Bp Ultimate Running Out.

[Br4nchi3]

Vortex isnt 95, most normal premium petrols are 95, vortex is 96, ultimate is 98.

[rev210]

I just grabbed some toluene today and mixted it up with premium BP. Works better than ultimate ever does but, costs a little more sadly.

[caminperth]

mix ratio rev?

[Butler]

BP east perth still has some. They filled up for Rally Australia.

<{POST_SNAPBACK}>

thanks dan! got the last 4 ltrs there stupid guy in an ss filled up just bfore me

[dan_the_man]

what a poof

[caminperth]

dammit. was going to head out there..

looks like 91 RON mobil fuel for me.. if you're going to go bad - may as well go cheap too!

[noise]

I checked myree and it was out, then checked super cheap for some octane booster and they only had the crap stuff.

yay more wasted fuel

I think some vortex and decent octane booster shoudl do the trick once this half tank runs out.

[Josh]

yeh rev what was the mix ratio???

[KeeFy]

Might consider tolulene too, josh u post whore! =P

[rev210]

The Mixture is really dependent on how much you want to muck around with the engine tune. Toluene is less volitile and so tends to have cold start issues at low temps (after today it looks like theres no chance of that for a while).

For a straight replacement of bp 98 to drop the 'ping' factor, run around with about 10- 15% with a 95/96 octane fuel.

I run upto 30-35% for short periods. It cleans out your fuel system while its at it too. This requires a tune to suit.

There are probably others with experience around who might like to share their prefferences too.

The price for a tin is actually $32 now. Diggers brand. For a 20L drum it's $97. If people like to they can shop around for a hardware store willing to get it in regularly at a better price in my opinion the hardware store is charging abit much since they changed from being a Makit brand store.Even at $32 I preffer this over the 500ml octane bottle no brand comes even remotely close.

appart from more power. Toluene will increase the exhaust temps a tad but, it's lower volitility means much increased tollerence to pre-ignition. You run it a little on the rich side of 11:1 to be safe if your a backyarder playing with timing.

Oh and the catylitic converters don't like this additive for very long periods without appropriate tuning.

here is an old extract I have about it;

Toluene is a pure hydrocarbon (C7H8). i.e. it contains only hydrogen and carbon atoms. It belongs to a particular category of hydrocarbons called aromatic hydrocarbons. Complete combustion of toluene yields CO2 and H2O. This fact ensures that the entire emission control system such as the catalyst and oxygen sensor of your car is unaffected. There are no metallic compounds (lead, magnesium etc), no nitro compounds and no oxygen atoms in toluene. It is made up of exactly the same ingredients as ordinary gasoline. In fact it is one of the main ingredients of gasoline.

Toluene has a RON octane rating of 121 and a MON rating of 107, leading to a (R+M)/2 rating of 114. (R+M)/2 is how ordinary fuels are rated. Note that toluene has a sensitivity rating of 121-107=14. This compares favorably with alcohols which have sensitivities in the 20-30 range. The more sensitive a fuel is the more its performance degrades under load. Toluene's low sensitivity means that it is an excellent fuel for a heavily loaded engine.

Toluene is denser than ordinary gasoline (0.87 g/mL vs. 0.72-0.74) and contains more energy per unit volume. Thus combustion of toluene leads to more energy being liberated and thus more power generated. This is in contrast to oxygenated octane boosters like ethanol or MTBE which contain less energy per unit volume compared to gasoline. The higher heating value of toluene also means that the exhaust gases contain more kinetic energy, which in turn means that there is more energy to drive turbocharger vanes. In practical terms this is experienced as a faster onset of turbo boost.

have fun...

oh and it's deadly poison and you'll all die die die !!! HA HA HA!

[KeeFy]

Thanks for the info! I think i'll grab some soon! Errr... I think quite a lot of stuff are poison if u injest it! hahahahahaha

[damono]

Is there any octane boosters that you guys recommend. Also.. how much do I add to a full tank of petrol, do i go the premimum + octane booster or just get the shitter commoner fuel + octane booster. Just wondering how much I add to bring it up to, or better than ultimate 98

Comes highly reccomended by a few garages. How good it really is, i don't know. I put 1/2 a bottle of yellow into my tank for the purpose of injector cleaning, but i don't feel any difference. LoL. Cause for all u know, it just the garage pushing their product (they stock it), and when they stock it, high chance they wanna earn ur $$. But hey, it's made in WA! Supports WA! LOL!!!

[Josh]

Haha

I heard some info about it rotting fuel lines - what do you reckon rev?

[J_R32]

bp along orrong rd (pretty sure the is only one heading towards farmer freeway) has ultimate, and so does bp in bullcreek along perry ave..and u can save 4c a litre there too wif dewsons or supa valu dockets

jus shop around and luck sum places run out of premium not 98..and apparently shell's premium is 87..not 95 or 96. so it beats votex which is ova rated

[rev210]

Toluene rotting fuel lines:

............actually yes it does and your whole car will start rotting shortly afterwards and then the neigbours dog too but, no one liked it barking at night anyway so we are all happy again. Although without fuel lines and a car.

It also will cause you girlfriend to leave you and it will lose you your job.

[Josh]

... seriously... someone mentioned it not long ago - have you heard anything along those lines?

[KeeFy]

Rotting fuel lines? *shudders* Contemplates trying out tolulene now.

[Br4nchi3]

..and apparently shell's premium is 87..not 95 or 96. so it beats votex which is ova rated

<{POST_SNAPBACK}>

Nah your wrong dude, don't know where you got that info. I'm telling you all now.. normal unleaded petrol is 91-92 RON, most premiums are 95-96 (VORTEX is 96) and BP Ultimate is 98.

Octane booster is pretty much useless guys. Yeah it helps a bit and most of them also clean out injectors and prevent knocking etc. But wont give you much of a performance gain.

Say you fill up with VORTEX (96RON), and you add in some octance boost which gives you "7-8 points", this will make your petrol 96.7 - 96.8 RON.

BP Ultimate still leads with 98RON.

10 points of octane boost = 1 RON.

Hope this helps

even IF it were true that fuel lines rot from tolulene

compare the cost effectiveness of replacing fuel lines, o-rings and fuel pump, with

rebuild of engine

hmm, tough choice. Seriously guys, dont listen to old wives tales, I have used tolulene, Rev210 has used tolulene, I know many people that regularly use tolulene (with other additives like avgas ) and NOT ONE of them, nor me has had any problems with rotting fuel lines

Next time someone tells you it rots fuel lines, ask them if its from personal experience, if they say no - its just a rumour, if they say yes, ask them how long they were using it until the fuel lines rotted, what percentages, and how old the fuel lines were to start with. I am sure they will get very vague about their answers at this point.
