Fuel Economy of your DC5 Type S

[alexai.dc5-s]

Hello Guys,

Just wondering how many k's you get on a full tank of 98 octane premium unleaded fuel on your type s. My average is around 400k's (stock motor) and I have a mate who gets 500-600ks (full catback exhaust and headers) how does that work?


Can someone please help??


thanks.

[obsessionz]

Maybe he drives like a grandma? i've owned DC5S also in the past and DC5R i could only get an average of between 400 - 430 kms


Your friend could be driving with the petrol light on for 80kms on empty?

[alexai.dc5-s]

yeah its odd because i can easily get 280-300ks on the first half but the whole tank is around 400??

[r3ckless]

I have to completely disagree. I have an 05 type s. I get 500-500km and the petty light has just turned on.

I basically drive cruisey and shift at 3k rpm .. hit high revs maybe once a day if that, and on weekends, i drive it harder and hit up RNP weekly. consistently 500-550klm a week. I run 98 bp ultiamte only. This was the case on stock motor / injencai+todaheader+spoon n1. its funny, cos my gf's dc5 luxury can get 500k klm on petty light turning on - she doenst thrash it at all, but it is an auto.

[obsessionz]

hmm weird hey ive never got 500kms on any of my cars, DC2R, DC5R, EP3, DC5S lol maybe i just drive it real hard? only unless i do lots of freeway driving then Ill get 500kms

I run 98oct on all my cars owned and service car every 5000kms

[r3ckless]

How is your drving habit? what about your left foot? Sometimes when i give it a heavy foot to like 6 or 7k (this is in 2nd to 3rd) and when i go from 3rd-4th-5th-6th; i dont even accelerate... I just cluytch in and out until I hit 6th gear. Just have a quick method of releasing the clutch and grabbing it also so revs dont drop at all.

[JDM-EGG]

my gf's usually get 400-450 on bp ultimate on a fully bone stock type s, dont use other fuel cause its even worse ! LOL

[mrntegra]

i get around 500km's to a tank of city driving/little hiway using shell V-Power.. about 10km per litre but if all hiway driving 600+km's isnt out of the question..

[r3ckless]

Thats pretty good matt! I noticed on other cars vpower burns quick!

[WATAJK]

BP Ultimate FTW!...
I get between 400-480 on daily driving...
FWY driving i can get 550-600+ Done this before when i drove up to Bright (Wangaratta)

[.k.]

i beat you all! 650km to a full tank in my dc5r with intake header and exhaust. but i baby my car <3 shift under 3k ftwwwww. this is all city driving too :wave: woo

[r3ckless]

Isnr casino like a more spreadout city than sydney?

I have tried many times drivng an entire week and shifting under 3k... Cant resist temptation when you have A hot exhaust note lol. Im sure if mune was a stock setup i wouldnt rev it lol..

How come this thread hasn't been closed yet? I mean, some mod saw fit to lock my thread asking the same question about DC2/DC4/DC2R fuel consumption, and it was closed.

I don't see why this thread should be closed, and of course I don't actually believe that it should be, but it just seems like entirely stupid double-standards.

Maybe I'll just PM my question to every member of the forum, as posting threads seems to be against the rules.

thanks.

Your fuel economy is normal, 10-12L/100Km is the norm for a stock type s.
The general consensus with adding an aftermarket header on the stock map is, it increases your air-flow, thus leaning you out a bit, resulting in an increase in fuel economy.

You can get some sort of ECU management to tune it back, which can only be healthy for your motor in the long run. Or you can brag about it like this bloke;

Welcome to Ozhonda

[Rubes]

I get about 430Km's (400km if I'm feeling angry for the week lol) and when I fill up it only takes about 40 litres. So 10 litres left. Never seen the light come on yet since i've bought it.

[18dim]

400km was the norm with my type s aswell.
Even my s2000 is about the same.

dont know how these ppl manage over 5-600km..
lol

[r3ckless]

I havnt filled a tank i my car for 6 months.. How big is our tank? 50L yeh?

My car is serviced very regularly! Im even consideringchanging
Fuel
Filter when i get my
Licence back

[dlai5552]

Hey man,
I drive a dc5, have Intake, headers + cat, catback and a KPRO tuned...
still get 550km on average.
However it is a Type R, not too sure if there is a difference. And my car is tuned, hence I dont drive like a grandma too much. a like to hear vtec at 5000rpm :D

[EVLGTR]

A friend claims he can get 717km using bp ultimate out of near-stock DC5S (pod filter mod only), with hard compound tyre pressure weekly monitored at 38-40psi, urban daily driving shifting at +/- 3000rpm. It sounds unbelievable but might be plausible since riding with him 5 days straight to and from work with reading of 668km (on his "trip A" odometer) and still had around 1/8th left on the fuel gauge

***EDIT**** may i add, he also puts his gear to neutral to let it roll most times approaching within 50m of traffic/traffic lights and in some occasion jumps gear from 1 to 3 to 5 & 6

[obsessionz]

EVLGTR your friend sounds like a tight ass making such effort to save petrol lol

[r3ckless]

True that, i've also heard that you hsouldnt skip gears etc, even if you blip it. you should always cycle through all the gears. So in the shrot run he may be saving money in petty, but a rebuild of a gearbox will be costly

He probably uses the whole tank of fuel whereas most people here only use down to the light, which differs between cars/models.
Also, he is not saving petrol by putting in neutral. If you stay in gear with your foot off the throttle you use zero petrol. I will be in 5th, blip to 4th, blip to 3rd, blip to 2nd before coming to a stop. The whole time im in gear im using zero fuel. I use a bit by blipping but probably less than idleing would as he slows down.

I get 8.5L/100kms on average (some above, some below) all in the city.

95% of people in this thread need to get with the times. If you want to know your economy then do it properly. None of this XXXkms per tank rubbish. How much you filled up at the tank in Litres divided by how many hundred k's you travelled on it.

55L for 550kms is 55L/5.5 hundred kms = 10 L/100kms

I don't even go down to the light? lol...
I hit 1/4 of tank left and i re-fill...
^^ Now thats cheap, btw thats with 450km and 1/4 left, with exhaust and INJEN Cai and thats with regular VTEC, no tight ass here lol.

[munkaii]

Wow you guys are crazy...

I'm lucky to reach 400kms from around 40L!

[v-tec bro]

450 before the light turns on. i shift at 2.5k most of the time with the occasional reving

This was done out of curiousity to see his maximum fuel save out of a DC5S. Why shouldnt you skip gears?, he does it so smoothly without even noticing he ever changed into gears. He skips it by going up, not down shift so he doesnt blip it at all

Causes uneven wear over the synchro's and your putting more stress on the motor plus gearbox.
Common skipping of gears would be people going from 1 - 4, 2 - 4, or even 2-6.

Regardless if you double clutch or not, you will create uneven wear across the synchro's.
Slowly, slowly you will also be eating away at your clutch and flywheel too.

Sure you can double clutch, rev match it perfect and the car might not "choke" back at you but it will stay create uneven wear as your skipping one entire gear to jump up possibly 2 or even 4!
This is why we have sequential gearbox's! =)

BTW, this is a great topic, very good one to discuss! :wave:

Yup, I even rev match to go down gears, everytime. Only time i dont is if im going real slow eg in traffic, and it goes striaght into neautral for a complete stop.

We all know that it does cause some slow wear on the synchros if you put some stress on the gearbox. He doesnt even double-clutch or rev-match. All i know is that he gets in 1st gear > 3rd > 4 > 5 and 6, so he's only jumping a gear, in a very seamless motion while the ride feels as light as a feather.

I think what he was trying to show me is that you can do it, instead of following the conventional driving style of doing it in a sequence. Not only 1-3-5-6, he uses 2-4-5-6 gears as well, wheres the uneven wear on that?

[staryknight]

My fuel light comes on about 430-450kms, ive pushed it past 500 on a single tank before with city driving. Of course this is driving mood dependent. If I boost and vtec everywhere it can easily drop to under 400.
Highway driving i get 550-600+.

Recently I had a wire powering my coil packs broken by a body shop and was running on 2 cylinders for about a month, and was barely making 200kms on a tank, fixed it up myself and back to all 4 cylinders and sweet as again. :D

If you read my last post correctly, you'll understand what i mean't by uneven wear.
Regardless that he may take off in first then jump to third on one occasion, there are plenty of other occasions where ALOT of DC5 owners decide to take off in second... I don't see why they do... Very silly as we have a sequential gearbox thats there to be used...
It depends how often he skips first, second etc etc...
Uneven wear occurs, how badly it occurs... well depends on the condition of your gearbox..

BTW, currently at 402km on this tank, just above 1/4 left

LOL, no offence, you are on my good side atm but I have no idea what you're babbling about mate....i dont know any drivers in general that would take off in 2nd gear. You better ask lots of these DC5 owners here if they take off in 2nd gear coz if they do then they are a bit silly, if they dont, it makes you sound silly.
When i mentioned "he uses 2-4-5-6 gears " its not what i meant he takes off in 2nd gear. The scenario is that he slows down approaches a corner puts it into 2nd gear then jumps to 4 then 5 then 6 gears.
He still uses all gears 1-2-3-4-5-6 but in an unthorthodox sequence but does it with such smoothness. You're doing alright but please explain in detail how an "uneven" wear on synchros occurs coz im still baffled and he (friend) was a bit baffled as well. (im not here to make fun of you though)

Wasn't all in reference towards you though? (What i said that is? It was a general comment? lol...)
Marked something in bold that you said, when i shift down, i gear down, gear by gear (rev-matching) when i know there's a turn coming up, this isn't necessary (i don't think but reduces uneven wear if done correctly) but this is how i choose to drive.
There's nothing wrong going from sixth to second when your about to make a turn or fourth to second, well i wouldn't think so? BUT, i dont believe in once you start going down the street that going from second to fourth would be a good idea. Once again your skipping third. Sequential gearbox is there for a reason :)

He is using 3rd gear when he starts off from 1st > 3rd...so on therefore he's activating the sychros on 3rd. I dont know what you meant by "uneven" wear though coz eventually he uses all triple/double cone synchros in his DC5S.
Ok lets lets simplify it to middle school level for the sake of our conclusion, he says he doesnt change gears in a sequence 1-2-3-4-5-6 then 6-5-4-3-2-1....on a long stretch of road he does 1-3-5-6 then slows down to 6-4-2 and this is what he meant by saving fuel PLUS dont forget i mentioned he shifts at 3000rpm so there is very little load on all synchros.

Anyway, he says it can be done coz otherwise you might as well drive a car like probably yours with those semi-automatic +/- sequential gearbox or a paddle shifter or something similar, lol, he appreciates the beauty of a manual car such as his Type-S with an awesome multi cone gearbox and how it can be variably driven and gear changed to run the max economical distance (he claims). Cheers !!

I give up, theres always an excuse or an explanation.
Your causing uneven wear between synchro's because regardless that your going 1-3-5-6 then 6-5-4-2, your rev's will not be the same as when you shift up or down... Your rev's and how you shift is how the difference between how much damage is caused to each synchro as there individual parts.

of course there will be wear and tear occuring on all synchros over time, i just dont understand how "uneven" it would be if you're using all synchros. my friends definition of UNEVEN is using only gears 1-2-3 and completely shutting out gears 4-5-6 etc for the rest of he's cars life....that sounds more obvious.
Its not even a big deal to him skipping gears at a very smooth and light load, he's been doing it in his previous old car that had over 450,000kms on the gear box and still shifts normal.
im sure honda gearbox quality is one of the best in the world, its not as if it will come to a sooner point where you have to overhaul the whole gear box coz its been driven in an unorthodox way like my friend does. hahaha. its unorthodox just to save fuel but he aint thrashin it.

***edit*** if you're rating the so called "uneven" wear on synchros in a microscopic level then hands down i agree with you, LOL

Well i suggest you go do some research and go research uneven wear on synchro's then.
You dont even own a Type R/S yet you post in every thread like you know everything just cause your mate apparently owns a Type S

[munkaii]

I believe that yes, when you hop gears say between 1 and 3, as opposed to going from 1-2, the revolution difference between the synchros for Gear 1-3 as opposed to Gear 1-2 means that when you shift from 1-3 and 3rd Gear synchro meshes, it needs to do more work due to the larger difference in rotational speeds, thus wearing out 3rd gear more than shifting from 1st to 2nd, and then to third where the synchros don't do as much work.

Yes you may be shifting smoothly and letting the clutch out smoothly, but as soon as you put a car into gears, the synchros are doing work before you even start clutching out so it doesn't matter how smooth the shift.

[EVLGTR]

I couldnt find any, care to search for "damaged gearbox due to skipping gear at a light load". So what if i dont own a DC5? a gearbox is a gearbox.
My mate doesnt hv an account so on behalf wants me to do the posting.

@munkaii: Ideally, yes

We did, generally everyone says theres no major damages. No one has to agree to anything. Its the way people drive and the general population says its ok to skip gears, like i said, ideally you dont have to but you can but we just dont get why we all SHOULD follow your conventional sequence change of 1-2-3-4-5-6 and 6-5-4-3-2-1. It is a waste of time, when you can just slow down from 6th then drop down to 4th or 3rd or 2nd depending on the speed of a corner.

the gearbox is designed for it?
You really think Honda would waste all that money in the design of a gearbox if it wasn't there to be used? Just saying.
Btw, if you ever do track and if you've ever watched someone's video, no-one jumps down 2 gears... they go down gear by gear to help them slow down but also so they can be in the right gear for the corner.

Oh really??????? what does going to the tracks have to do anything with fuel saving?. He doesnt track the car, its a daily driven car. A sequential gear box with +/- like your novice gearbox is designed to do it in sequence perhaps but ours is a manual therefore it can be done in sequence ideally OR you dont have to. lol

***edit*** On the contrary I really think Honda wouldnt waste all that money in designing one of the best gearbox with multi cones only to be rebuilt after a short period of use due to your theory of uneven synch wear :)
For the record of Honda quality, my friend here added, the DC5S is only equipped with synchronisers triple cones on 1-2, double cones on 3 to 6 (with 5 & 6 using Carbon synchros), so i dont about your DC5 sequential gearbox quality.

[l__i__l]

LOL i skip gears all the time! and ive done nearly 185K with the original gearbox! DC5s have close gear ratios so theres no harm

and I reckon u prolly wear out ur clutch and synchros more from needless shifting if anything

lets say i drive daily averaging 30 "proper" shifts a day, and if i skip gears its only 20 shifts a day

so in a week thats 210 proper shifts and 140 after skipping gears

in a year that makes it 10,920 "proper" shifts and only 7,280 after skipping

i think the 3,640 extra shifts will wear out ur gearbox more!

None of this I reckon junk lol.

To the average joe, they won't have any idea how the synchros are going on their car unless you are starting to crunch gears. In theory, skipping shifts will force the synchros to do more work due to the revolution difference between different gears. The rev difference is smallest for the next corresponding gear. So technically, yes more synchro wear. Shifting gear by gear will reduce synchro wear.

Just because your mate drives and skips gears during his shifts to his fuel economy and does so smoothly does not mean his gearbox synchros are not wearing more. So unless you've cracked open a gearbox to have a look at what the synchros are like, and then compared it to a box of the same condition driven without skip shifting, then you can't make any judgement. You may not see any effects of synchro wearing until the later half of their life (I doubt any DC5 has gone through enough shifts to warrant synchro wearing unless you drive one as a taxi) so you can't say it doesn't wear.

Just because your mates gearbox runs well doesn't mean it is wearing unevenly. The effects of synchro wear take a lot longer to appear, however it does happen.

Trolling r we EVLGTR?

these reckons are all opinions mate incl urs!!

noone has done any testing its a controversial subject which has been done to death

you say uneven wear will occur after years yet there is no evidence it back this up

theories are very different to real world implications!

and you dont need to open up the gearbox to find the answer just analyse the gearbox oil for metal conetent!

Skip gears for 10K-----> analyse the oil for metal content
shift conventionally 10K---------> analyse the oil for metal content

higher metal content= more wear

Will post up my fuel economy tomorrow... you will be amazed...
Full tank i had before i left.
Re-filled on way home... was surprised how early the light went on >.>
Realised how much more i could of got out of the car!

Results tomorrow, mix of FWY, Low speed corners (Great Ocean Road)
