today i put Optimax (well the Shell equivalent which is V-Power) into my 2nd gen, seems to be running nicly, a little smother and the gear changes are a little easier than what happened when i put the Pod filter on (when i put the pod filter on there was a small amount of lag in the auto gear changes, now its barely noticable) and yeah - i have only done like 100km today with the V-Power in there... spoke to Ashneel about it and he said i will really notice it in 2 weeks.

Anyone have any input? you use it? think its a waist of money? think its better than sliced bread? anything?

i think ill keep using it, even tho its a bit more expensive...

cheers,
Tristan

Keep with it mate
No use spending $4K ona car if your gonna feed it crap.
For an extra $5 a tank i think its well worth it

It's well worth it for 2nd gens as it gives you a little power boost and with my TR i actually ended up saving money from better fuel economy even though you pay extra at the pump.

:stoopid: yeh man its awesome stuff, stay with it. went back to normal for one tank, hated it. couldnt wait to refuel lol.
btw theres 2 V Powers: V Power (98) and V Power Racing (100) :D

careful - Shell's 100 octane is 5% ethanol.

hey hey, I tanked up with V-Power today too! -on way home from TFTR

I've been using ethanol blended petrols for ages...they will not cause and problems with our cars.

Yeh they're fine! But a tank of ethanol blend seems to get used up faster than plain petrol. Anybody else experience this? or am i smokin **** again...? :P

i think it depends how munch crap you have in your tank, a few mates with there cars they use that 10% ethonal stuff and they reckons it goes through like nothing else for the first couple of tanks because its cleaning as it goes.


But personaly i use BP Ulitmate, i've been using it in my car for about a year now and i have no problems, the only times i had problems with it was when dad put the wrong fuel in (bloddy Woolworths/caltex :rant: )

nah i can't use that ethanol stuff...
the v6 absolutely craps itself.. starts stalling and revving strange....
but the 98 BP is good stuff i use that 3 out of 4 tanks..

Yeh i started using the better fuel and i seriously get more milage out of a tank and a tad more exceleration. but it does last a tiny bit longer.

yeah is better but i couldnt get traction on take off with 98 so went to 95. now it only brakes traction on medium hardness take offs. plus i get an extra 80kms on the whole tank with 95 than normal

Smokin crap :P

I was using ethanol back in the SOHC 12v 6G72, it ran fine. No better or worse, just the same as it always had.

ADZA27, that's really wierd...I've never heard of anyone else with that problem.

ADZA27, that's really wierd...I've never heard of anyone else with that problem.
Add me to that list, ran like crap on my TR and on my TJ, so i try to stay away from it :).
And yeh i don't get as many kms on ethanol either but that may be due to my engine not liking it. I've heard first couple of tanks can cause this and then it straightens out, i didn't wanna keep using it to find out :).

well when you stall halfway thru a round about and ur steering locks up... OH F**K
i ran 1 tank only by accident (mum filled it up...)
and never ever again...

I use the ethanol stuff now and again, but yes, it does seem to burn slightly quicker.

Apart from that, its 91RON for me :) Rather spend the $5 i save on smokes than pretty petrol for my car.

i can already see that its getting me more kms coz ive just done 1/4 of a tank and im up to 150kms :D
just got my wheels balanced too, so now no more shaking over 80km/h! yay!

Smokin crap :P

Fair nuf lol .

Heh... nah the car runs really well on it... just seems to use it up quicker for some reason. I've tried 3 tanks of it.. roughly 60-80km per tank less each time. :confused:

yeah is better but i couldnt get traction on take off with 98 so went to 95. now it only brakes traction on medium hardness take offs. plus i get an extra 80kms on the whole tank with 95 than normal

lol dude, you might have to change your right foot work, that"d be minute changes in torque and your getting wheelspin.

I only ever use 98 octane ultimate, never had a bad batch. Have had a bad batch of vortex so no more, also ran the ult before i had the car tuned ran alot smoother on idle and torque was more consistant.

My sohc didnt like ethanol either

dunno mines always span wheels even with 2 thousand revs and half dump it does them. cant say im dissapointed bout it. makes me think of peter griffings laugh when i do it

I have a TS 3.0, and I use Shell Regular. But I also add Flashlube Injector Cleaner as well.
1mil of Flashlube = 1 litre of fuel. I just bought 1 litre of Flashlube that will treat 1000 litres of fuel, and that cost $16.00 (0.016cents litre extra). I only do city driving in Sydney, and I have had no idling, starting or performance problems. I make sure I use my Coles 4 cent discount shop-a-docket, and fill up on Tuesday afternoons,which is the cheapest time throughout Sydney.

That's fair enough...I wouldn't either :)

I was using ethanol back in the SOHC 12v 6G72, it ran fine. No better or worse, just the same as it always had.Ditto. I've been running on 10% ethanol for almost all of my refills for probably the past year or so, and it works brilliantly (SOHC 12v 6G72). I get at least the same performance and kms as standard unleaded, I would say I'm actually getting better than standard, but it's hard to quantify when there are so many factors that can affect either.

But to me it feels like I've got more grunt :D

ADZA, as KB said, that's really weird, are you sure it wasn't something else, like you had just had the power disconnected and the ECU hadn't retrained itself? I've had similar experiences in such instances, the ISC hasn't been trained to adjust properly, and under idle situations with lots of load (slow cornering: power braking and power steering kicking in), idle has dropped too low and stalled.

On that note, as a side point, when I have disconnected power for a while, I now have a sort of "fast training" method for getting the ECU back up to speed, basically you need to take the car through all sorts of load situations and sudden changes, eg., accelerate then brake heavily, brake to 90degree turn, run aircon at idle, run high-beam at idle, and various combos of these.
Obviously not to be done in traffic!

hahah that makes me think of brian hitting peter in the head and saying "no" (when peter doesnt tell the truth to lois about welfare i think).

ask KB DOHC @ 2krpm + half dump = burn out, i have to guess where 2000rpm is but i'd be pretty close.

Put the good fuel in and lighten the throttle:D

lol I showed my mate that it'll spin with 1500rpm dumps. He was surprised haha.

in the wet just clutching will do it when im stupid and dont use accelerator. im so damn lazy with the manual its like rev change rev change barely thinking what im doing. anyway would using higher octane fuel wear out your spark plugs faster?

would using higher octane fuel wear out your spark plugs faster?

i doubt it, knock sensor and O2 sensor working to keep your combustion at a suitable temp (through a/f ratio). Also generally cleaner fuel would be better for all internals; not sure myself.

nah i can't use that ethanol stuff...

but the 98 BP is good stuff i use that 3 out of 4 tanks..
I can vouch for that. Ethanol is no good. Car seems to have so much more lag off the line even with the supercharger running around 8psi i can notice off the line it's crap. Just tried it out today to see what it's like.
Usually, 100% of the time (cept that time i was taking the picton road detour from wollongong with the mrs and had no fuel left and had to use premium at a country servo) I use 98 octane.
Definitely better power in N/A or forced induction 6G72 :D
Not too sure about fuel economy, seems pretty much the same for me when using 98 and Premium.
But yeah! 98 all the way. Have to keep our engines running super clean :P

It takes around 2 weeks worth of driving and filling up to start noticing a difference if you're converting from standard unleaded, but you should notice power gains instantly!

its so much smoother, i like it :D

its so much smoother, cannon has a different pitch note, gear changes are smooth, acceleration is better, i like it :D

yeas i agree with you, and it cleans as it goes does'nt it, i took the spark plugs out a while a go to check them and there good as.

i wish we could get the quality of japanese fuels isnt it like 115 or something like that?

Add another bottle of octane booster with ya 98 octane;)

Imagine how much it'd cost per litre. I know racing fuel is around $5-$6 a litre as I did servicing at the Australian Rally Championships in 2004 at the Central Coast. So i was curious and asked how much per litre racing fuel is haha :shock:

Octane booster is okay, but it only works for one tank doesn't it?
Wonder how much gains it would get?

I remember seeing 20L cans of 105ron for $40odd & 115ron for $60ish.. but that was probably 6-12months ago.

Damn that's cheap
Where was this?

']Add another bottle of octane booster with ya 98 octane;)

It doesnt work like that
Hmm, that was my understanding...
Like add octane booster to what you already have?
so if you started with 98, and added an octane booster that raised it 6-8 points, you would have 104-106RON fuel?

thats what i thought 2, how else would it work? the only reason i havent tried it yet is coz i was told it'll make the engine run to hot???
wtf japan has a ron rating of 115????

Yup and they've also scrapped the 206kw limit as well.

How does this octane mama work? :D

i found that if i used 1/2 tank of 91 ron and 1/2 tank of 98 ron
gave me more power than 98 or 95 alone

It doesnt work like that

Exactly.. adding pure octane booster (none of that octane boost & fuel clean ****) to 98 ron fuel will probably only raise it to around the 100ron mark.

95 => 97-99
91 => 93-95

Also remember, fuel is not always the ron it is quoted at. One week 95ron quoted might actually be 94 or 93 or even 96 (etc). Same goes for other ron fuels.

Another thing to take into consideration, the octane boost bottles say they boost up to 8 points... of which are probably not measured in ron. Could be a number of other ratings (mon, pon).

i found that if i used 1/2 tank of 91 ron and 1/2 tank of 98 ron

See.. i usually use 1/5 of a tank of BP 91ron, 1/5 boost 98eth, and 3/5 shell vpower and that gives me heaps more power. :D I mean its that powerful i cant control my wheelspin.
Also sometimes i like to add a bottle of octane booster (usually only before racing exotics) just to get the edge over them. :cool:




(Sorry couldnt resist...)

in simple terms (chemistry is fun fun fun)

octane boost reacts with the heptane (7 carbon atoms chained with hydrogens coming off them depending on isomer) in fuel and adds another carbon atom to the end to make it octane (8 carbons with hydrogen coming off of them)

octane boost doesn't not react with the octane in fuel. adding an extra carbon to octane produces nonane. i'm also pretty sure it doesn't change the isomer (type of octane/heptane, some isomers are not desirable in petrol as they will pre-detonate, etc etc)

octane rating is a percentage of Octane vs Heptane in fuel. RON or Research Octane Number is a rating given to fuel by testing the fuel in a engine and analysing the data. just some marketing ploy to make people by the fuel.

my idling seems to be a bit rougher and bouncier, that ment to be like that?

Yeh they're fine! But a tank of ethanol blend seems to get used up faster than plain petrol. Anybody else experience this? or am i smokin **** again...? :P
yeah i have heard that too mate

So from the sounds of it, octane booster gives you an extra 100+kw atw? HAHAHA :bowrofl:

I'm interested in buying one of these seat-of-the-pants meters you are using...

put that pro strength in me car with BP Ultimate 8000, but seeing as i cant rev the car much doesnt look like i'll be using its "potential"
wewp car just got its 5th head gasket:)

well, it goes so thats a start!
Just gotta baby it for a while, and in 3 or so weeks we'll see how the oil situation goes :)
