dc5r eating petrol

[jon22]

hey guys i just recently purchased a dc5r.

On a full tank im roughly getting 350kms. Im not driving it hard at all, yet my petrol is dying really quick. The engine looks stock as a rock, havent really looked at it in too much detail but does anyone have any ideas?

[Webby_roller]

how many km's.... depending how high it is, it could be time to replace your O2 sensor(s)...

Age deteriorates the sensors ability to read accurately and can cause the ecu increasing fuel usage and therefore your bad fuel economy...

[tmy]

What kind of fuel are you putting in it?

[jon22]

just the average unleaded petrol, and 72 000kms on the clock

[imratedpg]

you shud be using premium fuel only 98ron maybe thats why ur not getting much k's

[jon22]

even so, my mate is gettin like 550kms out of his fuel tank, wouldnt make that much of a difference would it?

[DC2-PWR]

just the average unleaded petrol, and 72 000kms on the clock

Yes but which petrol station and what fuel, BP Ultimate? Freedom e10??

On my vtir integra, i did a test on shell vortex 98 petrol. It gave me 300km on a 40ltr tank.

The week after I tried, BP Ultimate with abit of milage booster liqued, it gave me 485km on a 40ltr tank.

So from my understanding, choosing a quality fuel counts every km.

[Zinyo]

just the average unleaded petrol, and 72 000kms on the clock

u need 98RON petrol, not unleaded. give it a go and see what happen. I did a check on mine this time n its at 580 ish at close to empty today!! gave me a shock as well!..:wave: first time for me =] but then again mostly freeway driving.

[imratedpg]

hrm not sure but for me when i first used unleaded i onli got like 370kms since using premium i get about 470km's full tank, maybe change fuel filter i dunno

[burak213]

OP


you need premium

dont out that shit unleaded in there

[Zinyo]

even so, my mate is gettin like 550kms out of his fuel tank, wouldnt make that much of a difference would it?

yes it would. just go to coles for shopping and collect the 4c off dockets n buy it on wednesday nite n it should be very cheap to buy. u have a dc5r...dont cheap out...

[jon22]

noidea what 98ron is, but my mate uses v power? ill give it a run and ill get back to you guys

[Chriskoss]

noidea what 98ron is, but my mate uses v power? ill give it a run and ill get back to you guys

thats 98 ron.. 98 ron is high octane fuel like v power for shell and bp ultimate for bp..

[WATAJK]

Do keep in mind mate, 98 RON won't give you those figures always... If you just shifting at 3000-4000 RPM you should be getting figures towards 400-500+ Easily...

In my case im lucky to get 460km with no freeway driving as i love to push my ITR but then again thats the price you pay aswell when you've modified it to lol

As others have said "don't cheap out on these cars"

[r3ckless]

i have only ever used bp ultimate i my car....

first and foremost... for me, i believe out of all the 98RON fules, v power burns way too fast.. bp ultimate is the best imo.

But i get around 500km to my tank, but my reading is average of 9.0litres / 100km

i drive basically 250km cruising, and 250 spirited.

The other weekend, i went RNP and went up and down about 6/7 times... Gave it a good squirt! and i still got 500 km afterwards.

Also when you shift, the best time for shifting for power/fuel economy, i shift @ 3K

so shift anywhere from 2500-3000rpm. shifting around 2Krpm- dc5's struggle.

I also use a website called fuelly that tracks my fuel consumption; www.fuelly.com

I jsut punch in the price i paid for my fuel, the km i done, and the amount of litres i filled up. Tells me all this info and average consumption etc!

[seihoa]

ull prob have to run 98 ron for a 1-2 tanks before it starts to show some improvement also.

[WATAJK]

BP Ultimate or Mobil 8000.
Mobil 8000 some reason pulls much better then Ultimate in my ITR but thats IMO...

Problem with Mobil is that there ain't to many of them around ..

[r3ckless]

i agree, thats why i choose to stick with BP, so many around.

Dont liek mixing my fuel.

[Neesmo31]

I know its only a dc2r, but i put in $114 worth of BP ultimate (at $1.50 basically) that got me 1100kms. $114 = 76L = 14.4kms per L on the highway. I thought that was very very good.

lol, its actually 6.9km per L :D

[aaronng]

Yes, use V-power, BP Ultimate, Caltex Vortex98 or Mobil 8000.

The reason you get high fuel consumption on regular petrol is because the ECU detects the beginning of pinging and it dumps in more fuel to protect the engine.

[Neesmo31]

Actually its what i said.

1100 kms using 76L
1100/76 = 14.47

To check, 14kms for 1L so 76 x 14 = 1100.

The 6.9 is L/100kms

I think...

my dc4 im getting anywhere from 280-380kms on synergy 6000 with a 40 litre tank
but my engine has 280XXXkms on it.....currently doing an engine conversion so im hoping the figures will be better then =]

[r3ckless]

this is regarding dc5's /k20

[Zinyo]

i've always used vpower, it doesnt burn too fast hence always gettin 500+ even under the occasional "push". I might have to try mobil and see if there's any difference...
But regardless, it depends on wether you go to a lot of stop-start traffic or not/if you're a "heavy foot" type/anticipate traffic...

Everytime you fill up, just make sure the hose is somewhat vertically down and turn the fuel handle upside down as there are always a little bit leftover fuel in there that people usually forget about...its basically fuel that are left inside the hose/handle...u paid for it so make the most of it...

You're wrong. All DC's have 50-litre tanks. Even the first gen SX16 Integra had a 50 litre tank. Check the hard specifications if you don't believe me. The fuel gauge is a little alarming as it shows empty/reserve very early on to stop optimistic people running it until dry.

Even a current model Suzuki Swift manages to squeeze a 48-litre tank in it.

Even though the AuDM DC2 is officially tuned for 95RON based on spec sheets, I go further on BP Ultimate 98RON. 95RON usually gets me around 450-460km until the reserve light comes on. With BP ultimate the car does 500km until the reserve light comes on.

[KOHO]

running my dc5 non-R on V-power. Mainly highway driving (from city to nepean hospital). full tank can last me close to 600km and the reserve light hasn't come on.

[qstoria]

So OP. In summary,

use 98 octane fuel for a few tanks and see how you go :)

ohhh ok that'll solve my problems then lol

[onesweetb0i]

OP, i have the same problem full tank i get only about 350-380 .. still can't figure out what's wrong with it, i drive normally 3000-4000 rpm and yet my mileage is so crappy..

[fabian0]

check your tyre pressures......................

That comment is wrong. I own a DC4 and DC5R. My DC4 is only a 40litre tank.

have u gotten a service yet?

Check you spark plugs also.

[onesweetb0i]

have u gotten a service yet?

yeah just got it services last week..

btw how often do you guys use the A/c? could that be the reason why my mileage is low?

[burak213]

i always use mine, still get decent mileage

[ekay1]

i think im having that problem as well i use shell v power, but the problem is i fill it up when its just a little passed half way and when its about halfway it does about 180-200kms is that normal? i change gears at around 3000-4000 vtec once or twice? so if i did the full tank would i do about 400kms? when do you guys fill up? when its almost at empty or like 1cm off that? thakns btw my tyre pressures are good and got it serviced not long ago with new spark plugs :)

[r3ckless]

btw how often do you guys use the A/c? could that be the reason why my mileage is low?

every now and then. i dont really see how a/c can have a drastic affect on mileage... liek i said earlier, i gave it a really good hit up and down RNP, and my needle said i only used 1/3 of my fuel !

[KOHO]

I use the A/C all the time. doesnt affect my mileage at all. as above, i can travel up to 600km without the reserve light , but thats highway driving.

What i notice though, is difference in where you pump your gas. Had 1 experience where I pumped V-power at Station A and only lasted 400ish whereas Station B could last me 500-600ish. Same driving style, nothing changed..

[WuackR]

Recently I've research myself with using either V-power/BP ult./98ron and other top brands and out of all these, I'd have to go with BP ultimate.

I do some regular driving including hitting the "v-tec yo" and for some reason the others seemed to burn much quicker and easier compare to BP ult.

I'm not quite sure of the differences between each of these but for me BP does me well and leaves me quite a few juice to keep me going.

BP = Best Pren :D

Back to you guys.. :)

[onesweetb0i]

ahh, last full tank only got me 330 lol .. will check out sparkplug, tire pressure on the weekend

[Zinyo]

Apologies if this is going sidetracked, but do you own a DC4 or have filled up a DC4 from an almost empty tank? I filled up petrol today from what I believe is an almost empty and can only manage 38 litres.

This answers my question. http://www.ozhonda.com/forum/showthread.php?t=101709&highlight=dc4+fuel

You can't do that and say that your tank is absolutely 40 litres. There is a reserve section where the needle is at empty but you have about 8-10 litres left at the bottom. And the thread you linked points to 50 litres.

Here is more proof that it is 50 litres. http://www.carsales.com.au/car-research/details.aspx?__Qpb=true&__Nne=15&Cr=8&R=71327&__Ns=p_Year_String%7C1%7C%7Cp_Make_String%7C0%7C%7 Cp_Family_String%7C0&keywords=&__N=2994+4294956040+4294843457+4294906418&silo=1305&seot=1&trecs=20&__sid=127498A3A102

Thanks Aaron for the further triple confirmation.

To ddcc55rr: Aaron is right, so I won't repeat what he wrote. Do I own a DC4? I own a DC2. Exact same fuel tank beneath the rear seats. Don't rely on the fuel gauge. When the fuel warning light turns on in my car, I can get about 37 litres in. When the needle drops all the way to the bottom of the scale and it looks like that's it game over, I can get 41 litres in. Then I once tried to keep going still, and the needle pretty much fell off the scale at the bottom end. (Don't try this if you don't have a servo nearby). I got 43+ litres in at the fill-up. That means that there's still almost 7 litres sloshing around in there. But if you've seen how wide and flat the actual fuel tank is, the 7 litres will be spread out real shallow, maybe 1-2cm deep, at the bottom. So if you go up a steep hill, and the remaining petrol tips to one side in the tank and the fuel pump just might starve.

But, I don't get it, why can't you accept the cold, hard specification sheet facts concerning capacity, but continue to argue it?

[onesweetb0i]

A/C does affect your fuel...especially in stop start traffic

would it effect it so much i'd only get 330-350 a tank?

[tiksie]

i always use mine, still get decent mileage

Yeah.. But you don't have a Type R.......

How many litres do you fill in for that 180-200km? THe gauge is NOT accurate. You need to fill til full, drive a few hundred kms and then fill back up to full. The divide litres by distance x 100 and you get L/100km.

[aaronng]

Yeah.. But you don't have a Type R.......











wut
DC5S = DC5R without LSD and chassis stuff.

[tiksie]

How did I know you will say something like that haha :D
Still doesn't make it a Type R mr.aaronng LOL :p

[Zinyo]

would it effect it so much i'd only get 330-350 a tank?

Well it depends if you use it excessively or not. For instance, have you ever notice that at idle with the A/C on, your idle rpm is below normal/or you can say that it is idling substantially "rougher" than without A/C (No, im not talking bout the A/C fan noise...)

With the A/C on your power slightly diminishes and it takes more to do what you want it to do...i find on my 5R that shifting is not as smooth when I have A/C on as otherwise (and I can plainly say that my car is in good condition and have always been serviced regularly with only 70k kms so no reason arguing that theres something wrong with my car).

Test it out and you will notice it - dont have your music on and i guarantee you will notice the difference, especially for us where we can hear everything anyway...lol...Regardless tho, shouldnt affect it by that much that you get 150+kms less that normal...probably a combination for you - tyre pressure + A/C + Vtec + shift at higher rpm + etcetc

[Neesmo31]

Photoshop of DC5 petrol filler neck going nom nom nom...

Still, even with bulk aircon use, it shouldnt be that bad...

[aaronng]

How did I know you will say something like that haha :D
Still doesn't make it a Type R mr.aaronng LOL :p

Similar to a Type R in fuel consumption. :p

[detasemen88]

i think it depends on where you drive the car.... mine is 02 DC5R, and i live in traffic jammed city.... 1 tank only last for 287-290 if I am lucky and it only drinks 95 RON fuel. different story if i drive out of the city on freeway. i tank can last up to 450 Km... huge difference right?

[SHI-FTY]

if your car is consuming too much petrol than usual i suggest next time you fill up your car with premium fuel add a bottle of 'injector cleaner' to your tank it wont hurt and chances are it'll resolve your problem

[Zinyo]

But u live in jakarta? its a lot different...lol...everyday macet and A/C is on all the time

[detasemen88]

Correct Zinyo...... my car is daily driven..... but hey petrol is dirt cheap in here..... only Rp 7300/Liter or less than a dollar for 95 RON........

[RED-DC5R]

Tire pressure, 32 psi but for me i like 34psi. Myabe cus you have windows down which causes drag. Take out the spare tire its 15kgs makes a abit of a difference and lose some weight lol

[DC5-S]

Wow, i only get about 400KMS from a 40LTR tank of BP Ultimate......

[mrntegra]

my type S if i drive it down highway for week of work can get me close to 700kms... if i was to fill up and drive around town ill get about 450-500 and i've only ever used shell v-power
