Fuel Consumption DC5, DC5R, DC5S

[WATAJK]

Wondering what all you guys get out of a tank roughly?
I generally always use BP Ultimate, before was using V-Power, im getting roughly sometimes 400km outta a tank pushing hard, mainly city sorta driving..

Best ive had was 500km with basically almost all highway driving

BTW i search'd for a similar thread n found nuffink lol

[DoAvl]

sounds like something i would like to know as well!

car: DC5R
avg: at least 500km
driving: daily commute to and from work, vtec here and there.
Fuel: BP Ultimate

[r3ckless]

is ur car stock... best i had was 9.2l/100km, but i avg 10-11.2l/100km... i camnnot drive it soft so yeah lol.. mines stock btw.. also, i use bp ultimate only

[WATAJK]

Well once i did 150km on half tank?
I fink i ****ing kill'd it left right..
My car is stock apart from 2'5 Catbak...
Idk, sometimes my economy is good but most times its shit

Any recommendations?

[r3ckless]

i am nto really happy with my fuel cosumption, if i can get into the 9's ,i'd be cherring, i think i can.. but basically 2-3 days, i can drive it soft, and then i just gotta hit the redline lol, and ater that, tis all over, i keep driving like that. but what rev's do u guys usualyl shift at?

400km and 500km are useless figures. You need to report as litres per 100km, so you get proper fuel consumption numbers.

BTW, what is "nuffink"?

[endymiony2k]

I had the same problem too, my dc5r can do about 400km for full tank, mainly city driving

[WATAJK]

Well im hitting 11-12L/100km AT LEAST sumfin like that.
From what ive been told you need give it a thrash everynow and again or else the ECU plays up, VTEC engages later so it needs a push but come on
I dont get how my ****ing economy is that bad

Sorry aaron mate but how i spell nothing is nuffink.. Got into the habit like 3 years ago mate.. Its italian thing lol
All my mates do it 2 lol

[TypeS]

Average with stop go traffic; 480km using Mobil 8000.

Highest ever 770km on GOR!

i'm assuming all models have a 50L tank? i'm probably wrong.

assuming mine is a 50L tank (02 dc5r), then it's about 10-10.3/100km.

Mines 50L, aswell, pretty sure ur right with that 1 mate

But you can't run all 50L in the tank because you end up stranded by the side of the road.

I fill up to full tank, drive maybe 200km and then fill it back up to full tank at the same petrol station. Takes the number of litres and divide by kms and multiply by 100 to give L/100km.

[r3ckless]

wat rpm, dooes everyone shift at, when saving fuel?

[cupnoodle]

My stock DC5R is getting ~330km from ~25L

So that's roughly 7.5L/100KM (shifting at 3k with lightish throttle, redlining about twice a week)

hahaha. that's true. hence i said at least 500km per tank on average. i hardly ever hit the fuel empty light, it usually hits 500km's first. and 50L might be +/- a couple of litres.

wow, gotta give it a try for a week llol.... is that 3K on every gear?

might try that LOL

[cupnoodle]

you guys must drive it pretty hard LOL

[cupnoodle]

wow, gotta give it a try for a week llol.... is that 3K on every gear?

Yeah every gear. However, WOTing it to 3k wont do much either

[r3ckless]

also, I noticed, when I take off... first gear to second.... if I shift at 3k... I feel im goiing to slow, as traffic is on my booty

[Zinyo]

im getting roughly 500kms on a full tank...i only shift at 2.5k and have the occassional vtecccc probly twice a week or so...i noticed after installing my intake, fuel economy is better.

[WATAJK]

IDK i vtec at least 5-6 everytime i drive lol which is maybe 4 days a week...
Mayb thats what is ****ing me up?

[cupnoodle]

Definitely Yes!

[smomo]

I get 8-10L/100km in my DC5R, usually around 9L/100km, this is all city driving.

About 6.5-7L/100km country driving.

figures taken from various sources

i made a spreadsheet one day when i was bored comparing all the cars on my wish list (long list lol) and some others just to see what the fuel consumption and stock out-put, weight etc was

if you want more of other cars let me know lol

[WATAJK]

Wow very handy list mate
Cheers
Well my dc5r is no where near that haha

[aidannn]

i get about 10L/100km city

[Hullabaloo]

depends on what type of driving/trip i'm doing. if it's 60% highway, 40% city then i average about 7.5-9L/100km.

if it's purely city type driving then i average about 10-12L/100km.

pure highway can be as low as 7L/100km

I've recorded and graphed my fuel weekly fuel consumption figures over since march 2007.

from the beginning to "2" was my 60/40 highway/city in adelaide so pretty stable.

"1" was when i put in gruppeM and reset ECU so had a higher fuel spike for a little while.

"2" was when i first arrived in melbourne and the stop/start traffic driving started.

The "3" massive spike was from a very short 50km drive/fill on a cold cold morning. followed by "4" a drive back to adelaide.

These days i do a lot less km per week, mostly driving in traffic with the occasional spurt so fuel consumption is considerably worse than the majority highway back driving back in Adelaide.

[DC5-S]

Hmm, seems u guys have high figures.

I usually fill up BP Ultimate, price 145.5, $40 gets me 250KM.
But its funny, if i fill up a full tank for around $55, i only get 430K........

Maybe its the way i drive.....lol

[TYP32]

Similar figures to u 2 DC5-S, im using BP Ultimate and around town im gettin 430kms/50L tank or 11.63L/100kms. Can pull upwards of 600kms+/50L tank or less then 8.3L/100kms highway driving.

Thing is tho, it all depends on your mods, tune and the way u drive your car, we all dont have carbon copies of a singular DC5 so we will generally have different levels of fuel consumption.

[akina]

yea a tank takes me 450+kms... calculated once and that ended to be around 11.6L/100Kms. About 15% highway 85% city haha
I put in Mobil 8000. Only petrol station that ain't PACKED on a Tuesday...

[Zinyo]

Random questions guys;
1.)Is there any difference Vpower and MOBIL??
2.)What rev range would be the best to change gears so as to increase fuel efficiency?
3.)Totally unrelated...but what tyre pressure combination is best for FRONT/REAR to increase fuel efficiency for us DC5/DC5R/DC5S owners...i know underflated tyres have a massive impact on fuel...

[WATAJK]

1. V-Power is more recommeded as Shell have a larger majority of the market.
2. If u want great fuel economy shifting at 3000-3500rpm is an idea.
3. Yes you correct, underflated tyres kill ur economy but also overinflated isn't that great either, i have a set PSI on mine 36PSI which is generally the best for driving on but your car manufactor generally recommends another PSI as it increases the comfort for your drive.

Hope this helps

4 psi higher then the tyre recommendation/manufactures specs will give you better econermy and a slightly stiffer ride.
manufactures prefer a slightly lower pressure as it adds for a smoother ride.

you will notice the difference in stiffness with 4-5psi more and you will get better economey and will perform better,
but if you put to much in 6psi+ you will damage your tyres and there is no point to do them that hard.

[its_ish]

I guess there are a lot of factors to consider that can affect fuel economy.
From tyre pressure, driving behaviour, drag coefficient to mechanical condition...
I used to get 450K's on a full tank on mine when I had a K20a3 engine in my luxury...im sure im gonna get less now with a K24...but hey, more fun!

[r3ckless]

hey guys, i only done 50 km so far... jsut went n filled u p30 odd litres bp ultimate again.... i did 236 km all up including the 50 earleir 2day.. aso the extra roughly 200km was all from the national park(twisties)... and jsut filled up full tank, and did my fuel consumption.. WTF 9.8 litres, and i was giving it.... that osunds off .....

[DC5-S]

I put in Mobil 8000. Only petrol station that ain't PACKED on a Tuesday...

Mobil 8000 is the purple one right? That fuel is awesome, can feel ur car a bit faster.... haha, but mobil is so rare, CBB driving so far to one to fill up.:thumbsup:

[pinoy-boi]

i agree. im lucky, theres quote a few mobil fuel stations around my area, car feels moer responsive running mobil 8000. bt i get more fuel economy out of v-power

wow...bumpy ride??

[air23box]

wow? 200km difference ? why? stock ecu?

yeah.....street is mugen twinloop and stock ecu...
track is Mugen N1 exhaust which have no cat no hotdog but only a little muffler at the back....70mm all they way.....with Mugen N1 Ecu which idle at 1000rpm and fuel pump on at all times....thats why...but you feel like driving a different car tho......when I put the street parts back on I will feel so slow....lol

[typeS__]

I use vortex 98 for dc5S and i get about 450km from a full tank no mods

Mobil Synergy is great!

Power is more responsive whilst you save on fuel consumption

BP Ultimate only gets better if you use for the long run, but when you ONLY start using it, it wastes fuel faster

Also, guys how do you fill up? Do you clunge it all in, or do you do it slowly? Because putting petrol slower is a benefit right?

[Nepolian]

Off track, but anyone in Sydney with a stock b-pipe they wanna sell?....pm me :)

BP Ultimate or Synergy I get 530-550km

Shell I get 480-500ish........big difference, but you can get the V-power anywhere between 4-8 cents cheaper, so its all relative I suppose!

All just regular driving with a little vtec here and there!

[bboyzell]

i belive that is a myth

[45SET]

I haven't put a full tank of petrol in my car since I put the K-pro in, but with 50/50 urban/highway driving I was getting about 250km from half a tank... I honestly don't even look.

[Hullabaloo]

2nd half of the fuel gauge always seems to go faster than the first half. i've gotten 350km to the half way mark thinking i'd get 700km from the tank before but ended up with only 550 before fuel light.

[Nepolian]

Not where i am! Usually 1-2 cents cheaper and then if you have a discount docket another 4 cents :)

[akina]

Nah, Shell is normally cheaper than Mobil by 1-2 cents + docket. Thats why they are always PACKED! Same goes with Caltex.

Mobil ftw. Zero waiting time :eek:

[MrCEO]

Driving DC5S stock. Tried all the major brands of fuel, Caltex (Vortex 98), Shell (V-power), BP (Ultimate) and Mobil (Synergy 8000).

First off, I prefer Mobil Synergy 8000, the car just feels a lot smoother while changing gears and reving all the way to redline. Comparing shell, BP and caltex, u get a stutter then comes the power, not a lag per se but u could feel the engine vibrate a little during the initial rev to redline. Consumption wise, insignificant differences between the brands. I vtec like once a week or so.

Regardless, i think its up to the individual car that determine the outcome of fuel consumption assuming stock standard and normal driving conditions. Older cars inevitably spend more fuel just like the fact that it will never reach its advertised power in stock standard conditions.

[r3ckless]

im getting rpety good fuel consomptuiopn.... havnt redlined it all week, jsut hit 6-7K a fair few times each day.. ehres a pic LOL..usually by half way, im at 250km! so im rpetty pleased.

[air23box]

sorry to hijack....but just wanna to ask.....you just can't type or can't spell....:p
U make it very hard to read what you type.....lol

[r3ckless]

haha sorry man, im taking english lessons and slowly getting there. english is my second langidge

[air23box]

haha sorry man, im taking english lessons and slowly getting there. english is my second langidge

Nah...its all good bro.....just do a spell check b4 you send it out next time.....;)

[WATAJK]

haha sorry man, im taking english lessons and slowly getting there. english is my second langidge

dw man, i was doing italian for 18 years of my life lol
I know what its all about :P

[markis]

anyway back on topic. My mate went fr0m sydney to brisbane and i think he said he got 800kms out of the tank

[R123]

800... thats certainly a record to beat

[WATAJK]

anyway back on topic. My mate went fr0m sydney to brisbane and i think he said he got 800kms out of the tank

i'll believe that anyday.
Im going sydney early nxt year with my dc5r (will try not VTEC it) hopefully will get some fantastic results :)

[Zinyo]

i'll believe that anyday.
Im going sydney early nxt year with my dc5r (will try not VTEC it) hopefully will get some fantastic results :)

i think in his case, he was at constant speed while being very careful, no A/C, windows up, not taking toilet breaks, limited audio...mite ruin the drive...800kms...

[markis]

now apparently its 600kms per tank. :D.... sydney to brisbane. someone told porkies or i missheard

[onesweetb0i]

What should i do if i only get 380km's out of my tank? Is this unusual?

[WATAJK]

What should i do if i only get 380km's out of my tank? Is this unusual?

Have u been VTEC it hard like everywhere? That would explain alot lol..
Worse result i ever got i think was 350 but i basically redlined everytime i was driving in the lower gears... Bad week of fuel >.>

[gilby126]

What should i do if i only get 380km's out of my tank? Is this unusual?

lol dw last 2 tanks ive been in the vtec-ing mood...been getting around 350-400 ha...

[r3ckless]

dont buy an injen cai.. i have, and my mileage is soo poor!

vtak too much

[onesweetb0i]

no no, no vtecing. i thought this was the issue, but i recently filled up and drove extra slow just to see how much i could get out of it. I probably change every 2.5-3,000 revs..

[WATAJK]

no no, no vtecing. i thought this was the issue, but i recently filled up and drove extra slow just to see how much i could get out of it. I probably change every 2.5-3,000 revs..

thats very odd...

[onesweetb0i]

think i need someone to take a look at it??

[kctt]

I used to own a DC5R and the best I ever got was 680++

[onesweetb0i]

omg.. i wished i could get 400!!!! let alone 680 ..
so how do i fix this problem??

[DC5.Raven]

What should i do if i only get 380km's out of my tank? Is this unusual?

That is weird. I still get at least 450kms when shifting at 4-4.5k.

[markis]

ok ive only done 265kms in the integra since owning it. cause of my work car. but ive managed that with around 1/3rd of the gauge. so should be interesting what it gets. :)

[markis]

ok guys i ended up getting 540kms and thats very mixed. 2 mountain trips aswell :)

alot better on fuel than the evo

[[Type_R]]

Im getting about 400-450ks to a tank with injen cai and vtecing atleast once a day hahah! 50 city/50 highway

Used to get 500 standard.

Btw, i always use Shell Vpower..

[burak213]

boys, it depends on highway drives and cold starts with 5 min drives

[r3ckless]

ever since my cai.. my mileage has gone up the rooof! bloody VTAK

[markis]

wouldnt denser colder air make more power and burn leaner as its denser so it should be more economical?

[onesweetb0i]

so how do i fix the problem??

[DC5.Raven]

wouldnt denser colder air make more power and burn leaner as its denser so it should be more economical?

Thats not necessarily true.
Cold Air = Denser & More Volume (e.g. Oxygen).
Hot/Normal Air = Thinner & Less Volume.
The engine management system in your car will take into account the density of the air thats coming into the engine. It usually wants to keep the mixture of air and fuel at a ratio that creates complete combustion (thus more efficient, more power and also cleaner emissions).

Thus when you have a CAI, the engine management system will inject more fuel to keep this ratio and account for more oxygen coming in, giving you more power (but using more fuel).

Without a CAI, there will simply be less fuel injected to keep that same ratio.

Makes sense.

[markis]

;2614645']Makes sense.

it does if you think of it that way. but most of the time its more efficient to have cooler air channeling into the engine. less strain on engine and more flow equals less resistance which would be power lost and energy lost which would be more efficient if put to use driving the wheels.

[onesweetb0i]

450 last tank, finally woo

[xhilr8]

Stating how mank kms you're getting on a full tank isn't really accurate..what exactly do you mean "a full tank"? Until the light comes on or are you guys driving till the engine dies : P
I'm getting 8.43 litres per 100kms for those interested..so on a 50litre tank that's 593kms.
