Optimax - Where Did It All Go???


Recommended Posts

Be very carefull using octane booster instead of 98 octane fuel. When it says on the octane booster bottle that it raises the octane level by 4 or 5 octane points that means .4 or .5 of an octane ie if you fill up with 95 octane and add an octane booster that raises the octane level by 5 points then the result is 95.5 octane fuel.

Still well below 98.

And double dosing isn't the solution either. Octane booster is designed to work in a certain ratio adding more than the recomended amount will no doubt increase the octane rating a little further, but a double dose doesn't raise the rating twice as much.

I learnt this the hard way. Luckily I only got audible detonation not detonation induced block ventilation :Oops:

i use octaine booster with ultimate... just want to see if it makes a difference, the 1st time i used it i noticed it but the second time i used that nos in a can sh!t and i didnt notice n e thing, i cant remember what i used the 1st time

This is from a Shell employee who recieved a memo last nite while he was at work...

The Sydney refinery has broken somehow so Optimax and LRP will not be delivered for 2 weeks.

He isnt sure wether the new delivery will -arrive- in 2 weeks, or it will start to be shipped from the refinery in 2 weeks. Obviously what he told me isnt word for word what was in the memo, but it explains why Canberra has run high and dry of Optimax, and BP Ultimate is getting pretty low too (since everyones using that with no Optimax availible).

Doh! :rant:

"Shell Optimax out of stock.

Due to circumstances beyond our control, Shell is currently unable to supply Shell Optimax to all sites in NSW, ACT and Vic.

We aim to be back in stock from the 24th of November in Victoria and 27th of November in NSW and ACT.

Please accept our sincere apologies for this inconvenience.

I couldn't find any optimax either, I went all the way down Pennant Hills Rd.

what about going to Bankstown airport and buying a 205ltr drum of Jet fuel, supposedly its only around $1 a litre and put in a couple of litres every time you fill up. That should boost up the octane level and give you more power to....

Hi Guys,

Just some quick replys.. Cheers Poakey for clarifying the Octane booster issue I had. That would explain why my try at using Caltex Vortex + Octane booster didnt help. What a waste of $10 bux or however much it was. VL-TRBO-RB20, it wont work.

SW20-GT it would be fine if there was one in my area.. I will be trying to find a BP servo soon.

Interestingly, I was told that BP actually buys its fuel from Shell anyway.. Must have different storage facilities..

rrrage thanks mate thats what I was after.

Called up Shell at Dural this arvo. The guy said they'd be out for 2 weeks. So that confirms the Shell refinery problem.

I thought they had that fixed already....

Anyway, filled up with BP Ultimate instead today. 108.9c/litre..... not too bad.

wil..

    • My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.
    • Fark the AFM card and Nistune, Haltech Nexus S3, DBW, cruise control, flex fuel, dis dat.  
    • It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.
    • Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!
    • Should have taken that opportunity to slot in a twin scroll turbo setup. Maybe next time.
