bp Ultimate vs BP premium

Hey
Just wondering what u guys think in comparision of the new fuels coming out
There is a BP close by which does 95 Ron unleaded,
and one that i go past which doesn't do the 95 ron but does 98 ron
the 98 ron one at bp is like 8 cents more and the 95 ron is like 4 cents more than the standard 91 ron
I use only 95 ron these days as the difference between standard is minimal and yeah i rather do the car good.
The cars a 1986 celica sx,
What do u guys reckon i should be using??
Any benefits from the 98 ron that i could use?
Regards
Adrian

New?!?!
Anyway, it'll do bugger all unless your car is tuned for it. Performance-wise at least.

I wouldn't bother with the 98 octane - heaps more in cost.
Unless your car is pinging on the standard stuff it won't be worth it. You could advance timing a bit and run the good stuff, but then on a hot day and if you can only get normal petty your car will be pinging to the BS.
I've had 'fiddles' with my timing and just got it so it runs without pinging on the normal stuff (turned out being what the manufacturer recommendes 10 deg BTDC), although ocassionally I can hear it ping slightly under certain load conditions, but I may need clean out carbon deposits to fully get rid of it

yeah i dont think its 'that' much of a difference in some cars. I had an '87 barina for a few years and it made a fair bit of a differnce when i went from standard unleaded to optimax.
I find the more expensive fuels are better for engines that run at high speeds frequently (ie everyones' car here ahah).

I'm using 98RON in my RA60 with a whack of timing advance (3 times factory, hehe  ). I mainly did it for fuel economy, but a flat spot I had has also gone away.
My fuel economy has come down 2l/100km's, which more than offsets the initial purchase price.

The fuel economy is due to the fuel being "denser".
This would probably be the only noticable difference when using Optimax (not sure if Ultimate is the same density).
This is the reason why I said "performance-wise" in my first post.

acutally the density thing is only in reference to lower octane fuel..
typically, when you go to higher octane ratings, you decrease the amunt of energy stored and need to burn a larger volume of fuel (think alcohol)
initially when the higher octane stuff came out, it had less energy/volume and this could cause problems if mixtures go a little lean (we're talking 2 or 3% only)
the density thing basically means that you don't need to recalibrate the amount of fuel going in.. but you can still use more compression and advance..

Just out of curiosity, does anyone know if it is ilegal to run straight toluene? I know that it is basically whats in Octane Boost, but in pure form it burns nearly 100% clean, doesnt ping and has a ron of about 110. I know its exy too,well, $1/litre but just wondering.
Cheers

One of the other benifits of the name brand fuels (Ultimate, Optimax and Synergy) is that they have detergents in them.

Toluene is very bad for peoples health?
basically Toluene is Methyl-Benzene, and Benzene is a potent carcinogen.
off topic a bit, but here's an interesting MSDS for "Carby Cleaner"
http://www.wurth.com.au/msds/1893_100.htm
| Quote: |
TOLUENE
ES TWA: 100 ppm, 377 mg/m3; STEL: 150 ppm, 565 mg/m3 (Under review)
PROPOSED CHANGE
ES TWA 50 ppm, 188 mg/m3 SKIN
TLV TWA: 50 ppm, 188 mg/m3 SKIN A4
OES TWA: 50 ppm, 191 mg/m3; STEL: 150 ppm, 574 mg/m3 SKIN
MAK value: 50 ppm, 190 mg/m3
MAK Category II Peak Limitation: For substances with systemic effects
and with a half-life in humans ranging from two hours to shift-length.
Allows excursions of 5 times the MAK value, for 30 minutes (on average),
twice per shift.
MAK Group C: There is no reason to fear risk of damage to the developing
embryo when MAK and BAT values are observed.
IDLH Level: 500 ppm
Odour Threshold Value: 0.16-6.7 (detection), 1.9-69 (recognition)
NOTE: Detector tubes measuring in excess of 5 ppm, are available.
Exposure limits with "skin" notation indicate that vapour and liquid may be
absorbed through intact skin. Absorption by skin may readily exceed vapour
inhalation exposure. Symptoms for skin absorption are the same as for
inhalation. Contact with eyes and mucous membranes may also contribute to
overall exposure and may also invalidate the exposure standard.
High concentrations of toluene in the air produce depression of the
central nervous system (CNS) in humans. Intentional toluene exposure
(glue-sniffing) at maternally-intoxicating concentration has also produced
birth defects. Foetotoxicity appears at levels associated with CNS
narcosis and probably occurs only in those with chronic toluene-induced
kidney failure. Exposure at or below the recommended TLV-TWA is thought
to prevent transient headache and irritation, to provide a measure of
safety for possible disturbances to human reproduction, the prevention of
reductions in cognitive responses reported amongst humans inhaling
greater than 40 ppm, and the significant risks of hepatotoxic, behavioural
and nervous system effects (including impaired reaction time and
incoordination). Although toluene/ethanol interactions are well
recognised, the degree of protection afforded by the TLV-TWA among
drinkers is not known.

i don't know how many cubic metres of skin you have, but 200mg/cubic metre is only 0.2mls!!!!! probably not even one drop!!
remember those stories of mechanics washing grease off themselves with toluene? and dying over the next day or two?
and to anyone using 'octane boosters' be very careful when draining or working with tainted petrol.
to anyone using carby cleaner with bare hands and no respirator... ummm... get gloves and respirator
Cya, "Stewart the safety Nazi"
ps, anyone seen how much hydroflouric acid (HF) is in some "metal brightners" and "mag wheel cleaners" ?? enough to make your fingers turn black, die, and drop off

oh yeah, and you don't have to breathe toluene in... you absorb the VAPOUR thru your skin...
by the time you can smell it, you are probably already above the recommended exposure limits....

not to mention the fact straight toluene would probably burn out your valve seats in no time flat. and like stewart said, cancer time, but hell what isn't these days. if you must add it to fuel, a ratio of 1:7 is about right
what if your car pings even on bp ultimate cos u have high compression?  hehehe shake those pistons

Yeah unless I rev the shit out of my Lancer it can ping a lot when I'm not on 98 or 95 ron. In fact I have found recently it's pinging even on 98 ron sometimes. Stupid car. Needs a new engine.

I know it as 91 and 95 and 98 octane
Whats RON stand for
And what is a carcinogen (too lazy to search for trivial answer).

Hi,
I run 98RON. The engine pings less with this and seems to run happier. Happy engine, makes a happy me and I'll handle the few extra cents p/litre.
However, having said that, let me say this; I only filled my car up a few days ago, and it was the 2nd tank for the year. She don't do much kms. So, if I was doing 1000s of kays per annum, I may think differenty about the cost difference.
