View Full Version : 98 vs 95 octane for my R

25-07-2005, 04:34 PM
with recent fuel prices being the way they are, I was thinking of trying 95ron in my DC2R for a while and seeing how it goes as the recommended fuel is 'premium unleaded' which afaik is 95 and above.
does anyone here run their Type R on 95 on a regular basis?
if so how do u find it? ie. response, fuel economy ect.
No No No No!!!
stick with 98.
dont ask why just do it!
It's prolly fine..... but I'll be sticking to 98 octane.

ive only had mine for a week and so far running it on 95, ive done about half a tank and done nearly 300k's, still goes pretty hard. doesnt seem to effect performance that much, but as i said ive never run it on 98!

98 all the way!!!! used to put in a bit of unleaded fuel and what i notice is top end power around 7000 rpm it pings, but i always use 98, i say if you can afford a R what's $1.25p/l??? hehaehahe

You'll probably notice slightly better economy out of 98 fuels anyway (btw, BP Ultimate ownz all other 98 ron petrol). Also, BP Ultimate (and the others) contain stuff to keep your engine clean aswell.
P.S. I have a DC2 VTi-R and I would only put 98 ron into it.

Think about it like this if your too tight on spending the extra cash.
The next time you go and have coffee with your friends just don't have anything, that'll make up the difference.

may i ask how did u manage close to 300km and still not 1/2 way through ur tank? or did u mean ur odo is close to 300km?

What kinda economy do you get? I'm still yet to run the numbers on my car but 300kms to half a tank sounds about right, if he babies it. Although his is a Type R, so there's gonna be differences there.

if u want to save money in short term use 95 ron, if u want to save your engine in the long run and have piece of mind use 98 ron.

Don't worry I'm not doubting those numbers but I find it normal. Most I ever got was 380ks out of a full tank and I drive pretty normal tho, change gears bout 3000rpm, but no highway driving.
btw: stick with 98 better for your car. Performance wise, is the difference really noticeable? And yea, if you can afford a type r and the insurance, what $1.25 per litre gonna do?

If you're SO worried about economy, use 98 ron, but just don't let your car rev over 4,000rpm. :P

u serious...? somethings wrong wit ur car then...... I usually get about 550kms from full tank

i get about 400 km to a tank in my dc2r...its farily worked though.
And with the thing about expensive petrol?? just skip on eating junk food for a few days of the week...theres your petrol money right there!

ive only fanged it a few times on this tank, most other times i have the gf in the car and she spits everytime i fang it! its running close to 300km at the moment, i got it with half a tank and did a little over 200k and then filled her up, with just under a quarter to go! but i think i might run 98 next time round to see the diff. 98 here like like 1.35 p/ltr!

damn where the hell are you from??? the bush land??? hehaehaeh that's really high!!!!!, catch a bus or somethingh might be cheaper heahehah, but yeah use only 98, you pay for what you get, like most ppl said its better in the long run :D

DARWIN man!! its highway robbery!! BP Ultima is the only 98 we have and only 2 places sell it!!

zorrt, see your PM. Your car might be stuffed (theremostat?)
Anyway, I've noticed not all 98 rons are created equal. Before I got my thermostat fixed, I was doing about 100km/10ltrs on BP Ultimate. I tried Shell Optimax, and got about 70km/10ltrs.
I allways found my old crappy Lancer ran better on BP Ultimate than on Shell Optimax too (when you have a rough car like that, you figure out fast what is good and what isn't).
Now that my thermostat is fixed, I'm gonna try Shell Optimax again to compare the economy. Personaly I wouldn't put it in my engine, 'cept I'm curious. As far as I'm concerned Ferrari can keep their smelly petrol.
i thought that 400km per full tank (40 litres) was normal for an integra... if not, then what is?

i get 550 easy from baby driving and 450 - 500 from fanging it
BP ultimate. My car has 125k on the clock
type one
25-07-2005, 05:23 PM
i NEVER got 550 on a full tank in my R... 420 MAX... this was using optimax.
I was a leadfoot and the car had I/H/E and non-progammable ecu. 550 is massive.

Not babying my car at all, it's done 369kms on just under 3/4 a tank of petrol so far.
I'll have a better idea of it's economy once I've owned it for longer than a month. lol.

im doing a test at the moment with my stock vtir
checking out which petrol is the best
done 3 weeks of bp ultimate getting aruond 8.5L/100Km thats city driving
going to try mobil 8000 for the next 3 weeks, shell optimax next after that caltex
then (another other i missed?)
then ill try the 95 octane ones of each company... ill post the results when im done...

um isnt the standard tank size for an integra 50 litres. Or does GSI have 40 litres. My Vtir definately has a 50litre tank.

50L? serious? Most I've ever poured was under 40L and that was when the petrol lights were blinkin and thats full for me already. Would that be why I'm 100ks less than the majority of you out of the car? So on average I do get ~$11 per 100km.

but when the petrol light blinks doesn't that usually mean you have about 80kms left of that tank?? i think its called a reserve tank or something..

only reason id use 98oct in a car with stok ecu is to keep it clean, octane would make jack all difference to performance unless u had your ecu tuned to run 98 then ud have to use it all the time

On return from Melbourne after purchasing my car I was averaging about 4000rpm most of the way following my Dad in GT Liberty included a number of tandem 4-5 car at a time overtaking manouevers (read: not really babying it) with A/C on most of the way managed about 620ish, 650 definitely possible with lower rpm. Only run BP Ultimate 98ron. Subaru however did 850 easy with 60L tank and lower gearing helping too.

mmm... yeah i only get about 400 out of a tank in my R. wish i could get 550!!! that's huge...

locote, your car should run slightly better with the higher ron petrol. It should also give you better economy.
stormridah, I'm also comparing BP Ultimate, Shell Optimax and Mobil Synergy. So we'll have 2 different stock VTi-Rs results to compare. That'll be good.
And guys, comparing how far you get on "a tank" isn't so great. Try figuring out how many ltrs it takes to go 100kms. It's much better to compare that, as some people call there tank empty when the light comes on, others say it's empty when the lights been on for a bit, others still say it's 'empty' at about 1/4 full (which is when I usualy fill her up).

Consider this an educated guess, would've been running on the smell of fuel alone in the end.
isn't running until ur car is totally empty bad for ur fuel pump?

Yea it does, not sure how many k's you still have left to travel tho but I've never ran the car till it clonks out. The only reason why my light started blinking cuz I was being tight and didnt want to refill the tank since petrol prices was too high :] And yea I was told it was bad to drive until the lights starts blinking, but not like I do it that often.
I guess the distance I get out of my car per tank (even if if I havent measured it the most efficient way) sounds about right then.
So is that 45L tank applicable for all DC2s? If so I'll try to get a proper measurement of how many petrol my car uses.
To the guy who started this thread (sorry we hijacked ahhah) moral of the story is, stick to 98 :D :D :D

Sorry I didn't make it clear, I wouldn't literally run it that low, just for illustrative purposes. I imagine all the crap floating at the bottom of your tank would go through the pump, but pump should handle it I think, just ensure fuel filter is in good condition.:thumbsup:
Well most have you are getting pretty darn shit feul economy of only ~400kms per tank...., thats more then 10L per 100kms! should be getting around 8- max 9L per 100kms.

Agree, or even less is quite possible.
my car is due for a service very soon... do you think that this will at all help with the fuel consumption issues?
...its only due for a minor service, but i was thinking to get a semi-major one done anyways.. just to be safe
Yeah it may help, clean airfilter will improve, make sure timing is right, fuel filter etc....

I'm guessing you guys will be lacking performance too. If your cars are running rich (and I don't see how else your economy would be that bad) then you're not gonna be getting the most out of your B18C.
Another full tank of BP Ultimate last night. ;) got 426kms from 33ltrs. 7.7ltrs/100kms anyone? And like I said, I don't baby it ('cept when it's cold). I did do a little country driving though up to my mothers place and back (about 160kms round trip, but not all of it was country).

Yeah that mileage sounds very similar to mine, I only use BP Ultimate.

Hey I measure my economy yesterday. With Vortex 98 I'm got 90km out of 9.42L of petrol so thats not too far off I guess but might just service it anyways to see if it can be improved.

27-07-2005, 06:33 PM
after working at a Caltex service station for over a year now...many people coment on the advantages of vortex over BP Ultimate and the other premium 98 octane fuels. I do believe that vortex gives better milage and looks after the engine well.

hey ppl tell me BP ultimate is the best! But its so bloody expensive. BP has three levels 91, 95 and 98.
I've noticed shell optimax is usually a bit cheaper and is still 98 octane, they only have the 2 levels 91 and 98. Does anyone know if there's a difference between the two?
Anyone have any opinions on the best brand of 98 octane? or are they pretty much the same
typsy
28-07-2005, 12:08 PM
Shells now have 3 levels: 91, 95, 98.
I reckon they all almost the same as to performance and mileage.
Just personal perference. I perfer Shells Optimax.

28-07-2005, 05:35 PM
sif use 95 ron fuel u tightass
fkn use the good shit or go buy a car which doesnt need premium
pplz complain they cant get 100 ron and u wanna use 95 when theres 98
BAHH -_-

stick to one fuel .. never change around
my personal opinion .. stick to optimax or other ones like the mobil high octane
