Looks like there will be supplies from today although it will take a while for all the deliveries. I wouldn't worry about booster it you only put $10. Presumably your car had some 98 ron still in the tank (ie it wasn't dry). Even though the car has a knock sensor perhaps keep the revs under 3000rpm until you can fill up with premium.Quote:

my car is not going or doing anything.. taking the GFs car instead
With no Ultimate stock in Perth I have run on 95 ron Shell today.
It is definately a step down from Ultimate - whether it is the ron, detergents I don't know (does it matter?). Mr Will I wish you had a Euro to feel the difference - it is definately there in responsiveness.
well all i know is that all Vtec engins should run with premium coz of its timing so how would you run it on standard unleaded .......

With proper DOHC VTEC, the change in cam timing is fixed when you pass the VTEC cam change point. So even if you retarded the ignition timing, the cam timing would still be advanced. Since Hi-cam advances cam timing to enable the intake valve to open earlier and for longer, you get better filling but coupled with a quicker compression stroke from high RPM, thus resulting in higher temperatures that can cause the mixture to prematurely ignite before the engine was anywhere close to sparking the plugs. So for DOHC VTEC engines that have high compression ratios of above 10:1 and make close to 100 hp/litre, it is still advised to run on premium unleaded even with retarded ignition timing.Quote:

giddy up ultimate 98 is back in wa
Today I had no other option then to fill my car with 91 RON @ a BP station.
Ever since day 1 of ownership I have only ever filled it with 98 BP Ultimate, I can tell you for sure that Its worse thing I have ever had to do to my car internals!
The car feels sick put $10 worth in. Now need some 98RON! Just goes to show at least for me what 98 RON does for my Euro.
The Caltex near my place did not any premium petrol last night, I had to try Shell. Lucky I got some. Don't know if it is the same thing happen to WA a few weeks back.
Why didn't you put in 95 octane instead or go to another station? There are heaps of petrol stations with 98 and 95 in sydney. It's not like you're in the countryside where there are only 1 or 2 stations with premium.Quote:

I was in the middle of nomansville LOL! There was no 95 RON and had the low level petrol light on.Quote:

Since then I am now back home and filled her up with some BP Ultimate.
Will give Mobil a try and perhaps even the new Shell 100RON
Ahhh... that's good news. With the 6MT, I've been able to go about 80km after the light is on. Can use that as an estimate of the remaining range next time.Quote:

Thanks for that info aaronng there was just a pub and a BP Service Station there as for women no but alot of beer :p ;)Quote:

Yes we have read it - doesn't mean it is right.Quote:

And you have tested the car with BP Ultimate and noticed nothing different?Quote:

The APEXI RSM with G sensor records consistently faster in gear times with 98 ron fuel on the same road, same temp. So no launch issues to stuff times - ingear. That is a better test than your theories.
If your response is the rsm is inaccurate, what were the test conditions, air temp, fuel load - etc. Don't bother. You are not interested in anything other than your "technical facts" (which BP says is wrong) so why should I bother.
Guys,
Have been following the debate - too techincal for me.
For my part I have alternated betwen 95 and 98 (over two years on a weekly basis) and noticed no improvement in economy when using 98. however, the Euro seems to go better when using 98 - especially going up hills. I drive a stock standard Euro (no mods) and it is serviced by the dealer (so presumably no frills standard factory setting tuning).
I notice that Shell has introduced an Optimax 100 (contains ethanol).
Has anyone tried it? Is it safe for use in the Euro?
Honda has issued a statement that the Euro can handle up to 10% of ethanol. Optimax 100 has 5% so it should be alright. But I'm still not going near the stuff. Especially since it is more expensive while independent stations are able to offer ethanol blend 98 at lower than 95 prices!
handle with no adverse consequences in terms of engine life, performance, fuel economy etc?Quote:

I'd guess that 10% would be alright for quite a few years as most manufacturers try to build their car/engine to accomodate as many conditions/fuel as possible. But for me, I'm keeping my car for the long term, so I won't be using any ethanol blends yet. In the future if ethanol blends become mandatory, at least I would have tried my best in minimising exposure to ethanol.Quote:

If they offerred the ethanol blend at the same price as 98 or cheaper, that would be more enticing. :)
MELBOURNE CREW...
Does anyone know anything about that fuel "Boost 98" that's available from that service station on Kings Way in Melbourne? (The one with the Hungry Jacks)...
i can felt the different of optimax and 91 regular even my friend didn't didn't told me his wife put the wrong fuel, until i asked...91 regular put into honda Euro can be desribed as "wild bow tighted with string", you can felt loss power very obvious.
91 octane in the Euro is a no-no. I hope your friend had put in 98 octane as soon as he could to increase the octane of the fuel in the tank of his Euro.
I have no clue why anyone would even consider using 91 octane unleaded when the sticker on the car clearly says to use 95 octane AT MINIMUM.
Before the euro i owned a hyundai excel - and i could feel the difference in that when i cheap fuel was used as opposed to shell / BP...
As for the euro i got slightly better ecconmy with BP 98 than BP 95 - i only get 98 due to its clensing properties....
I still dont quite understand your argument Mr Will - We are talking about little minor adjustments to timing which in the grand scheme of things really means stuff all on a stock motor car - i doubt many people would acually feel the difference between 140kW and 150kW let alone 140kW Vs 139.5kW if infact your argument is valid (which i can see no reason for there not to be)... Say i do loose power - i'll spend 30 mins indexing my plugs and i will have it back again - more than one way to skin a cat :)
im pretty sure most people will be able to tell the difference between 140kw and 150kw...if you cant, then by all means dont bother advancing your timing.Quote:

i dont know what youre talking about with 'indexing your plugs', can you please explain this further
Indexing you plugs involves placing washers under all/some of you spark plugs so that the gaps all point in the same direction - a little towards the intake valve... its easy enough to do just mark down where the gap is with a marker and screw the plug in - if the mark (gap) doesn't point a little to the intake valves put a washer under it to make the spark plug thread a little shorter... add washers till all the marks are in the same position and you are done :)
Its an old school v8 tuners trick to get a few extra hp - just helps to achive a more complete burn in the combustion process - i've seen a 2kW increase out of a turbo car by doing this :) You can do it in your driveway and take a punt but a dyno is the best way as you can see the effects of different positions to obtain an optimal result :)
