car is on 200k milage and it burns oil pretty quickly. every 2-3k the oil dipstick reads low and i keep topping up till about 6k then i service it. just wondering if any1 knows about the additive that is meant to be aded to the oil which is meant to make it a bit thicker and clean out the inside a little. do those products actually work?

[newbi-ek]

hey man, have you checked your engine internals? like oil control rings and such, im not very good at this but i do recommend u check it at your local mechanic.. cant help much but gd luck mate

[gumus89]

There are a number of ways you can burn oil. Your piston rings could be worn, letting some slip into the combustion chamber and getting burnt or it going through your pcv valve into your intake manifold. You could also be leaking it from a number of places such as oil filter seal or main seals. Get someone to look at it.

[Mugen_Euro]

Hey man, I have the same prob, full tank with 45 liters but fuel gauge looks pretty empty after 350 kms but when I filled in petrol, it only takes 25 liters to fill it up...

mate that means u got 20 litters in ur reserve probs needa reset ur ecu or sumthing to gte it to recalibrate, but ur cars running great if ur gettin 350 outa 25 litters

[charliebrown]

found your problem yet mugen euro?

[Mugen_Euro]

Anyway guys a update: ive been running V-power (shell 98) for 2 weeks now and im averageing about 430km outa 55 litters and i only tooke the revs passed 5k about 5- 10 times every week, and thats only in first or second. Generaly im shifting around 2.8-3.2k revs

soo not lookin great

[charliebrown]

take it to a shop or somethin and get everything checked? or have you already done that

[Mugen_Euro]

running real tight on money + owe my rents money for permits n hsit for uni :(
im tryna save up, and im gona gte it compression tested coz it locked up in the floods but i gota borrow money of my rents fro that too....
might take it into honda and get em to run a dyagnostic an c if it throws an codes but untill then....

[Mugen_Euro]

im thinkin the problems an oxy sensor or possibly the MAF sensor but duno yet...
