it should be fine... the ECU will retard the timing... BUT the user manual states a minimum of 95RON... so take it easy this tank... and just top her up the next fill with Optimax/Synergy 8000/Ultimate.
is there a certain amount of octane that needs to be to met for EK4?
errr..cos i never know about this..and i got my car second hand..i dont have the manual..
i've got normal unleaded in my car now...
if i fill up with BP GOLD ultimate, what will happen? better performance?
just start using premium unleaded petrol
of better yet the 98 octane onces
it is better for the engine
unless you have a missing sticky it would say what type of fuel you should fill up -> located behind the fuel door flap
:eek: which part on the sticky -> you guys don't understand :eek:
---------------------- :D :D :D :D ---------------------------
If you stay under 4000rpm you should be fine.
what if he puts in 98 octane, will it kinda mix to create something inbetween? haha.
lol....
u guys are like adement that he needs to stay under 4000rpm seeing as he is using 91oct. does anyone actually know the facts of this? or the negatives of this? the theory behind higher ron?
this is just all hear-sai.
...your ECU still thinks its running with 96+octane fuel...so in the danger of leaning out high revs etc I would drive like miss Daisy ( ie SLOW and dont "veetech yo!") until empty - THEN fill it up as normal :)
Dont do it again :)
Add Some Octane Booster If Ur Worried!!!
i use 91octane Shell or BP,98 is toooooo expenisve these days.
my car seems fine?
Yeah my car has a sticker on the back of the fuel door that says Premium Only ;)Quote:

But 91 Octane isn't premium, 91 octane is only standard unleaded. The B16A2 needs at least premium unleaded because of the high compression. Besides, even if the premium fuel is 10c/L more and you use 2000L/year, thats only an extra $200. Be kind to your sol! :pQuote:

I put a booster in my car and fould my plugs... 3 times.
whats the best 98 to use? optixmax, synergy 8000 or BP ulitmate.
theres no one best fuel... its what works best with your car, but it seems B16a's run better on Ultimate.
Seeing as my '90 SiR is rated for 98 octane, the big 3's 98 is all that goes in it. Given that the EK4 VTiR's B16A is an ancestor of my gen 1 B16A, I'd be guessing premium is the only way to go to protect the motor.
Knock knock....Quote:

You are shittin' us with that comment right?
I found that the Synergy 8000 was nicest - but I use Optimax as I can get the 4c discount with Coles dockets :DQuote:

So even though it says in the manual and on the fuel door to only use premium, you're telling him to use normal unleaded? I don't get it. The B16A2 is a high comp motor, designed to run on 95 and above. Why would you bother putting in anything less? :confused:Quote:

Honda may be stupid with marketing but not with engine design. Why do you think the ausy B16a are detuned from the JDM's... They've taken into account for the idiots out there who just dont care.
Well getting back to u guys on this... managed to CLEAN the tank out... basically drove it until it was like no fuel left...and then left it running idle at the petrol station for ten minutes (i bought a magazine) while occasionally revving...
then put in BP ULTIMATE... u wouldnt believe the difference... its altogether a different car...
my advice is that if u want to enjoy ur car, put in the fuel she needs... but if ur strapped for cash, then yes 91 OCTane is fine... i asked my mecahnic and he said exactly wot u guys did... my ECU has a knock sensor...so it basically slows the whoeleeeeeeeee car down when u put in 91 oct... the only "bad" bit is the dirt, which can easily be cleaned with a tank full of optimax..
Why are the aussie spec B16A motors de-tuned from JDM's? Because they have 100RON fuel, our premium is only 95-96RON. :rolleyes:Quote:

From what I've been told their regular is 96-98, so they dont need to compensate for idiots/lazy/poor barstards that dont want to put premium in.
If it was such an issue Honda Australia would have left the tuning at 98. But no, they compensated by lowering red line and tuning for 95. Remember they could have left it at 98. But they know that would comprimise the engine too much as not only enthousiasts would be buying the car, and it is enevitable to get someone who puts 91 octane in. Make sense?
But the thing is, there was no 98 octane when the B16A motor was first released in Australia. 96 was the best grade you could get back then, so Honda had to detune it to run on our crappy premium.
Not really there was 98 octane in 96.
Yeah but the B16A has been around a lot longer than that...Quote:

Too stupid to realise the diffrence between two fuel bowsers that say "Unleaded" and "Premium"? Even when it says "Premium Only" on the fuel door? Would somone this stupid even be able to drive a car? :p

ECU-MAN is 100% right, theres some real ding dongs out there.
Theres seriously some idiots out there who would be like... yeah thats just a recomendation, its JUST petrol... not like it'll do any damage... what could go wrong. get what I'm saying?
Lol, people like that *deserve* to have their engine blown up :pQuote:
