SHELL optimax VS BP ultimate FUEL ! For DOHC VTEC

[ATSEK4]

I think it's very hard to find someone who use both BP and Ultimate on dyno

NO man.. not a dyno graph.. it is a graph showing comparison of shell bp and others.

in a car designed to run on 96 RON at best (the mirage), I fail to see how you can increase power/torque by moving to a higher octane. By advancing ignition - possibly

Yes, it was by changing the timing maps. By good power I mean in comparison to other 4G15's with the same mods. Unfortunatley I don't have the money to do back to back tuning on shell and BP... Anyway it would have to be a pretty big diffrence to make me go back to BP.

top up with some 105RON track fuel.
go half BP ultimate and 20l of the 105 spirit. Nothing will be better !

I'd rather pee in my tank than put Shell products in there again.

i totally agree!!! lol bp has always done it for me.. with all my cars from turbo 4's and 6's to turbo rotarys to hard tuned na 4's..

Not sure about 105...but you can buy the 100 ron from Shell... On the way to ipswich road..

[ENDLESS]

Not sure on other cars... but for Dc5r... modified with optimax is about the same speed as a stock with Ultima... with K20, the Ultima is a lot better...

[Civic Type R]

you can get 105 RON from some race supplier shops. Its about $5 / litre tho

vortex gold is 95 ron i think.. classed as their premium unleaded..
BUT caltex has now released vortex 98 which is 98 ron.. if u guys are caltex fans head over to www.caltex.com.au and theres a map showing caltex locations..
if ur in the eastern suburbs in nsw then coogee south and nth bondi seem to be the closest with vortex 98

is it good to buy fuel which has been sitting on store shelfs for awhile??

i've read that fuel deteriorates, some ppl i know actually goto trouble to ask the servo guy when did the last fuel tanker come in... it may be 105 RON at time of production but when you actually come round to using it may be alot less...

5bux a litre...
and i thought octane booster was a rip off

[Civic Type R]

its race fuel in which they use for the track GT series.
It gets turned over quite regularily - a lot more than u expect.

I'm not sure of the validity of the information they provided but I remember watching I think it was RPM about the control fuel for the V8 Supercars, Optimax.

A batch is produced and stored for the entire season so I guess the stability issues regarding the denaturing of octane is if the fuels are kept in conditions that alow it to deteriorate easily.

On the Optimax facts, it is actually 98.4 RON and guarenteed to keep its RON above 98 if stored under specific conditions for up to one year.
