EP3 type R fuel tank

[simmbr]

Hey Guys

Just a quick one. One of my mates is looking at buying an EP3 type R, and was wondering what size the fuel tank was? We have checked everywhere on the internet, and was wondering if anyone who had the car would know, or just anyone in general. And also, if an owner can tell me average fuel consumption of "normal driving", not conservative driving. You know, the occasional fang every now and then.

Thanks guys

The EP3 fuel tank is 45L and i'm getting around 470-500km until the light goes on with normal driving. But even with punching it every now and then I get more than 400km.

[Mugen_B16B]

yeah i get around 500-600 highway, 400-500 vtecing

tank is actually 50L mate :)

i do alot of city driving and i usually get 450-500 on 98oc and im a lil bit of a heavy footer

[mp-]

that works out on average roughly to be 7-8L/100kms?

i would have thought it would drink a lot less.

[mp-]

i was wondering, if ur cruising at 110km on the highway/freeway. Roughly wat rpm would you be sitting on?

[typercivic]

Definitely a 50 litre tank, when i had the car i used to get about 440km until the light came on with mostly city driving and the odd freeway trip but it was driven pretty hard.

At a 100km/h it was about 3400rpm from memory so 110km/h would be just under 4K i think but I am sure someone who still has their car will be able to give you a more definitive answer.

[bradb16a]

best KM from a tank 634km highway normal average 520 - 540

[mp-]

wow, cruising at 100-110 km to b almost 4k rpms? thats damn high. cause ill be mainly driving on the M4 during non peak hr times or going the opposite way from the chaotic jams the M4 usually has.

If cruising at those revs. wouldnt it drink heaps on the freeway/motor way? cause of the constant high revs?

High fuel consumption is actually due to how heavily your accelerating not the amount or RPM's your pulling. Foot off the accelerator pulling 3000rpm for example uses almost no fuel.

Strange but true.

[SuperSteve]

i drove to yass last 2 weekends ago and when i got up to 4krpm when i was on 120km/hr

[PeppeX]

Sorry to bring this back up. I have only ever done 420km max (usually just hitting 400km) before the light comes on. Just out curiosity do all you guys have a intake is that why u are getting better fuel economy? I only have mugen twinloop other than that everything is stock.

[RPS.13]

I only have a cat back, and now a 3A racing pod in the OEM airbox... averaging 550-600 per tank. Moderate vtecing, 80% freeway km's.
Was previously running a trust replacement filter and also a pipercross one, which still averaged 550-600 a tank. My light normally comes on at 540-560.

What is your driving style like? and what areas/roads are driven on?

[PeppeX]

I'm not heavy on the throttle or anything. I even let the car roll slowing to the lights when its red hoping it will turn green so i can increase fuel economy.

Never even been on more than 90km zone in my EP3. Mainly on 60km/hr roads, usually in 5th and 6th if road is straight and flat.

[DR HONDA]

I reach approx 450-480k per tank with very sedate driving

[RPS.13]

I don't think your fuel enconomy is too far off. I recall when I was living with my gf closer to my work, which was a 9km round trip, also driving into the CBD some days which is a 18km round trip. All 60km driving I recall getting approx 440-460 a tank. Some days driven during tail end of peak traffic. Minimal Vtec.

[bennjamin]

perhaps since the ep3 is tuned on a higher RON - using our 98 or worse makes
The can run richer and thus more fuel used ?!
Just a theory !

[bigbaby0223]

I usually get 460-500k a tank. Only let the vtec comes in maybe 2-3 times per tank. So I guess it's not too bad.

[vishta]

Mine is about 450-500k/ 98 RON tank mainly driving on 60 / 70k roads ... vtecing sometimes
and I found that using Caltex fuel isn't as fuel efficient as V-Power or Mobil (7-11) fuel

[flubbar]

I found that using Caltex fuel isn't as fuel efficient as V-Power or Mobil (7-11) fuel

funny, quite the opposite for me. V-power for me burns much more quickly than vortex 98. best results with bp ult.
i normally get around 450-500km before light comes on. i normally shift around 4k rpms, esp in 1st gear but once i hit 60km i drop it straight into 6th, unless i'm in a hurry. vtec a few times a week.

[JohnO]

guys i use to get like 370-90 before light comes on, this was before mods though, just after changing filter and complete flush after getting 270km max when i just drove for a week from dealers. Now with the gruppe m and rm01a my tank gets to 340, light comes on but this is with short distance driving <10min trip each way to/from station for the weekdays. When im filling up just as the light comes on max it'll do is 33-35litres, recently had to get another o2 sensor replaced hoping the new one be more efficient in controlling my fuel eco. Hardly vtecing it and im keeping revs between 2.5-3.

[twelve]

mine isnt to bad, i get under 400 but vtec all the time.
Exhaust and intake on mine

[Poeter]

It comes down to what viscosity you're using with your engine oil and your driving style.

The higher viscosity the higher the fuel consumption will be but will offer better protection for the engine.

Driving style varies from person to person. Having an intake doesn't necessarily mean you'll get better fuel economy. To some people it's worse because they may be more heavy footed to achieve the intake growl.

400 before the light turns on sounds ok to me. Most importantly you should do the maths. Work out your L per 100km ratio by finding out how much it needs to filled for a full tank and how many kms you drove.

if you achieving below 10L per 100km then you're doing ok with fuel.

For your reference, I think Fn2 does about 9.5L/100km from what Honda marketing claims. So if you're close to that value then you don't need worry. But if you're achieving 11 or more with normal driving then I would look into the issue more further then.

[JohnO]

using 10-40 for oil, since im reaching 340 now and the light comes on, refuelling to say 35litres: 340/35 gets me 9.7l/100?

[bennjamin]

you should be only using 10/40 oil on the racetrack or for summer. Any other time , IMO , use 5/30 or 10/30w ( thinner at operating temp. than 10/40w)

[PeppeX]

using 10-40 for oil, since im reaching 340 now and the light comes on, refuelling to say 35litres: 340/35 gets me 9.7l/100?

Ur getting 9.7km per L not 9.7L/100km

So u can drive 97km with 10L of fuel

I am averaging around 10.1km/100km. I guess its not too bad.

[Poeter]

Yea then your fuel economy is not bad at all. Just for some reason you fuel light is coming on too early or your fuel gauge has on uncalibrated.

[PeppeX]

Yeah my fuel needle doesnt move from full until i hit around 110km. The first half of the tank usually goes 250km and second half goes around 150km. Is it easy to recalibrate the fuel gauge?

[JohnO]

Thanks for the response guys, Ben what oil are you currently using for the winter season? 10-30?

[stienerv2]

Which brand sells 10-30 full synthetic? Im gonna try penrite 5-30 next and see how it compares to mobil 1.

[bennjamin]

Thanks for the response guys, Ben what oil are you currently using for the winter season? 10-30?

Try castrol edge 5/30
Most of the year I use calibre 5/30 full synthetic from supercheap auto - made by caltex and similar / same as honda feo fluids
But cheaper. Summer or track use i use castrol edge 5/40 (i think
It is! Alittle thicker for protection from excessive heat)

[c01567]

what do u guys mean when you're saying a tank
are you literally running your car till it has no more petrol in it? or are you just saying you usually get 400 before you fill up?
fyi my one's about 9L/100kms

[RPS.13]

46.6lt/526km when I filled up today... light came on when I started the car after work which was at 524km...

[PeppeX]

THATS BLOODY GOOD! But ur doing highway kms right?

When did ur light come up?

My light came on and i drove for another 10km until i filled up. I filled up 38.9L. Havent filled my tank to full for a long time but i added up all my km and got 9.55L/100km

So i am guessing light comes on with 12L left?

Yeah I do approx 70-80% highway driving. 100km zone on the highway... the light came on at 524km. Filled up at the closest BP, which was only 2km down the road.

I quickly calculated all the lt/km's that I have kept a record of:
44lt/495km
48.3/531km
44.4lt/500km
43.97lt/523km
39.2lt/457km
41.7lt/517km
46.6lt/526km (latest tank filled)

The average lt/100km for the above 7 tanks works out to be 8.67lt/100km.
If I calculate that into the latest tank filled, my light came on with approx 3.4 litres left, which is about 40km of travel on reserve... Which sounds about right?

Hi guys. Didn't notice this thread as I started up another one in regards to fuel consumption...

I'm currently on about 360km with petrol gauge just above empty. Petrol light isn't on yet. From what I've been reading here it seems I should be expecting better economy than what I'm on. Granted I have been engaging vtec a few times. A bit excited since I just got the car... And I do a lot of stop start driving.

Should I be concerned?

Its not how far u go. It depends on how much petrol u need to fill up the tank when u go to the petrol station. Because all our low fuel indicators seem to come on at different times.

For my honda jazz, the manual says the tank is 42L and fuel indicator should come on at around 7.9L which is 18% until the tank is totally empty.

So for our EP3 18% of 50L tank is 9L

RPS.13's fuel indicator comes on at with around 3.4L left which is very low..... my indicator comes on with around 12L left which is quite high.

Guess we all just got to learn when our low fuel indicator comes on.

I think everything should be fine unless ur getting worst consumption than 11L/100km when driving like a grandma.

Nah. I get about 400ish around town driving with NO vtec at all. You waste fuel idling at traffic lights in traffic jams and lugging about in 50 zones in too high a gear (2nd or 3rd)

[SDKBOI]

Thanks guys. Just filled up today and it looks like I've only used around 36 litres. 10L/100km I'm very happy with :)

[RPS.13]

Amazed with my fuel consumption/economy once again!!! Got to work this morning 602.9km!!! on the odometer and the fuel light only just came on when I parked the car on a slight angle. No difference in my driving style either. I did a spark plug, oil & oil filter change mid tank at approx 250km. I'm surprised that the new plugs have increased the economy by an extra 75km!

Which plugs are you using?

[RPS.13]

Which plugs are you using?

NGK iridiums: ZFR6FIX-11

[PeppeX]

NGK iridiums: ZFR6FIX-11

Are those the spark plugs we should use for EP3? Because this thread says DC5R uses NGK: IFR7G-11K http://www.ozhonda.com/forum/showthread.php?125834-DC5R-Major-service-question

[RPS.13]

you can use either...

the ones I pulled out, which came on the car from Japan were the NGK: IFR7G-11K

the one I purchased and put in were the NGK: ZFR6FIX-11

same thread size, same gapping of 1.1mm, both iridiums, only difference I can see is the heat range, with the 6 being the hotter and 7 the colder plug.
it's suggested that if you have a high performance engine to normally go a colder plug i.e. heat range 7.

the ZFR6FIX-11, was more commonly available and seems to be cheaper of the 2, the shop I get them from did not even stock the IFR7G-11K...

NGK have also updated their website as well since the last time I checked, which was before I bought the ep3, they only had the listing for the DC5. now they have a listing for the EP3 which is the ZFR6FIX-11 plug. they now have a drop down for honda import: HONDA IMPORT Model Civic EP3 K20A (http://ngk.com.au/sparkplug_cars.php?PageMode=Results&Make=HONDA+IMPORT&Model=Civic+EP3+VTEC+DOHC&Year=12%2F01+-+09%2F051.8LK20A)

not too sure why it is listed as a 1.8lt though...

[PeppeX]

Thanks for that cleared things up. So did u install them yourself? Seems like a pretty straight forward task http://type-r-owners.co.uk/articles.php?articleID=howto_changesparks_ep3_dc5

[RPS.13]

Yep fit them up myself... and read through the same DIY guide a while ago... before I purchased the ep3. Yeah its a pretty standard/straight forward plug change really.

Only thing to look out for would be the nut/bolt connecting coil pack ignitors 2 & 4, you'll need a 10mm deep socket to get them off or a ring spanner should work too.

I use permatex anti-seize lubricant on my plugs as well, not really required but it makes it easier to get in and out when changing the plugs... I use it on pretty much all my bolts (anything that I undo on a regular basis).

[muzukashi]

I'm getting a lousy 300~320kms a tank and driving like a oldman :(

Only running GruppeM and Buddyclub headers aswell! looks like spark plug change on the way?

That's not much at all!

I did 385kms and filled to the top today with only 36 litres so still had about 20 odd in the tank at time of fill up.

[quangsuke]

is that normal for a ep3 to be getting such low kms on a tank?
would of figured it atleast hitting the 450-500 mark.

[muzukashi]

Nah i don't think its normal gona give it a service this weekend when the rain isn't being a bitch,

Will be happy with anything pushing around the 400 mark :(

[JohnO]

well my guage is pretty much off, it was red at 335km and i refilled 34litres and its a 50l tank

[PeppeX]

Well it really does not matter what km u hit. Its about how much petrol u need to put in to make the tank full again. Our low fuel light seem to come on at different times. My car comes on with around 12L left, RPS.13 ep3 comes on with 4L left.

As long as your car is doing 10L/100km its fine.

Symphorced got 385km out of 36L which makes its 9.35L/100km

muzukashi how many litres do u usually fill up with 300-320km?

[muzukashi]

Yeah gonna have to start observing this properly now haha

Roughly about 30~32

[PeppeX]

Then u got nothing to worry about :). I dont know why our fuel indicator vary so much....

[muzukashi]

Yeah its kinda odd how identical the car is but yet fuel consumption is so different

A mate of mine is pulling atleast 450kms and still has like a few notches to go and his got similar mods as me, odd but oh well as long as i don't have to pump $70 to fill this up then i'm ok with it hahaha

[PeppeX]

Ask how much fuel ur mate puts in and report back to us :)

[muzukashi]

I think his been pumping around about 34ish which is only a few liters more then me yet gets 120~130kms more which is quite weird lol

Going to probably change sparkies and oil & filter on my baby tomorrow and hoping to see at least a slight increase then i'll be happy :)

ooo... does he drive hwy alot more than u? Are u changing spark plugs urself? I am thinking of changing too, but was hoping to get someone who has done it before to guide me through. What spark plugs u using? Where u get them?

[bennjamin]

just to mix it up - took the EP3 to wakefield - filled up just for before about 43l or so. Did about 60-70kms around wakefield full throttle all over the place - left the place with 3/4 of a tank. Drove home to Sydney - about 180kms. Had abit over half a tank left - then I proceeded to drive to work for the next few days and the tank was empty in another 150kms lol.
Point is our EP3 is great on the track and open road , but runs rich around town.

[stienerv2]

My last tank lasted 510kms and i filled up 43ls. This includes a cruise to singleton. However in normal city traffic my tank will only last me around 440km so roughly 10kms per litre and also my fuel light will come on around 8 litres left. For spark plugs i've changed it as soon as on got the car and they are bkr7iex-11 by NGK from jdmyard. If you want to change plugs, make sure you have a spark plugs remover tool cos cause this will make it a lot easier. Or even a spark plug deep socket cos these have a rubber washer in them to help pick up the plug inside the hole.

[spookz]

Yeah, the EP3 is great on fuel even when enjoying some spirited driving on open roads. It's all the stop-start traffic around town that kills the fuel economy.

I've picked up some spark plugs (NGK IFR7G-11KS) for my service next Saturday. I'm interested to see if there'll be any sort of difference after my full service.

[PeppeX]

Just filled up did 8.4L/100km with vtecing and heel toe! So good fuel eco, must be because of my new CAI and cold winter weather :)
